    What is Quercetin produced in NutraMax? Genistein is one of several known isoflavones. Isoflavones, such as genistein and daidzein, are found in a number of plants including lupin, fava beans, soybeans, kudzu, and psoralea being the primary food source,also in the medicinal plant, Flemingia vestita and coffee.Besides functioning as antioxidant and anthelmintic, many isoflavones have been shown to interact with animal and human estrogen receptors, causing effects in the body similar to those caused by the hormone estrogen. Isoflavones also produce non-hormonal effects.

    Genistein was first isolated in 1899 from the dyer's broom, Genista tinctoria; hence, the chemical name derived from the generic name. The compound nucleus was established in 1926, when it was found to be identical with prunetol. It was chemically synthesized in 1928.

     

    Where will Nutramax’s Quercetin be used for?

    Quercetin 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 relief of allergies and asthma.As an antioxidant, it reduces LDL cholesterol and offers protection from heart disease.

    Quercetin blocks an enzyme that leads to accumulation of sorbitol, which has been linked to nerve, eye,and kidney damage in diabetics.
