Pyrroloquinoline quinone, or PQQ, is a small quinone molecule that is commonly found in a number of dietary sources, including papayas, kiwifruit, green peppers, parsley, and more. It is known to be an antioxidant that protects cells from oxidative damage.

PQQ also helps improve the quality of sleep. In fact, studies have shown that it can reduce the time it takes to fall asleep, as well as the length of time spent awake.

In addition, PQQ is said to help ward off neurodegenerative conditions. Its use is believed to reduce inflammation in the brain, as well as stimulate nerve growth factor, or NGF, in the body. This can promote the regeneration of dendrites in the brain, which can lead to improved signaling between neurons.

As a result, it may be used to treat strokes, as well as heart disease. It is also used to bolster the immune system. Another benefit of PQQ is its ability to boost cellular energy production.

Because of its many benefits, it is considered a “vitamin-like” substance. This means that it has the potential to be a nutrient, even though it does not exist naturally in the human body.

Although it is still unclear how much PQQ is needed to achieve its full benefits, it is often recommended that you consume it daily. Most dietary supplements are sold in a range of 20 to 40 milligrams.

If you are considering taking a supplement containing PQQ, it’s important to consult with your doctor before starting. While it has shown to be effective at boosting cognitive function, there are also negative reports of its side effects.
