Review: Histamine miracle - A life saver for my histamine issues. I take 2 and the brain fog and migraine lifts within 30mins! Review: GREAT for Mast Cell and MCS!!!! - I have been using this product for about 6 months to treat Mast Cell Disorder. I take 3-4 grams daily with 1-2grams of Vitamin C. It has been recommended to me by both my allergy/immunology specialist AND a renowned Mast Cell specialist. It has made a definite improvement in my symptoms. I can literally feel my mast cells stabilizing when I take them (fatigue reducing, coordination/focus improving, wheezing/air hunger improving) and those symptoms slowly return when I am nearing my next dose. My major triggers are airborne particles/smells caused by a mold exposure. I am very satisfied with the progress this has helped me make. Whenever I need a quality supplement, I reach for Jarrow. I also have MCS and have never reacted to any Jarrow products which says a lot about their quality. ## Features - Antioxidant Support: Quercetin, featured in this quercetin supplement, is a phenolic antioxidant found in onions, green leafy vegetables, and fruits such as apples and cherries - Cardiovascular Health: Quercetin supplements support cardiovascular health through antioxidant activity (1) - Flavonoids: Quercetin is an AllerTame flavonoid supplement, i.e., one that may support immune health (1) - Antioxidants Supplement: Take one of these Quercetin capsules per day with meals or as directed by your qualified healthcare professional ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0013OULOC | | Age Range Description | Adult | | Allergen Information | Allergen-Free | | Best Sellers Rank | #21,140 in Health & Household ( See Top 100 in Health & Household ) #12 in Quercetin Antioxidant Supplements #1,668 in Sales & Deals #2,008 in Diet & Sports Nutrition | | Brand | Jarrow Formulas | | Brand Name | Jarrow Formulas | | Color | No Color | | Customer Reviews | 4.7 out of 5 stars 4,100 Reviews | | Diet Type | Gluten Free | | Dosage Form | Capsule | | Flavor | Unflavored | | Global Trade Identification Number | 00790011140528 | | Item Dimensions | 6 x 5 x 4 inches | | Item Form | Capsule | | Item Weight | 3.4 ounces | | Manufacturer | Jarrow Formulas | | Manufacturer Part Number | QUE200 | | Material Features | GMO Free | | Model Name | Quercetin | | Model Number | QUE200 | | Number of Items | 1 | | Primary Supplement Type | Quercetin | | Product Benefits | Antioxidant | | Recommended Uses For Product | Cardiovascular Health, Immune Support | | Special Ingredients | Quercetin | | Specific Uses For Product | Nerve | | UPC | 767644127493 798411182575 885204227732 305251216959 790011140528 | | Unit Count | 200 Count | ## Product Details - **Brand:** Jarrow Formulas - **Diet Type:** Gluten Free - **Flavor:** Unflavored - **Item Form:** Capsule - **Item Weight:** 3.4 ounces - **Item dimensions L x W x H:** 6 x 5 x 4 inches - **Primary Supplement Type:** Quercetin - **Product Benefits:** Antioxidant - **Special Ingredients:** Quercetin - **Unit Count:** 200 Count ## Images ![Jarrow Quercetin 500mg Capsules for Cardiovascular & Immune Health, 200ct - Image 1](https://m.media-amazon.com/images/I/71HQr1FA2SL.jpg) ## Available Options This product comes in different **Size, Flavor** options. ## Questions & Answers **Q: I bought this a couple of times this year for $18/bottle, and now the price is up to $32. Any explanation?** A: I too was purchasing at around $18/bottle and now it's gone up, not to $32 but $24 which is still a 35% increase. I understand things go up and down but that's quite a difference... I will be looking at other sources. **Q: Where is this product made...in the USA or where?** A: Product of USA on ad picture **Q: Which form of querceten is this product? ( dihydrate, glycosides, aglycone, or rutinoside?)** A: I spoke to Jarrow, per their rep it is anhydrous form. So it is about 10% more quercetin per gram than dihydrate because two H2O molecules have been removed. **Q: What is the source of the quercetin?** A: I inquired about this in December and this is Jarrow's response: "Jarrow Quercetin is sourced from the Japonica Sophora Tree, and is the anhydrous form." ## Customer Reviews ### ⭐⭐⭐⭐⭐ Histamine miracle *by L***E on June 25, 2026* A life saver for my histamine issues.
