What It Does

5-HTP 50 mg provides 50 mg of L-5-hydroxytryptophan per capsule to support healthy mood, restful sleep, and balanced appetite.* As a direct precursor to serotonin and melatonin, 5-HTP supports neurotransmitter pathways involved in emotional well-being, circadian rhythm regulation, and satiety.*

How It Works

• L-5-Hydroxytryptophan (50 mg): Sourced from Griffonia simplicifolia seed and tested for purity, this amino acid crosses the blood-brain barrier and is converted to serotonin and melatonin.*[1]
• Mood Support: 5-HTP enhances serotonin activity in brain regions linked to emotion and cognition.* Clinical trials using dosages of 150–400 mg per day support mood.*[5-6]
• Sleep Support: Supports deeper, more restful sleep by supporting melatonin levels via serotonin conversion.* Trials in both children and adults show support of sleep quality and sleep architecture.*[7-8]
• Appetite Regulation: 5-HTP supports satiety by enhancing serotonin signaling in the hypothalamus, leading to reduced carbohydrate cravings and food intake.*[9-11]
• Gut-Brain Axis and Microbiome: Supplementation has been shown to increase serotonin levels and positively impact gut microbiome diversity, supporting the role of serotonin in both mood and digestive health.*[8]
• Pharmacokinetics: With a typical half-life of 2–5 hours, 5-HTP is often taken multiple times daily for sustained support.*[2]
• Purity and Source Assurance: Derived from Griffonia simplicifolia and free from known contaminants associated with improperly produced tryptophan derivatives.* Each lot is rigorously tested for identity, purity, and quality.*

Who It's For

5-HTP 50 mg is ideal for individuals seeking support for mood, sleep quality, or appetite regulation.* It may be particularly helpful during periods of stress.*

Special Features
