On the label

Suggested Usage: As a dietary supplement, adults take 1 capsule, 1-2 times daily between meals or as directed by your health professional.

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.

This is not medical advice. Consult a healthcare provider before making changes to your supplement routine.

The score analyzes what's on the label: ingredient doses vs. studied ranges, chemical forms, evidence levels, and known interactions. It does not verify label accuracy or test for contaminants — for that, look for third-party certifications like USP or NSF.
