Vitamin D is a fat soluble vitamin that is made in your body after exposure to ultraviolet (UV) rays from the sun. Scientists have found that Vitamin D has biological actions in almost every cell and tissue in the human body.  What is troublesome is that vitamin D deficiency is now recognized as a pandemic, affecting 30-50% of the population.1 The amount of vitamin D contained in most multivitamins (400 IU) is simply not enough to fuel all of vitamin D’s vital processes in the body.

Research suggests that vitamin D is important to maintain a healthy immune system, regulate cell growth, and prevent osteoporosis, cardiovascular disease, and cancer. Vitamin D has been shown to protect against the development of autoimmune diseases such as inflammatory bowel disease, multiple sclerosis and rheumatoid arthritis.1-2

Food sources of vitamin D are scarce – exposure to sunlight provides most humans with their vitamin D requirement. The further you live from the equator, the longer exposure you need to the sun in order to generate vitamin D. Season, time of day, cloud cover, smog, and sunscreen affect UV ray exposure and vitamin D synthesis. For example, sunlight exposure from November through February in Boston is insufficient to produce significant vitamin D synthesis in the skin. Melanin is the pigment that gives skin its color. The high melanin content in darker skin reduces the skin’s ability to produce vitamin D from sunlight. It is very important for African Americans and other populations with dark-pigmented skin to consume recommended amounts of vitamin D. Some studies suggest that older adults, especially women, in these groups are at extremely high risk of vitamin D deficiency. There is also considerable evidence to suggest that the epidemic vitamin D deficiency in black men contributes to their high prevalence of prostate cancer.

Vitamin D and Bone Health

Vitamin D sends signals to the intestines to increase the absorption of calcium and phosphorus. By promoting calcium absorption, vitamin D helps to form and maintain strong bones. Vitamin D also works in concert with a number of other vitamins, minerals, and hormones to promote bone mineralization.  Recent medical studies document that vitamin D is more effective than calcium for protecting and building bone. In fact, too much calcium can interfere with the conversion of vitamin D into its biologically active form.3 Therefore, high dose calcium, (especially without a corresponding increase in vitamin D) consumed by so many women, is not the most effective way to increase bone density and may even increase cancer risk as a result of lower vitamin D function. The modern world has an epidemic of vitamin D deficiency and most often a multivitamin containing the RDA for D is simply insufficient to bring blood levels up to the ideal range, especially as we age.

Vitamin D and Cancer
Vitamin D regulates several genes and cellular processes related to cancer progression.  Epidemiologic evidence indicates that vitamin D is protective against several common cancers including cancers of the breast, prostate, pancreas, lung, colon, and endometrium.4


  • Vitamin D2 (ergocalciferol) a fat–soluble vitamin which stimulates the intestines to increase absorption of calcium and phosphorus.
  • Balanced calcium and magnesium for optimal absorption.
  • Necessary for bone–making and bone–maintenance.
  • Added silica, a trace mineral also a major constituent of collagen.


Osteo–Sun vegan formulation is a nutritional supplement designed by Dr. Fuhrman, not only for protection and therapy for osteoporosis, but also for both men and women who desire optimal health. It has been specifically formulated to be higher in vitamin D and lower in calcium and magnesium compared to most other supplements designed for bone health to meet the needs of individuals who work indoors and are not exposed to adequate sunlight to produce optimal levels of vitamin D. Silica has been added to further promote bone mineral density and stronger hair and nails.5

Dr. Fuhrman’s Osteo–Sun vegan formulation gives you the extra vitamin D you need, silica for stronger bones, hair and nails, and just the right dose of calcium and magnesium to bring your intake to the best level to maximize bone health.

Dr. Fuhrman’s Osteo–Sun vegan formulation is designed with each capsule supplying 600 IUs of vitamin D2 so that two to six capsules per day can be utilized depending on each person’s individual needs. Osteo-Sun vegan formulation utilizes vitamin D2 (ergocalciferol), a form of the vitamin which is obtained . Some forms of Vitamin D are not vegan. The most common form found in supplements is cholecalciferol, or Vitamin D3, which is derived from sheeps’ wool. The higher levels of vitamin D2 used in Osteo-sun vegan are sufficient to adjust for its lower vitamin activity.
