D3-2000™ is a natural, soy-free, bioidentical vitamin D supplement. Vitamin D, considered both a hormone and a vitamin, is manufactured in response to skin’s exposure to sunlight and is essential to the body’s absorption of calcium. Natural vitamin D3 (cholecalciferol) is four times more potent than synthetic vitamin D2.* In Latin, calciferol means “calcium carrier.” Additionally, vitamin D has been the subject of numerous studies for its effect on the immune system by promoting phagocytosis and immunomodulatory functions.
