Review: Scientifically proven studies of quercetin. - "Quercetin has antioxidant and anti-inflammatory effects which might help reduce inflammation, kill cancer cells, control blood sugar, and help prevent heart disease." "The data indicate that quercetin is the major neuroprotective component in coffee against Parkinson's disease and Alzheimer's disease.", "Some in vitro and animal-based research indicates that quercetin may protect against certain types of cancer, such as leukemia and lung cancer. For example, a 2010 study looked at the relationship between quercetin intake and lung cancer risk in 38 non-tumor lung tissues and found an inverse correlation—the higher the intake of quercetin, the lower the risk." "Very high doses—greater than 1 gram per day—might cause kidney damage.", Much Less than 1 gram/day needed. "Quercetin is known for its antioxidant activity in radical scavenging and anti-allergic properties characterized by stimulation of immune system, antiviral activity, inhibition of histamine release, decrease in pro-inflammatory cytokines, leukotrienes creation, and suppresses interleukin". "quercetin might help reduce inflammation. One studyTrusted Source on animals found that quercetin prevented both acute and chronic inflammation, in addition to showing anti-arthritis properties." "A 2015 report found that quercetin restricted the growth of prostate cancer cells in mice and rats. A 2018 in vitro study indicated that quercetin showed promise in both the treatment and prevention of prostate cancer." "Quercetin may help to prevent neurodegenerative diseases, such as Alzheimer’s or Parkinson’s disease. Oxidative stress contributes to the development of neurodegenerative diseases. Oxidative stress occurs when there is an imbalance of free radicals in the body. The antioxidant properties of quercetin may help fight free radicals. Research on rats showed that quercetin could protect against oxidative stress. It also showed quercetin could protect against the toxic effect of certain metals on the nervous system." Quercetin has been proven by Chinese scientists to remove neurotoxin effects of fluoride on the brain, when fluoride is drank in water supply, it acts as a neurotoxin killing brain cells and calcifying the pineal gland, quercetin removes these effects of fluoride.
