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.
On an empty stomach
Keep it away from protein-heavy meals
Space it a couple of hours from SAMe
On the label
Take 3 capsules per day on an empty stomach. Do not exceed 12 capsules in 1 day.
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.
