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

As a dietary supplement, take one serving, 1-2 times daily, mixed with a beverage or into food.

General guidance based on the ingredients, not a substitute for the label or your doctor.
