Pyrroloquinoline quinone, or PQQ, is an essential factor for human health. It is an antioxidant, neuroprotectant, and is known to reduce inflammation. However, there is little research to back up the use of PQQ as a supplement.

The pyrroloquinoline quinone was first discovered in bacteria, where it serves as a coenzyme for enzyme reactions. As a result, it is similar to a B-vitamin.

Interestingly, PQQ is also absorbed from fruits and vegetables. Although it is known to have antioxidant properties, there is a lack of data to support its use. Despite its many benefits, there are also a few side effects that may be a concern.

PQQ is commonly marketed as a supplement, usually as capsules or soft gels. Most supplements are sold in the 20-40 mg range. If you are taking medication for high blood pressure, diabetes, or any other medical condition, talk to your doctor about taking PQQ.

The pyrroloquinoline quinonone is safe when taken in low doses. Higher doses are associated with dangerous effects. High doses can cause death in rats. In addition, there are concerns that it can affect the liver.

While there are several promising studies, there is not yet enough evidence to suggest that PQQ has a positive impact on human health. Nevertheless, there is some evidence to support its potential as a therapeutic nutraceutical.

PQQ is a member of the quinoprotein class of cofactor molecules that transfer electrons to other compounds. This function is crucial for the mitochondria, which produce energy.
