 Quercetin aids in zinc absorption into cells, optimizing its utilization, while zinc enhances the antioxidant properties of quercetin.

Bioactive Components

Quercetin is part of the flavonoid group known for its antioxidant abilities, helping to neutralize free radicals in the body. It is also recognized for its ability to modulate a number of biological processes which are integral to health maintenance.

Quercetin in Diet

Quercetin is abundant in foods like onions, apples, grapes, berries, broccoli, capers, and tea. Regular consumption of these foods can help achieve its benefits without supplementation.

Supplementation

Quercetin supplements are available in various forms, including capsules, tablets, and powders. Common dosages range from 500 to 1000 mg per day. Supplements often contain quercetin dihydrate, a form that may be easier for the body to absorb.

Research and Studies

Numerous studies support the health benefits of quercetin, though more research is often cited as necessary to confirm these effects fully, particularly in human trials as opposed to laboratory or animal models.

Safety and Side Effects

Quercetin is generally safe when consumed in food or taken as supplements in moderate amounts. However, high doses might cause headaches and tingling of the extremities. People with kidney disease should avoid quercetin supplements.

Health Benefits

Anti-inflammatory Effects

Quercetin is noted for its ability to fight inflammation, potentially beneficial in conditions such as arthritis and asthma.

Antioxidant Properties

As an antioxidant, quercetin helps to protect cells from oxidative stress and damage, which could otherwise lead to chronic diseases.

Cardiovascular Health
