Vitamin D is necessary for utilization of calcium and phosphorus and in many ways acts as a hormone.78-80 The two most important forms of vitamin D are cholecalciferol (D3), which is derived from our own cholesterol, a plant analogue derived from the diet. The cholecalciferol supplied by the Life Extension Buyers Club is synthetic, but its form is identical to that which is derived from cholesterol and synthesized by sunlight on the skin. Cholecalciferol Vitamin D is essential for bone growth and maintenance of bone density.81-84*
A dietary deficiency of vitamin D inhibits the production of the protein that binds calcium in the intestines, so that calcium cannot be absorbed, even if there is adequate intake. Deficiencies of vitamin D are often found in the elderly and in women who have low intake of milk and receive inadequate exposure to sunlight. Vitamin D is potent in minute quantities, one microgram of cholecalciferol has 40 IU of vitamin D activity.80,85,86
