KNOWING YOUR VITAMINS: IMPORTANCE OF VITAMIN D & SOURCES

We all probably know that vitamin D can be obtained from sunlight, but what are the benefits of Vitamin D to the body and what other sources can it be derived from? The term "vitamin D" refers to several different forms of this vitamin. Two forms are important in humans: vitamin D2, which is made by plants, and vitamin D3, which is made by human skin when exposed to sunlight. Foods may be fortified with vitamin D2 or D3. The major role of vitamin D is to maintain normal blood levels of calcium and phosphorus. Vitamin D helps the body absorb calcium, which forms and maintains strong bones. It is used alone or together with calcium to improve bone health and decrease fractures. Vitamin D may also protect against osteoporosis, high blood pressure, cancer, and other diseases.
