Formula re: Contains
L-Tryptophan is an essential amino acid that the body requires to synthesize proteins and specialized molecules. It is critical for the production of serotonin and melatonin hormones that support positive mood, relaxation, healthy sleep patterns and stress relief. L-Tryptophan also helps support immune functions, as it is the body's precursor to the kyunurnines which regulate immunity. If needed, L-Tryptophan converts to niacin in the body, which supports circulation, healthy nervous system, metabolism of foods, and production of hydrochloric acid for the digestive system.
