General Statements: All Other Content
5-HTP (L-5-Hydroxytryptophan) is an intermediate in the natural conversion of the essential amino acid tryptophan to serotonin, a brain chemical associated with positive mood and well-being. Preclinical studies show that 5-HTP may help support healthy levels of serotonin in the body. In addition to a balanced mood, serotonin may also support melatonin production and a healthy sleep cycle.
Brand IP Statement(s) re: (c), (TM), (SM)
Serene Science 5-HTP is derived from the seeds of the African plant Griffonia simplicifolia.
