Top Ingredients: Quercetin and Vitamin C

Quercetin is a flavonoid found in many fruits and vegetables, recognized for its antioxidant and anti-inflammatory properties. In this formulation, it is stabilised for potency and efficacy. Vitamin C (as ascorbic acid) supports immune function and aids quercetin absorption. Together, they work synergistically to promote mast cell stability and histamine balance.* Both ingredients are well-studied in nutritional science.

Key Benefits of Quercetin with Vitamin C

Quercetin helps maintain normal mast cell integrity, which plays a role in the body's response to environmental stressors.* By promoting balanced histamine release, it helps maintain respiratory comfort and nasal health.* Vitamin C adds antioxidant protection and supports the immune system, making this combination a valuable part of a daily wellness routine.*

In addition to immune and respiratory support, quercetin contributes to cardiovascular health by supporting normal vascular stability and oxidative balance.* This formula is designed for those who prioritize high-quality, science-backed supplementation.

What Is ARG Quercetin 300?

Looking for a clean, science-backed supplement to support your immune system and seasonal wellness? ARG Quercetin 300 combines 300 mg of stabilised quercetin with vitamin C in a hypoallergenic, vegetarian capsule. This formula is thoughtfully crafted to promote mast cell integrity and balanced histamine levels.*

Who Might Benefit from This Supplement?

ARG Quercetin 300 is suitable for adults looking to support their immune system, particularly during seasonal challenges. It may be beneficial for individuals with occasional histamine sensitivity, as quercetin helps maintain normal histamine levels.* Those seeking a clean, allergen-free supplement will appreciate its gluten-free, dairy-free, soy-free, and vegan formulation. Always consult your healthcare practitioner before starting any new supplement regimen.

How to Choose the Right Quercetin Supplement

When selecting a quercetin supplement, consider the dosage form and purity. Quercetin is often poorly absorbed; pairing it with vitamin C can enhance bioavailability. Look for products that are third-party tested and free from common allergens. ARG Quercetin 300 meets these criteria with its hypoallergenic profile and high-quality ingredients. Also check for suitable serving size—this product provides 300 mg per capsule with a recommended serving of one capsule daily, or as directed by a practitioner.
