ACV For Health Keto are dietary supplements that combine the benefits of the ketogenic diet and apple cider vinegar (ACV) into a convenient and tasty form of gummy. The ketogenic diet is a high-fat, low-carb diet that forces the body to burn fat for fuel instead of carbohydrates. ACV is made by fermenting apples and contains acetic acid, which has been linked to various health benefits such as improved digestion, weight loss, and lower blood sugar levels.
