How to Take It
Best taken in the morning
Take earlier in the day with food. Check the conflicts below — it interacts seriously with serotonergic compounds.
With food
Label directs 3 servings — keep one for the morning
On the label
For adults, take one (1) capsule three times daily. Capsules may be opened and prepared as a tea.
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.
