Quercetin (bioflavonoids) "My NMD suggested Quercetin to me at a dose of 500mg 3 times day. I only have taken 500mg once day, this stuff gave me bad side effects of mild dizziness, mild nausea. difficulty sleeping. I am sensitive to many supplements, so this is not a condemnation of Quercetin for all... but beware,,, this stuff CAN cause side effects and make you feel lousy!"

Quercetin (bioflavonoids) "It took a while for me to put it together but this supplement caused pretty significant heart palpitations and racing heart. The brand I used was by Toniq if that has an effect. I'm sensitive to caffeine in that way but I do not use caffeine. I didn't use long enough to see a benefit. I figured the connection to heart palpitations after about 10 days. Sorry it took so long."

Quercetin (bioflavonoids) "It has taken me much too long to realize I had 7 side effects, palpitations, rise in blood pressure, pounding in my ears, nervousness, heavy legs, dizziness, and blurred vision. I am struggling here and I don't know how to get relief now. I will never take it again. I am really sensitive to all kinds of supplements and pills."

Quercetin (bioflavonoids) "My family started taking a once daily, 800 mg quercetin/165 mg bromelain capsule, along with 1000 mg vit c (lypospheric) sachet, and a zinc powder as a prophylactic. After a couple of weeks, it became apparent that our energy levels were reduced, and we became listless, and dare is say, mildly depressed, having no inclination to do anything during the holidays. My wife also experienced headaches. We stopped the Quercetin, and within a few days, energy levels seemed restored, and we feel a great deal more energetic. This may be unrelated to Quercetin, but i felt it worth mentioning, so you may monitor your own feelings."

Quercetin (bioflavonoids) "Started taking this after hearing about it from an internet guru. I have a slow heart rate to begin with. This stuff slowed it down in the 40's. I believe many experience dizziness from either bradycardia or tachycardia caused by this supplement. I also had problems sleeping as well as the leg pain. Literally every side effect listed. Don't use this. There are beneficial flavanoids in fruit that won't cause all of this mess."

Quercetin (bioflavonoids) "Taking this for my seasonal allergies and histamine tolerance combined with Zinc and C. It opens my nose right up gives me energy and increased my mood. I also feel much better, focused and no brain fog and can tolerate more foods. However, this makes you poop after 30 minutes of taking one pill. Gives cramps, bloating, and gas. Honestly it’s too bad since it is helping with other symptoms, inflammation and food intolerance. I have to take it before bed since taking during the day is impossible with those GI issues. Too bad."

Quercetin (bioflavonoids) "I had been having problems with always feeling cold, especially my feet. I always had to wear a hoodie or a sweater to keep warm and sleep with a heated blanket. 74 degrees room temperature, and I was freezing. I started taking Quercetin and I am no longer cold. My energy level is up—no more brain fog. Pain levels have decreased. I have had no side effects from taking it."

Rutin (bioflavonoids) "I began taking Rutin after reading that it helps activate brown fat to burn the more harmful white fat (in the belly and elsewhere). For many years I have taken Ester-C, 500mg, daily, to which I have added the 500mg Rutin complex. Because I did not heavily research this OTC supplement beforehand I did not know it had other uses. By coincidence I had suffered my first bought with high blood pressure beforehand and I had also suffered for three weeks with another middle-aged first: a hemorrhoid. After taking Rutin for 10 days I had no more high blood pressure episodes, no more hemorrhoid discomfort, less knee pain and fewer asthma symptoms. These benefits were unexpected. The downside? I now have 4 weeks of daily headaches and blurred vision."

Quercetin (bioflavonoids) "I have been taking a range of supplements during the Covid episode (vitamins B, C, D, Magnesium, Zinc, Quercetin, Cosamin, Qunol, ARED-2 and Turmeric) plus two prescription meds for high blood pressure. Sometimes I would eat something late, but always took all my pills just before bed. Usually my sleep was bad and I would awaken a lot with nausea and digestive discomfort. Sometimes more, sometimes less. Recently I thought the pills might be causing the problems, so I switched to taking them at noon. My sleep abruptly became long, sound and comfortable -- but now I began feeling ill and nauseated in late afternoon and diarrhea into the evening. So then I tried only one of the supplements per day. I discovered that it is Quercetin 800mg with Bromelain that does this to me. Checking Quercetin side effects online, I may have some of them too -- nighttime skin itching, leg and ankle swelling, leg pains and blood pressure increases. Still testing those."

Quercetin (bioflavonoids) "In combination with bromelain and vitamin C, I noticed that quercetin made a positive difference in ease of breathing but it took some time to be effective. It’s been a year since I took it but now have breathing issue a few weeks after Covid so will try again."

Quercetin (bioflavonoids) "I was put on a popular natural antihistamine for sinus allergies and other symptoms of higher histamine levels as I'm entering menopause. The product contains quercetin as a main ingredient. After three days of use, I'm feeling very sick. On and off upset stomach, woozy head/headache, greater fatigue, and overall feel ill all over. I'm fairly reactive to things and have a sensitive stomach. I'm stopping the supplement and going back to my 1/2 Benadryl at bedtime."

Quercetin (bioflavonoids) "I took 500 mg for first time this morning, for anti inflammatory properties. Also took with my normal probiotics, and an NAC that I've been taking for immune support. I was hoping for energy boost, and skin benefits as well. This definitely made my heart race a bit, but it didn't last too long. My mother-in-law loves this stuff. Too soon to tell if it's beneficial for me or not. Would like to give it a go again."

Quercetin (bioflavonoids) "Started taking an immunity boosting supplement today with 200 mg Quercetin. After an hour, had nausea to the extent that I thought I would lose my breakfast but it passed. Will try again tomorrow. Everything except Q I’ve taken before so I’m suspicious."
