Apple Cider Vinegar Water Side Effects: 5 Risks

Apple cider vinegar water can erode tooth enamel, upset the stomach and irritate the throat. Other, less certain concerns involve potassium levels and interactions with diabetes medication.

Dilution makes apple cider vinegar water less acidic than undiluted vinegar, but it does not eliminate every risk. You do not need to drink it for health or detoxification.

Is apple cider vinegar water safe? 5 possible side effects

Food-grade apple cider vinegar diluted in water may be tolerated by some adults, but there is no established risk-free amount or dilution. Effects can depend on how acidic the drink is, how often you consume it and whether you have a condition that makes acidic drinks harder to tolerate.

A 2020 systematic review of 13 human studies examined apple vinegar’s safety and metabolic effects. Human evidence remains limited, so it cannot reliably establish how often each side effect occurs or the long-term safety of apple cider vinegar water. The order below is practical rather than a proven ranking of frequency.

Apple cider vinegar water is not necessary for detoxification. The liver and kidneys do most of that work, while the lungs and gut help eliminate waste.

What can apple cider vinegar water do to your teeth?

Tooth enamel erosion

Apple cider vinegar contains acetic acid, which can soften and gradually wear away tooth enamel. Enamel does not grow back, and erosion can contribute to sensitivity and a greater risk of dental problems.

If you choose to drink apple cider vinegar water, dilute it rather than drinking the vinegar straight, and avoid sipping it throughout the day. Rinse your mouth with plain water afterward and wait before brushing; brushing immediately can further wear acid-softened enamel.

Evidence strength: The ability of acidic drinks to erode enamel is well established. The amount of enamel damage specifically attributable to diluted apple cider vinegar water, and the frequency of that damage, are less certain.

Can apple cider vinegar water upset your stomach?

Nausea and stomach discomfort

The acidity of apple cider vinegar water can be unpleasant or irritating for some people, particularly when the drink is strong. Nausea, a burning sensation or abdominal discomfort may make it difficult to tolerate.

Do not drink undiluted apple cider vinegar, and avoid it if it repeatedly causes symptoms. If you decide to try a diluted drink, having it with food rather than on an empty stomach may be more comfortable, although that is not a guarantee against irritation.

Evidence strength: Stomach complaints are plausible, but studies do not establish a reliable rate for nausea or discomfort from apple cider vinegar water. Persistent symptoms deserve medical assessment rather than repeated attempts to adjust the drink.

Can apple cider vinegar water irritate your throat?

Throat irritation and reflux symptoms

An acidic drink can irritate the mouth, throat or esophagus, especially if the apple cider vinegar is undiluted or the mixture is strong. It may also aggravate symptoms in someone who already experiences reflux or heartburn; that does not mean it causes reflux disease in everyone.

Stop drinking it if you notice burning, pain or worsening heartburn. Diluting apple cider vinegar does not make it a treatment for reflux, and continuing to drink it despite discomfort may prolong irritation.

Evidence strength: Acid irritation is biologically plausible, but good evidence is lacking on how often diluted apple cider vinegar water causes throat symptoms. Severe pain or trouble swallowing needs prompt medical attention, not further experimentation with the mixture.

Can apple cider vinegar water lower potassium?

Possible low potassium with excessive use

Low potassium has been reported in connection with prolonged, heavy vinegar consumption, but such reports do not prove that ordinary amounts of diluted apple cider vinegar water cause it. The mechanism and the amount that might pose a risk are uncertain.

Avoid treating apple cider vinegar water as a daily supplement, especially in large or concentrated amounts. If you have low potassium or take a medication that can affect potassium, ask your clinician whether to avoid it and whether you need monitoring.

Evidence strength: This is a rare, uncertain concern based on limited reports, not a demonstrated common effect of apple cider vinegar water. Muscle weakness, cramps or an irregular heartbeat can have several causes and should not be used to diagnose low potassium at home.

Can apple cider vinegar water cause low blood sugar?

Possible interaction with diabetes medication

Apple cider vinegar has been studied for possible effects on blood glucose, but the evidence is not strong enough to predict what a particular drink will do. If it does lower glucose, an additional effect alongside insulin or other glucose-lowering medication could potentially increase the risk of low blood sugar.

If you have diabetes and take medication, check with your clinician or pharmacist before using apple cider vinegar water regularly. Follow your existing blood-glucose monitoring and low-blood-sugar plan; do not change or stop medication because of the drink.

Evidence strength: The interaction is a precaution, not a proven or predictable effect for every person. Studies of apple vinegar do not establish a safe dose of apple cider vinegar water for people taking diabetes medication.

Who should avoid apple cider vinegar water or ask a clinician first?

Avoid apple cider vinegar water if it causes pain, nausea or worsening reflux. People with enamel erosion, sensitive teeth or other dental problems should ask a dentist whether acidic drinks are appropriate for them.

Check with a clinician before using apple cider vinegar water regularly if you have diabetes, low potassium, kidney disease, reflux or a condition affecting swallowing. This is especially important if you take insulin, other glucose-lowering medication or a diuretic, because your condition or treatment may make the potential effects more consequential.

During pregnancy or breastfeeding, ordinary food use is different from taking concentrated vinegar or drinking it routinely for a supposed health benefit. Ask a clinician before using it as a supplement. Do not give it to children as a routine health drink without advice from their pediatrician; a safe supplemental amount has not been established.

Is there a safe daily amount of apple cider vinegar water?

There is no established safe daily amount of apple cider vinegar water, and there is no need to drink it every day. Research has not identified a dilution that guarantees protection for teeth, the throat or the stomach.

If you choose to drink it, use food-grade apple cider vinegar diluted in a full glass of water, rather than taking it straight. Have it with food if that is more comfortable, avoid prolonged sipping and stop if it causes symptoms.

When should you see a doctor?

Contact a clinician if nausea, abdominal pain, heartburn or throat discomfort persists, recurs or worsens after drinking apple cider vinegar water. A dentist can assess new tooth sensitivity or suspected enamel damage. Tell the clinician or dentist what you drank and how often, along with any medicines you take.

Seek emergency help for trouble breathing or swallowing, severe chest or abdominal pain, vomiting blood, black tarry stools, severe confusion or fainting. If someone has swallowed a concentrated vinegar product and has symptoms, contact a local poison control center or emergency service promptly; do not make them vomit.
