The USANA Difference
Vitamin C is one hardworking nutrient and contributes to the maintenance of good health throughout the body. USANA’s Poly C™ contains an advanced formula with a unique blend of mineral ascorbates that make the vitamin C available in the body’s blood stream for a prolonged period of time. It is also formulated to complement USANA’s CellSentials®, providing extra vitamin C when you really need it. Better yet, it contains citrus bioflavonoids, rutin, and quercetin so you can have the combined benefits of vitamin C and bioflavonoids.

Health Benefits

  • Vitamin C carries dual importance as the body’s premier water-soluble antioxidant and as a coenzyme essential for the synthesis and health of connective tissues in the skin and throughout the body
  • Supports development and maintenance of bones, cartilage, teeth, and gums
  • Contains mineral ascorbates to provide superior bioavailability and prolonged vitamin C activity while also reducing the potential of stomach irritation.
