Quercetin is a plant derived flavonoid found in fruits and vegetables, leaves, grains, red wine, onions, apples, berries, and chocolate. Quercetin is considered one of the most abundant antioxidant in human diet and plays a large role in fighting free radical damage, the effects of aging and inflammation. Quercetin can be taken in supplements and from foods.

Quercetin is an important anti-inflammatory because it act as an antioxidants, which mean it fights the natural process of “oxidation” that takes place over time.  Quercetin can help stop damaging particles in the body known as free radicals, which negatively impact how cells work including damaging cell membranes, changing the way DNA works, increasing cell mutations and causing healthy cells to die.

The first time I heard about quercetin was during the season I discovered I had allergies. I did research and found that quercetin helped with allergies. I started taking 500mg of quercetin daily. My symptoms took two weeks to disappear.

Quercetin is a natural antihistamine and an anti-inflammatory, making it effective for naturally lowering the effects of season and food allergies, plus asthma and skin reactions. Histamines are chemicals that are released when the immune system detects an allergy or sensitivity, and they are what account for uncomfortable symptoms we face whenever the body has an allergic reaction. Quercetin can help stabilize the release of histamines from certain immune cells, which results in decreased symptoms like coughs, watery eyes, runny noses, hives, swollen lips or tongue, and indigestion.

Quercetin is also known for:

  1. Promoting healthy immune function
  2. Promoting healthy blood sugar metabolism
  3. Promoting healthy lung and cardiovascular function
  4. Promoting healthy blood pressure
  5. Promoting cellular longevity.
  6. The richest sources of quercetin are found in red grapes, peppers, red wine, tomatoes, apples, onions, broccoli and berries.
