Yes, apple cider vinegar is generally safe for daily long-term use when taken at recommended doses, though there are some caveats to be aware of. The 500mg to 1,000mg daily range used in most studies appears safe for ongoing use spanning several months. However, taking excessively high doses or drinking undiluted liquid vinegar daily can cause problems like tooth enamel erosion, throat irritation, and low potassium levels over time. Capsules like Nutrivolv’s 720mg formulation bypass most of these risks because you’re not exposing your teeth and throat to acid. That said, it’s worth taking occasional breaks. Consider cycling it with a week off every three months to give your system a rest. If you have chronic kidney disease or very low potassium levels, daily use isn’t recommended without medical supervision. It’s not suitable during pregnancy or breastfeeding due to limited safety data. Most healthy adults can take it daily indefinitely at normal doses, but if you’re using it for weight loss and you’ve achieved your goal, you might not need to continue long-term.
