The huge variety of diet pill brands and offers at the markets does not make any significant progress in respect to women’s health; furthermore, none is going to deny this fact. The most problematic point for any artificial product, which is introduced at the market, is diet pills side effects. In general, there is no substance that would not produce any side effect on one’s organism; on the other hand, in order to produce diet pills that work, it is necessary to introduce some biologically or chemically active substances in order to make the pills working and affecting this or that side of one’s body metabolism. Moreover, taking account that women’s organism is more complex than men’s and the nature of the processes inside women are much more difficult to qualify, the creation of diet pills for women requires more investments and knowledge because the number of known and potential side effects are higher and they are much riskier in such cases. Some of such pills are designed for combined consumption and some kind of physical activities, which are targeted to normalize one’s body processes and thus return it to natural functioning wherever it is possible. The main problem here lies in the various substances interconnection: even last century it was possible to predict or research effect on one’s body, but now due to the high number of various substances one’s body is consuming with food, medications and environment, it is extremely difficult to foresee the biochemical reactions.
