Quercetin is a water-soluble plant pigment called a flavonoid.
It has anti-inflammatory properties and acts as an antihistamine.
Scientific studies also indicate that this flavonoid possesses potent antioxidant properties. Quercetin is found in onions, apples, green and black tea, and in small amounts it is found in leafy green vegetables and beans.
Cardiologists believe damage to LDL cholesterol (the ‘bad’ cholesterol) is an underlying cause of heart disease. Quercetin protects LDL cholesterol from becoming damaged. This flavonoid is said to block an enzyme that leads to the accumulation of sorbitol, which has been linked to nerve, eye, and kidney damage in those with diabetes; however, there is no evidence to support this action. Quercetin supplementation can also be used to treat prostatitis, allergies, asthma, atherosclerosis, cataracts, edema, gout, hay-fever, peptic ulcer, retinopathy.
Quercetin is more efficient when taken with Bromelain and Vitamin C (in the non-acidic form of magnesium ascorbate).
