If you like to add Vitamin C to your juice, shakes, or smoothies, this is the product you need. And because it is buffered with mineral ascorbates it keeps the acidity down, which makes it easier to tolerate.

The bioflavonoids work synergistically with the Vitamin C and will also be helpful during allergy season. If you get severe allergies, then use the high dose quercetin as well.
