The Buckler Brief

EVERYTHING YOU EVER WANTED TO KNOW ABOUT:

QUERCETIN

WHAT IT IS: Quercetin is an antioxidant flavonoid present in everything from wine and tea to onions and garlic. Apples, green vegetables and leafy greens also contain this powerful antioxidant. Quercetin is particularly helpful for overworked blood vessels, meaning it may help those seeking optimal heart health.

WHAT IT DOES: Quercetin is one antioxidant of many; other flavonoid antioxidants include polyphenols, red wine’s resveratrol, and tea’s catechins. All are vital to good health. In general, antioxidants destroy the dangerous free radicals that are responsible for many health problems that have roots in cellular damage. Quercetin is unique because it does more than the typical antioxidant – in addition to destroying free radicals and supporting cardiovascular health, quercetin may boost cellular energy levels.

STUDIES SHOW: Well-documented studies show [7] that quercetin is capable of blocking an enzyme called catechol-O-methyltransferase (or COMT). By inhibiting this enzyme, the level of a substance called norepinephrine is raised, creating several neat effects. Scientists think some of these may include increased energy expenditure and possibly more. It’s recently been shown that quercetin appears to support LDL (bad) cholesterol oxidation. This makes it a terrific supplement to support a healthy cardiovascular system.

In addition, quercetin is known to have antihistamine effects, making it a valuable antioxidant supplement for those troubled by allergies. Recent research has theorized that quercetin may also be beneficial to asthmatics for this very reason.

WHY WE LIKE IT: We really dig quercetin for its antioxidant properties and subsequent role in overall health. Since quercetin may help to fight heart problems (though this theory is not conclusive), we think it’s important for everyone.

Quercetin is also great for those with allergies because of its antihistamine effects. An important vasodilator, quercetin supports the cardiovascular system and may strengthen blood vessels. In addition, quercetin’s known ability to increase norepinephrine levels in the brain leads many scientists to believe quercetin may help to increase one’s cellular energy output. That’s one hard-working antioxidant!
