3. Key Functions & Health Benefits (Evidence-Based)

(1) Supports Mitochondrial Biogenesis

PQQ stimulates PGC-1α, helping the body create new mitochondria—critical for energy metabolism.
Reference: Chowanadisai et al., J Nutr Biochem. 2010.

(2) Cognitive & Neuroprotective Benefits

Studies show PQQ may reduce oxidative stress and support memory and attention.
Reference: Nakano et al., Food Funct. 2012.

(3) Cardiovascular Support

Supports endothelial function and reduces inflammatory markers.

(4) Potent Antioxidant Activity

PQQ can undergo thousands of redox cycles, giving it a unique antioxidant profile compared with typical polyphenols.

(5) Stress Reduction & Sleep Quality

Human trials indicate improved sleep quality and reduced fatigue scores.

These claims are based on published research; buyers should adjust marketing claims according to local regulations.
