How to Take It
Best taken in the evening
Contains 5-HTP, so it belongs in the evening. Take it with food — the zinc 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 Iron, Calcium and SAMe
On the label
4 capsules taken 1-2 times per day, morning or early afternoon on an empty stomach, or as recommended by your health care professional.
The label says morning, but the 5-HTP in it makes evening the safer call.
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.
