Bioflavonoid Uses and Information

Bioflavonoids, generally referred to a flavonoids, are broken down into categories; however, the issue of how to divide them is not universally agreed upon. Bioflavonoids include isoflavones, anthocyanidins, flavonols, flavans, flavones, and flavanones. Some of the most popular flavonoids, such as genistein and quercetin, can be considered subcategories of categories. Although all bioflavonoids have similar structures, their functions are substantially different. Bioflavonoids also include hesperidin, rutin, citrus flavonoids, and a variety of other supplements.

Many flavonoids promote health by strengthening capillaries and other connective tissues in the body. Others function as anti-inflammatory, antihistaminic, and antiviral agents. Quercetin, one of the more common bioflavonoids, may even have possible health benefits for those suffering from diabetes. Rutin and several other flavonoids may also protect blood vessels.

Some flavonoids, such as quercetin, act as effective antioxidants inhibiting agents such as LDL (bad cholesterol) from causing oxidative damage to the body. Others, such as the anthocyanidins found in bilberry, purple cabbage, and grapes, possibly protect the eyes from developing cataracts.

Recommended Dosage

Health professionals commonly recommend 1,000 mg of citrus flavonoids taken one to three times per day for individuals not receiving enough in their diet. Alternatively, 240 - 600 mg of bilberry (standardized to 25 anthocyanosides) may be taken per day.
