Hydroxytryptophan (5-HTP (5-hydroxytryptophan) — Uses, Dosage, Side Effects & Safety

Drug class: Amino acid supplement; Serotonin precursor

Overview

Hydroxytryptophan (5-HTP) is a naturally occurring amino acid and chemical precursor to serotonin, a neurotransmitter that helps regulate mood, sleep, and appetite. It is commonly used as a dietary supplement to support mental well-being, improve sleep, and manage symptoms of mild depression and anxiety. 5-HTP works by increasing serotonin levels in the brain, which may help improve mood, promote relaxation, and support healthy sleep cycles. Some people also use it for migraine prevention and to help with weight management. Key points: 5-HTP is not approved as a prescription medication in most countries but is widely available as an over-the-counter supplement. It should be used with caution, especially if you are taking other medications that affect serotonin levels.
