Ascorbic Acid is another name for Vitamin C, which is a popular antioxidant and one of the most widely used vitamins in the world. This product offers 100% purity and is more convenient to use than many Vitamin C Powders, as the fine Powder dissolves more readily in liquids than regular crystalline ascorbic acid. This highly concentrated Powder provides over 1 gram of Vitamin C per 1/4 teaspoon.
