Ultra Potent-C® 1000

Ultra Potent-C® 1000


Ultra Potent-C® 1000 is a proprietary, patented vitamin C formula that features a buffered delivery system designed to help prevent the potential stomach upset sometimes associated with high vitamin C intake. Ultra Potent-C 1000 may help support healthy immune function and is a good source of antioxidants from vitamin C. 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.*
