How to Take It
Check the label before you take this
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
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 capsules per day on an empty stomach or as directed by your health-care practitioner.
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.
