Vitamin D3 25mcg (1,000 IU). 120 Capsules.
 
Vitamin D3 capsules supply a high-potency amount of natural vitamin D, called D3. This fat soluble vitamin occurs naturally in only a few foods, thus is often fortified in milk and other products. Vitamin D can also be formed in the body upon adequate exposure of the skin to sunlight. Its major biological function is to maintain normal blood levels of calcium and phosphorus to form and maintain strong bones. Vitamin D also works with a number of other vitamins, minerals and hormones to promote bone mineralization, glucose metabolism, neuromuscular function, and overall health.
