How Much Apple Cider Vinegar Should You Drink Per Day?

Apple cider vinegar (ACV) has gained popularity as a natural health remedy, but its use requires careful consideration of dosage and safety. Clinical evidence supporting many of its purported benefits—such as weight loss, blood sugar regulation, or cholesterol improvement—remains limited and largely inconclusive. Most human studies have used doses ranging from 15 to 30 mL (approximately 1 to 2 tablespoons) per day, typically diluted in at least 120–240 mL of water to minimize gastrointestinal irritation and protect dental enamel.

Consuming undiluted ACV is strongly discouraged due to risks of esophageal injury, tooth enamel erosion, and gastric discomfort. Long-term, high-dose intake may also interfere with potassium levels or interact with medications such as insulin, diuretics, or digoxin. Individuals with gastroparesis, peptic ulcer disease, or chronic kidney disease should avoid ACV unless explicitly advised by a healthcare provider.

There is no established daily “recommended” dose for apple cider vinegar, as it is not an essential nutrient nor an FDA-approved therapeutic agent. Its use should be viewed as a complementary practice—not a substitute for evidence-based medical treatment. Patients considering regular ACV consumption should consult their physician, particularly if managing diabetes, hypertension, or taking prescription medications.
