Quercetin belongs to a group of plant pigments called flavonoids. Flavonoids, such as quercetin, are antioxidants. They scavenge particles in the body known as free radicals which damage cell membranes, tamper with DNA, and even cause cell death. Antioxidants can neutralize free radicals. They may reduce or even help prevent some of the damage free radicals cause.
Benefits of Quercetin:
1. Lowers Inflammation: Flavonoids, including quercetin, are important anti-inflammatories because they act as antioxidants, which mean they literally fight the natural process of “oxidation” that takes place over time as we age. Quercetin can help stop damaging particles in the body known as free radicals, which negatively impact how cells work — including damaging cell membranes, changing the way DNA works, increasing cell mutations and causing healthy cells to die. Research now shows us that inflammation is the root of most diseases, including heart disease, cancer, cognitive decline, some mental disorders and autoimmune disorders. At this time, practitioners and patients report using quercetin to effectively fight conditions related to inflammation, including :
- hardening of the arteries” (atherosclerosis)
- high cholesterol
- heart disease and circulation problems
- insulin resistance and diabetes
- eye-related disorders, including cataracts
- allergies, asthma and hay fever
- stomach ulcers
- cognitive impairment
- viral infections
- inflammation of the prostate, bladder and ovaries
- chronic fatigue syndrome
- chronic infections of the prostate
- skin disorders, including dermatitis and hives
2. Fights Allergies: Quercetin is a natural antihistamine and an anti-inflammatory, making it effective for naturally lowering the effects of season and food allergies, plus asthma and skin reactions. Histamines are chemicals that are released when the immune system detects an allergy or sensitivity, and they are what account for uncomfortable symptoms we face whenever the body has an allergic reaction. Quercetin can help stabilize the release of histamines from certain immune cells, which results in decreased symptoms like coughs, watery eyes, runny noses, hives, swollen lips or tongue, and indigestion.
3. Supports Heart Health: Because of its ability to lower inflammation and oxidative stress, quercetin seems to be beneficial for people with heart and blood vessel-related disorders. Studies done in animal and some human populations show that various types of flavonoids (quercetin, resveratrol and catechins, for example) can help reduce the risk of atherosclerosis, which is a dangerous condition caused by plaque building up within the arteries.
4. Helps Fight Pain: Taking quercetin supplements can help lower pain associated with autoimmune conditions, such as arthritis, as well as infections, including those of the prostate and respiratory tract. That’s because quercetin reduces inflammatory pain. There’s some evidence from several small studies that people experiencing bladder pains from infections (causing an urgent need to urinate, swelling and burning) have fewer symptoms when taking quercetin supplements.
5. Might Help Improve Endurance: Quercetin is added to some athletic supplements because it’s believed to help increase athletic performance and endurance, likely because of its positive effects on blood flow. Researchers from the School of Applied Physiology at the Georgia Institute of Technology found that, on average, “quercetin provides a statistically significant benefit in human endurance exercise capacity (VO(2max) and endurance exercise performance).” Other studies also show that quercetin helps increase immune function and prevents susceptibility to illnesses that can occur when someone trains intensely and experiences exhaustion. One study found evidence that taking 500 milligrams of quercetin twice daily helped protect cyclers from developing exercise-induced respiratory infections following periods of heavy exercise.
6. Might Help Fight Cancer: A Boston University School of Medicine study published in the Journal of Biological Regulators and Homeostatic Agents shows a link between a nutrient-dense diet rich in quercetin plus other antioxidants and a lowered risk of cancer. Quercetin seems to have potential chemo-preventive activity and might have a unique antiproliferative effect on cancerous cells, making it an effective addition to any natural cancer treatment approach. Studies suggest that quercetin’s cancer-protecting effects result from the modulation of either EGFR or estrogen-receptor pathways. Flavonoids can help stop the processes involved in cell mutation, the growth of tumors and symptoms related to typical cancer treatments, such as radiation or chemotherapy. Quercetin is considered a safe treatment approach for stopping cancer, and in the future, we might see it used as a natural therapy instead of, or in conjunction with, conventional methods. At this time, the majority of studies done on quercetin’s effects on cellular functioning have involved animals, so more research is still needed to reveal quercetin’s specific effects on human cancerous cells. This is especially true when taken in high doses above the amount someone would get from a healthy diet.
7. Helps Protect Skin Health: Capable of blocking “mast cells,” which are immune cells critical in triggering allergic reactions, inflammatory disease and autoimmune disease, quercetin helps protect skin from the effects of disorders like dermatitis and photosensitivity. (14) Flavonoids like quercetin block the release of many pro-inflammatory cytokines, such as IL-8 and TNF, which helps stop symptoms related to skin inflammation, even in people who don’t find relief from other conventional treatments or prescriptions. Studies have found that quercetin’s potent antioxidant and anti-inflammatory compounds are natural ways to fight allergic and inflammatory diseases, as well as some prescriptions, when taken in oral supplement form.
