How to Take It
Best taken in the evening
Calming herb — used in the evening. What's in this is easier on the stomach taken with food.
With food
Tyrosine 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
Label directs 2 servings — keep one for the evening
On the label
Two tablets daily during or immediately after a meal, or as directed by a healthcare professional
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.
