About this page: Data is drawn from Nutriofia's structured database of published sources (CoFID, USDA, and published analytical literature). The coverage bar shows what percentage of our 1014 foods have been measured for Tryptophan. This is a research tool — nothing here constitutes medical advice.

About Tryptophan

An essential amino acid and precursor to serotonin and melatonin; also contributes to niacin synthesis.

⚠️ Too little

Deficiency is uncommon; typically reflects inadequate overall protein/energy intake.

🚫 Too much

High-dose supplements may cause side effects and interact with medicines; food sources are generally safe.
