How to Take It
Best taken in the evening
Take in the evening. Amino acids compete for the same transport into the brain, 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
Label directs 3 servings — keep one for the evening
On the label
Adults: Take 1 caplet 3 times daily with a meal. To help promote healthy mood balance, use for a minimum of 1 week to see beneficial effects. To help relieve symptoms of fibromyalgia, use for a minimum of 2 weeks to see beneficial effects. Consult a health care practitioner for use beyond 1 year
Labels usually say “with food” because it's gentler on the stomach, not because it absorbs better. Fasted absorbs more — start there, and switch to a light meal if it bothers you.
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.
