Microcrystalline CelluloseBinder

Plant-derived cellulose used as a binder and filler in supplements

Capsule ShellCapsule

Generic capsule shell where the label does not specify the material. Common materials are hypromellose (HPMC) for vegetarian capsules and gelatin for traditional capsules — both are GRAS-listed and safe. Fish gelatin and pullulan variants also exist.

How to Take It

Check the label before you take this

This product combines a stimulant with a sleep-supporting ingredient, so there's no single good time to take it. Follow the label and keep it well away from bedtime.

With food

5-HTP does better on an empty stomach, but something else in this bottle needs food. Taking the whole product with a meal is the better trade — an upset stomach is why most people stop.

Keep it away from protein-heavy meals
Split into 3 doses across the day

On the label

Take 1 capsule 3 times a day, or as directed by your healthcare professional.

Do not combine with Tryptophan

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.
