Vitamin D3 5000 provides optimal vitamin D support and aids the immune system and bone health. Vitamin D, considered both a hormone and a vitamin, is manufactured in response to the 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.

Evidence suggests that taking vitamin D doses above the Recommended Dietary Allowance (RDA) may be beneficial. Numerous studies reveal Vitamin D's ability to enable immune functions and phagocytosis, a process for removing undesired substances at the cellular level.
