What it does: L-Tryptophan is converted in the body into serotonin, a neurotransmitter connected with mood balance and stress response, and then into melatonin, a hormone that regulates the sleep-wake cycle.
How it is used: People use L-tryptophan supplements to support sleep quality, enhance mood, encourage relaxation, and help manage mild stress.
Natural sources and supplement forms: L-Tryptophan is naturally present in foods such as turkey, chicken, dairy products, eggs, nuts, and seeds. Supplemental forms typically use highly purified L-tryptophan produced via fermentation, available in capsules or powders.
Why it appears in supplement formulas: Its connection to serotonin and melatonin production makes L-tryptophan a popular ingredient in sleep, stress relief, and mood balance supplements.
What to know before use: Because it can raise serotonin levels, consult a healthcare professional before use if you take antidepressants or medications that modify serotonin activity.
