Metagenics Ultra Potent-C® Powder is a proprietary, patented vitamin C formula that features a buffered delivery system designed to help prevent potential stomach upset associated with high vitamin C intake. Preliminary scientific research suggests that vitamin C in the form of Ultra Potent-C® may result in improved uptake of the vitamin by white blood cells when compared to regular ascorbic acid.
For best results, mix a rounded 1/4 teaspoon into four to six ounces of warm water and stir well. Take one time daily or as directed by your healthcare practitioner.
