Vitamin D plays a major role in bone health, joint health, immune health, mood health and cardiovascular health. The two most important forms of vitamin D are cholecalciferol (D3), which is derived from our own cholesterol and ergocalciferol (D2), a plant analogue derived from the diet. The cholecalciferol supplied by the Life Extension 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.
Recent research points to the deficiencies of this vitamin in the general population, its positive benefits against cardiovascular disease, cell mutation, joint and bone health, anti-ageing properties and skin health. In fact, even those who live in areas of sun exposure have been found to have deficiencies of Vitamin D3!
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.
One daily preferably with a low fibre meal.
