About PQQ
Pyrroloquinoline quinone (PQQ) is a naturally occurring, vitamin-like compound with significant antioxidant properties. It plays a role in mitochondrial biogenesis, potentially enhancing cellular energy production and overall health. Research suggests benefits in areas such as cognitive function, cardiovascular health, and nerve growth. While generally considered safe at recommended dosages (20-40mg daily), mild side effects like headache or insomnia may occur in some individuals. Its mechanism of action involves stimulating mitochondrial biogenesis, reducing oxidative stress, and promoting nerve growth factor production.
