NOW Vitamin D-1000 softgels supply recommended levels of this key vitamin in a highly-absorbable liquid softgel form. &ampnbsp;Vitamin D is normally obtained from the diet or produced by the skin from the ultraviolet energy of the sun. &ampnbsp;However, it is not abundant in food. &ampnbsp;As more people avoid sun exposure, Vitamin D supplementation becomes even more necessary to ensure that your body receives an adequate supply.
