Vitamin D (ergocalciferol-D2, cholecalciferol-D3, alfacalcidol) is a fat-soluble vitamin that helps your body absorb calcium and phosphorus. Having the right amount of vitamin D, calcium, and phosphorus is important for building and keeping strong bones.
Are you deficient in Vitamin D3? With all the medical advances in the 20 th century, Vitamin D3 deficiency is still an epidemic. Fifteen to twenty minutes of sunshine each day, in the nude, helps your body manufacture about 10,000 to 15,000 iuâs of vitamin D3 per day. The problem is that most people avoid the sun these days due to fears of skin cancer. Just think about plants and what happens to them when they avoid the sun. They wither & die.
