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.

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.
