In conclusion, PQQ presents a promising avenue of research in the field of heart health. Its antioxidant properties, capacity to enhance mitochondrial function, anti-inflammatory effects, and potential to improve lipid profiles suggest that it could play a significant role in maintaining cardiovascular wellness. Although further studies are needed to fully understand the extent of PQQ’s impact on heart health, the existing evidence indicates that it could be a valuable addition to the dietary strategies aimed at promoting a healthier heart. As always, individuals should consult healthcare professionals before making significant changes to their diet or supplement regimen, particularly those with existing heart conditions or other health concerns.
