How do vitamins and minerals work?
Vitamins and minerals play an essential role in the body’s normal metabolism, growth, and development. They do this by helping the body to perform various tasks. For example, while a vitamin is not a source of energy in and of itself, it can provide the key the body needs to unlock energy stored in food. Some vitamins and minerals work together–such as the mineral zinc and vitamin A. Zinc enables the body to use vitamin A to promote good vision. Deficiencies in vitamin A may lead to night blindness, a condition in which the eyes have difficulty adjusting to darkness. Zinc supplementation, therefore, may prevent this condition by keeping vitamin A functioning normally. Supplementation alone, however, is not the answer to long-term good health. Combining a healthful diet with a regular exercise program and a positive mental attitude has been shown, time and again, to be the best bet for a healthy lifestyle.
