How to Take It
Best taken in the morning
Live strains survive stomach acid best taken with or just before a meal — after a meal is the worst option. Consistency matters more than the clock.
With food
Keep it away from hot food or drink
Label directs 3 servings — keep one for the morning
On the label
1 capsule 3 times daily, preferably with meals, or as directed by a physician. Take at least 2–3 hours before or after antibiotics
