Vitamins, a huge industry, Americans spend nearly 2 billion dollars a year on vitamin supplements.
While they contain no calories and can not provide energy, they are required for the release of energy in the body and for the regulation of growth and development, metabolism, and other body processes.
Two types of vitamins:
Fat soluble vitamins(A, D, E, and K) are absorbed and stored in fat tissue. These vitamins are essential for healthy skin, bones, and blood. Excess amounts of these are not excreted and can accumulate and become toxic. Too much vitamin A and D can lead to damage to organs, and other tissues.
Water soluble vitamins(B, C, biotin, folacin, pantothenic acid) are absorbed in the body's water and excreted in urine if taken in excess. These nutrients are essential for energy production, blood cell formation, and proper functioning of the nervous system. There are many people who take mega doses of these, however it can be harmful.
