What is quercetin?

Quercetin is a phytochemical, a so-called flavonol from the group of polyphenols. In the plant kingdom, the substance occurs mainly in onions, broccoli, apples, grapes, black and green tea. This natural substance has, among others, the function of providing a yellowish colour to many plants, and is therefore mainly found in the marginal layers. Phytochemicals have aroused a great interest, not only in terms of nutrition but also due to their positive properties, since they have also become the subject of modern scientific research.
