Tryptophan is an essential amino acid (EAA) which needs to be sourced from diet as it’s not produced by the body. EAAs are considered to be the most important for muscle development and recovery.

This particular amino acid is the precursor to the neurotransmitter serotonin and the hormone melatonin and helps the body to produce them. Supplementing with tryptophan may help you achieve a deeper more restful sleep and can promote relaxation and improve mood.
