Overview
5-HTP is a direct precursor to serotonin and is commonly used to support mood and sleep regulation. It can be effective for short-term mood support, but should be used cautiously due to its strong influence on serotonin pathways. It is often paired carefully with other compounds to avoid overstimulation of serotonin systems.
