WHAT IS VITAMIN
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. (www.nutritiondata.com/help/glossary#V)
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. (www.nutritiondata.com/help/glossary#V)
The high rate of natural production of
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
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. (www.vitamindcouncil.org)

people with low vitamin D levels might be twice as likely to suffer from a heart

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).
Vitamin D and Dementia: A Strong Association
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.
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
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.
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
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
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
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
Based on the most recent research, the
current recommendation is 35 IU’s of vitamin D per pound of body
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?

Reliable Way to Determine How Much Vitamin D You or Your Child Needs.

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.
The Wonder Vitamin That May Help You
Prevent 16 Types of Cancer
October 22, 2011
Theories linking vitamin D deficiency to cancer
have been tested and confirmed in more than 200 epidemiological studies, and
understanding of its physiological basis stems from more than 2,500
laboratory studies. Optimizing your vitamin D levels could help you to
prevent at least 16 different types of cancer including pancreatic, lung,
ovarian, prostate, and skin cancers. Overall, optimal vitamin D levels can
cut cancer risk by as much as 60 percent, according to one large-scale,
randomized, placebo-controlled study.

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

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,

vitamin D levels, but it was too early to tell whether this improved their

Why the New Vitamin D Recommendations Spell Disaster For Your Health
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."

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 Segala07/15/2009)

Vitamin D More Effective Than Previously Known
Editorial by Bill Faloon of Life Extension
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
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.
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

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’.
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
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
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.
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

Well adults and adolescents should

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
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
