the synthesis of melatonin and serotonin, a hormone and a
neurotransmitter involved with mood and stress response. It
helps support relaxation, restful sleep, and a positive outlook.
This tryptophan tablet includes vitamin B-6, which is required
to convert tryptophan to serotonin. If needed, L-tryptophan is
converted to niacin in the body, an important B vitamin. Source
