Yes, you can drink apple cider vinegar (ACV), but it should always be diluted with water to avoid harmful effects. Drinking undiluted ACV can irritate the esophagus, erode tooth enamel, cause throat burns, and lead to digestive discomfort. A safe amount to consume is typically 1 to 2 tablespoons mixed in a glass of water per day. It is also advised to drink it with or after meals rather than on an empty stomach to reduce discomfort. Using a straw and rinsing your mouth afterward can help protect your teeth from acid damage. People with certain conditions like acid reflux, low potassium levels, kidney disease, or those on certain medications should consult a doctor before using ACV regularly. Consuming ACV in food, such as salad dressings or marinades, is generally safer and less likely to cause side effects.
