Overview

? Tryptophan is an essential amino acid that plays a crucial role in human health. It is used by the body to produce serotonin, a neurotransmitter that helps regulate mood, sleep, and appetite. It is also used to create other hormones and proteins important for the body’s normal functioning. Without enough tryptophan, the body cannot produce enough of these important substances, leading to symptoms such as insomnia, depression, and poor appetite. As a dietary supplement, tryptophan can be used to help address these symptoms and improve overall health.
