Quercetin

Among flavonoids it is among plant pigment flavonoids.
Quercetin is a natural pigment present in many fruits, vegetables and cereals.

Plants containing quercetin are: onions, apples, grapes, berries, broccoli, citrus fruit, cherries, tea and most of them are in capers.

The amount of quercetin in food depends on the conditions under which the plant was produced. For example, organic crops have a 50% higher content of quercetin. So we definitely need this antioxidant from another source (dietary supplements).
Quercetin is one of the most potent antioxidants and plays an important role in helping the body to combat the free radical-adverse effects associated with chronic diseases.

In addition, quercetin can help to reduce viral infection, inflammation, allergic symptoms and blood pressure.

Some research has shown that quercetin exhibits strong synergy with other flavonoids such as resveratrol, genistein and catechins.

Some scientifically justified effects of quercetin on the human body are:
– it may help to prevent infections caused by viruses
