As the primary engines of almost all bioenergy production, the mitochondria rank among the physiological structures most vulnerable to destruction from oxidative damage. PQQ’s formidable free radical–scavenging capacity furnishes the mitochondria with superior antioxidant protection.
At the core of this capacity is an extraordinary molecular stability. As a bioactive coenzyme, PQQ actively participates in the energy transfer within the mitochondria that supplies the body with most of its bioenergy (like CoQ10).
Unlike other antioxidant compounds, PQQ’s exceptional stability allows it to carry out thousands of these electron transfers without undergoing molecular breakdown. It has been proven especially effective in neutralizing the ubiquitous superoxide and hydroxyl radicals. According to the most recent research, “PQQ is 30 to 5,000 times more efficient in sustaining redox cycling (mitochondrial energy production) . . . than other common [antioxidant compounds], e.g. ascorbic acid.” A consistent finding in the scientific literature is that nutrients like PQQ provide more wide-ranging benefits than conventional antioxidants the general public relies on.

PQQ - What Does it do - Gabi Giacomin
"Bioactive compounds (PQQ) reported to stimulate mitochondrial biogenesis are linked to many health benefits such as increased longevity, improved energy utilization, and protection from reactive oxygen species.
Previously studies have shown that mice and rats fed diets lacking in pyrroloquinoline quinone (PQQ) have reduced mitochondrial content. Therefore, we hypothesized that PQQ can induce mitochondrial biogenesis in mouse hepatocytes...
...The ability of PQQ to stimulate mitochondrial biogenesis accounts in part for action of this compound and suggests that PQQ may be beneficial in diseases associated with mitochondrial dysfunction." Source
The use of PQQ is endorced and recommended by the Trisomy 21 Research Foundation, it is contained within their new Polyphenol Support Formula. However Dr Erica Peirson, from the Peirson Center stated this in February 2015
