Tryptophan

As a building block for serotonin and melatonin, tryptophan plays an important role in mood balance, stress management, and sleep quality.

What is tryptophan?

L-tryptophan, often simply called tryptophan, is an essential amino acid that the body cannot produce on its own and must be obtained from food or supplements.

It serves as a precursor to serotonin, a neurotransmitter. Serotonin is found throughout the body, particularly in the brain and digestive tract, where it supports communication between nerve cells and influences mood, appetite, and sleep patterns.

Tryptophan is also converted into melatonin, the hormone that helps regulate the sleep-wake cycle.

Tryptophan supplement benefits

Because of its role in both serotonin and melatonin production, tryptophan is commonly used to support restful sleep, a balanced mood, relaxation, and a healthy stress response.
