NutriBiotic Ascorbic Acid, Crystalline Powder 100% Pure Natural Source Vitamin C Pharmaceutical Grade pH 2.1 Hypo-Allergenic A Dietary Supplement NutriBiotic Ascorbic Acid has the highest solubility of all vitamin C powders which makes it the easiest to mix into water or any beverage. The manufacturing procedure for NutriBiotic All-Natural Source Ascorbic Acid involves 15 steps. Steps 1 thru 9 (Starch Hydrolysis): Vegetable starch is broken down into simple sugar (D-Glucose) by the action of heat and enzymes. Step 10 (Hydrogenation): D-Glucose is converted into D-Sorbitol. Step 11 (Fermentation): D Sorbitol is converted into L-Sorbose. Step 12 (Acetonation): L-Sorbose is combined with an acid at low temperatures. Step 13 (Oxidation): The product is then oxidized with a catalyst, acidified, washed and dried forming L-Gluconic Acid. Step 14 (Hydrolysis): L-Gluconic Acid is treated with hydrochloric acid forming crude ascorbic acid. Step 15 (Recrystallization): The crude ascorbic acid is filtered, purified and milled into a fine crystalline powder. SUGGESTED USE: As a dietary supplement, mix 1/4 teaspoon or more in a glass of juice or water. Take with or without meals. INGREDIENTS: High Solubility Ascorbic Acid USP-FCC** (C6H8O6).
