What the brand says

Sold as “Meridian Naturals L - Tryptophan 500 mg 120 Kcaps, 12 ounces Bottle”

L-Tryptophan is an essential amino acid found in foods such as dairy products, soy products, meats, poultry, nuts, eggs, seeds, fruit, whole grains, and seafood. An amino acid is a building block for forming muscles and other tissues in your body. It is considered essential meaning that your body cannot manufacture L-Tryptophan on its own. Your brain turns the L-Tryptophan into serotonin, a neurotransmitter that controls mood, hunger, thirst, and sleep.
