TOP SUPPLEMENTS

Best Quercetin

Quercetin (pronounced kwur-si-tin) is a natural pigment found in colorful fruits and vegetables  think red apples, grapes, berries, peppers, broccoli, sweet potatoes, and onions.

It’s a powerful antioxidant and belongs to a group of polyphenol compounds known as bioflavonoids or flavonoids. Often referred to as the “master flavonoid”, it protects the body from free radical damage and supports overall good health and longevity.(See Reference 1)

Benefits of Quercetin

Inflammation

In our modern lives, we’re bombarded by free radicals from stress, poor sleep, pollution, and poor diet and lifestyle. This results in cell damage and inflammation in the body which can become chronic and cause a myriad of health issues.

Quercetin fights oxidative cell damage and has potent anti-inflammatory properties. (See Reference 2) Research suggests that diets high in antioxidant flavonoids like quercetin are associated with greater protection against disease.

In particular, quercetin can assist with painful, inflammatory conditions. Research has found that it inhibits the production of inflammatory hormones called prostaglandins and lowers inflammatory markers. One study found that 500mg of quercetin for eight weeks significantly reduced inflammatory markers, morning stiffness, and pain after activity for women with rheumatoid arthritis.(See Reference 3)

Allergies

Allergy symptoms — sneezing, runny nose, itching, watery eyes, hives, and rashes — are a result of an inflammatory chemical called histamine, produced by mast cells in the immune system to get rid of an irritant or allergen. Abnormal histamine release makes you feel lousy and can impact your quality of life.

Quercetin can prevent allergy symptoms and support respiratory health by acting as a natural anti-histamine. It stabilizes the mast cells and reduces histamine production.(See Reference 4)

Blood Pressure and Heart Health

Consuming potent antioxidants like quercetin lowers the risk of heart complications.

A 2016 review of 7 studies found that taking 500mg or more of quercetin per day can reduce systolic and diastolic blood pressure.(See Reference 5)

Quercetin supplementation may also support heart health in the following ways:

  • Reducing atherosclerosis – a buildup of plaque in the arteries(See Reference 6)
  • Lowering LDL cholesterol (the “bad” cholesterol) levels
  • Reducing total cholesterol levels
  • Preventing the oxidation of LDL cholesterol(See Reference 7)
  • Increasing healthy HDL cholesterol levels
  • Improving blood flow
  • Lowering blood triglycerides
  • Preventing abnormal blood clotting

Exercise Performance and Recovery

Quercetin’s ability to support healthy cardiovascular function and reduce inflammation makes it useful for those wanting to perform better and recover faster.

A 2011 review of 11 studies found that taking quercetin enhances exercise performance and capacity during endurance exercise.(See Reference 8)

Another study on cyclists found that 1000mg of quercetin daily minimized the likelihood of respiratory infections in the weeks following intense exercise, thus supporting recovery.(See Reference 9)

Blood Sugar

Antioxidant flavonoids encourage blood sugar balance. Research shows that diets rich in flavonoid compounds like quercetin — from berries, grapes, citrus, peppers, tea and red wine, — improve blood sugar control and reduce insulin resistance.(See Reference 10)

Gut Health

Quercetin may be a useful supplement to support gut health, especially for those suffering from a “leaky gut”. This occurs when the cells lining the gut become inflamed, damaged, and/or permeable. Undigested food particles, microbes and other foreign particles are then able to escape into the bloodstream and confuse the immune system.

In laboratory studies, flavonoids like quercetin were able to reduce gut inflammation and promote a strong intestinal barrier by tightening the junctions between gut cells.(See Reference 11)
