Buying Guide

Check the 5‑HTP dose per serving

Higher doses (e.g., 100–200 mg) can be more effective for some users but start low and consult a clinician for personalized recommendations

Prefer time‑release for sustained effect

Time‑release tablets can provide steadier levels overnight compared with immediate‑release capsules for some sleepers

Verify purity and allergen info

Look for vegan, non‑GMO, and gluten‑free labels or third‑party testing to reduce risk of contaminants and allergens

Consider capsule count and value

Compare total milligrams per bottle and capsule count to estimate cost per dose and supply duration

Watch for interactions and contraindications

5‑HTP can interact with antidepressants and other serotonergic agents—speak to a healthcare provider if you take prescription medications
