Description
NOW® Vitamin D-3 softgels provide this key vitamin in a highly absorbable liquid softgel form.
Vitamin D is normally obtained from the diet or produced by the skin from the sun's ultraviolet energy. However, it is not abundant in food.
As more people avoid sun exposure, Vitamin D supplementation becomes even more necessary to ensure your body receives an adequate supply.
Vitamin D is completely different from most vitamins. In fact, it is a steroid hormone produced from cholesterol when the skin is exposed to the sun. For this reason, vitamin D is often called the "Sunshine Vitamin."
However, sun exposure rarely provides the necessary amount of vitamin D, so it is necessary to obtain it through food or supplements.
Vitamin D is a fat-soluble vitamin, meaning it dissolves in fats and oils and can be stored in the body for a long time.
There are several types of vitamin D, but the two most important forms are: D-3 (Cholecalciferol), found in some animal foods such as fatty fish and egg yolk; and D-2 (Ergocalciferol), found in plant-based foods such as mushrooms and yeasts. Of the two vitamins, D-3 is the most active and effective form in increasing blood vitamin D levels.
Cholecalciferol is transformed by the action of sunlight from Pro-vitamin D-3 (7-dehydrocholesterol) found in human skin. Both D-2 and D-3 forms are hydroxylated in the liver and kidneys to 25-hydroxycholecalciferol and subsequently to the biologically active form, 1,25-dihydroxycholecalciferol (Calcitriol), which acts as a hormone in regulating calcium absorption in the small intestine and regulating calcium levels in bone and kidney tissues.
Vitamin D is attributed with the functions of structuring and maintaining bone tissue and balancing calcium and phosphorus levels in the body (homeostasis). In addition, studies show the involvement of this vitamin in other vital processes, such as cell reproduction, hormonal segregation, and action in the Immune System.
