Potential benefits of taking a PQQ supplement and/or increasing pyrroloquinoline quinone intake
Searching for PQQ information?
If you are the type of person that concerns themselves with optimal nutrition, you probably have noticed that a few forward thinking nutritional companies have added a PQQ supplement to their line of products. Pyrroloquinoline quinone is quickly gaining in popularity as a potent antioxidant, rivaling both resveratrol and quercetin as the most beneficial nutraceutical of the three.
The purported benefits of pyrroloquinoline quinone supplementation include:
- An overall improvement in energy levels
- Improved cognitive function and memory
- Reduction in mitochondrial degradation
- Increased skin elasticity
- Enhanced nerve growth
So what do we know for sure so far about PQQ? We know it is required in the human diet; without pyrroloquinoline quinone our biochemical functions would cease to operate properly. In the 2003 Nature article Nutritional biochemistry: A new redox-cofactor vitamin for mammals the researches Takaoki Kasahara and Tadafumi Katopropose proposed that PQQ should join niacin and riboflavin under the umbrella of B vitamins. However, it is now generally accepted that pyrroloquinoline quinone is not a vitamin. This original claim was due to misinterpretation of the data in the Nutritional biochemistry: A new redox-cofactor vitamin for mammals article. It is now generally believed in the academic community that (rather than a vitamin) pyrroloquinoline quinone is better classified as one of a few compounds that act as cell signaling molecules.
Pyrroloquinoline quinone is prevalent in many foods associated with a healthy diet, so people that eat well-rounded meals should get enough to sustain their biological need. It is a water-soluble compound making it difficult to achieve PQQ toxicity. In short, taking a PQQ supplement should be considered safe for individuals absent of health problems. Pyrroloquinoline quinone is now being heavily marketed to those concerned with “aging well”. That is despite the fact that to date no published research exists using any type of whole organisms that address whether or not methoxatin has an independent or direct influence on aging. All of the work linking pyrroloquinoline quinone to aging is inferential and is based on PQQ’s ability to optimize mitochondrial function.
