Question: is it safe to drink apple cider vinegar by itself?
Answer: Apple Cider Vinegar Uses and Dosage There's a lot of acid in it, so drinking vinegar straight isn't recommended. It can cause problems, like eroding the enamel of your teeth, if you get too much. If you're looking to use it for health reasons, most people say to add 1 to 2 tablespoons to water or tea.
