Vitamin D3 60 Capsules
Bone and Immune Health
Sunlight is a source of life on Earth, but we may not be aware of all the ways it benefits us. Our bodies manufacture vitamin D-3 when the skin is exposed to UV radiation from sunlight, but the ability to do so decreases as we age. Vitamin D-3 maintains healthy calcium and phosphorus levels in the body for strong bones, it helps maintain muscle strength in older adults, and it also plays an active role in a healthy immune response. Vitamin D-3 (cholecalciferol) is the optimal form of vitamin D. It is the form of vitamin D that the body manufactures in sunlight, and the form most efficient for the body’s needs.*

If there is one thing to do in order to stave off the Flu (of any type) what would it be? The answer from several doctors is …add Vitamin D3 to your Vitamin Regimen!
The Sunshine Pill. Vitamin D3 is responsible for many functions in the body and one thing is for certain, we are not getting enough. Lifestyle is one reason and Autumn/Winter sun restrictions is another. In early October 2009, I listened to three medical radio shows back to back on local radio. All three shows were about Vitamin D3. While conservative convention says 2,000 IU a day is sufficient, many believe this is off the mark. We suggest 3 tablets of 1,500 IU a day for a healthy adult. This may be the single most effective flu prevention out there. While its true you can get the flu even if you are doing everything possible, we still feel that an ounce of prevention is worth a pound of cure. There is a vast body of science showing the many health benefits of vitamin D. You may be surprised to learn the important role that vitamin D plays in your health. When considering Vitamin D as a supplement, it’s important to know that Vitamin D3 is best absorb by the human body.
Maintains Your Calcium Balance Maintenance of blood calcium levels within a narrow range is vital for normal functioning of the nervous system, as well as for bone growth, and maintenance of bone density. Vitamin D is essential for the efficient utilization of calcium by the body.
Aids Your Cell Differentiation Cellular differentiation results in the specialization of cells for specific functions in your body. In general, differentiation of cells leads to a decrease in proliferation. While cellular proliferation is essential for growth and wound healing, uncontrolled proliferation of cells with certain mutations may lead to diseases like cancer. The active form of vitamin D, inhibits proliferation and stimulates the differentiation of cells.
Boosts Your Immunity Active vitamin D is a potent immune system modulator. There is plenty of scientific evidence that vitamin D has several different effects on immune system function that may enhance your immunity and inhibit the development of autoimmunity.
Blood Pressure Regulation Adequate vitamin D levels may be important for decreasing the risk of high blood pressure. More studies on vitamin D and hypertension are necessary. Vitamin D and Diseases According to the National Institutes of Health, vitamin D may play a role in the following diseases.
Vitamin D and Osteoporosis Osteoporosis is most often associated with inadequate calcium intake. However, a deficiency of vitamin D also contributes to osteoporosis by reducing calcium absorption. While rickets and osteomalacia are extreme examples of vitamin D deficiency, osteopororsis is an example of a long-term effect of vitamin D insufficiency. Adequate storage levels of vitamin D help keep bones strong and may help prevent osteoporosis in older adults, in those who have difficulty walking and exercising, in post-menopausal women, and in individuals on chronic steroid therapy.
Vitamin D deficiency, which is often seen in post-menopausal women and older Americans, has been associated with greater incidence of hip fractures.39-41 In a review of women with osteoporosis hospitalized for hip fractures, 50 percent were found to have signs of vitamin D deficiency. Daily supplementation with 20 800 IU of vitamin D may reduce the risk of osteoporotic fractures in elderly populations with low blood levels of vitamin D. The Decalyos II study examined the effect of combined calcium and vitamin D supplementation in a group of elderly women who were able to walk indoors with a cane or walker. The women were studied for two years, and results suggested that such supplementation could reduce the risk of hip fractures in this population.
Vitamin D and Cancer Laboratory, animal, and some preliminary human studies suggests that vitamin D may be protective against some cancers. Several studies suggest that a higher dietary intake of calcium and vitamin D correlates with lower incidence of cancer. In fact, for over 60 years researchers have observed that greater sun exposure reduces cancer deaths. The inverse relationship between higher vitamin D levels in blood and lower cancer risk in humans is best documented for colon and colorectal cancers. Vitamin D emerged as a protective factor in a study of over 3,000 adults who underwent a colonoscopy to look for polyps or lesions in the colon. There was a significantly lower risk of advanced cancerous lesions among those with the highest vitamin D intake. Additional clinical trials need to be conducted to determine whether vitamin D deficiency increases cancer risk, or if an increased intake of vitamin D is protective against some cancers. Until such trials are conducted, it is premature to conclude you should take vitamin D supplements for cancer prevention.
Vitamin D and Alzheimer’s Disease Alzheimer’s disease is associated with an increased risk of hip fractures because many Alzheimer’s patients are homebound, frequently sunlight deprived, and older. With aging, less vitamin D is converted to its active form. One study of women with Alzheimer’s disease found that decreased bone mineral density was associated with a low intake of vitamin D and inadequate sunlight exposure. More investigation on vitamin D and Alzheimers Disease is necessary.
Other Diseases Vitamin D Deficiency May Affect
Autoimmune Diseases – Diabetes, Multiple Sclerosis and Rheumatoid Arthritis Diabetes mellitus, multiple sclerosis, and rheumatoid arthritis, are each examples of autoimmune disease. Autoimmune diseases occur when the body launches an immune response to its own tissue, rather than a foreign pathogen. Treatment with vitamin D has beneficial effects in animal models of all of the above mentioned diseases. Studies have found that the prevalence of diabetes, multiple sclerosis, and rheumatoid arthritis increases as latitude increases, suggesting that lower exposure to sun light and associated decreases in vitamin D synthesis may play a role in the development of these diseases. The results of several studies also suggest that adequate vitamin D intake may decrease the risk of autoimmune diseases. Evidence from animal models and human studies suggests that maintaining sufficient vitamin D levels may help decrease the risk of several autoimmune diseases, but more studies are needed to draw any solid conclusions. At present, data from controlled clinical trials are too limited to determine whether vitamin D supplementation will be effective in lowering blood pressure or preventing hypertension. Vitamin D Toxicity It is very rare to have a vitamin D overdose. Vitamin D toxicity induces abnormally high serum calcium levels (hypercalcemia), which could result in bone loss, kidney stones, and calcification of organs like the heart and kidneys if untreated over a long period of time. When the Food and Nutrition Board of the Institute of Medicine established the tolerable upper intake level (UL) for vitamin D, published studies that adequately documented the lowest intake levels of vitamin D that induced hypercalcemia were very limited. Because the consequences of hypercalcemia are severe, the Food and Nutrition Board established a very conservative UL of 2,000 IU/day (50 mcg/day) for children and adults. (see table below) Research published since 1997 suggests that the UL for adults is overly conservative and that vitamin D toxicity is very unlikely in healthy people at intake levels lower than 10,000 IU/day.
Vitamin D3 Supplements It is not always practical to get your vitamin D from sunshine, and quite difficult to get adequate amounts from your diet so for many people, a vitamin D supplement is a practical way to ensure adequate levels of this important protector are always available in your bloodstream.
Vitamin D Helps Protect You Against Cancer
Vitamin D is a steroid hormone that influences virtually every cell in your body, and is easily one of nature’s most potent cancer fighters. So I want to stress again that if you are shunning all sun exposure, you are missing out on this natural cancer protection.
Your organs can convert the vitamin D in your bloodstream into calcitriol, which is the hormonal or activated version of vitamin D. Your organs then use it to repair damage, including damage from cancer cells and tumors. Vitamin D’s protective effect against cancer works in multiple ways, including:
- Increasing the self-destruction of mutated cells (which, if allowed to replicate, could lead to cancer)
- Reducing the spread and reproduction of cancer cells
- Causing cells to become differentiated (cancer cells often lack differentiation)
- Reducing the growth of new blood vessels from pre-existing ones, which is a step in the transition of dormant tumors turning cancerous
This applies not only to skin cancer but other types of cancer as well. Theories linking vitamin D to certain cancers 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, according to epidemiologist Cedric Garland, DrPH, professor of family and preventive medicine at the UC San Diego School of Medicine.
Here are just a few highlights into some of the most noteworthy findings:
- Some 600,000 cases of breast and colorectal cancers could be prevented each year if vitamin D levels among populations worldwide were increased, according to .previous research by Dr. Garland and colleagues
- 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.
- A large-scale, randomized, placebo-controlled study on vitamin D and cancer showed that vitamin D can cut overall cancer risk by as much as 60 percent. This was such groundbreaking news that the Canadian Cancer Society has actually begun endorsing the vitamin as a cancer-prevention therapy.
- Light-skinned women who had high amounts of long-term sun exposure had half the risk of developing advanced breast cancer (cancer that spreads beyond your breast) as women with lower amounts of regular sun exposure, according to a study in the American Journal of Epidemiology.
- A study by Dr. William Grant, Ph.D., internationally recognized research scientist and vitamin D expert, found that about 30 percent of cancer deaths — which amounts to 2 million worldwide and 200,000 in the United States — could be prevented each year with higher levels of vitamin D.
My question is about vitamin D and milk. Is there a difference between the vitamin D in milk and vitamin D3 in supplement form? Is it possible to “overdose” on vitamin D if someone takes a supplement of 1000 IUs a day and drinks a lot of milk? I realize that milk has its own issues (pasteurization, hormones, etc) but strictly speaking vitamin D, can you get what you need from drinking several glasses a day? How much vitamin D (or D3) would it take to “overdose” on it?
Dr Mark Hyman’s Ans: It is a mistaken notion that vitamin D is naturally found in milk. Vitamin D was added to milk to prevent rickets during the early part of the 20th century. There are only 125 units on average per glass of milk. Our current understanding of vitamin D needs is different than it was in years past. Current needs for a vitamin D replete or nourished person is 1000 to 2000 units for maintenance a day. However, if you are vitamin D deficient you may need up to 10,000 units a day for many months. Dr. Robert Heaney and Michael Holick have studied this extensively and found no toxicity using 10,000 units a day for 20 weeks in healthy young males. Personally I have used 5,000 to10,000 units a day in my practice for many years for three to six months with not one case of vitamin D toxicity. And in factI think you would be hard pressed to find one physician who has ever seen a case of vitamin D toxicity despite being brainwashed about the dangers of this in medical school.
I think that in order to get adequate amounts of vitamin D you would need to drink 20 glasses of milk a day, which is I think concerning for many reasons. I believe that milk in its current form, which is homogenized, pasteurized, raised from corn fed animals and hybridized GMO strains of grain and processed with antibiotics and hormones is not the traditional dairy product eaten over the centuries. Dairy has many harmful effects including increase in allergy, type 1 diabetes, intestinal distress, chronic sinus infections, ear infections, cancer as well as being the leading cause of iron deficiency anemia and constipation in children.
The USDA food pyramid guidelines for drinking milk are not based current science. This is well documented by Dr. Walter Willett. Therefore I do not think that people should consider milk their source of vitamin D. I do believe that there are good dietary sources including mackerel and herring. However, sun exposure to large surface area skin such as chest, arms, back and legs for 15 minutes a day according to Michael Holick is a safe, effective way to get vitamin D production, however people who live in northern climates cannot generally do this and therefore I recommend that all people be on at least 2000 units of vitamin D3 a day.
