Vitamin D3 (Cholecalciferol): Vitamin D is a fat-soluble vitamin that helps maintain blood levels of calcium, by increasing absorption from food and reducing urinary calcium loss. Both functions help keep calcium in the body and therefore spare the calcium that is stored in bones. Vitamin D may also transfer calcium from the bone to the blood, which may actually weaken bones. Though the overall effect of vitamin D on the bones is complicated, some vitamin D is certainly necessary for healthy bones and teeth. Vitamin D is also produced by the human body during exposure to the ultraviolet rays of the sun. However, seasonal changes, latitude, time of day, cloud cover, smog, and sunscreen can all affect UV exposure. (

Vitamin D deficiency is more common in northern latitudes, making vitamin D supplementation more important for residents of those areas. Vitamin D plays a role in immunity and blood cell formation and also helps cells differentiate—a process that may reduce the risk of cancer. From various other studies, researchers have hypothesized that vitamin D may protect people from multiple sclerosis, autoimmune arthritis, and juvenile diabetes. Vitamin D is also necessary to maintain adequate blood levels of insulin. Vitamin D receptors have been found in the pancreas, and some evidence suggests that supplements may increase insulin secretion for some people with adult-onset diabetes. (

The high rate of natural production of vitamin D3 cholecalciferol (pronounced koh·luh·kal·sif·uh·rawl) in the skin is the single most important fact every person should know about vitamin D—a fact that has profound implications for the natural human condition.

Technically not a "vitamin," vitamin D is in a class by itself. Its metabolic product, calcitriol, is actually a secosteroid hormone that targets over 2000 genes (about 10% of the human genome) in the human body. Current research has implicated vitamin D deficiency as a major factor in the pathology of at least 17 varieties of cancer as well as heart disease, stroke, hypertension, autoimmune diseases, diabetes, depression, chronic pain, osteoarthritis, osteoporosis, muscle weakness, muscle wasting, birth defects, periodontal disease, and more. (

Many people are supplementing with 1,000 to 2,000 IU of vitamin D3 daily, but according to the Vitamin D Council that may not be enough. And blood testing is the only way to know for sure whether your regimen is appropriate. It’s hard to know exactly how much vitamin D your body is making from sun exposure. It depends on factors like what latitude you live at, your skin color and how much skin you expose for how long. And your needs may change according to the seasons, your age, your health and your weight. The Vitamin D Council suggests taking 5,000 IU of Vitamin D3 every day for three months, then get a 25-hydroxyvitamin D test. Optimal blood levels are between 50-80 ng/mL year-round. Adjust your dosage up or down according to your results. (

A study published in the Journal of the American College of Cardiology indicated that people with low vitamin D levels might be twice as likely to suffer from a heart attack or stroke than those with higher vitamin D levels.

A University of California San Diego study found a 50 percent drop in colon cancer and a 30 percent decreased risk of ovarian and breast cancer with increased intake of vitamin D, which also reduced prostate cancer risk in men by 43 percent.


Link Found Between Dementia and Vitamin D Deficiency

Thursday 7 August 2014 - 2am PST

From: Medical News Today

In what is regarded as the first large, population-based study of its kind, a team of researchers has found a link between vitamin D consumption and the risk of developing dementia. Older people who do not get enough vitamin D could double their risk of developing the condition. Vitamin D is important for the body's immune function, growth and repair of bones, and normal calcium and phosphorus absorption. It can be obtained from fish, milk, eggs and cheese.

Dementia is a collective term used to describe the problems that people with various underlying brain disorders can have with their memory, language and thinking. Alzheimer's disease is the best known and most common disorder under the umbrella of dementia.

Alzheimer's disease is the sixth leading cause of death in the US and is believed to currently affect 5.3 million Americans, according to the Centers for Disease Control and Prevention (CDC). It is most common in people aged over 65, in which a tenth of the population has the condition.

The authors of the study, published in Neurology, state that low concentrations of vitamin D are associated with the development of Alzheimer's disease. Worryingly, there are high rates of vitamin D deficiency in older adults - the group most at risk from developing dementia.

The CDC report that one third of the US population do not get sufficient amounts of vitamin D, with 8% of the population at risk of vitamin D deficiency. Vitamin D is obtained from sun exposure and foods such as milk, eggs, cheese and fatty fish.


Vitamin D: Powerful Cancer Protection

Posted: Wednesday, Aug 20th, 2014
BY: Joel Fuhrman, M.D.

The most recent research on blood vitamin D status and cancer survival suggests that vitamin D adequacy reduces the risk of death in breast, colorectal, lung and prostate cancer, leukemia and lymphomas and all cancers combined.

Research on vitamin D supplementation, summarized in a 2014 Cochrane analysis, found that supplementation with vitamin D3 was associated with reduced risk of cancer mortality.

The idea that vitamin D could protect against cancers arose in 1980, based on an earlier observation that colon cancer mortality was the highest in geographical areas exposed to the least amounts of sunlight. Several more studies of geographical variations in cancers have since found the same result: inverse relationships exist between sun exposure and 24 types of cancer, including the most common cancers — those of the breast, colon, rectum and prostate. Because most people’s primary vitamin D source is sunlight, vitamin D insufficiency is thought to be one reason for the cancer survival disparities that exist between African Americans and white Americans (darker skin is less efficient at producing vitamin D in response to UV rays).


How Much Vitamin D Do You Need?

Men's Journal

– Melaina Juntti

April 14, 2015

Any doctor will tell you that your body needs vitamin D to function properly. But if you ask three different docs exactly how much D you need, you'll likely get as many answers. One might say 600 IU per day, which is what the Institute of Medicine suggests, while another may recommend 1,000 IU. And then the third doctor might aim much higher, advocating for 5,000 or even 10,000 IU each day.

This practice has sparked fiery debate among medical professionals in recent years, as vitamin D has been thrust into the spotlight. A fat stack of research now shows that vitamin D keeps our brains healthy, our bones strong, and possibly even helps stave off cancer. And, on the flip side, several studies have linked vitamin D deficiency to various diseases. Nobody really argues these facts. But what doctors are sparring over — and what's causing the huge range in recommended daily vitamin D intakes — is how many people are actually deficient in the first place. The latest news gives the strongest evidence yet that those pushing for more vitamin D were right all along.

Over the past year, two separate groups of researchers, each dissatisfied with the Institute of Medicine's low recommended daily allowance for 600 IU a day, decided to dig back into the studies the IOM had used to come up with its recommendation. Both teams discovered that the IOM had made a giant statistical error. We'll spare you the gritty mathematical details (check them out here if you're interested), but basically, it appears that the IOM miscalculated the amount of vitamin D it takes for 97.5 percent of the population to not be deficient. The researchers insist that when the math is done correctly, the evidence shows that the RDA should be 7,000 IU per day, not 600 IU. In other words, you probably need to be taking a daily supplement of D.

The reason we're severely lacking vitamin D nowadays, much more so than even our parents were, is because we're missing out on the number-one source of vitamin D: the sun. "Vitamin D is a pro-hormone made in the skin upon exposure to sunlight, and production of it is rapid and robust," Cannell says. "Within 10 to 20 minutes without wearing sunscreen, people make between 10,000 and 20,000 IU. But because of widespread sunscreen use, total sun avoidance, and our increasingly indoor lifestyles, our vitamin D levels have fallen drastically."

Let's be clear: Skin cancer is still a very valid concern, as is sunburn, which can permanently damage your skin and cause wrinkles. So nobody is saying it's okay to slather on tanning oil and bake on the beach for hours. However, many experts now think that the long-held advice to never, ever set foot outdoors without wearing sunscreen needs to go.

"SPF 30 sunscreen decreases your body's ability to make vitamin D by 98 percent," says Dr. Michael Holick, an endocrinologist and vitamin D researcher at Boston University School of Medicine. "You always want to protect your face with sunscreen to decrease your chances of non-melanoma skin cancers and wrinkling. However, the rest of your body can handle some sun exposure."

ALSO: Magnesium, the Missing Mineral

But running around shirtless in order to get your body making vitamin D obviously won't fly in the wintertime, early spring, or late fall. And even during the summer, on the weekdays, it can be tough to get out midday when the sun is high enough to get vitamin D. That's why so many doctors recommend taking a supplement every day. 

Both Cannell and Holick suggest most people take a vitamin D supplement. Holick says to take at least 2,000 IU per day year-round; he personally takes 4,000. Cannell thinks everyone should take 5,000 IU. And although you technically don't need to supplement on the days that you know you'll be outside when the sun is high, "it's just easier to take it every day than to try to remember when and not to," Holick says.


As a rule of thumb, 1,000 IU's will raise 25(OH)D levels by about 10 ng/mL 

Human toxicity probably begins to occur after chronic daily consumption of approximately 40,000 IU/day (100 of the 400 IU capsules).
Humans make at least 10,000 units of Vitamin D within 30 minutes of full body exposure to the sun.

50,000 IU's is equivalent to approximately 1.25 mg


According to the Vitamin D Council

The Dosage Recommended

John Jacob Cannell MD  Executive Director 2008.10.01

If you use suntan parlors once a week or if you live in Florida and sunbathe once a week, year-round, do nothing. However, if you have little UVB exposure, my advice is as follows: healthy children under the age of 1 years should take 1,000 IU vitamin D3 per day—over the age of 1, 1,000 IU vitamin D3 per every 25 pounds of body weight per day. Well adults and adolescents should take 5,000 IU vitamin D3 per day. Around 2–3 months later have a 25-hydroxyvitamin D blood test, either through ZRT or your doctor.

Start supplementing with the vitamin D before you have the blood test. Then adjust your dose so your 25(OH)D level is between 50–80 ng/ml (125–200 nmol/L), summer and winter. But remember, these are conservative dosage recommendations. Most people who avoid the sun—and virtually all dark-skinned people—will have to increase their dose once they find their blood level is still low, even after two months of the above dosage, especially in the winter. Some people may feel more comfortable ordering the blood test before they start adequate doses of vitamin D. We understand. Test as often as you feel the need to, just remember, no one can get toxic on the doses recommended above and some people will need even more.


Vitamin D and Dementia: A Strong Association

Last updated: 

For the study, the researchers tested 1,658 dementia-free people aged over 65 who had participated in the US population-based Cardiovascular Health Study. The vitamin D levels in their blood were tested, and they were followed up for an average of 5.6 years.

During this follow-up period, 171 of the participants developed dementia and 102 participants developed Alzheimer's disease. The researchers found the participants with low levels of vitamin D were 53% more likely to develop dementia, and those who were severely deficient were 125% more likely, when compared with participants with regular levels of vitamin D.

Similarly, participants with low levels of vitamin D saw a 70% increased risk of developing Alzheimer's disease, and those with severe deficiency had an increased risk of 120%, again when compared with participants with normal levels of the vitamin.

Study author David J. Llewellyn, of the University of Exeter Medical School in the UK, was surprised by the extent of their results, saying, "we actually found that the association was twice as strong as we anticipated."

The results of the study remained the same even after adjusting for other variables - such as alcohol consumption, smoking and education - that could affect the risk of developing dementia.

Vitamin D Toxicity Rare in People Who Take Supplements, Mayo Clinic Researchers Report

Released: 29-Apr-2015 3:05 PM EDT  Mayo Clinc

Newswise — Rochester, Minn. – Over the last decade, numerous studies have shown that many Americans have low vitamin D levels and as a result, vitamin D supplement use has climbed in recent years. Vitamin D has been shown to boost bone health and it may play a role in preventing diabetes, cancer, cardiovascular disease and other illnesses. In light of the increased use of vitamin D supplements, Mayo Clinic researchers set out to learn more about the health of those with high vitamin D levels. They found that toxic levels are actually rare.

Their study appears in the May issue of Mayo Clinic Proceedings.

A vitamin D level greater than 50 nanograms per milliliter is considered high. Vitamin D levels are determined by a blood test called a serum 25-hydroxyvitamin D blood test. A normal level is 20-50 ng/mL, and deficiency is considered anything less than 20 ng/mL, according the Institute of Medicine (IOM).

The researchers analyzed data collected between 2002 and 2011 from patients in the Rochester Epidemiology Project, a National Institutes of Health-funded medical records pool that makes Olmsted County, Minn., the home of Mayo Clinic, one of the few places worldwide where scientists can study virtually an entire geographic population to identify health trends.

Of 20,308 measurements, 8 percent of the people who had their vitamin D measured had levels greater than 50 ng/mL, and less than 1 percent had levels over 100 ng/mL.

“We found that even in those with high levels of vitamin D over 50 ng/mL, there was not an increased risk of hypercalcemia, or elevated serum calcium, with increasing levels of vitamin D,” says study co-author Thomas D. Thacher, M.D., a family medicine expert at Mayo Clinic.

Hypercalcemia, or high blood calcium, can occur when there are very high levels of vitamin D in the blood. Too much calcium in the blood can cause weakness, lead to kidney stones, and interfere with the heart and brain, and even be life threatening.

The Mayo researchers also found that women over age 65 were at the highest risk of having vitamin D levels above 50 ng/mL. The result was not surprising because that's a group that often takes vitamin D supplements, Dr. Thacher says.

Another notable outcome: The occurrence of high vitamin D levels over 50 ng/mL increased during the 10-year period of the study, from nine per 100,000 people at the start of the study up to 233 per 100,000 by the end.

“We were surprised by that degree of dramatic increase in vitamin D levels,” Dr. Thacher says.

Only one case over the 10-year study period was identified as true acute vitamin D toxicity; the person's vitamin D level was 364 ng/mL. The individual had been taking 50,000 international units (IU) of vitamin D supplements every day for more than three months, as well as calcium supplements. The IOM-recommended upper limit of vitamin D supplementation for people with low or deficient levels is 4,000 IU a day.

It's important for doctors to ask their patients about the doses of vitamin D supplements that they are using, Dr. Thacher says, because even capsules containing as much as 50,000 IU of vitamin D are available without prescription. If taken on a daily basis, that amount could lead to toxicity.

Some natural sources of vitamin D include oily fish such as mackerel and salmon, fortified milk, and sunlight.

“Our bodies will naturally produce vitamin D when our skin is exposed to sunlight, however, we don't recommend excessive exposure to sun due to the risk of skin cancer,” Dr. Thacher added.

In an accompanying editorial in Mayo Clinic Proceedings, Dr. Michael F. Hollick, Ph.D., M.D., describes vitamin D's dramatic medical history, the need for judicious dosing, but the importance of vitamin D supplementation in those with low or deficient levels.

“The evidence is clear that vitamin D toxicity is one of the rarest medical conditions and is typically due to intentional or inadvertent intake of extremely high doses,” writes Hollick, a professor of medicine, physiology and biophysics at Boston University School of Medicine.

The study was made possible by the resources of the Rochester Epidemiology Project, which is supported by the National Institute on Aging. The study was also supported by the Mayo Clinic Center for Clinical and Translational Science through a grant from the National Center for Advancing Translational Sciences. Dr. Thacher is a consultant for Biomedical Systems. 



Low Vitamin D Levels Increase Risk Of Pancreatic Cancer

First Posted: Apr 30, 2015 06:04 PM EDT


People who live in cloudy areas where there is relatively little sunlight may have an increased risk of pancreatic cancer because they are not receiving a sufficient amount of vitamin D, according to recent findings published in the Journal of Steroid Biochemistry and Molecular Biology.

"If you're living at a high latitude or in a place with a lot of heavy cloud cover, you can't make vitamin D most of the year, which results in a higher-than-normal risk of getting pancreatic cancer," said first author Cedric F. Garland, DrPH, adjunct professor in the Department of Family Medicine and Public Health and member of UC San Diego Moores Cancer Center, in a news release. He is an adjunct professor with the University of California, San Diego School of Medicine's Department of Family Medicine and Public Health.

"People who live in sunny countries near the equator have only one-sixth of the age-adjusted incidence rate of pancreatic cancer as those who live far from it," Garland added. "The importance of sunlight deficiency strongly suggests - but does not prove - that vitamin D deficiency may contribute to risk of pancreatic cancer."

Of course, vitamin D doesn't just come from sunlight. You can get it from certain foods, too, including cheese, a number of fatty fishes, milk, some juices, etc. And there are also supplements that can help out as well. However, direct outdoor exposure to the sun is an easy way to boost the body's overall production of vitamin D and a bit more natural, as well.

For the study, researchers linked higher vitamin D levels to lower concentrations of breast and colorectal cancer. They also reported a similar connection to pancreatic cancer.

After examining information on over 100 countries, they found that the adjustment of outcomes were also done in an order that was not thrown off by other risk factors including smoking, alcohol consumption and obesity.

Vitamin D – Could It Stop 'Modern’ Diseases?

As scientists show a link between low Vitamin D and Alzheimer's, an award-winning writer writes that Vitamin D deficiency is behind the increase in conditions such as MS, diabetes, schizophrenia and asthma


4:00PM BST 07 Aug 2014

This article was first published on March 10, 2014 and has been republished after scientists have shown that sunshine could help stave off dementia.

Scientists often liken the process of discovery to doing a jigsaw. At first, few pieces fit and the picture is a mystery. Then suddenly two or three pieces lock together and an image starts to take shape.

This is what is happening in the study of apparently unrelated, chronic diseases such as multiple sclerosis, schizophrenia, diabetes and asthma. These conditions are increasingly common both in the UK and elsewhere; their causes have puzzled doctors and scientists for decades.

Now pieces of the jigsaw are starting to fit together – and they focus on vitamin D which is produced naturally in the skin when exposed to sunlight.

A deficiency in this crucial vitamin, thanks to our increasingly indoor lifestyles, is already blamed for the reappearance of rickets, the painful and deforming bone disease in children, in the UK. But gradually, evidence is emerging that links low vitamin D levels to a rise in a whole host of “modern” diseases, some of which were virtually unheard of in the pre-industrial era.



Low Vitamin D Levels Linked to Premature Death

The debate over vitamin D continues, and the latest research has found a link between low levels of the fat-soluble vitamin and premature death, Medical News Today reported.

In a new study published in the American Journal of Public Health, researchers from the University of California-San Diego conducted a review of 32 studies that analyzed participants’ blood levels of vitamin D and mortality rates. The studies included 566,583 participants from 14 countries, who had an average age of 55.

Researchers found that participants with lower levels of 25-hydroxyvitamin D— the main form of vitamin D found in human blood— were twice as likely to have a premature death, compared to those with higher blood levels of 25-hydroxyvitamin D.

Furthermore, researchers found that approximately half of the participants who were at risk for early death had a vitamin D blood level of 30 ng/ml. An estimated two-thirds of the U.S. population has a blood vitamin D level below 30 ng/ml.

Is Inadequate Vitamin D Implicated in Fibromyalgia, Multiple

 Sclerosis, and Parkinson's?

Sturgeon Bay, WI (PRWEB) May 29, 2014

Fibromyalgia is characterized by pervasive chronic pain and fatigue. Sturgeon Bay, Wisconsin Chiropractor and Naturopath Dr. J G Moellendorf, DC, ND, LCP notes that many fibromyalgia sufferers also experience other symptoms such as stiffness when awaking, sleep disorders, inability to concentrate, anxiety, and depression. This can have major effects on one's quality of life, social interaction, and ability to hold employment. Treatment for the various symptoms can be very expensive, for which there is no total cure.

Researchers have found that vitamin D reduces pain intensity in many chronic conditions. A research team led by Dr. Florian Wepner at Orthopaedic Hospital, Speising, Vienna, Austria found that many fibromyalgia sufferers had low vitamin D blood levels. They theorized that if vitamin D levels could be raised, patients' pain levels might decrease. A randomized controlled trial was done with 30 women with fibromyalgia and low blood levels of vitamin D, who were randomly assigned to either a treatment or control group. The goal for the treatment group was to supplement with vitamin D to bring the blood level into the normal range for a period of at least 20 weeks. Blood levels were reevaluated at 5 and 13 weeks, with a readjustment of the dose as needed. Blood levels of vitamin D were assessed again at 25 weeks, at which time supplementation was stopped, with a final assessment 24 weeks after stopping the supplementation.

Recommended Daily Intake for Optimal Health

 Dr. Joseph Mercola    October 10 2009

Based on the most recent research, the current recommendation is 35 IU’s of vitamin D per pound of body weight.

So for a child weighing 40 pounds, the recommended average dose would be 1,400 IU’s daily, and for a 170-pound adult, the dose would be nearly 6,000 IU’s.

However, it’s important to realize that vitamin D requirements are highly individual, as your vitamin D status is dependent on numerous factors, such as the color of your skin, your location, and how much sunshine you’re exposed to on a regular basis.

So, although these recommendations may put you closer to the ballpark of what most people likely need, it is simply impossible to make a blanket recommendation that will cover everyone’s needs.

So how do you ensure optimal vitamin D levels for yourself, your child, and aging parents?

Clear Brain Plaques with This Nutrient

By RealAge

September 30, 2011


If your mother gave you vitamin D-rich cod liver oil when you were a child, she may have been way ahead of her time.

A new animal study from Japan suggests that vitamin D may help clear the brain of amyloid beta, a toxic protein-like compound that accumulates in the brains of Alzheimer's patients.

Human Research Support
This animal study validates the results of a previous study done in human Alzheimer's patients. In the human study, vitamin D together with curcumin -- a chemical found in turmeric spice -- appeared to stimulate the immune system in a way that helped clear the brain of toxic amyloid beta. But this new animal research suggests that vitamin D alone may be able to do that job nicely. Even more amazing, the lab animals that received vitamin D were able to remove a significant amount of amyloid beta buildup in their brains, literally overnight. It seems the vitamin may somehow regulate production of transporter proteins that ferry amyloid beta across the blood-brain barrier and out of the brain. Pretty exciting stuff.

Vitamin D and breast health

Posted: October 12, 2011 - 12:11am

Vitamin D has received a lot of attention lately. We know Vitamin D is important for health by promoting the absorption of calcium from the intestines. If Vitamin D levels are too low, or deficient, adequate calcium cannot be absorbed. Vitamin D is necessary for bone growth during childhood and adolescence, bone healing for fractures, and together with calcium, Vitamin D helps protect older adults from weakening of the bones, or osteoporosis.

Vitamin D has other important roles in the body. This vitamin is important for regulating the growth of cells, preserving immune function, and reducing inflammation. Vitamin D has also been shown to help stabilize various genes and our DNA. Recent studies support Vitamin D for breast cancer prevention. Vitamin D acts as a hormone to help stabilize cell growth in the breast, and may help reduce the risk of breast cancer. We know there is an increased incidence of Vitamin D deficiency (or low Vitamin D levels), in women who are diagnosed with breast cancer. Maintaining normal Vitamin D levels after a diagnosis of breast cancer is important, and may help stabilize breast tissue, and reduce the risk of recurrence. We also know the treatment of breast cancer has been associated with Vitamin D deficiency, particularly in women who need anti-estrogen medication. Studies have shown that many of the musculo-skeletal symptoms in women, particularly in women taking anti-estrogen medication, may be relieved by normalizing the level of Vitamin D. This is exciting and new information, and helps us in our ability to care for patients, and maintain a good quality of life during breast cancer treatment.

Vitamin D May Lower Parkinson's Risk

Low Levels of Vitamin D Linked to Higher Risk of Parkinson’s Disease, Researchers Say
By Bill Hendrick  WebMD Health News

July 13, 2010 -- Higher levels of vitamin D may reduce the risk of developing Parkinson’s disease, a new study suggests.

The finding builds on previous research linking low vitamin D levels to Parkinson’s, and could mean that getting more sunlight and assuring an adequate dietary intake of vitamin D may help some people ward off the neurological disorder.

Paul Knekt, DPH, and colleagues at the National Institute for Health and Welfare in Helsinki, Finland, studied 3,173 Finnish men and women between the ages of 50 and 79 who did not have Parkinson’s when the research project began in 1978 to 1980.

Participants filled out questionnaires and were interviewed about socioeconomic and health backgrounds and underwent blood tests to be analyzed for vitamin D.

After 29 years, 50 of the participants had been diagnosed with Parkinson’s disease.

Participants who had the highest levels of serum vitamin D had a 67% lower risk of developing Parkinson’s than those in the lowest 25% of the group studied.

“Despite the overall low vitamin D levels in the study population, a dose-response relationship was found,” the authors write. “This study was carried out in Finland, an area with restricted sunlight exposure, and is thus based on a population with a continuously low vitamin D status.”

Therefore, the average serum vitamin D levels in the entire studied population were about 50% of what is considered optimal.



What Do You Lack? Probably Vitamin D

Vitamin D promises to be the most talked-about and written-about supplement of the decade. While studies continue to refine optimal blood levels and recommended dietary amounts, the fact remains that a huge part of the population — from robust newborns to the frail elderly, and many others in between — are deficient in this essential nutrient.
If the findings of existing clinical trials hold up in future research, the potential consequences of this deficiency are likely to go far beyond inadequate bone development and excessive bone loss that can result in falls and fractures. Every tissue in the body, including the brain, heart, muscles and immune system, has receptors for vitamin D, meaning that this nutrient is needed at proper levels for these tissues to function well.

Studies indicate that the effects of a vitamin D deficiency include an elevated risk of developing (and dying from) cancers of the colon, breast and prostate; high blood pressure and cardiovascular disease; osteoarthritis; and immune-system abnormalities that can result in infections and autoimmune disorders like multiple sclerosis, Type 1 diabetes and rheumatoid arthritis.

The Vitamin-D Debate  

By Sanjay Gupta, M.D.  Monday, May. 18, 2009

About 10 to 15 minutes spent outside in full sun will give a fair-skinned person dressed only in his skivvies 10,000 to 20,000 IUs. Turns out the debate about how much vitamin D we need has intensified over the past 10 years. One part of the discourse focuses on the growing body of research that points to numerous health benefits of the chemical (actually a hormone): it can help prevent rickets in children and severe bone loss in adults and potentially lowers the risk of multiple sclerosis, juvenile diabetes, cancer, heart disease, colds and influenza. Amid all this new evidence, the Institute of Medicine (IOM) has assembled a panel of experts to re-evaluate just how much vitamin D we really need and can safely tolerate. Current IOM recommendations, set in 1997, are 200 IUs a day from birth to age 50 and a bit more after that. The upper limit of safety, according to the institute, is 2,000 IUs daily--too much can lead to, among other things, nausea and kidney stones--yet some vitamin-D proponents are pushing for up to 4,000 IUs a day for adults.

The researchers analyzed vitamin D levels in blood samples from 160 cancer patients. They found that 42 percent had insufficient levels of vitamin D (between 20 and 30 nanograms per milliliter of blood) and 32 percent had vitamin D deficiency (less than 20 ng/mL).

Among the participants, the average level of vitamin D was 24 ng/mL. Anyone who lay below this level were nearly three times more likely to have stage III cancer than those with higher levels of vitamin D.

These findings are only preliminary, and have not yet been peer-reviewed, but they suggest that vitamin D could play an important role in cancer in cancer prevention and treatment. It also goes hand in hand with previous research, which has indicated that vitamin D plays a role in regulating the spread and multiplication of cancer cells, and has anti-tumor properties.

According to study author Thomas Churilla, the researchers administered vitamin D to the participants with low vitamin D levels, but it was too early to tell whether this improved their prognosis.

Good sources of vitamin D include fatty fish such as salmon or mackerel, milk, and certain breakfast cereals. Vitamin D can also be absorbed through direct exposure to sunlight.

The research was presented at the American Society for Radiation Oncology.

Vitamin D study suggests that pale people need supplements

By Ryan Jaslow  Oct 4, 2011

(CBS News) Pale? Pasty? A new study suggests you might benefit from a vitamin D supplement.

The English study suggests that pale people tend to be deficient in the "sunshine" vitamin and that without supplements they're unlikely to get their levels up without getting sunburned.

That can put them at risk for bone loss, heart disease, and poorer survival from breast cancer, according to the study's authors.
"This should be considered for fair-skinned people living in a mild climate like the UK and melanoma patients in particular," study author Dr. Julia Newton-Bishop, a cancer researcher at the University of Leeds, said in a written statement.

For the study - published in the Oct. 4 issue of Cancer Causes and Control - researchers tested vitamin D levels in 1,200 people and found 730 of them had below-normal levels. Levels were lowest in fair-skinned folks.

Vitamin D is associated with healthy bones, and levels below 25 nmol/L s are considered deficient. The study defined 60nmol/L as the normal vitamin D level, which research suggests can be associated with healthy benefits.

The National Institutes of Health recommends vitamin D levels of 50 nmol/L and above for adequate bone health.

Think you're not getting enough vitamin D?

Besides supplements, foods including cod liver oil, salmon, and mackerel contain the daily value of vitamin D, while foods like, tuna, milk, yogurt, and eggs contain some amounts of the vitamin.

Sara Hiom, director of health information at Cancer Research U.K, said in the statement, "If you are worried about your vitamin D levels, our advice is to go see your doctor."

The NIH's office of dietary supplements has more on vitamin D.

Tired? Rundown? Check Your Vitamin D

Posted - 6/15/2010 at 10:31AM

TUCSON - Vitamin D is known as the sunshine vitamin, because sunlight exposure to skin is the best and only natural source for it. It's known to be essential for bone health, but research shows it's also crucial for fighting all kinds of diseases.

Todd Whitthorne, a health and wellness expert said, "We're finding that when we measure thousands of patients, the vast majority of them are low."

And Dr. Richard Honaker, a family practice physician, sees the same trends, "If you're low on vitamin D, your immune system does not function as well, or you're more susceptible to infections. There's a greater incidence of heart attacks and strokes in people that are vitamin D deficient versus people who are okay on their vitamin D levels."

How to Get the Most Out of Your Vitamin D Supplement

 Triston Sanders - Medical Anchor

May 10, 2010

Your body may make better use of a vitamin D supplement if you take it with your largest meal.
Researchers at the Cleveland Clinic examined 17 patients with Vitamin D deficiency.
Over a period of two to three months, the patients were told to take Vitamin D supplements with the biggest meal they ate each day. This boosted the level of Vitamin D in their blood by an average of 56%, the researchers said.
The study was recently published in the Journal of Bone and Mineral Research.


Why the New Vitamin D Recommendations Spell Disaster For Your Health

By Dr. J. Mercola | December 11, 2010

In their latest vitamin D report, the Institute of Medicine's Food and Nutrition Board (FNB) claims the only evidence for the benefit of vitamin D they could document was the improvement of bone health.

How they could come to this conclusion is truly beyond belief, because there are literally hundreds if not thousands of studies showing that it benefits dozens if not hundreds of clinical conditions.

Even on Formula, Babies Not Getting Enough Vitamin D.......

HOUSTON, TX - May 18, 2009 - Current recommendations for Vitamin D were called "grossly inadequate" at the American Association of Clinical Endocrinologists (AACE) 18th Annual Meeting & Clinical Congress. "National recommendations from the Food and Nutrition Board are 400 to 600 International Units (IU) a day," Neil Binkley, MD, an Associate Professor in Geriatrics and Endocrinology at the University of Wisconsin said. "That's simply not enough." "Experts recommend somewhere between 1500 to 2600 IU daily," Dr. Binkley said. "It's considered a very safe vitamin. One would need daily doses of 40,000 IU or higher before seeing negative side effects."

Dr. John  Cannell MD is a psychiatrist at Atascadero State Hospital in California, a maximum security hospital for psychiatric patients.  In 2005, an influenza A epidemic broke out in the hospital.  One by one, each ward became infected as patients came down with chills, fever, cough, and severe body aches. Only one ward in the hospital remained free of infection — Dr. Cannell’s.  Why was this so? His patients intermingled with patients from other wards and were not noticeably different in their age, health, or medical treatment. The only difference that could be discerned was that Dr. Cannell’s patients had been receiving a daily dose of 2000 IU of vitamin D for several months. That’s it.  All of his patients took vitamin D and not one caught the flu!  (Melanie Segala 07/15/2009)



Vitamin D Deficiency is Why You Get Flu!

Posted by Dr. Mercola |  From:  |  March 25,  2010

Taken from the above article:

Based on the latest research, many experts now agree you need about 35 IU’s of vitamin D per pound of body weight. This recommendation also includes children, the elderly and pregnant women.

However, keep in mind that vitamin D requirements are highly individual, as your vitamin D status is dependent on numerous factors, such as the color of your skin, your location, and how much sunshine you’re exposed to on a regular basis. So, although these recommendations may put you closer to the ballpark of what most people likely need, it is simply impossible to make a blanket recommendation that will cover everyone’s needs.

The only way to determine your optimal is to get your blood tested. Ideally, you’ll want to maintain a vitamin D level of 50-65 ng/ml year-round.



Vitamin D More Effective Than Previously Known

Editorial by Bill Faloon of Life Extension Foundation:

A large number of new vitamin D studies have appeared in the scientific literature since I wrote my plea to the federal government. These studies don’t just confirm what we knew 16 months ago—they show that optimizing vitamin D intake will save even more lives than what we projected.


For instance, a study published in June 2008 showed that men with low vitamin D levels suffer 2.42 times more heart attacks. Now look what this means in actual body counts.

Each year, about 157,000 Americans die from coronary artery disease-related heart attacks.4 Based on this most recent study, if every American optimized their vitamin D status, the number of deaths prevented from this kind of heart attack would be 92,500.

To put the number of lives saved in context, tens of millions of dollars are being spent to advertise that Lipitor® reduces heart attacks by 37%. This is certainly a decent number, but not when compared with how many lives could be saved by vitamin D. According to the latest study, men with the higher vitamin D levels had a 142% reduction in heart attacks.

What Is Vitamin D Deficiency Anyway...

Naturally, this would be the first question to answer before we can actually TREAT vitamin D deficiency. I’ve answered this question on the Normal Vitamin D Level page, and you should go there right now to find out what your vitamin D level SHOULD be- and the answer is NOT the same answer that is on your lab sheet.

The lab sheet does not provide you with what the ‘optimal’ Vitamin D Levels are. And many researchers believe that the low level on your lab sheet is WAY too low and should be considered “vitamin D Insufficiency” rather than ‘Low Normal Vitamin D Level’.

Despite the argument for D3 that was made, the D2 will certainly not harm you and will be effective at correcting your deficiency. If, however, you read the argument and prefer not to take D2 (a good choice), then going out and buying Vitamin D Supplements in the form of Vitamin D3 is really the best choice.

Either way, you SHOULD be using Vitamin D3 for your Daily Vitamin D Requirements after your regimen of Vitamin D Deficiency Treatment is finished.


The Right KIND of Vitamin D Supplements

Once you find out your Vitamin D Level, you need to decide what KIND of Vitamin D Supplements to take for your Vitamin D Deficiency Treatment. The BEST vitamin D supplements are those containing Vitamin D3- also known as Cholecalciferol, and you can see the Vitamin D 2 vs Vitamin D3 argument on that page. But if you are being followed by a doctor for your Vitamin D Deficiency Treatment, it’s likely that you will get a prescription for Vitamin d 2- also called ergocalciferol.


Vitamin D Deficiency Treatment Protocols

It is becoming more and more apparent that the Vitamin D Dosage required for a normal vitamin D level is MUCH higher than you might think. In fact, it is such a large amount that many doctors just won’t give enough to actually correct the deficiency- although this is changing as doctors are becoming more experienced with vitamin D deficiency treatment.  

Vitamin D Deficiency Treatment Protocols


Most Adults

Most Children aged 1 to 18


Dr. Michael Holick

50,000 IU's D2 once/week for 8 weeks
Repeat if Level Less than 30 ng/ml

50,000 IU's D2 once/week for 8 weeks


Leventis, P.1; Kiely, P. D. W

300,000 IU Vitamin D3
Orally 3 times per year



The Use of Vitamin D in Clinical Practice

Up to 10,000 IU's per day



Vitamin D Council

Enough to get the Vitamin D Level
Between 50 -80 ng/ml

Enough to get the Vitamin D Level
Between 50 -80 ng/ml


If you have even mild Vitamin D Deficiency, it is likely that you will need to be taking approximately 50,000 IU’s per week for 4 to 12 weeks.

If you have SEVERE deficiency, then you may need to be taking Vitamin D Supplements as high as 50,000 IU’s per DAY for a month or even two months until getting a repeat Vitamin D Serum Level. Some doctors may even give a Vitamin D injection of 600,000 IU’s once a month for several months until your Vitamin D Level gets up to the ‘Optimal Range’ of 40 to 80 ng/ml.

While these doses may seem VERY high to those who are not used to them, they are all acceptable dosages for Vitamin D Deficiency Treatment. There is little risk of a Vitamin D Overdose as long as you are getting your Vitamin D Level checked every few months of treatment and then at least every year thereafter. In fact, there has NEVER been a documented case of Vitamin D Overdose on 10,000 IU’s per day or less, in an adult, even when taken for several years!

Read more:


50,000 IU's is equivalent to approximately 1.25 mg

As a rule of thumb, 1,000 IU's will raise 25(OH)D levels by about 10 ng/mL 

Human toxicity probably begins to occur after chronic daily consumption of approximately 40,000 IU/day (100 of the 400 IU capsules).
Humans make at least 10,000 units of Vitamin D within 30 minutes of full body exposure to the sun.


According to the Vitamin D Council

The Dosage Recommended

John Jacob Cannell MD  Executive Director 2008.10.01

If you use suntan parlors once a week or if you live in Florida and sunbathe once a week, year-round, do nothing. However, if you have little UVB exposure, my advice is as follows: healthy children under the age of 1 years should take 1,000 IU vitamin D3 per day—over the age of 1, 1,000 IU vitamin D3 per every 25 pounds of body weight per day. Well adults and adolescents should take 5,000 IU vitamin D3 per day. Around 2–3 months later have a 25-hydroxyvitamin D blood test, either through ZRT or your doctor.

Start supplementing with the vitamin D before you have the blood test. Then adjust your dose so your 25(OH)D level is between 50–80 ng/ml (125–200 nmol/L), summer and winter. But remember, these are conservative dosage recommendations. Most people who avoid the sun—and virtually all dark-skinned people—will have to increase their dose once they find their blood level is still low, even after two months of the above dosage, especially in the winter. Some people may feel more comfortable ordering the blood test before they start adequate doses of vitamin D. We understand. Test as often as you feel the need to, just remember, no one can get toxic on the doses recommended above and some people will need even more.


Today, the FNB has failed millions...

3:00 PM PST November 30, 2010
After 13 year of silence, the quasi governmental agency, the Institute of Medicine's (IOM) Food and Nutrition Board (FNB), today recommended that a three-pound premature infant take virtually the same amount of vitamin D as a 300 pound pregnant woman. While that 400 IU/day dose is close to adequate for infants, 600 IU/day in pregnant women will do nothing to help the three childhood epidemics most closely associated with gestational and early childhood vitamin D deficiencies: asthma, auto-immune disorders, and, as recently reported in the largest pediatric journal in the world, autism. Professor Bruce Hollis of the Medical University of South Carolina has shown pregnant and lactating women need at least 5,000 IU/day, not 600.

The FNB also reported that vitamin D toxicity might occur at an intake of 10,000 IU/day (250 micrograms/day), although they could produce no reproducible evidence that 10,000 IU/day has ever caused toxicity in humans and only one poorly conducted study indicating 20,000 IU/day may cause mild elevations in serum calcium, but not clinical toxicity.

Viewed with different measure, this FNB report recommends that an infant should take 10 micrograms/day (400 IU) and a pregnant woman 15 micrograms/day (600 IU). As a single, 30 minute dose of summer sunshine gives adults more than 10,000 IU (250 micrograms), the FNB is apparently also warning that natural vitamin D input - as occurred from the sun before the widespread use of sunscreen - is dangerous. That is, the FNB is implying that God does not know what she is doing.

Disturbingly, this FNB committee focused on bone health, just like they did 14 years ago. They ignored the thousands of studies from the last ten years that showed higher doses of vitamin D helps: heart health, brain health, breast health, prostate health, pancreatic health, muscle health, nerve health, eye health, immune health, colon health, liver health, mood health, skin health, and especially fetal health. Tens of millions of pregnant women and their breast-feeding infants are severely vitamin D deficient, resulting in a great increase in the medieval disease, rickets. The FNB report seems to reason that if so many pregnant women have low vitamin D blood levels then it must be OK because such low levels are so common. However, such circular logic simply represents the cave man existence (never exposed to the light of the sun) of most modern-day pregnant women.

Hence, if you want to optimize your vitamin D levels - not just optimize the bone effect - supplementing is crucial. But it is almost impossible to significantly raise your vitamin D levels when supplementing at only 600 IU/day (15 micrograms). Pregnant women taking 400 IU/day have the same blood levels as pregnant women not taking vitamin D; that is, 400 IU is a meaninglessly small dose for pregnant women. Even taking 2,000 IU/day of vitamin D will only increase the vitamin D levels of most pregnant women by about 10 points, depending mainly on their weight. Professor Bruce Hollis has shown that 2,000 IU/day does not raise vitamin D to healthy or natural levels in either pregnant or lactating women. Therefore supplementing with higher amounts - like 5000 IU/day - is crucial for those women who want their fetus to enjoy optimal vitamin D levels, and the future health benefits that go along with it.

For example, taking only two of the hundreds of recently published studies: Professor Urashima and colleagues in Japan, gave 1,200 IU/day of vitamin D3 for six months to Japanese 10-year-olds in a randomized controlled trial. They found vitamin D dramatically reduced the incidence of influenza A as well as the episodes of asthma attacks in the treated kids while the placebo group was not so fortunate. If Dr. Urashima had followed the newest FNB recommendations, it is unlikely that 400 IU/day treatment arm would have done much of anything and some of the treated young teenagers may have come to serious harm without the vitamin D. Likewise, a randomized controlled prevention trial of adults by Professor Joan Lappe and colleagues at Creighton University, which showed dramatic improvements in the health of internal organs, used more than twice the FNB's new adult recommendations.

Finally, the FNB committee consulted with 14 vitamin D experts and – after reading these 14 different reports – the FNB decided to suppress their reports. Many of these 14 consultants are either famous vitamin D researchers, like Professor Robert Heaney at Creighton or, as in the case of Professor Walter Willett at Harvard, the single best-known nutritionist in the world. So, the FNB will not tell us what Professors Heaney and Willett thought of their new report? Why not?

Today, the Vitamin D Council directed our attorney to file a federal Freedom of Information (FOI) request to the IOM's FNB for the release of these 14 reports.

Most of my friends, hundreds of patients, and thousands of readers of the Vitamin D Council newsletter (not to mention myself), have been taking 5,000 IU/day for up to eight years. Not only have they reported no significant side-effects, indeed, they have reported greatly improved health in multiple organ systems. My advice, especially for pregnant women: continue taking 5,000 IU/day until your 25(OH)D is between 50-80 ng/mL (the vitamin D blood levels obtained by humans who live and work in the sun and the mid-point of the current reference ranges at all American laboratories). Gestational vitamin D deficiency is not only associated with rickets, but a significantly increased risk of neonatal pneumonia, a doubled risk for preeclampsia, a tripled risk for gestational diabetes, and a quadrupled risk for primary cesarean section.

Today, the FNB has failed millions of pregnant women whose as yet unborn babies will pay the price. Let us hope the FNB will comply with the spirit of "transparency" by quickly responding to our Freedom of Information requests.
