How to Take It

Best taken in the evening

The Glycine in it is what pulls this toward the evening. Carnitine is easier on the stomach taken with food.

With food

On the label

As a dietary supplement, take one veggie capsule one to two times per day with water on an empty stomach.

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.
