On the label

As a dietary supplement for adults, take two (2) tablets two times daily, between meals, or as directed by a healthcare practitioner.

The label says to take it on an empty stomach. What's in this one sits better with food, and you give up little by taking it that way.

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