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
Space it a couple of hours from SAMe
On the label
As a dietary supplement, take 1 capsule, 1-3 times daily, between meals.
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.
