Vitamin D 5000

Description

Vitamin D is a hormone-like substance that is produced in the skin during exposure to sunlight. Vitamin D deficiency is common and it is estimated that over one billion people in the world are severely deficient. The fear of skin cancer has stopped many individuals from obtaining beneficial amounts of sunlight. The skin uses the energy of UVB to convert 7-dehydrocholesterol into Vitamin D3. Even individuals, who venture out into the sun often and use sunscreen, may be deficient in Vitamin D3. Furthermore, as we age, we are less equipped to produce sufficient quantities of this vital nutrient. One study found that age-related declines in kidney function may require older people to ingest more Vitamin D3 to maintain the same blood levels as younger people. Vitamin D deficiency causes osteoporosis and increases the risk of autoimmune disease.
