Griffonia Seed P.E.
5-Hydroxytryptophan is the precursor substance of serotonin in human body, which can help the human body to balance this hormone and thus control human mood, improve sleep quality, and can effectively control appetite, increase the sensitivity of the satiety centre, and in the dietary control of the weight loss process, reduce the feeling of hunger, so that the process of weight loss is more relaxed and easy to reach.
5-Hydroxytryptophan (5-HTP) is an intermediate in the biosynthesis of serotonin from the essential amino acid L-tryptophan (LT). It readily crosses the blood-brain barrier and effectively increases serotonin synthesis in the central nervous system (CNS). 5-HTP administration has been shown to be effective in the treatment of a wide range of conditions, including depression, fibromyalgia, binge eating-induced obesity, chronic headaches, and insomnia. Clinical evidence suggests that 5-Hydroxytryptophan provides better relief from depression than placebo.
