You do not need to drink apple cider vinegar every day, and it is not suitable for everyone. Daily use only makes sense if it is well tolerated and your personal risk factors are considered. People with reflux, gastritis, ulcers, or dental enamel sensitivity may feel worse with daily intake. Also, a “daily = more benefit” mindset can push people toward higher doses. A healthier perspective is treating vinegar as a small supportive habit while the main drivers remain diet quality, movement, sleep, and stress management. If it causes symptoms, daily use is not appropriate.
