PQQ is a nutrient that has a wide range of benefits. It has been shown to boost the immune system and improve memory.

It may help improve sleep quality, too. An open-label study showed that PQQ improved the sleep quality of 17 people with sleep-impairing disorders. After eight weeks of treatment, participants reported increased sleep duration, more restful sleep, and improved quality of sleep.

This is because PQQ boosts the activity of the enzyme lactate dehydrogenase, which is involved in energy production in many organs. In addition, it promotes the growth of new mitochondria.

There is evidence that the body needs a certain amount of PQQ for normal growth and function. Unlike in animals, the human body does not make PQQ. Instead, it is absorbed from dietary sources. A common dietary source of PQQ is fruits and vegetables.

Some researchers believe that PQQ has a role in preventing aging and improving cognitive functions. However, the evidence isn’t sufficient to say that it’s vital for humans. As with any supplement, it’s best to talk to your doctor before taking PQQ.

It may also lower stress levels and help reduce inflammation. The nutrient has been associated with a lower level of C-reactive protein and cortisol.

In addition, PQQ has been shown to increase blood flow to the cerebral cortex, which helps with thinking and memory. Additionally, the nutrient can enhance appetite. While more research is needed to determine how exactly it works, PQQ seems to be beneficial for humans.
