They contribute to good health by regulating the metabolism and assisting the biochemical processes that release energy from digested food. Some vitamins are water soluble and some are fat soluble. Fat-soluble vitamins, including vitamins A, D, E and K can be stored for longer periods of time in the body's fatty tissue and the liver. When nutrients are taken in supplementation form, they function best when taken together in particular combinations. Some nutrients are so closely interrelated that their effectiveness in the body is markedly improved when they are taken together with other nutrients.
Minerals are especially important in aiding effectiveness of specific vitamins.
Bulk minerals, including calcium, magnesium, sodium, potassium and phosphorus, are needed for the proper composition of body fluids, the formation of blood and bone, and the maintenance of healthy muscle and nerve functions. Trace minerals, including zinc, iron, copper, manganese, chromium, selenium and iodine, are important in the production of hormones. Although only minute quantities of trace minerals are needed, they are important for good health. A vitamin and mineral supplement specially formulated in an herbal base increases its potency and synergistic value, meaning that vitamins, minerals, trace minerals and herbs are more effective when used together than when used separately. These synergistic supplements have been designed to support the overall function of one or more body systems.
