Who Should Avoid Apple cider vinegar?

Apple cider vinegar (ACV) has earned a loyal following for its supposed health perks — from aiding digestion to supporting weight loss. But despite its popularity, it’s not a one-size-fits-all remedy. In fact, for some people, it can do more harm than good.

“If your stomach burns or your teeth hurt, apple cider vinegar is not for you,” says dietitian and nutrition expert Jennifer Azzaro. That burning sensation? It’s a red flag. The high acidity of ACV can irritate the stomach lining, especially in people with acid reflux, gastritis, or ulcers. Even when diluted, regular consumption may worsen symptoms and lead to discomfort or damage over time.

And it’s not just the digestive system that’s at risk. The acidity can also erode tooth enamel, increasing sensitivity and raising the risk of cavities — especially if you’re sipping it straight or not rinsing your mouth afterward.

Those with sensitive skin should also be cautious. While some swear by topical ACV for acne or skin toning, applying it directly can lead to irritation, dryness, or even chemical burns in extreme cases. Skin reactions vary widely, so patch testing is essential — but avoiding it altogether may be wiser for those with conditions like eczema or rosacea.

Ultimately, natural doesn’t always mean safe for everyone. While apple cider vinegar may offer benefits for some, listening to your body is key. If you experience pain, burning, or discomfort — whether in your gut, mouth, or on your skin — it’s best to skip it. As with any remedy, what works wonders for one person might simply not suit another.
