Factory supply High quality Quercetin dihydrate
Description of Quercetin dihydrate
Quercetin dihydrate is a potent antioxidant and has anti-inflammatory activity, protecting cellular structures and blood vessels from the damaging effects of free radicals. Quercetin dihydrate improves blood vessel strength. Quercetin dihydrate 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. Quercetin dihydrate also means quercetin acts as an antihistamine leading to relief of allergies and asthma. As an antioxidant, quercetin powder reduces LDL cholesterol and offers protection from heart disease. Quercetin dihydrate blocks an enzyme that leads to accumulation of sorbitol, which has been linked to nerve, eye, and kidney damage in diabetics.
