What is Quercetin?

Quercetin, a flavonoid found in fruits and vegetables, has unique biological properties that may improve mental/physical performance and reduce infection risk . These properties form the basis for potential benefits to overall health and disease resistance, including anti-carcinogenic, anti-inflammatory, antiviral, antioxidant, and psychostimulant activities, as well as the ability to inhibit lipid peroxidation, platelet aggregation and capillary permeability, and to stimulate mitochondrial biogenesis.

Therefore, there is a pressing need for well-designed clinical trials to evaluate this novel dietary supplement further. This article reviews effects of quercetin on inflammation and immunity in mental and physical performance and health.

Physicochemical Properties of Quercetin

Quercetin is categorized as a flavonol, one of the six subclasses of flavonoid compounds. The name has been used since 1857, and is derived from quercetum (oak forest), after Quercus. It is a naturally occurring polar auxin transport inhibitor. The International Union of Pure and Applied Chemistry (IUPAC) nomenclature for quercetin is 3, 3′, 4′, 5, 7-pentahydroxyflvanone (or its synonym 3, 3′, 4′, 5, 7-pentahydroxy-2-phenylchromen-4-one). This means that quercetin has an OH group attached at positions 3, 5, 7, 3′, and 4′. Common forms of quercetin were shown in Figure 1.

What Is Quercetin Used For?

People take quercetin to try to manage a variety of issues, including:

  • Heart and vessel problems
  • Lowering blood pressure
  • Prostate infections
  • Preventing upper respiratory infections
  • Allergies
  • Disease prevention

Early quercetin research on heart and vessel disease is mixed. Some study results are positive but some are open to debate. For example, researchers link eating lots of foods high in quercetin to a lower risk of heart-related death in older men. But other studies are less convincing.

Some research suggests that oral doses of quercetin may decrease pain from prostate infections.

Quercetin supplements are available as pills or capsules. They are often packaged with bromelain (an enzyme found in pineapple) because both are anti-inflammatories. Other flavonoid-rich extracts include those from grapeseed, bilberry, Ginkgo biloba, and green tea.

There are also water-soluble forms of quercetin available, such as hesperidn-methyl-chalcone (HMC) or quercetin-chalcone.
