It has drawn attention for two reasons that sit close together: it is a capable antioxidant, and it influences the inflammatory response.\u003c\/p\u003e\n\u003cp\u003eAs an antioxidant it supports immune function by limiting free radical damage to cells. On the inflammatory side, quercetin is a mast cell stabiliser — it moderates the release of histamine, which is why it appears so often in seasonal allergy protocols alongside vitamin C. The cardiovascular claims on the Canadian licence are unusually specific: it may help reduce blood pressure, enhance capillary resistance, reduce capillary fragility, reduce blood lipids, expand the coronary artery and increase coronary blood flow.\u003c\/p\u003e\n\u003cp\u003e500 mg per vegetable capsule, in 60 and 120 capsule bottles. Dosing is one to two capsules once daily. Prairie Naturals has been formulating in British Columbia since 1993, without artificial colours, artificial sweeteners or unnecessary fillers.\u003c\/p\u003e\n\u003ch3\u003eWho Prairie Naturals Quercetin 500mg Is For\u003c\/h3\u003e\n\u003cp\u003eThis suits people supporting immune function, anyone dealing with seasonal allergic symptoms who wants something alongside or instead of an antihistamine, and people building a cardiovascular routine. It also pairs conventionally with vitamin C, which is thought to support quercetin's activity.\u003c\/p\u003e\n\u003cp\u003eThe label sets a 12-week limit before consulting a practitioner, which is worth respecting rather than treating as boilerplate. Quercetin can interact with several medication classes, particularly those metabolised by the liver, and with blood pressure medication given the licensed claims. Anyone pregnant or breastfeeding should consult first.\u003c\/p\u003e\n\u003ch2\u003ePrairie Naturals Quercetin 500mg Features and Benefits\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e500mg Quercetin Per Capsule\u003c\/strong\u003e — A substantial single-active dose in a vegetable capsule.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBioflavonoid Antioxidant\u003c\/strong\u003e — Helps prevent cell damage from free radicals and supports healthy immunity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupports a Healthy Inflammatory Response\u003c\/strong\u003e — Quercetin moderates histamine release, which is why it appears in allergy protocols.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCardiovascular Support\u003c\/strong\u003e — Licensed claims include capillary resistance, blood lipids and coronary blood flow.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMay Help Reduce Blood Pressure\u003c\/strong\u003e — One of the specific claims on the Canadian product licence.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePairs With Vitamin C\u003c\/strong\u003e — Commonly combined, as vitamin C is thought to support quercetin's activity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo Sizes\u003c\/strong\u003e — 60 and 120 vegetable capsules.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv class=\"faq-section\" id=\"faq-prairie-naturals-quercetin-500mg\"\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eProduct Information\u003c\/h3\u003e\n\u003cdetails\u003e\u003csummary\u003e➕ What is Prairie Naturals Quercetin?\u003c\/summary\u003e\u003cdiv style=\"padding-left:25px; margin-top:5px; padding-bottom:10px;\"\u003eA single-active supplement providing 500 mg of quercetin per vegetable capsule, in 60 and 120 capsule bottles.\u003c\/div\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003e➕ How much do I take?\u003c\/summary\u003e\u003cdiv style=\"padding-left:25px; margin-top:5px; padding-bottom:10px;\"\u003eOne to two vegetable capsules once per day.\u003c\/div\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003e➕ Which size should I buy?\u003c\/summary\u003e\u003cdiv style=\"padding-left:25px; margin-top:5px; padding-bottom:10px;\"\u003eAt one capsule daily, 60 capsules is two months and 120 is four.
