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.” Strong evidence suggests that vitamin D intakes well above current recommendations are beneficial, and when combined with calcium, have a significant impact on overall bone health.* Additionally, vitamin D has been the subject of numerous studies for its effect on the immune system by promoting phagocytosis and immunomodulatory functions.*
