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.

As a dietary supplement, adults take 2 capsules once to twice daily, with a meal and 8 oz. water, or as directed by your healthcare professional.
General guidance based on the ingredients, not a substitute for the label or your doctor.
