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.
About This Product
Each tablet of Natural Factors C Extra 500 mg + Quercetin Bioflavonoids 500 mg holds 500 mg of vitamin C and 500 mg of quercetin, an even one-to-one match. For normal development and maintenance of bones, cartilage, teeth and gums.
What are quercetin bioflavonoids?
Bioflavonoids are a broad class of coloured compounds that plants produce, and quercetin is among the most widespread of them. It occurs in the skins of apples and red onions, in capers, kale and buckwheat. Vitamin C, supplied here as ascorbic acid, is a water-soluble vitamin that the human body cannot make. The two share many of the same food sources, which is one reason they are so often combined in supplements.
