Vitamin C Powder provides vitamin C in the bioavailable form of magnesium ascorbate. Magnesium ascorbate is far less acidic than the ascorbic acid form of vitamin C whilst also providing magnesium. Further development work and improvements in our manufacturing techniques have enabled us to provide magnesium ascorbate powder with improved solubility whilst still maintaining a neutral pH. This improved form of Vitamin C powder should be suitable for even those individuals with very sensitive digestive systems. Please note that this new Vitamin C powder has a slightly different, less metallic taste to the previous batches due to this change.
