Amino Acids



Tryptophan is an amino acid that the body uses to produce serotonin, a neurotransmitter that helps regulate mood, sleep, and appetite. Foods rich in tryptophan include meat, fish, eggs, dairy products, nuts, seeds, and bananas. Since L-tryptophan can help improve sleep as a precursor to melatonin, taking tryptophan supplements can help increase serotonin levels in the brain and thus improve sleep quality. In addition, it also influences all the proper functioning of the brain.
