In addition to supporting mitochondrial health and cognitive function, PQQ has also been studied for its potential role in heart health. Some animal studies have shown that PQQ can reduce the risk of heart damage after ischemic events, such as a heart attack. It may also help lower blood pressure and improve lipid profiles by reducing levels of harmful LDL cholesterol. These cardiovascular benefits highlight the nutrient's potential as a key player in preventing one of the leading causes of death worldwide.
