Apple cider vinegar (ACV) can interfere with medications for diabetes, certain blood pressure drugs (like diuretics and some ACE inhibitors/ARBs), digoxin, and certain laxatives. These interactions can lead to dangerously low blood sugar or potassium levels.
Who Should Avoid Apple Cider Vinegar?
Kalakota notes, apple cider vinegar contains acetic acid. "Consuming it just contributes to the acid in your stomach that's already causing issues," says Dr. Kalakota. "It can actually just worsen acid reflux."
Combining certain drugs with apple cider vinegar can have unintended effects, such as low potassium levels or low blood sugar. Examples of drugs that may interact with apple cider vinegar include insulin and other diabetes drugs, diuretics (water pills), ACE inhibitors, ARBs, digoxin, and certain weight loss drugs.
Apple cider vinegar is effective in preventing oxidative stress of the kidneys. It increases the levels of antioxidants in the body, balances blood sugar levels and reduces blood pressure, creating optimum conditions for kidney health. Apple cider vinegar contains citric acid which dissolves kidney stones.
1. Don't take it straight. If you're thinking about downing some apple cider vinegar and then quickly eating or drinking something else to mask the bitter taste, you may want to think twice. While there are many ACV health benefits, drinking it this way may be more harmful than helpful.
But if you are still looking to add apple cider vinegar to your diet, try it in moderation. There's no official guidance for how much apple cider vinegar to drink daily. It's generally believed that mixing 1 tbsp to 2 tbsp of apple cider vinegar into your water or tea is safe.
Apple cider vinegar offers numerous health benefits, including improved digestion, weight management, and blood sugar regulation. However, it also comes with potential risks such as tooth enamel erosion, digestive discomfort, and interactions with medications.
The vinegar can also interact with some drugs, such as diuretics, laxatives, and insulin. Always ask your doctor if it's safe to use ACV with your current medications. If you have low potassium levels (hypokalemia), too much ACV could make the condition worse. That's because large amounts can reduce potassium levels.
“It contains the antioxidant chlorogenic acid, which has been shown to protect LDL cholesterol particles from becoming oxidised, a crucial step in the prevention of heart disease process. Additionally, there are also some studies showing that the vinegar can help reduce blood pressure.
Coffee and tea – Caffeinated beverages aggravate acid reflux. Opt for teas without caffeine. Carbonated beverages – The bubbles expand in your stomach, creating more pressure and pain. Choose plain water or decaf iced tea.
Because of the acidity of apple cider vinegar, drinking undiluted apple cider vinegar can trigger or worsen symptoms in people with digestive problems such as acid reflux. Apple cider vinegar can also cause damage to the esophagus. Some people may also experience an upset stomach after consuming apple cider vinegar.
Increased irritation: ACV's high acidity can aggravate the esophagus, particularly when it's not adequately diluted. Tooth enamel damage: Regular consumption can erode enamel if taken undiluted. Worsening symptoms: For many GERD patients, acidic foods and drinks—including vinegar—can trigger flare-ups.
However, regularly drinking apple cider vinegar can also degrade the tooth enamel — leading to pain and an increased risk of tooth decay and costly dental procedures. Additionally, apple cider vinegar is known to cause esophageal ulceration and burning, gastroparesis and low potassium levels in some instances.
Combining a vitamin D-3 supplement and a tablespoon of ACV per day (about 1,000 mg) in a glass of water, food, or in supplement/gummy form, up to two times per day may support your metabolism, helping it burn fat a little faster.
Taking apple cider vinegar (ACV) daily in moderation (1-2 tablespoons diluted) might offer benefits like slight blood sugar reduction and modest weight loss support, but long-term, high doses can erode tooth enamel, irritate the throat/stomach, cause digestive issues, and lower potassium levels, potentially interacting with medicines like diuretics and insulin. It's crucial to dilute it in water, avoid large amounts, and consult a doctor, especially if on medication, as it's not a miracle cure and excessive intake carries risks.
Apple cider vinegar may affect potassium levels. Czerwony says you shouldn't use it if you already have low potassium levels (hypokalemia), as it could make the condition worse. Drug interactions. If you take any medications, ask your doctor whether you can safely take apple cider vinegar.
Furthermore, prescription medications like ACE inhibitors, used for managing hypertension, can interact poorly with apple cider vinegar. The combination can heighten the likelihood of low blood pressure, leading to dizziness or faintness.
Claim: It promotes gut health
Apple cider vinegar contains natural probiotics because it is a fermented product, Wohlford said. Probiotic-rich foods boost the amount of healthy bacteria found in our gastrointestinal tract and have been linked to immunity, brain health and more.
Experts haven't found meaningful weight loss or long-term hunger control with use of apple cider vinegar. And many of the studies of apple cider vinegar and weight loss have been small or lacking in other ways. Some small studies suggest that apple cider vinegar may have promise as a weight-loss aid.
Excessive Alcohol Consumption
When alcohol is consumed, the liver works overtime to metabolize it. Over time, excessive alcohol consumption can lead to inflammation, scarring, and even cirrhosis of the liver. This chronic damage significantly increases the risk of liver cancer.
In the first 1–2 weeks, you may notice subtle improvements such as reduced bloating, better digestion, and stabilized energy levels. Visible weight loss, however, typically occurs after consistent use for 1–3 months, especially when paired with a healthy diet and exercise routine.
Liver detox symptoms often include fatigue, headaches, digestive issues (bloating, nausea, constipation), skin problems (rashes, itchiness), and mood changes, as the body processes and releases toxins, but these can overlap with liver dysfunction; signs of serious issues include jaundice (yellow skin/eyes) and dark urine, warranting medical attention.
Negative Side Effects:
Consuming large amounts of undiluted ACV can cause digestive issues such as nausea, diarrhea or heartburn. Interference with medications: People taking certain medications like diuretics or insulin should avoid consuming large amounts of ACV due to potential drug interactions.
