Cognitive health is another area where PQQ shows immense promise. Research has demonstrated that PQQ may help protect against neurodegenerative diseases and cognitive decline. By supporting mitochondrial function, PQQ can facilitate better energy supply to brain cells, which is critical for optimal cognitive performance. Additionally, PQQ possesses neuroprotective properties that may help reduce oxidative stress in the brain, promoting mental clarity and memory retention. For those looking to boost their cognitive abilities, especially during stressful or demanding periods, PQQ lozenges could serve as a beneficial addition to their regimen.
