L-5 HTP (L-5 hydroxytryptophan)

(Griffonia simplicifolia seed extract)

What It Is

L-5-Hydroxytryptophan (L-5-HTP) is a naturally occurring compound that the body produces from the amino acid tryptophan. It serves as a direct precursor to serotonin, a neurotransmitter that influences mood, sleep, and appetite. While not found in food, L-5- HTP is extracted from the seeds of the Griffonia simplicifolia plant, a shrub native to West Africa long used in traditional medicine.

Take L-5-Hydroxytryptophan as directed on the product label. It can be taken once or twice a day to support mood and sleep. Many people prefer taking it in the evening because it can promote relaxation and restful sleep. For the best results, use it consistently and give your body a few weeks to adjust.

Dosage & Safety

Always consult your healthcare provider before using L-5-HTP, especially if you are pregnant, nursing, or taking medications that affect mood or serotonin.
