PQQ or pyrroloquinoline quinone is a B vitamin that was discovered relatively recently. Scientists knew about its existence earlier, but they considered it a vitamin-like compound and called it methoxanthine. It is interesting to study the properties of pyrroloquinoline quinone and understand why it is currently recognized as a complete vitamin.
What is pqq (pyrroloquinoline quinone)
Coenzyme PQQ, pyrroloquinoline quinone or methoxanthine, has long been considered a vitamin-like substance, that is, a compound that is necessary for the body to function, but does not have pronounced beneficial properties. It was only in the early 2000s that scientific research established that the substance methoxanthin has many beneficial properties and can be considered a real vitamin.
The discovery was made by Japanese scientists who conducted an experiment on laboratory mice and found that an increase in B14 levels really significantly affects the state of experimental animals. During the experiments, it was found that laboratory mice that regularly received PQQ in their diet began to look noticeably better than animals from the comparative group. The immunity of the experimental mice increased, the functioning of the reproductive system improved, the coat became thicker and softer.
Currently, there is still scientific debate regarding the role of pyrroloquinoline quinone. However, after research by Japanese scientists, most of the scientific community is inclined to consider vitamin B14 as an important element for human health.
PQQ belongs to vitamins resistant to high temperatures, but water-soluble and belongs to group B. In its natural form in the body, it is present in erythrocytes and primarily performs a transport function, responsible for the delivery of oxygen to tissues and organs.
Why does the body need pyrroloquinoline quinone
For the human body, PQQ, or pyrroloquinoline quinone, is of great importance. Its presence in cells affects the most important systems of the body:
- The cardiovascular system... Pyrroloquinoline quinone, present in red blood cells, plays an important role in the transport of oxygen and nutrients to organs and tissues. At a normal level of B14, the state of the vascular system and heart muscle improves, the oxygen supply to the brain increases. In turn, this reduces the risk of hypoxia and ischemia, protects the body from the development of dangerous cardiovascular diseases.
- Nervous system... Pyrroloquinoline quinone, or PQQ, has a beneficial effect on nerve cells and has a neuroprotective effect. Vitamin B14 protects nerve cells from decay and promotes their rapid regeneration, prevents the development of dangerous neurological diseases.

Thus, the use of PQQ helps to protect against colds, fungal and inflammatory diseases and to strengthen the immune system.
- Reproductive sphere... Scientific research confirms that pyrroloquinoline quinone, or vitamin B14, enhances the production of lysine, an amino acid important for the healthy functioning of the human reproductive system.
