Manufacturing Procedure for Natural Source Vitamin C The manufacturing procedure for ascorbic acid (natural source vitamin C) involves a 15 step process. Vegetable starch is reduced to a simple sugar (D-glucose) which is then converted to pure ascorbic acid.

Our Promise and Guarantee We use only 100% pure pharmaceutical grade ascorbic acid (USP-FCC) which contains no corn residue, plant antigens or protein impurities. Persons allergic to corn or yeast, or those who have difficulty with regular vitamin C, can use this product. The vitamin C in this product undergoes 900 analytical tests and quality checks to insure you the highest purity and consistent raw material obtainable. The minerals in this formula are blended with ascorbic acid, forming mineral ascorbates in a solution. All the minerals are mined from the earth.
