Bests & Worsts Reviews from Amazon

Excellent product especially when taken with CoQ.10, l carnitine fumarate, r alpha lipoic, d ribose and resveratrol. It has provided me with improved heart health and more energy.

The study was done by the VA Medical Center at UC San Francisco. In 2010 researchers found that "PQQ not only protected mitochondria from oxidative damage- it stimulated growth of fresh mitochondria!"
