Discovered in 1979 inside a bacteria, pyrroloquinoline quinone (PQQ) is similar to vitamin B12. This compound cannot be produced by the body; however, there are many sources of PQQ in different fruits and vegetables including parsley, kiwi, papaya, tofu, etc. Because it aids in the production of new mitochondria, which is responsible for all activities at the cellular level, PQQ is known to improve overall health and well being. In addition, it is also a very potent antioxidant. Its benefits include alertness, increased cognitive performance, enhanced mental and heart health, decreased inflammation, improved quality of sleep, and more.
