How Does Vitamin D3 Work?

Keep Your Bones Strong

Vitamin D is available in foods, supplements, and sunlight. Once absorbed, vitamin D undergoes two hydroxylations, one in the liver and one in the kidney, to become active. Vitamin D is critical to maintaining bone density. When blood calcium levels fall, calcium will be pulled from the bone to compensate, decreasing bone density. Vitamin D binds to receptors on responsive genes and stimulates the production of proteins. The parathyroid hormone controls the production of active D3 (cholecalciferol).
