Amino acids

L-tryptophan is an amino acid that plays a role in protein synthesis and serves as a precursor for the production of serotonin, a crucial neurotransmitter in the brain. This compound is typically obtained through the consumption of food sources such as meat, poultry, fish, eggs, and other protein-rich foods. L-tryptophan is also available as a dietary supplement and may be used for managing sleep-related issues and improving mood.
