Buffered Vitamin C Powder contains high-purity ascorbic acid buffered with carbonates of potassium, calcium and magnesium. Buffered C has an acid-alkaline buffering action that can help control the increased acidity often associated with allergic reactions.* Developed by Stephen A. Levine, Ph.D. Cassava, or Manihot esculenta, is a bushy South American shrub with long tuberous roots, which are traditionally eaten like potatoes. Cassava root starch serves as the starting material for a multi-step chemical process of manufacturing ascorbic acid. It is well tolerated by individuals unable to tolerate other sources of vitamin C.*Suggested Use: As a dietary supplement, 1 heaping teaspoon or more in 8 to 12 ounces of liquid between meals, or as directed by a healthcare practitioner. As with all vitamin C formulations, as one begins to achieve body saturation, “bowel tolerance” may be temporarily exceeded and diarrhea or loose stools may occur. As the high levels of vitamin C in the tissues become used up, the bowel symptoms should ease. Ideal for controlling acidity often associated with hypersensitivity reactions.*Serving Size 1 teaspoon (4.7 g) Servings per container 63 Amount per serving: Vitamin C (as Ascorbic Acid) 2135 mg Calcium (as Calcium Carbonate) 405 mg Magnesium (as Magnesium Carbonate) 215 mg Potassium (as Potassium Carbonate) 90 mg Other ingredients: Cellulose.These nutrients are of the highest quality and purity obtainable, and do not contain preservatives, diluents, or artificial additives.Variations in product color may occur.
