Pyrroloquinoline quinone (PQQ), otherwise known as methoxanthin, it is substance that was discovered quite recently. Admittedly, PQQ was discovered in 1979. However, it was not until 2003 that its properties were shown to be similar to those of B vitamins (for this reason, it is sometimes called PQQ vitamin).
Nonetheless, PQQ is not a vitamin but a vitamin-like substance because it does not meet all the criteria for this group. PQQ functions as a cofactor, thereby regulating enzyme activity.
It is a cofactor of many redox reactions with great antioxidant and anti-inflammatory potential. It has been shown to be more effective than the commonly used vitamin C.
Furthermore, PQQ stimulates the biogenesis of mitochondria (increases the body’s efficiency, improves energy production), helps maintain normal protein deglycase DJ-1 levels (protects against oxidative stress), is involved in NGF synthesis (promotes the production of new neurons and regeneration of myelin sheaths).
All these properties may make PQQ supplementation a perfect way to improve general quality of life (improved sleep efficiency, increased energy levels, reduced stress and fatigue and a beneficial impact on mood).
