How to Take It
Best taken in the evening
Contains 5-HTP, so it belongs in the evening. Vitamin B6 is easier on the stomach taken with food.
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
Take 1 capsule daily, preferably on an empty stomach at bedtime. Store in a cool, dry place after opening.
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.
