In addition to its antioxidant capabilities, PQQ has been found to have a positive influence on mitochondrial function. Mitochondria are often referred to as the powerhouses of the cell, generating energy in the form of adenosine triphosphate (ATP). Research shows that PQQ can promote the growth of new mitochondria, a process known as mitochondrial biogenesis. This feature is particularly beneficial for aging populations, as mitochondrial function tends to decline with age, leading to decreased energy levels and increased fatigue. By supporting mitochondrial health, PQQ may enhance overall energy metabolism, improve physical performance, and reduce the susceptibility to age-related diseases.
