What is Pure Quercetin Dihydrate Powder?
Our Pure Quercetin Dihydrate Powder is derived from the flower of Sophora japonica. And its main ingredient is quercetin, which 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-O-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. It also means quercetin acts as an antihistamine leading to the relief of allergies and asthma.
