Search and filter this category ↗Early cognitive findings are not a longevity claim
Pyrroloquinoline quinone, or PQQ, is marketed around cellular energy and cognitive performance. Human studies are much more limited than the mechanistic marketing suggests. A few short trials have explored memory measures, but those results need replication and do not establish that a supplement creates lasting mental sharpness or prevents cognitive decline.
Read the evidence limits and sources
The cited trial examined a defined dose over a limited period and does not prove dementia prevention, longer life or a general energy boost. Small studies and multiple cognitive outcomes warrant caution. Findings for the studied preparation do not verify the exact branded formula in this catalogue.
