Fermented Vitamin C from New Chapter is a new approach to immune support. Each serving delivers 250 mg vitamin C plus 15 mg of an immune support blend featuring European elderberry extract, organic eleuthero root and organic astragalus root. Why fermented vitamins? The fermentation process is thought to “unlock” the health-supporting potential of many common foods by breaking down nutrients within them, resulting in a product that is easier for the body to absorb.
