History and Characteristics :
Bioflavonoids are a water-soluble group composed of many brightly colored nutrients found in fruits and vegetables. Bioflavonoids are insoluble in oils and stable in acid. They are partially lost in frozen fruit juices. Boiling will destroy bioflavonoids but steaming will not.
Bioflavonoids are not sold as an individual supplement but instead are added to vitamin C. The best source of natural bioflavonoids is the white rind of any citrus fruit, especially lemons, oranges and tangerines. Frozen orange juice is not a good source of bioflavonoids because the pulp that contains the complex is squeezed off by processors.
Bioflavonoids were discovered by Dr. Albert Szent-Gyorgyi as an offshoot of vitamin C. Discovered in the white pulp surrounding citrus fruit, the group of compounds was named vitamin P because it is concerned with the permeability of the capillaries. Composed of citrin, hesperidin, rutin, flavones and flavonals, bioflavonoids are sometimes called by the names of individual components.
The main function of bioflavonoids is to assist vitamin C in its work. Their first specific task is to keep the collagen healthy and the capillaries elastic and permeable to diffuse and absorb nutrients. Afterwards the bioflavonoids travel through the circulatory system to parts of the body where they are needed. Bioflavonoids also act as anticoagulant fac tors, stopping capillaries from breaking and causing bruising.
Bioflavonoids are easily absorbed in the intestinal tract, from there going into the circulatory system. Any excessive amount is sloughed off through urination or perspiration.
Allies: Vitamin C. -
Antagonists: Since bioflavonoids are synergists with vitamin C, some of the same antagonists of vitamin C may affect the bioflavonoid complex. (See section on vitamin C.) But further research needs to be done to prove this theory.
Recommended Dietary Allowance: None has been established by the FDA.
Therapeutic Dose: Fi fty to two hundred milligrams are recommended.
Megadose: Two hundred or more milligrams are recommended.,
Bioflavonoids are completely nontoxic.
One of the first signs of a potential deficiency of bioflavonoids is bruising of the skin. Such bruising means that the capillaries are fragile and are breaking with the slightest amount of pressure placed against the skin. Where the capillaries are damaged the skin may be pale pink, splotchy red or purplish. Furthermore, there is general swelling in the area from excess fluids beneath the skin.
A deficiency of bioflavonoids will also bring on problems with bleeding, especially for a person who tends to bleed easily. A bleeding wound may take longer than usual to heal. And there may be an irregular menstrual flow or pain associated with the loss of blood.
