L-Tryptophan
Essential amino acid and precursor of serotonin and melatonin. May improve sleep, mood, and reduce anxiety. Gentler than 5-HTP.
💡 Absorption: Take with a light carbohydrate (facilitates passage to the brain). Avoid with proteins (they compete). 30-60 min before bed.
⚠️ Caution: DO NOT combine with SSRI antidepressants (risk of serotonin syndrome). Safer than 5-HTP but the same precautions apply.
