Comparison
CoQ10 vs PQQ
CoQ10
Mitochondrial electron-transport cofactor. Naturally declines with age. Ubiquinol form is the active reduced state.
PQQ
Pyrroloquinoline quinone, cofactor in mitochondrial biogenesis. Found in fermented foods and breast milk.

The comparison in plain English
Two mitochondrial cofactors that work at different points in the energy chain. CoQ10 is an electron-transport-chain cofactor that declines with age and statin use. PQQ uniquely promotes mitochondrial biogenesis via PGC-1α, it makes more mitochondria.
Bottom line
They are complementary and are often stacked. CoQ10 improves the function of existing mitochondria; PQQ adds new ones. For users over 40, both are reasonable; under 30 the rationale is weaker.
Choose CoQ10 if
You take a statin, you have cardiovascular concerns, or you are over 50. 100–300mg ubiquinol form, with fat.
Choose PQQ if
You want mitochondrial biogenesis and have already covered the CoQ10 base. 10–40mg AM.
