Hesperidin, rutin, and narignin are the principal citrus bioflavonoids and are found in lemon, grapefruit, and orange juices, although other bioflavonoids are also present.
The most recent scientific breakthroughs confirm that these incredible nutrients are an important part of a healthy diet. Their healing properties promote longevity and play a role in the prevention of cancer and heart disease. They can even make you smarter and improve the appearance of your skin.
So far 5,000 different types of flavonoids have been identified, and of these, a hundred or so have been shown to have biological effects in humans. These are called bioflavonoids. Several bioflavonoids, including quercetin, cathechin, and hespiridin, have scientific research backing their health benefits. In fact, many nutritionists believe that not getting enough of these precious substances from your diet may cause premature aging, degenerative diseases, and death. But by making a few simple nutrition choices and by taking the right bioflavonoid supplements, you can improve the quality of your life and perhaps extend your years.
