How to Take It

Take it anytime

With or without food
Split into 3 doses across the day

On the label

As a herbal supplement, adults take two (2) capsules with any meal three times daily or as directed by a healthcare provider. Do not exceed recommended dosage.

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