How to Take It
Best taken in the evening
Used in the evening for relaxation. PS 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
Space it a couple of hours from SAMe
On the label
Take 2 vegcaps 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.
General guidance based on the ingredients, not a substitute for the label or your doctor.
