What is the diference between Magnesium Ascorbate and Sodium Ascorbate? Which one is better?

Ingredients. These are primarily intended for slightly different conditions so it depends on what you are trying to accomplish. One is not 'better' than the other. Ask your provider or read about the concern you have. MA can be helpful for digestion issues. Some say SA can help cell function to improve concerns like malignancy. Neither in moderation is likely to be dangerous.
