PQQ is a quinone compound that was first discovered in the early 1970s. It is found in a variety of foods, particularly in fermented products, and is known to play a critical role as a cofactor in enzymatic reactions. PQQ supports the function of certain dehydrogenases and is involved in cellular respiration, aiding the conversion of glucose and other substrates into energy. One of the key aspects of PQQ is its ability to stimulate mitochondrial biogenesis, a process that enhances the number and function of mitochondria within cells.


Thymus Supplements A Comprehensive Overview


The potential effects of PQQ extend beyond neuroprotection and mitochondria. Emerging research indicates that PQQ may have a positive impact on cardiovascular health. By improving endothelial function and reducing inflammation, PQQ could help lower the risk of heart disease and promote overall cardiovascular wellness. Moreover, its effects on glucose metabolism suggest it might play a role in managing blood sugar levels, which is particularly beneficial for individuals with insulin resistance or diabetes.
