## Description

desertcart.com: Source Naturals Activated Quercetin, Bioflavanoid Complex* - 200 Capsules | For Seasonal & Immune Support* : Health & Household

Review: A lifesaver for histamine intolerance - I have within the past year been diagnosed with a histamine intolerance, which finally explains my bouts of uncontrollable drowsiness (to the point where if I stay awake I almost start blacking out) and/or intense migraines that seem to come out of nowhere. I have been able to avoid these symptoms by carefully monitoring what I eat, and especially avoiding slow-cooked meats and dried fruits. However, occasionally something will set the symptoms off unexpectedly. This is where quercetin comes in. When I feel the drowsiness start to come on, I take anywhere from four to ten of these tablets, and it wards off the symptoms. After an hour or two I feel normal again. As an experiment, I tried taking this quercetin with a few servings of dried fruit. Eating from this exact same bag of fruit previously made me so drowsy I was down for the evening and the whole next day, unable to think clearly or move much, almost unable to see or balance, until I was able to take quercetin. I tried eating the fruit with eight or so of these quercetin tablets, and I experienced only very mild sleepiness. This confirmed to me that they do work for fending off the histamine symptoms. This benefit was unexpected; I originally bought this product because it's supposed to have solid health benefits. I can't say for sure whether it's working in that regard, but overall I'm extremely glad to have this product and I plan to keep it in my supplement arsenal indefinitely. I believe that anyone with histamine intolerance should try quercetin as a possible remedy.
Review: Pills - Easy to take. Seems to be good quality

### ⭐⭐⭐⭐⭐ A lifesaver for histamine intolerance

### ⭐⭐⭐⭐⭐ Pills
*by L***O on May 14, 2026*

Easy to take. Seems to be good quality

### ⭐⭐⭐⭐⭐ Life Saving
*by C***D on July 17, 2022*

Calling it life saving is hyperbole on my part but these little pills have offered me a miracle. I recently developed an immune disorder that leaves my muscles weak and in pain even if I don't even tax them. I was visiting my boyfriend recently and was struggling to even take a step up a single stair. A whole flight of stares would be out of the question. His mother offered me some of these and after I did a quick check to make sure it wouldn't interfere with my medication I took it. The next day I was able to climb steps with no trouble! My pain was gone, the swelling in my joints eased. It was astonishing. I plan on telling everyone I know about these little miracle workers. I'm not sure of all the science behind it but take my anecdotal evidence: They work!
