How to Take It
Best taken in the evening
Contains 5-HTP, so it belongs in the evening. Take it with food — the niacin in it is what makes this kind of product feel nauseating on an empty stomach.
With food
Keep it away from protein-heavy meals
Space it a couple of hours from SAMe
On the label
Adults take 2 capsules once or twice a day, children over 6 years, 1 a day, on an empty stomach, or as your health professional advises. Do not exceed recommended daily intake.
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.
