Hormones are chemical substances synthesized by the body to act as cellular signalers. Hormones’ main function is to work by regulating growth, development, reproduction and the functions of many tissues, as well as the metabolic processes of the organism. It is important to maintain good levels of all hormones, as any change can result in different kinds of dysfunction. Supplements that help regulate hormones work in different ways, which can increase their synthesis and secretion or even intervene in positive and negative feedbacks in the body.
