Tryptophan for Sleep and Mood: What the Evidence Shows
Tryptophan is an essential amino acid that the body converts to serotonin and melatonin; it may support sleep and mood when intake or status is low. As a nutritionist and yoga-oriented guide, I recommend food first: turkey, chicken, eggs, dairy, nuts, and seeds. Supplements can fill gaps but do not replace sleep hygiene or treatment for mood disorders.
Typical supplemental doses in studies range from 500 mg to 2 g, often taken before bed. Evidence is mixed; effects are modest and individual. Compare sleep support and amino acids from trusted brands.
How Tryptophan May Support Sleep and Mood
Tryptophan crosses the blood-brain barrier and is used to make serotonin; serotonin is converted to melatonin at night. Adequate intake supports this pathway. It does not replace treatment for insomnia or depression—consult a provider if symptoms persist.
Practical Tips and Safety
Take tryptophan on an empty stomach or with light carbs to reduce competition from other amino acids. Do not combine with MAOIs or serotonin drugs without medical advice. Sleep supplements on iHerb include tryptophan and related formulas. Pair with a consistent sleep schedule for best results.
