Yes, most healthy adults can drink apple cider vinegar (ACV) every day in small, diluted amounts, but there are important risks and limits to keep in mind.

✅ Potential benefits of daily ACV

Several small studies suggest that 1–2 tablespoons (15–30 mL) of ACV per day, taken with food or in water, may help with:

  • Blood sugar control – ACV can slightly lower fasting blood sugar and HbA1c in people with type 2 diabetes, especially when taken before meals.
  • Weight management – Acetic acid in ACV may increase feelings of fullness and reduce calorie intake, which can support modest weight loss over time.
  • Cholesterol and heart health – Some research shows small improvements in total cholesterol and LDL (“bad”) cholesterol with regular ACV use, especially in people with diabetes.
  • Digestion – ACV may support stomach acid production and gut balance, which some people find helpful for bloating or indigestion.

These effects are usually modest and work best alongside a healthy diet and lifestyle, not as a magic fix.

⚠️ Risks and side effects of daily use

Drinking ACV every day, especially in large amounts or undiluted, can cause problems:

  • Tooth enamel erosion – ACV is very acidic and can wear down tooth enamel over time, increasing the risk of cavities and sensitivity.
  • Throat and stomach irritation – The acid can irritate the esophagus and stomach lining, causing heartburn, nausea, or pain, especially if taken on an empty stomach or in high doses.
  • Low potassium (hypokalemia) – Long‑term, high‑dose ACV use has been linked to low potassium levels, which can cause muscle weakness, cramps, and even heart rhythm problems.
  • Bone health concerns – There’s a rare but serious case report of a woman who developed osteoporosis after drinking large amounts of ACV daily for years, likely due to low potassium and acid load on bones.
  • Drug interactions – ACV may interact with certain medications, including insulin, diuretics (“water pills”), and some heart drugs, so it’s important to check with a doctor if on regular meds.

🛑 When daily ACV is not a good idea

Daily ACV is not recommended for:

  • People with low potassium, osteoporosis, or kidney problems.
  • Those with acid reflux, GERD, or stomach ulcers, since the acid can make symptoms worse.
  • Anyone taking medications that affect potassium or blood sugar, without medical supervision.
  • Children, pregnant or breastfeeding women, unless approved by a healthcare provider.

✅ How to drink ACV safely every day

If you want to include ACV in your routine, most experts suggest:

  1. Dilute it well – Mix 1–2 tablespoons (15–30 mL) in a large glass of water (about 250 mL).
  1. Drink it with food – Take it before or with a meal to reduce stomach upset and help with blood sugar control.
  1. Use a straw and rinse – Drink through a straw and rinse your mouth with plain water afterward to protect your teeth.
  1. Limit the dose – Stick to 1–2 tablespoons per day; more is not better and increases risk.
  1. Take breaks – Some people choose to cycle ACV (e.g., 5 days on, 2 days off) to give the body a rest.

🩺 When to talk to a doctor

Before making ACV a daily habit, it’s wise to check with a doctor or dietitian if:

  • You have diabetes, kidney disease, or heart conditions.
  • You’re on any medications, especially insulin, diuretics, or digoxin.
  • You have a history of low potassium, osteoporosis, or digestive disorders.

Bottom line

For most healthy adults, drinking 1–2 tablespoons of diluted ACV per day is likely safe and may offer small benefits for blood sugar and weight, but it’s not a miracle cure. The key is moderation, proper dilution, and listening to your body; if you notice tooth sensitivity, stomach pain, or other issues, it’s best to stop or cut back.
