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.

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.

I'll be honest—I wasn't expecting much when I started taking Life Extension's Bio-Quercetin. I'd heard the hype about quercetin helping with histamine issues, but after years of trying different supplements with mixed results, I was sceptical. I have to say I’m surprised! I've been dealing with hayfever that makes spring utterly miserable, plus these annoying heat hives that pop up whenever the temperature climbs (my doctor suspects MCAS but we're still working through that diagnosis maze). Within about a week of taking these capsules daily, I noticed my hayfever symptoms were significantly better. The heat hives? They're not completely gone, but they're nowhere near as angry and frequent as before. But here's the truly unexpected bonus: my stomach. I have a laundry list of digestive issues, and certain foods just wreak havoc on my stomach. I noticed after a few weeks that my post-meal stomach pain and bloating were noticeably better, especially after eating foods that normally trigger a reaction. I wasn't taking it for that purpose, but I'll absolutely take that win! It’s helped so much I’ve been able to stop taking Nexium every day! The capsules themselves are refreshingly small and easy to swallow—a genuine relief when you're already taking multiple medications and supplements daily. No weird aftertaste, no drama getting them down. If you're dealing with hayfever, suspected mast cell issues, or just general inflammation, this is absolutely worth a try. My body's giving it two enthusiastic thumbs up!
