Key Benefits
-
Supports immune function and natural histamine balance.
-
Helps regulate inflammation and oxidative stress.
-
Promotes respiratory health and seasonal wellness.
Quercetin-Ascorbate Powder combines quercetin and vitamin C, two powerful antioxidants that work together to support immune health, inflammation balance, and overall wellbeing. Each serving provides 500 mg of quercetin and 500 mg of vitamin C (ascorbic acid) in an easy-to-mix powder.
Quercetin is a flavonoid found in plants that helps regulate mast cells and basophils, the immune cells involved in histamine release and inflammation. Vitamin C enhances quercetin’s absorption while also supporting collagen production, iron absorption, and oxidative stress defence. Together, they help the body respond to seasonal respiratory challenges and everyday stressors.
This formula is designed for optimal bioavailability, providing a natural way to support immune resilience, antioxidant protection, and a healthy inflammatory response.
