All about quercitin

by: John Gibb

In this article, we'll explain all about quercitin that you need to know. Quercitin, a bioflavonoid ( a type of nutrient that is found in some fruits and green, leafy vegetables, amongst other things such as teas and beans) can be a great asset to your health when taken as a supplement to a healthy diet. Bioflavoniods are the nutrients necessary to maintaining the health of your skin. This is because they help to create collagen, the substance that keeps our skin firm and healthy. Therefore, a lack of collagen can lead to wrinkles and sagginess. Quercitin has also been shown to help the body improve the health of its capillaries and connective tissues. Due to this, quercitin has been linked to helping to alleve bruising, unsightly varicose veins, fragile cappilaries, and edema. Also, good news for allergies! Quercitin has been known to block the release of histamine, which may help aid conditions brought on by allergies. After testing at the Mayo clinic, quercitin was also shown to be useful in helping to treat or prevent prostate cancer. In the findings of the Mayo Clinic study about quercitin, Mayo Clinic researcher Nianzeng Xing, Ph.D stated that "Our laboratory results showed quercitin blocks the androgen activity in androgen-responsive human prostate cancer cell lines." He then followed this statement by asserting that "By blocking the androgen activity, the growth of prostate cancer cells can be prevented or stopped." While this research doesnt prove quercitin will actually truly benefit men with prostate cancer or those at risk, it definitely shows promise as a preliminary study. While there is not a recommended daily allowance, or RDA, of quercitin, studies have indicated that toxicity with quercitin is largely a non issue. However, a dosage of somewhere between 50 mgs and 150 mgs per day is a reasonable dose, and using mega-doses is not recommended. If you are pregnant or nursing, it would be a good idea to speak with your physician before beginning taking this supplement.
