PQQ (pyrroloquinoline quinone) is an amino acid that has shown significant anti-oxidative effects. It has been found in many foods, including green peppers, kiwifruit, parsley, soy and natto.

In fact, a number of studies have suggested that this amino acid may be beneficial for a variety of different health conditions. For instance, it has been found to increase energy levels and promote healthy sleep. This may also contribute to the reduction of oxidative stress and inflammation.

PQQ has also been found to increase a protein called CREB, which is involved in growth and development. Studies have shown that PQQ increases the amount of BDNF, which may help to improve cognition.

Although research is limited to animal studies, it is possible that PQQ may have benefits for humans. The nutrient is known to be present in human breast milk and is also incorporated into fermented soy products such as natto.

PQQ is believed to be a non-vitamin growth factor that increases the rate of cell proliferation. It is believed that a high level of PQQ in the diet may be required for normal growth and development.

PQQ has also been shown to reduce the inflammation of the liver in mice. Specifically, researchers have found that feeding PQQ to adult mice prevented fatty liver disease. They also found that omitting PQQ from the diet caused a number of immune defects.

As with most supplements, it is important to buy PQQ from a reputable brand. If you do decide to use a supplement, it is recommended that you begin with a lower dosage and then work your way up gradually.
