My grandmother believed that Apple Cider Vinegar helped EVERYTHING! But I do believe that A tablespoon daily with your morning routine helps blood circulation, which in turn helps bloating.
Apple cider vinegar kills Candida which is in the bowels (that causes bloating). It also improves digestion through the Mother in the ACV which can relieve bloating as well.
If you are experiencing gas and bloating it may be because your body is missing, or is in short supply of some essential digestive enzymes. Apple cider vinegar helps by replacing the digestive enzymes that you may be lacking.
