How to Take It
Best taken in the evening
Take 30–60 minutes before bed. St. John's Wort is easier on the stomach taken with food.
With food
Do not combine with 5-HTP, SAMe or Tryptophan
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.
