5-HTP supplements improved sleep quality and managed gut microbiome composition in older adults in Singapore, per a 12-week NUS clinical trial.
5-Hydroxytryptophan (5-HTP) supplements improved sleep quality and managed gut microbiome composition in older adults in Singapore, particularly those with poor sleep patterns, according to a 12-week clinical trial by National University of Singapore (NUS) researchers. As a naturally occurring amino acid, 5-HTP converts into serotonin, a chemical that regulates the sleep-wake cycle. Findings suggest that supplementation may offer a safer alternative to pharmaceutical sleep aids, with potential for improved gut health linked to enhanced sleep quality.
