How to Take It
Best taken in the evening
Take 30–60 minutes before bed. It's a circadian signal, not a daytime supplement. Take it between meals, away from food.
On an empty stomach
Keep it away from protein-heavy meals
Space it a couple of hours from SAMe
On the label
Take 2 capsules with water 1 hour before bedtime.
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.
