NutriBiotic Calcium Ascorbate is manufactured by dissolving pharmaceutical grade ascorbic acid in a solution with calcium carbonate (mined from the earth). NutriBiotic Calcium Ascorbate is a fully reacted compound and not a dry mix of calcium carbonate and ascorbic acid.

The manufacturing procedure for NutriBiotic Pharmaceutical Grade Ascorbic Acid involves 15 steps. Vegetable starch is broken down into simple sugar (D-Glucose) by the action of heat and enzymes. The D-Glucose is converted into D-Sorbitol through hydrogenation. The D-Sorbitol is then converted into L-Sorbose through fermentation. L-Sorbose is combined with acid at low temperatures. This product is then oxidized with a catalyst, acidified, washed, and dried forming L-Gluconic Acid. The L-Gluconic Acid is treated with hydrochloric acid forming crude ascorbic acid. The last involves filtering, purifying, and milling the crude ascorbic acid into a fine crystalline powder.

This is our most alkaline (buffered) form of vitamin C. Because the 10% calcium content of this product is fully reacted with and bound to the vitamin C component, there is not hint of tartness. It provides significant levels of calcium with vitamin C in a gentle, alkaline form. Helpful for those bothered by more acidic forms or people desiring a calcium boost from their vitamin C.
