How to Take It

This product combines a stimulant with a sleep-supporting ingredient, so there's no single good time to take it. Follow the label and keep it well away from bedtime.
With food
Keep it away from protein-heavy meals
Space it a couple of hours from Iron, Calcium and SAMe
On the label
Take 6 capsules daily.
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.
