Healthwise L-Tryptophan
HealthWise® L-Tryptophan is a 100% pure, pharmaceutical-grade essential amino acid. Tryptophan is found in all animal proteins and may be lacking in a vegan diet. It is an indirect precursor to serotonin, a neurotransmitter used by the body to help regulate mood. L-Tryptophan is also a precursor for vitamin B3 in the form of nicotinamide adenine dinucleotide (NAD), although only a small proportion of tryptophan in the body is converted to NAD.
