BioPQQ is formulated to provide a fermented form of PQQ to maximize absorption. Each capsule contains this highly absorbable form of PQQ. Our formulation promotes cellular health by helping the body generate mitochondria. More mitochondria is important as cells require them to produce energy (the heart and brain especially). This bioavailable supplement is third-party certified by ISURA which tests for GMOs and about 800 contaminants.
