How to Take It
Best taken in the evening
Calming herb — used 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
Tryptophan 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 Iron, Calcium and SAMe
On the label
Take 3 capsules as a daily serving, ideally 30-60 minutes before sleep
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.
