Best taken in the morning

On an empty stomach
Space it a couple of hours from 5-HTP

On the label

Take one capsule daily, or as directed by your healthcare practitioner.

Do not combine with St. John's Wort

Each of these raises serotonin activity on top of St. John's Wort, and together they can trigger serotonin syndrome — agitation, rapid heartbeat, raised blood pressure. Not without medical supervision.

General guidance based on the ingredients, not a substitute for the label or your doctor.
