PQQ Pyrroloquinoline quinone supplement

PQQ is available as a dietary supplement and claimed to support mitochondrial health and cellular energy production, and as an antioxidant. There are claims that PQQ stimulates the spontaneous growth of new mitochondria in aging cells, and activates genes that govern mitochondrial protection and repair.

In animals, PQQ is reported to participate in a range of biological functions with apparent survival benefits (e.g., improved neonatal growth and reproductive performance). There are also benefits from PQQ supplementation related to cognitive function, immune, and antioxidant functions, as well as protection from cardiac and neurological ischemic events. PQQ is involved in cell signaling pathways, particularly those important to mitochondriogenesis.

Q. I stumbled across a reference to PQQ  today, and have been looking for information since. What do you think of this newest vitamin?
   A. there is very little human research with pqq and he is awaiting results of more studies before determining whether this product has advantages over existing, and better studied, antioxidants and cognitive enhancers.
