Why bioflavonoids are good for you

Bioflavonoids (also called flavonoids), and are the substances that give fruits and vegetables their bright beautiful orange-yellow colours.

Bioflavonoids are powerful antioxidants.

Bioflavonoids not only help to get rid of the free radicals, they also increase the action of other antioxidant nutrients.

The immune system requires a lot of bioflavonoids to help run it at peak levels.

Bioflavonoids act together with vitamin C to help maintain the thin walls of the capillaries, therefore preventing excessive bleeding or bruising. Bioflavonoids have been linked to having an antibacterial effect, stimulating bile production, promoting circulation and even assisting with fighting allergies, allergic rhinitis (hay fever) and asthma. Bioflavonoids also help with lowering blood cholesterol levels and in the prevention and treatment of cataracts.

The main bioflavonoids are: Citrin, Hesperidin, Rutin and Quercetin.
