As antioxidants, some bioflavonoids, such as quercetin, protect LDL-cholesterol from oxidative damage. Others, such as the anthocyanidins from bilberry, may help protect the lens of the eye from cataracts. Preliminary evidence suggests that some bioflavonoids, such as naringenin, may have anticancer activity.

In what conditions might bioflavonoids be supportive?

• atherosclerosis (quercetin, bilberry)
• bruising (bilberry)
• capillary fragility (quercetin, rutin, hesperidin)
• cataracts (quercetin, bilberry)
• circulation (bilberry)
• chronic venous insufficiency (hydroxyethylrutosides)
• diabetes (quercetin, bilberry)
• edema (water retention) (quercetin, rutin)
• gingivitis (periodontal disease)
• glaucoma (rutin)
• hay fever (quercetin, hesperidin, rutin)
• hepatitis (catechin, silymarin)
• high cholesterol (quercetin)
• minor injury
• macular degeneration (bilberry)
• menopause (hesperidin)
• menorrhagia (heavy menstruation)
• night blindness (bilberry)
• peptic ulcer (quercetin)
• retinopathy (bilberry)
• varicose veins (bilberry)
