Immune Supplement MASTER Vitamins
Vitamin D is both a nutrient we eat and a hormone our bodies make. It is a fat-soluble vitamin that has long been known to help the body absorb and retain calcium and phosphorus. For most people, the best way to get enough vitamin D is by taking a supplement because it is hard to eat enough through food. Vitamin D supplements are available in two forms: vitamin D2 (“ergocalciferol” or pre-vitamin D) and vitamin D3 (“cholecalciferol”).Vitamin D production in the skin is the primary natural source of vitamin D.
