How to Take It
Best taken in the evening
Take in the evening. Amino acids compete for the same transport into the brain, so a protein-heavy meal blunts it.
On an empty stomach
Keep it away from protein-heavy meals
Space it a couple of hours from Iron, Calcium and SAMe
On the label
As a dietary supplement, take two capsules per day 30 minutes before bedtime with water.
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.

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.
