5-HTP CR has a delivery system that releases 5-HTP over a period of time. 5-HTP is a plant-derived amino acid that naturally increases the body’s level of serotonin, the chemical messenger that affects emotions, behavior, appetite, and sleep. Today’s stress-filled lifestyles and dietary practices may negatively affect how the body handles serotonin. Regular use of XYMOGEN’s 5-HTP CR may help to support a positive outlook and healthy appetite responses.*
