If you’re working on maintaining your blood sugar or cholesterol already within  the healthy range, you need to know about AMPK – your body’s metabolic master switch. When this switch is activated, you supercharge your body’s ability to metabolize blood sugar and cholesterol.* How can you “turn on” this switch? With berberine, a plant alkaloid found in goldenseal and Oregon grape root.* Our berberine is sustainably sourced from barberry and provides a clinically studied amount of 500 mg per vegetarian capsule, so you reap all the berberine benefits.
