5-HTP for Sleep & Mood: What Science Says

What Is 5-HTP?

5-HTP (5-hydroxytryptophan) is the direct precursor to serotonin. When you take 5-HTP, your body converts it to serotonin — a neurotransmitter that regulates mood, emotional processing, and sleep cycles. Unlike melatonin, 5-HTP works at the neurochemical level to support natural sleep-wake patterns from the ground up.

How 5-HTP Works for Sleep

By raising serotonin levels, 5-HTP stabilises mood before bed, reduces anxiety that disrupts sleep, and helps regulate melatonin production naturally. It also increases REM sleep for better emotional recovery and reduces nighttime awakenings.

5-HTP Dosage for Sleep

Recommended: 50–100mg, 30–60 minutes before bed. Daily use for 2–4 weeks for full effect. Do not exceed 100mg without medical supervision.

Important: 5-HTP + SSRI Warning

Do NOT combine 5-HTP with SSRIs or SNRIs (Zoloft, Lexapro, Paxil, etc.) without doctor approval. This combination can cause serotonin syndrome — a potentially serious medical condition. Always consult your doctor if you're on any prescription medication.
