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.
With or without food
On the label
Take 2 capsules 1–2 times per day or as directed by a health care professional.
General guidance based on the ingredients, not a substitute for the label or your doctor.
