🧪 Formulation Notes

Ultra Potent-C Chewable is a proprietary formulation designed to be gentle on the stomach and well-tolerated at high doses. Our vitamin C has been scientifically developed to enhance the absorption of vitamin C by while blood cells, a vital part of your immune system, when compared to ascorbic acid. One great-tasting tablet provides the same amount of vitamin C found in four oranges.
