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.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 diarrhoea 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.Ingredients:Serving Size; 1 teaspoon (4.7 g) Servings per container; 51Amount per serving:Vitamin C (as Ascorbic Acid); 2135 mgCalcium (as Calcium Carbonate); 405 mgMagnesium (as Magnesium Carbonate); 215 mgPotassium (as Potassium Carbonate); 90 mgOther ingredients: Cellulose.These nutrients are of the highest quality and purity obtainable, and do not contain preservatives, diluents, or artificial additives.
