How to Take It
Take it anytime
Studied as a twice-daily dose — its effect on bacterial adhesion is short-lived, so one big dose isn't equivalent.

Split into 3 doses across the day
On the label
Take 1 capsule three times daily with an 8 oz. glass of water or other liquid.
General guidance based on the ingredients, not a substitute for the label or your doctor.
