osteoporosis, diabetes, cardiovascular disease, and more!
Vitamin D3: The Wonder Vitamin!
The Importance of Vitamin D has been known for more than 75 yearsVitamin D reverses Rickets, a softening of the
bones in children, and osteomalacia (Rickets in adults)Rickets has been described since the middle-ages
and is the most common childhood disease in many developing countries
Predominant cause is poor diet and also lack of exposure to sunlight
Cod-liver oil, which contains vitamin D, has been used medicinally since the early 1800s
Other cures were found in the early 1920s Malnourished children were cured with whole milkOther studies found that Rickets could be cured
with long exposure to sunlight
The Importance of Vitamin D has been known for more than 75 years Nobel prize for chemistry awarded to Adolf Windaus in 1928 for
his “studies on the constitution of sterols and their connection with vitamins.”
Other scientists, before and after, contributed to our current understanding of how Vitamin D functions in the body and relates to human health1920s, rickets was caused by seasonal variations of sunlight1930s, various foods fortified with vitamin D to prevent rickets1970s, vitamin D was found to be metabolized in the liver and
kidneys and controlled calcium levels through its action in the intestines
1980s, vitamin D receptors are found in many tissues and organs and interface with more than 200 genes
1990s, low levels of vitamin D contribute to various illnesses and various conditions from autism and the common cold to cancer and chronic pain
2000s, higher dosages may be required to prevent and treat many diseases of the immune, cardiovascular and nervous systems
FDA will be increasing their daily dosage requirements for vitamin DFinal report with recommendations will be issued in 2010
Just what is Vitamin D?By definition, a vitamin is..
a substance regularly required by the body in small amounts
the body cannot make on its own is required to be supplied by the daily diet
Vitamin D can be absorbed from some foods…Highest amounts from cod liver oil, salmon,
mackerel, tuna, and sardinesLess amounts from whole milk, cheese, and eggsSome foods, such as such as milk, cereal, and
orange juice, are now fortified with small amounts of vitamin D to prevent Rickets
Vitamin D is also a hormoneVitamin D can be made by the body rather
being absorbed just from foodVitamin D3 form is made by the skin after
exposure to sunlight.It represents 90% of the vitamin D circulating
in our body!For nutritional and public health reasons,
vitamin D continues to be classified as a vitamin
The three important forms of vitamin D in the bodyVitamin D3 or Cholecalciferol
Is made in the skin after exposure to the sun. Non-toxic: Once you have made 20,000 units, a mechanism in
the skin destroys excess amounts25D or Calcidiol
A prehormone made from the vitamin D3 in your bloodThis form helps the body absorb calcium and maintain healthy
bonesThis is the blood circulating form that is and should be
measured by doctors1,25D3 or Calcitriol
A steroid hormone also made from vitamin D3Manufactured in many cells, tissues and organs in the bodyThis form helps the intestine absorb more calcium and
phosphorusSince this form comes from the kidneys, a 1,25D3 test does
not reflect how much vitamin D3 is in other organs and should not be used to measure healthy circulating levels of vitamin D
Vitamin D3: Leads to other forms that help create healthy bones, prevent cancer, and much, much more!
Other Vitamin D termsVitamin D1
Found to be a mixture of compounds rather than a vitamin D product.
A term no longer usedVitamin D2 (ergocalciferol)
Produced by plants and fungi when exposed to sunlight.
Not produced naturally in the human body. It is similar but not identical to vitamin D3Less potent and less effective than Vitamin D3,
yet is still prescribed by many doctors.Vitamin D4 and D5
Derivatives of vitamin D3
What is the role of Vitamin D?The major biological function of Vitamin D
is to maintain normal blood levels of calcium and phosphorous
Healthy levels of Vitamin D in the blood help the body absorb calcium to maintain strong bones Rickets – softening of the bones in children
which can cause skeletal deformities, is due to vitamin D deficiency
Osteomalacia – muscle and bone weakness in adults, is due to vitamin D deficiency
What is the role of Vitamin D?Additional research suggests that healthy
levels of Vitamin D also aid in the treatment or prevention of many other diseasesOsteoperosisCancerDiabetesHypertension (high blood pressure)Several autoimmune diseasesInfluenza
Levels of Vitamin D and how it relates to Vitamin D Deficiency
Level of Vitamin D Deficiency / Sufficiency
< 10 ng/ml Severe deficiency
10 - 20 ng/ml Deficient
20 – 30 ng/ml Insufficient
30 ng/ml and above “Normal”
40 – 70 ng/ml Optimal (at time of writing)
Over 100 ng/ml Overdose
Over 150 ng/ml Toxic

A Worldwide Problem:Children and Vitamin D deficiencyStudies conducted in Main and Mass, found over
half of these groups were deficient in Vitamin D52% of African –American and Hispanic teenagers48% of white pre-adolescent girls
Studies conducted in the winter throughout the US supported these findings of vitamin D deficiency42% of females aged 15-49
Even in sunny parts of the world such as Indian, Turkey and Lebanon, found vitamin D deficiency30-50% of the children had deficient vitamin D
levels (<20 ng/mL)
A Worldwide Problem: Vitamin D DeficiencyPregnant and Nursing MothersIn a study of women giving birth…despite taking
prenatal vitamins with 400 IU of vitamin D..73% of the mothers were severely deficient80% of the babies were severely deficient at birth
A Canadian study found that in the second trimester…Only 11% had adequate levels of vitamin D
Another study in New York showed that…69% of paired infants and mothers were vitamin D
deficientVitamin D penetrates a mother’s milk in correlation
with her own blood levelsTaking only 400 IU/day is not sufficient to raise the D
levelsHowever, 4,000 IU/day can raise the blood levesl of
their babies to > 30 ng/ml
A Worldwide Problem: Vitamin D Deficiency and ObesityVitamin D is fat-soluble and is therefore, stored in fat
cellsObese individuals have more fat cells to collect the
vitamin DAs a result, there is less vitamin D available to the
kidneys and intestines and therefore, less calcium available to maintain strong bones
Correlation between obesity and vitamin D deficiency-related osteomalacia [Michale Holic, MD, PhD]
A study in the UK (2008) found that levels of postmenopausal women were lowest in those with the highest mass index23 ng/ml in the Fall (highest sunshine time at 57 degrees
north latitude)19 ng/ml in the Spring
A worldwide problem: Vitamin D Deficiency in the ElderlyMore than half of Americans > 65 years
are deficient, putting them at risk for more bone fractures50% have < 30 ng/mlAs people age, they lose muscle mass and
strength.This weakening can lead to an increased
risk of fallingBy age 65, 1 in 3 people fall each yearBy age 80, 1 in two people fall each year
A worldwide problem: Vitamin D Deficiency in Other DiseasesSince vitamin D is fat soluble, people who
have illnesses that prevent them from absorbing could be at risk for vitamin D deficiencyCrohn’s diseaseCystic fibrosisThose who have undergone gastric-bypass
surgeryLiver or kidney failure – impairs the ability of
these organs to process vitamin D
Vitamin D and CancerResearches in the US have drawn the following conclusions
about cancer and insufficient levels of Vitamin D60,000 premature deaths in the US from cancer or 10% of total
cancer deaths7,000 premature deaths in Canada
Study in 2007 by the American J. Clinical Nutrition supports these findingsStudied 403 postmenopausal women over a period of four yearsThose taking vitamin D and calcium had a reduced risk of any
kind of cancer by 77% compared to those receiving the placeboRetrospective studies ongoing further support these findings
People living at higher latitudes are at higher risk for developing cancer
Seasonal studies show that people diagnosed with cancer (colon, breast, and prostate) in the summer or the fall had a better chance of survival than those diagnosed with cancer in the winter or spring
Vitamin D has been linked to the risk reduction of 17 different cancer
Breast Uterine
Colon Cervical
Prostate Gall bladder
Bladder Laryngeal
Esophageal Oral
Gastric Pancreatic
Ovarian Non-Hodgkin’s lymphoma
Rectal Hodgkin’s lymphomas
Renal

Vitamin D and Cardiovascular Health Heart Attack
Men deficient in vitamin D (< 15 ng/ml) were 242% more likely to have a heart attack compared to men with 30 ng/ml circulating vitamin D
Men with lower levels (22 – 29 ng/ml) were still at a heightened risk (160%) compared to those with 30 ng/ml circulating levels of vitamin D
High blood pressureMen and women with < 15 ng/ml were three times more likely to
have diagnosis of high blood pressure compared to those with 30 ng/ml
Congestive heart failureVitamin D levels 50% lower than people with healthy heartPatients with the worst cases of congestive heart failure had the
lowest vitamin D levels Peripheral artery disease (reduced blood flow in the legs)
64% more common in people with low levels of vitamin D

Vitamin D and Bone Health55% of all Americans over the age of 50 have either
osteoporosis or low bone mass (osteopenia)Osteoporosis occurs as bones lose minerals and
become weak, brittle, and prone to breaking33% of women between 60-70 years have osteoporosis66% of women of women over 80 have it
Osteomalacia or adult rickets, is clearly associated with vitamin D deficiencyBones do not harden, resulting in softer bones
Vitamin D’s primary role is to ensure that calcium is metabolized in the body and deposited in your bones
Vitamin D deficiency may only allow you to absorb one half to one third of the calcium that you would absorb with healthier vitamin D levels
Vitamin D and Chronic Pain25% of Americans (75 million) suffer with
chronic painThe following types of chronic pain could be
associated with insufficient levels of vitamin DUnexplained muscle, joint, or bone painFibromyalgiaMyalgiaChronic fatigue syndromeVarious studies suggest that 70% of those
with chronic pain have sufficient vitamin D levels < 20 ng/ml
Vitamin D and Autoimmune Diseases23.5 million Americans have autoimmune diseases
75% are women80 – 100 diseases are autoimmune related
Autoimmunity means that the immune system becomes faulty and attacks the body it is meant to protect
The endocrine system (Type 1 or insulin-dependent diabetes)Strongly associated with a vitamin D deficiency in infants
Nervous system (multiple sclerosis)Strongly correlated with latitude (i.e., amount of sunlight):
N Am, Europe and Southern Australia have higher rates than people in Asia, which is closer to the equator
Joints (rheumatoid arthritis)Recent studies suggest there is a correlation with vitamin
D deficiency but studies are in their infancy
Vitamin D and InfluenzaStudies of flu epidemics in the early 1990’s by Dr.
R. Edgar Hope-Simpson, MD suggested that the affects were seasonal due to how much sunshine people receivedLack of sunshine in winter increased likelihood of
contracting the fluResearch has since shown that vitamin D has a
positive impact on the immune systemBoots the macrophages (bacteria-killing white cells)Enhances the body’s natural antibiotic molecules that
exist in the lining of the respiratory tractHigher doses of vitamin D have shown to reduce
the frequency of respiratory infections in children
Vitamin D Deficiency Levels Related to Specific Health Conditions

Rickets and Osteomalacia 15 ng/ml
Suppress parathyroid hormone levels 20-30 ng/ml
Optimize intestinal calcium absorption 34 ng/ml
Improve neuromuscular performance 38 ng/ml
Reduction of incidence of internal cancer
38 ng/ml
50% lower risk of colon cancer 33 ng/ml
50% reduction in breast-cancer incidence

The Challenge: Getting enough Vitamin D3 – our primary source is the sunExposure to just 30 minutes of sunlight can
allow the body to generate 10,000 – 12,000 units of vitamin D3. [Heaney and Holick, et al)
However,…In the summer months, use of sun screens (to
protect against skin cancer) decreases our ability to make vitamin D3
In the winter months, we’re not outside enough to generate this amount of vitamin D3
Our modern indoor lifestyle, compared to even 50 years ago, limits our exposure to sunlight and the opportunity to make more vitamin D3
The Challenge: getting enough vitamin D3 – our secondary source is foodFoods naturally rich in vitamin D (cod liver oil,
salmon, makarel, etc) are not commonly consumed by most of the population and even if consumed, do not contain sufficient amounts
The foods which are commonly consumed (milk, eggs), are low in vitamin D content
Even foods fortified with vitamin D such as found in milk, cereal, and orange juice, do not contain enough vitamin D to maintain healthy levels in the blood
While severe forms of some diseases such as Rickets and Osteomalacia can be cured with foods rich in vitamin D, less severe forms of these diseases often go undetected
The Challenge: Getting enough Vitamin D; Supplements, the third & most practical sourceVitamin D3
Naturally produced by the bodyThe recommended and purist form of vitamin
DConsidered safer than Vitamin D2
Vitamin D2 A synthetic, not naturally produced by the
body50% less potent and effective than Vitamin
D3Still often prescribed by physicians
Vitamin D dosage: Addressing Short vs Long-Latency Deficiency DiseasesShort Latency Deficiency Diseases
Symptoms show rather quicklyExamples: rickets and osteomalacia
Long Latency Deficiency DiseasesSymptoms take many years to manifestExamples: Cancer, Cardiovascular Disease,
Central Nervous System degeneration20% of breast cancer cases in Europe were a
result of vitamin D deficiency [pg 69, Paper published by in 2002 by Dr. Willian B. Grant]
Most national nutritional policies are oriented toward short-latency deficiency
Hence, the current daily recommended dosages are ten times too low!
So how much Vitamin D3 is enough?The current FDA guidelines recommend that
adults get between 400 – 600 IUs as their Recommended Daily Intake (RDI)This amount barely raises blood concentrations of
circulating 25(OH)D (the form of vitamin D measured by doctors)
This amount is also certainly deficient for those that live in the very northern or southern regions of the globe that have limited exposure to the sun
Under pressure from vitamin D specialists, nutritionists, scientists, and clinicians, the FDA plans to increase their RDITheir report with the final RDI amount will not be
available until 2010
So how much Vitamin D3 is enough?Two leading vitamin D specialists, Drs. Heaney
and Holick, recommend the following levels of circulating 25 OH,D:32 – 48 ng/ml (or 80 – 120 nmol/L)
To obtain these levels, various Vitamin D regimens are recommended2,000 – 5,000 units a day indefinitely10,000 units a day for several monthsHigher dosages, of up to 50,000 units for 30 days,
are recommended to target certain illnesses, such as the flu, at a specific point of their cycle
Monitored by a periodic 25 OH,D blood test
Supplements: how much is really absorbed?It is well known that the body only absorbs
about 10% of any supplement taken in pill form [ref]Most of the supplement is lost during digestion
However, supplements taken in oral spray form (and thus not digested), are almost 100% absorbed through the oral tissues [ref]
Therefore, the daily recommended doses for the Vitamin D supplement in these two forms are differentPill form – 50,000 unitsSpray form – 10,000 units
Spray form of Vitamin D3 has other benefitsHealthy levels of circulating 25, OH-D are
reached more quickly with oral spray [ref]Oral spray – within 5 daysPill form – almost two months
This becomes extremely important when treatment needs are more immediate to address diseases
In Summary - Vitamin D is more than just a treatment for stronger bonesGrowing research supports that Vitamin D can
protect us against many diseases:Diminishing muscle strength / weaknessOsteoperosis and OsteomalaciaAutoimmune diseases such as Multiple Sclerosi
(MS) and Rheumatoid Arthritis (RA)Immunity and energy metabolismDiabetesCancer (prostate, breast, colon, etc)Gum diseasesObesityRenal failureInfertilityPregnancy eclampsia
“Vitamin D has an amazing ability to ward off disease…The problem is, the vast majority of us are not
getting nearly enough vitamin D and it is nearly impossible to get a therapeutic dose from diet and sunlight alone. Only 10% of vitamin supplements taken in pill form are absorbed by the body, where as when taken in oral spray form, are almost 100% absorbed.”

How Vitamin D might affect cancerCurrent understanding is that high levels of vitamin D may
enhance the following body processesApoptosis (or programmed cell death)
Cancer cells lose their ability to die off when they become compromised in some way, causing them to grow uncontrollably
Vitamin D makes cells that are turning cancerous die when they are suppose to
Cell differentiation (cells evolve into specialized cell types)Normal cells evolve and stop growing when they reach
maturityCancer cells do not evolve and therefore do not stop growingVitamin D helps make cancer cells evolve and mature into the
cell type they are supposed to becomeCell proliferation (cell growth and division)
Genes that control cell division are affected by vitamin DIf vitamin D levels are low, ability of genes to affect cell
growth are impaired
Source: Lappe…pg 78-80
How vitamin D might affect cancerRegulating cell growth
Vitamin D prevents angiogenesis which is the formation of blood vessels
Cancer cells create new blood vessels so the cancer can grow
Vitamin D impacts the genes that control angiogenesis, blocking cancer cells from creating new blood vessels (so they cannot keep growing)
Reduction of metastasis Metastasis is the ability of cancer cells to enter
the bloodstream and travel to other parts of the bodoy
Animal studies indicate vitamin D may inhibit the ability of cancer cells to spread this way
