5-HTP is the precursor to serotonin, a mood and appetite regulating neurotransmitter produced within the body. It has been combined with Vitamin C and Vitamin B-6, an important cofactor in the conversion to serotonin. We use a natural extract that is buffered to minimize any potential gastric discomfort.
