How It Works
How It Works
Vitamin C supports your immune system while helping form collagen for healthy connective tissues. Quercetin bioflavonoids enhance vitamin C absorption and activity in your body, making this combination more effective than vitamin C alone.
Who It's For
Adults looking for immune support with enhanced absorption. Anyone wanting the collagen-supporting benefits of vitamin C. People who prefer the convenience of once-daily capsules over multiple doses.
Who It's Not For
Not suitable for children without healthcare practitioner guidance. Those with known sensitivities to citrus bioflavonoids should consult their healthcare provider first.
About This Product
Natural Factors C Extra 500 mg + Quercetin Bioflavonoids 250 mg brings together 500 mg of vitamin C and 250 mg of quercetin in an easy swallow capsule. For normal development and maintenance of bones, cartilage, teeth and gums.
What is C Extra + Quercetin?
This formula joins a vitamin with a bioflavonoid. The vitamin C is ascorbic acid, a water-soluble nutrient that people must get from food or supplements. Quercetin is one of the flavonoids, a class of plant compounds that often turn up alongside vitamin C in fruits and vegetables such as onions, apples and citrus. The quercetin used here is taken from the buds of Sophora japonica, the Japanese pagoda tree.

- 500 mg vitamin C (ascorbic acid) per capsule
- 250 mg quercetin from Sophora japonica bud
- 60 or 90 easy swallow capsules

Why vitamin C and quercetin together?
The two are frequently bought as a pair. Putting both in one capsule means a single product in place of two bottles, at two parts vitamin C to one part quercetin.
