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
Mix 1 scoop with 10-16 ounces of water. Consume before, during or after exercise or sip throughout the day as a healthy energy drink substitute.
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.
