A unique, freeze-dried Vitamin-C, always whole-food sourced, ensuring potency and high quality. The bioavailability of Power C is at its best because of its preservation in a raw, natural state. Since no heat is involved in our manufacturing process, all enzymes are left perfectly intact, including valuable antioxidants, fiber, bioflavonoids and polyphenols. The immune-supporting antioxidant quercetin is also readily available in this Power C formula. Since it is a complete Vitamin C complex, there is no need for thousands of milligrams of ascorbic acid, a cheaper synthetic that is more difficult for the body to absorb.
