Pyrroloquinoline quinone, also known as PQQ, is an important antioxidant. It is found naturally in several fruits and vegetables, including kiwifruit, papaya, and green tea.
When your body breaks down food, it produces free radicals. These radicals can cause damage to cells and lead to health issues, such as cancer. If your body produces too many of them, you may have problems with heart disease, diabetes, and aging. Fortunately, you can avoid these problems with PQQ.
PQQ is a potent growth factor in higher organisms. Because of this, it can help protect proteins and improve mitochondrial function. In addition, it is effective at neutralizing ubiquitous superoxide radicals. As a result, it is used in supplements to promote energy and overall brain health.
The chemical properties of pyrroloquinoline quinone are similar to those of riboflavin and pyridoxal-5-phosphate. But it is not easily self-oxidized, meaning it is less likely to become an inactive form.
A small number of PQQ-related studies have been conducted in humans, but very little is known about the potential benefits of supplementation. Many people take PQQ supplements for overall brain and heart health, increased energy, or enhanced focus. However, despite the potential benefits, there are no safety data available to confirm its effects.
Before taking PQQ, you should consult your doctor. Although there are no reports of serious side effects, it is possible to experience drowsiness or other mild effects. To avoid these problems, take the supplement on an empty stomach.
