5 Hydroxytryptophan (5-HTP) has several functions and health benefits. Hydroxytryptophan (5HTP) is a naturally occurring amino acid, a precursor to the neurotransmitter serotonin and an intermediate in tryptophan metabolism. Due to its connections with serotonin, hydroxytryptophan is also indirectly involved with mood enhancement and the regulation of sleep patterns.

5-HTP is found in minute amounts in certain foods like cheese and the white meat of poultry. Solgar 5-HTP vegetable capsules is one of Solgar's high quality amino acids supplement products. This unique Solgar 5 Hydroxytryptophan (5-HTP) formula also includes B vitamins to promote nervous system health and the calming herb valerian.
