Bioflavonoids
Bioflavanoids are not really vitamins but are often associated with vitamin C. One bioflavonoid, or more correctly, simply flavonoid, is rutin, which is sometimes called vitamin P. The flavonoids are biologically active nutrients that include catechin, quercetin, rutin, and hesperidin. You find them in vitamin C-containing foods, such as fruits and vegetables. These beneficial chemicals support blood vessel strength and permeability and act as potent antioxidants to slow the aging process.
Key uses of bioflavonoids:
- Many flavonoids, such as quercetin and catechin, act as antiinflammatories and anti-histamines that help to reduce allergic responses.
- Flavonoids are also known to discourage viral replication, and they also act as antioxidants to protect your cardiovascular system and other tissues.
Where you can find it: Common sources include the white rinds of citrus fruits and many fresh fruits and vegetables, including green leafy vegetables like collard greens and kale, as well as grapes, cherries, and berries. Soy and green tea are also good sources.
How much to take: No RDA (recommended daily allowance) exists for bioflavonoids, but some should be taken along with vitamin C. Mixed bioflavonoids in the amount of 50 to 500 mg are commonly available in capsules and tablets.
Too little or too much: Toxicity is not known, while deficiency may weaken your blood vessel walls, contributing to varicose veins and making your body tissues more prone to swelling
