How It Works
How It Works
Vitamin C supports immune function and acts as an antioxidant to protect against free radicals. Quercetin bioflavonoids enhance vitamin C's activity in your body and provide additional antioxidant benefits. Together, they work more effectively than either ingredient alone.
Who It's For
Adults looking for comprehensive immune support, especially during seasonal challenges. Ideal for those who want the enhanced benefits of vitamin C with bioflavonoids rather than basic ascorbic acid. Perfect for anyone focused on maintaining healthy collagen production for joints, skin, and connective tissue.
Who It's Not For
Not suitable for children under 18 or those with known allergies to vitamin C or quercetin. Consult your healthcare practitioner if you're taking blood-thinning medications.
