How it works
Promotes mitochondrial biogenesis and supports cellular energy metabolism.
Overview
PQQ is a redox cofactor that has been studied for its role in stimulating mitochondrial biogenesis, potentially improving cellular energy efficiency. It is often paired with CoQ10 for synergistic effects on energy metabolism. While human research is still emerging, it shows promise for long-term brain health and cognitive resilience rather than immediate performance enhancement.
