Description

Quercetin is a flavonoid widely distributed in nature. It is a potent antioxidant and has anti-inflammatory activity, protecting cellular structures and blood vessels from the damaging effects of free radicals.

It improves blood vessel strength. Quercetin inhibits the activity of catechol-0-methyltransferase that breaks down the neurotransmitter norepinephrine. This effect may lead to elevated levels of norepinephrine and an increase in energy expenditure and fat oxidation.
