As a new water-soluble vitamin, PQQ is a redox enzyme cofactor. It is very rare and exists in some microorganisms, plants and animal tissues. A small amount of PQQ can increase the metabolism and growth of biological tissue, which is extremely precious. Although it is only a product of some bacteria, it is interesting that a very small amount of PQQ is found in various plants, animals and humans. Japanese scientists measured the content of PQQ in 26 common foods and found that it ranged from 3.65 to 61 ng in 1 gram of food. For example, parsley, green pepper in vegetables, kiwi and papaya in fruits, green tea and oolong tea in drinks, and tofu that people often eat are about 30 ng/g. To our surprise, the PQQ content in human milk is as high as 140-180 ng/ml. The mother's milk contains such a high concentration of PQQ, which indicates that this substance may play a vital role in the growth and development of newborn infants. Since PQQ is so important, let's take a look at its food and beverage sources.
PQQ naturally occurs in almost all foods, ranging from 0.19 to 61ng/g, but is especially concentrated in the following foods:

6 Beverage Sources of PQQ
Drink Type | Nanograms of PQQ Per Milliliter of Drink | |
1 | Green Tea | 29.6 |
2 | Oolong Tea | 27.7 |
3 | Coke | 20.1 |
4 | Wine | 5.79 |
5 | Sake | 3.65 |
6 | Skim Milk | 2.50 |
The study suggested that all vegetables and fruit contain at least some amount of PQQ.
The PQQ content of even the most PQQ-rich foods is much lower than the amount you can get from a supplement (5 to 20 mg).
