Natrol: Vitamin D3 10,000 Iu, 60 Tablets

The single most important nutrient recommended for supplementation! Vitamin D is usually obtained through diet or produced by the skin from the ultraviolet energy of the sun. Poor diet and lack of sun exposure can result in inadequate levels of Vitamin D for optimal health. Additionally, there are very few food sources that contain Vitamin D making it even harder to obtain adequate amounts of Vitamin D needed for superior health. Researchers now know that vitamin D plays a much larger role in promoting health than simply helping build strong bones. Vitamin D helps regulate healthy cell growth, supports immunity, heart health, breast health, colon and prostate health, normal inflammatory response and healthy aging. Research over the last decade suggests that vitamin D may be the single most important nutrient recommended for supplementation.
