Bluebonnet's 5-HTP Capsules are formulated with 5-hydroxytryptophan that is extracted from the seed of African plant Griffonia simplicifolia. 5-HTP is the direct metabolic precursor of serotonin and is important for the production of melatonin; therefore, it has been shown in research to help control appetite, support a positive mood as well as promote calm/relaxation and for occasional sleeplessness. Available in easy-to- swallow vegetable capsules for maximum assimilation and absorption.
