Our Vitamin D3 softgels supply recommended levels of this key vitamin in a highly absorbable liquid softgel form. Vit D3 is normally obtained for the diet or produced by the skin from the ultraviolet energy of the sun. However, it is not abundant in food. As more people avoid sun exposure, Vit D3 supplementation becomes even more necessary. D3 has been scientifically proven to alleviate depression, reduce osteoporosis and boost immune system.
