Another notable benefit of PQQ is its potential role in cardiovascular health. PQQ has been shown to have antioxidant properties, which means it can help neutralize free radicals in the body. Excessive free radicals can lead to oxidative stress, a contributing factor in numerous chronic diseases, including heart disease. By reducing oxidative stress, PQQ may support heart health and improve overall cardiovascular function. Some studies have indicated that PQQ might also help lower LDL cholesterol levels, which is often referred to as “bad” cholesterol, providing yet another reason to consider its inclusion in a health regimen.
