PQQ is a substance that acts as a free radical scavenger and is a key antioxidant. It also promotes the activity of the mitochondria and reduces oxidative stress. As a result, it can help to reduce inflammation and protect the brain from neurodegenerative conditions.

Pyrroloquinoline quinone is a chemical compound that is present in papayas, fruits, and teas. Its presence in these plants suggests that it has been present throughout the evolutionary process. During the 1960s, pyrroloquinoline quinone was first identified as a cofactor for bacterial dehydrogenases. Over the next 15 years, its structure was elucidated.

In humans, pyrroloquinoline quinone plays a significant role in the growth of cells. It stimulates the production of the nerve growth factor. This is important for the development of new neurons and the maintenance of neuroplasticity.

Pyrroloquinoline quinone was also found to be beneficial in treating memory impairment in people with schizophrenia. It can also be used to protect against cardiovascular ischemic events. Several studies have shown that pyrroloquinoline quinone is able to increase the number of mitochondria in the brain, which leads to more cellular energy.

Moreover, pyrroloquinoline quinone can decrease markers of irritation in the body in three days. In addition, a number of animal studies suggest that it can lower triglycerides in the blood.

Other research shows that pyrroloquinoline quinone has been linked to the immune system, as well as cognitive function. Some research has shown that it can also help to improve sleep.
