Flavonoids are a class of antioxidants, also known as polyphenols, responsible for colors in many fruits and flowers.  Quercetin is the most widely consumed flavonoid.  Common sources of flavonoids :

  • Apples, citrus fruit, berries
  • Onions, parsley, legumes
  • Green tea  and red wine

Quercetin has been used in Europe and Russia to treat inflammation and allergies.

Quercetin affects inflammation by decreasing the production of inflammatory mediators by inhibiting key enzymes.  Quercetin works at the same site as aspirin and other over the counter anti-inflammatories.  Here are a few diseases where quercetin may help:  eczema, rheumatoid arthritis, osteoarthritis, other chronic inflammatory joint disorders and allergic responses.

Quercetin is nature’s antihistamine.  It inhibits both the manufacture and release of histamine and other allergic and inflammatory compounds.  It does this without drowsiness.

Flavonoids are referred to as ‘nature’s biological response modifiers’.  Mayo Clinic researchers reported ‘that plant-based nutrient quercetin may provide a potential non-hormonal approach to preventing or treating prostate cancer.’  The same holds true for breast cancer.  Another study shows quercetin may also reduce the risk of lung cancer.  This plant compound seems to bolster wellness.

People consuming high levels of dietary quercetin have reduced blood pressure, lower stroke risk and lower death rate from ischemic heart disease.  Quercetin inhibits the formation of blood clots helping to prevent cardiovascular disease.  It also reduces capillary fragility and may prevent diabetic cataracts.

Quercetin from onions is more bioavailable than quercetin in apples.  The sugar content slows the absorption and decreases the availability.  The typical dose of quercetin is 200mg- 400mg. taken three times a day.   If you plan on using this supplement for allergies, keep in mind it may take a couple of days for your body to get a level high enough to notice dramatic results.  Quercetin has no known side effects and appears to have great benefits.  A good reason to eat your fruits and veggies.
