How to Take It
Best taken in the evening
Take at night. Other amino acids compete for brain uptake, so a protein-heavy meal blunts it. Take it between meals, away from food.
On an empty stomach
Keep it away from protein-heavy meals
Space it a couple of hours from SAMe
On the label
Take 10.4 grams once (1x) daily with 8 fl oz of water or your favorite beverage.
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.
