Quercetin is a bioflavonoid and a natural pigment

Quercetin is a bioflavonoid and a natural pigment found in all herbs, fruits and vegetables. Flavonoids have anti-inflammatory and antioxidant protective effects in the body, and quercetin is also one of the most powerful herbal anti-inflammatory antioxidant supplements available. In fact, quercetin has been shown to have a preventive effect on a wide range of inflammatory and free radical-damaging diseases including arthritis, allergies, macular degeneration, heart disease, gout, and various cancers.

Quercetin can play a role in preventing cancer by blocking the oxygen and nutrient circulation of cancer cells, effectively cutting off their food supply. Quercetin is also a phytoestrogen that mimics the effects of human estrogen; Quercetin binds to the estrogen receptor where estrogen is located, so it can make the estrogen that breast cancer needs to stimulate growth lose its effect.

Studies have confirmed that quercetin derived from citrus fruits can reduce the growth rate of breast cancer cells by about 50%. In addition, animal-based trials have confirmed that quercetin inhibits the growth of colon, prostate, breast and lung cancer cells.

Quercetin can also treat allergic reactions by blocking histamine secretion in the body. Histamine causes inflammation and swelling, as well as runny nose, itchy eyes, sneezing and other irritating symptoms associated with allergies. In laboratory studies, quercetin also inhibits inflammation in arthritis patients and the inflammatory symptoms of prostatitis. Studies have found that switching to a flavonoid-rich diet can significantly improve symptoms in patients with rheumatoid arthritis. For example, taking 500 mg of quercetin per day can improve the symptoms of pelvic pain in patients with prostatitis. In addition, preliminary clinical studies have confirmed that quercetin also has the effect of inhibiting the growth of prostate cancer cells.

Quercetin is also effective in treating skin-related inflammatory diseases. It increases the body's production of collagen and fibronectin, two substances needed to keep joints and skin healthy. Therefore, quercetin is good for arthritis patients, people who want to reduce or prevent wrinkles. Quercetin is also an active ingredient in many cosmetic beauty products and can delay or reduce the signs of aging. In addition, quercetin also has the effect of promoting wound healing, especially for nerve tissue damage in skin trauma has a good repair effect.

Quercetin reduces the risk of heart disease by preventing the accumulation of arterial macrophages. Macrophages contain a large number of proteins that can easily harden into plaque and cause arterial thrombosis or atherosclerosis. In addition, quercetin can also promote blood circulation by strengthening capillaries throughout the body, helping to prevent eye diseases caused by poor blood circulation, such as cataracts, macular degeneration and diabetic retinopathy.

Quercetin can be found in almost all plant foods. For example, foods such as black tea, broccoli, onions, red apples, and red wine are the best sources of this nutrient. Quercetin supplements come in the form of concentrated powders, tablets or capsules. It is often packaged with bromelain, another substance that is helpful in treating allergies and inflammation, and promotes the body's absorption of quercetin. The typical intake dose of quercetin is 100-250 mg three times a day.
