Review: Currently taking my headaches away - Unlike many other reviewers, I do not take these for asthma or seasonal allergies. I currently take them for headaches, what I call migraine headaches and what my doctor calls tension headaches (we disagree). I've had problems with headaches for quite a few years now and have always "carefully" used Advil, which usually helped but didn't completely take the headache away. More recently I've been having more headaches and they are powerful bad ones, pain on both sides of the head, tension in the neck and upper back, lasting about 24 hours (+/- 4 hours), and usually include some stomach discomfort such as nausea and lack of appetite. In the past I blamed many of my headaches on caffeine (too much or not enough) but I found those headaches usually went away after a couple hours of sleep. The headaches I get not do not usually diminish with sleep and if I don't take anything for them, the pain prevents me from sleeping. In the past year I discovered that I was getting headaches every time I consumed pepper - red pepper, chili pepper, cayenne, tabasco, jalapenos, and even red or green bell pepper. Even the tiniest amounts such as contamination would cause one of my severe "migraine" headaches. This has been debilitating as I don't cook much and pepper is in many prepared and restaurant foods, often hidden in ingredients such as "spices" or "natural flavorings", or even just getting in stuff through contamination (same grill, same oil, etc). I grew up heating hot peppers all the time and I love eating at Chipotle's so it's been hugely disappointing to develop this problem. I've found a few other reports online of the same, but it does seem to be a very unusual problem. Just recently I've discovered that if I take one or two of these as soon as I feel (or suspect) a headache, it seems to stop the headache completely. I do get dry mouth and sometimes urinate a little more than usual as quercetin appears to be a diuretic. Quercetin is also a vasodilator (relaxes or "dilates" blood vessels) as it seems to increase nitric oxide in the blood. Vasodilators are generally considered the cause of migraines, so it seems odd that one vasodilator (peppers) will cause me a headache and another one (quercetin) will take it away. Likely the real mechanisms involved here are more complicated than that. I am pleased though to find that quercetin has this affect as Advil seems to be causing me ulcer-like symptoms (nausea, bloating, acid reflux), even at doses as small as (2) pills every five to seven days. University of Maryland Medical Center's website says that Quercetin has been known to cause kidney damage at doses greater than 1g (or 1000mg) per day, though I cannot find any scientific study showing that. Each capsule contains 250mg so (4) of these in a day might put you in kidney damage zone. I'm really careful, only taking them when I need them, and I usually try to take only 2 or max 3 in a 24 hour period. I don't think kidney damage can be detected in its early stages so you do want to be careful with these. However, oddly enough, quercetin has also been shown to protect against kidney damage or to help people who have kidney disease, so the studies here seem to be conflicting. I suspect the headache reducing effect for me will be short lived, or else I'll end up finding out that it also had to do with something else I was doing at the same time as I have been trying other things like cutting out caffeine, exercising, and experimenting with a few other supplements. If I have any more definitive information to add, I'll try to remember to come back and update this review. For now, I am sure that quercetin does take my bad headaches away as I've proven it numerous times (but it does seem to work best if I catch it early). Review: CLOTS-BE-GONE - This review is for Quercitin-Bromelain/Nattokinase/Serrapeptase, because I take them all together, and don't know which individually had the great effect - BUT IF YOU EVER SUFFER CLOTS, READ THIS: I was struck by a 5500lb truck at 30mph and thrown 60ft and then run over with both axles, and suffered severe internal injuries. I ended up with a lot of raisin-sized clots in my anus. For some reason, they get stuck there, it's like a turn-around point in the venal-arterial system (like the hands/feet/head). First a doctor told me it was an emergency, and to come right in to have them surgically removed, so I did, and suffered the consequences of the poor physicians where I live (in many professional ways, it's 3rd world). She cut thru muscle and did a lot of damage, but did remove about 7 raisin sized clots. Then I noticed more (in the shower when you clean yourself), but since I couldn't go back to the doctor because of her wreckless neglect, I found these products in a desperate search to help myself - and guess what! THEY WORKED. I would take 2 of each (EMPTY STOMACH ONLY!), 6 total in the morning, and THEY DISSOLVED THE CLOTS IN DAYS! TRULY AMAZING! INCREDIBLE!!! SUPEREXPIALIDOCIOUS! The medical profession won't recognize this, but this stuff is MAGIC when it comes to blood clots - may have saved my life - since clots can do a lot of damage if they get stuck in your head or heart. Anyway, this is just incredible stuff for blood clots. Can't thank this business enough for a product that works like a charm. I am so thankful for this product. I feel like donating to the business out of gratuity! Now and then, I take them just for the heck of it, and have not had any more problems with blood clots. I really can't be more thankful - I would have had to have flown 1000 miles to deal with this any other way. IT IS MAGIC FOR BLOOD CLOTS!!!

Hehe - MAGIC! ### ⭐⭐⭐⭐⭐ Won't Raise Your Blood Pressure *by M***. on November 6, 2013* Better than Pseudoephedrine. Works well with my blood pressure medication and I can take as much as I need with hardly any side effect. When my sinus was infected, I used this in larger quatities, about 4 to 6 per dose, twice daily, and I got some minor leg cramps, but with only one of two a day to treat my day-to-day regular sinus problems, I have no side effects whatsoever. Bromelain is all natrual and is found in Pineapple, the only bromiliad plant that humans can consume with impunity, and is found in meat tenderizers and marinates. It helps to loosen mucous and break it down. Quercetin shuts down the mucous generator, which is something most mucous medications can't do. I use this in conjunction with Fexofenedrine and it works pretty well to control my allergies here in Michigan. Many people that live here have the "Michigan Sinus" which is infamous here in Michigan which my doctor told me about. He approved of this regimine with the Quercetin and Bromelain when taken with my anti-allergen of choice. In my opinion, if you have high blood pressure, this is a cheaper, safer alternative than pseudoephedrine. ## Frequently Bought Together - Doctor's Best Quercetin Bromelain, Immunity Support Capsule, Heart, Joint & Healthy Respiratory System, Non-GMO, Vegan, Gluten Free, Soy Free,180 VC - Doctors BEST High Absorption Magnesium Lysinate Glycinate 100% Chelated, Muscle Relaxation & Sleep Support, Non-GMO, Gluten Free, Soy Free, Vegan, 100% Chelated 240 Tablets - Doctor's Best High Absorption CoQ10 with BioPerine, Gluten Free, Naturally Fermented, Heart Health, Energy Production, 100 mg, 120 Count --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/3867270-quercetin-bromelain-immunity-support-capsule-heart-joint-and-healthy-respiratory](https://www.desertcart.vu/products/3867270-quercetin-bromelain-immunity-support-capsule-heart-joint-and-healthy-respiratory) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-06-05*
