Griffonia seed contains naturally high levels of 5-htp (5-hydroxytryptophan) which is an amino acid our body naturally produces from the essential amino acid L-tryptophan. 5-htp is believed to help increase natural levels of serotonin (happy hormone), which may help reduce insomnia, relieve mild anxiety or depression and reduce cravings. Serotonin helps increase melotonin at night which may lead to better quality sleep.
