The old saying, “an apple a day keeps the doctor away,” seems to have evolved. Now, many people believe that a teaspoon of apple cider vinegar each day can significantly boost their health.

Apple cider vinegar is made from fermented apple juice, which produces alcohol and acetic acid during the process. Some kidney stone formers believe that the acetic acid in apple cider vinegar can dissolve these stones.

However, research suggests that dietary acids, including apple cider vinegar, lack the necessary concentration or mechanism to actually dissolve kidney stones.
