5-HTP
L-5 hydroxytryptophan, commonly known as 5-HTP, is a compound produced in the body from the essential amino acid tryptophan. After tryptophan is converted into 5-HTP, it can change into serotonin, aka the happy chemical. Serotonin plays an essential role in depression, anxiety, sleep disorders, weight gain, and other conditions. Therefore, increasing your body’s production of serotonin may have various benefits. Serotonin-producing 5-HTP supplements have been increasing in popularity for this reason.
