The following factors that increase the body's need for vitamins are stress caused by the accelerated pace of life, alcohol, nicotine, caffeine, various preservatives. A perfect example: one cigarette can depreciate 100 mg of vitamin C in our body.
Vitamins are necessary for the development of the human body, for its life, for good overall physical shape. Some of them regulate chemical processes, while others are components of enzymes needed for metabolism of cells, some have a direct effect on the organism. Strengthening the functioning of muscles, increased intake of proteins and saccharides significantly increase the daily requirement of these substances - in such cases, we are always dependent on dietary supplements.
Because some vitamins are involved in many physiological processes, their increased intake at the same time increases the need for other vitamins. It is therefore advisable to give priority to integrated products. Studies have shown that the ratio of simultaneously taking vitamins is very important (for example, vitamins B ratio is 1:1).
In addition to vitamins, for a healthy working, our body also needs minerals, which can come only with food. Therefore, additional intake of vitamins should also take minerals in proper proportion.
From this perspective, the most suitable are complex products, which contain minerals in an optimal ratio of vitamins, if possible, in chelate form. It fact, in that form our bodies can best use these substances.
For many people, chelates are not enough effectively formed in the body, so their bodies can not take mineral substances completely. For example, the body can absorb only 2-10% iron obtained in an inorganic form, and half of this amount derived from the body with fluids. Mineral substances, introduced in the form of amino acid chelates, digested in 3-10 times more effective than chemical substances in the other form.
A huge forward step in the production of water soluble vitamins was the development of drugs with the so-called prolonged action (Delayed Release). Useful substances are introduced into the carrier environment, it allows them to assimilate gradually, over 8-12 hours, which ensures a constant proper level of vitamins in the blood during the day. No Delayed Release preparations digested faster, but the amount of substances which the body can not immediately use, after 2-3 hours excreted in the urine.
Another advantage of complex products is that they contain a lipotropic substances that burn fat (choline, inositol) and prevent the deposition of fat in the liver. They increase production of lecithin in the liver and retain the existing cholesterol dissolved and prevent the dangerous accumulation in the blood.
Modern multivitamins also contain the natural antioxidant complexes which protect the vitamins from destruction by free radicals. At the same time, these complexes are also an additional source of antioxidants for our body. The most effective natural antioxidants is bioflavonoids and polyphenols obtained from fresh plant material (citrus complex, hesperidin complex and others).
