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 correlationâ€"the higher the intake of quercetin, the lower the risk." "Very high dosesâ€"greater than 1 gram per dayâ€"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

A great product – unfortunately, I don't think I can buy it at the new price

I have been taking this marvelous product for about two years and I have sent bottles of it to my brother and all my friends and relatives across the country. My brother said it stopped his COPD. I have NO immune system - so you can imagine how much I need this. Right now I am battling shingles, cellulitis, Lyme, kidney/bladder infection besides all the usual - which is a very long list that includes rheumatoid arthritis, pituitary tumor (and with that, hypothyroid, adrenal insufficiency, human growth hormone deficiency, and diabetes insipidous), and more - it's a very long list of problems. I figure I need this particular substance to keep me as healthy as possible and to help me cope with wildfire smoke. It's just that all of my money goes to medication/supplements and property taxes. I barely have enough money to pay for food, gasoline and utilities. Since I have been taking this product, it has gone up more than $3.50 per bottle. I just cannot keep up. I will probably decide to go without food one more day a week in order to buy this at some point - but I'm doing that already so much (more than twice a week and I'm already underweight!). I highly recommend this product, even at this price. I just can't believe they would suddenly mark it up so much

Great when paired with Resveratrol………..

Purportedly enhances absorption of resveratrol and it does seem to do that for me. I get a lot of energy and feel great when taken with a good diet

Feel good with it even I don't really know what it helps for

A friend who is a chemist recommended these for my leg cramps, taken together with vitamin C and Magnesium. Well, it didn't help my leg cramps but I feel generally much better and I even started to lose a little weight without diet. Don't know if it has anything to do with it, but I'll keep going for a while to see what else it can do for me

Good stuff, quite pricey.

I've been working on adding to my selection of supplements and vitamins to try to counteract my very, uh, unhealthy choice of foods. Sure, I'm a foodie, but I live with and cook for some pretty picky eaters who love their potatoes, pasta, and microwaved dinners. I can't 100% say with certainty that any improvements I got from this kind of quercetin were directly FROM it, as opposed to the tons of other pills I've been taking, but right around the time I started taking these, quite a few of my niggling little health issues stopped. However, from OTHER people I've known to take these regularly, they swear by it, saying it fixed allergies, COPD, heart problems, skin problems, etc., or saying they've pretty much stopped getting sick, on top of them finding them to kick in pretty quickly, as per the "bio-available" part of the description on the bottle. (One thing I need to mention is that it's better to check out the manufacturer's website, (cough cough) for pricing reasons (cough cough).) Anyway, I definitely join my buds in agreeing that quercetin is another one of those supplements that people should really look into more often, as opposed to just taking whatever comes in those generic multivitamins. There's nothing wrong with branching out a little, trying something new to maybe solve some issues without having to spend hundreds/thousands at a doctor

Wow, who knew somthing so simple could be so life changing

I've been trying every possible combination for vitamins, herbs, tonics and anything thing else to give me a mental and physical boost. I randomly bought a different product that had a few different ingredients. And it worked, the life of fog faded, my lack of motivation was replaced with what I would assume is just everyone else's ability to move around this planet. Since the other product was a little pricey, I broke it down the ingredients and tried all of them separately. I just happened to buy this one. After some time of trying different combinations of the ingredients I found that just this 1 herb was were I was getting results. I then found this was a little spendy so I try some other brands. Turns out only 1 out of the 10 or so other brands work as well and it was just as expensive. Fyi, it was "Huai Hua Mi (Sophora Japonica) liquid" on Amazon. All other brand had NO affect, even at a very high doses. So yeah, whatever your reasons for reading this review, if its in stock, BUY IT NOW! I take 3-5 at a time a couple of times a day, but I pretty much take excess of most things so don't use me as a guide unless you do the same thing. You know who you are...lo
