The potential side effects of apple cider vinegar
Large ACV amounts may lead to side effects, including tooth enamel erosion, medication interference, decreased potassium, allergic reactions, and throat damage
Erosion of tooth enamel:
The high acid content in apple cider vinegar could erode the enamel on your teeth over time.9
Try drinking apple cider vinegar through a straw to avoid contact with your teeth, and always make sure it is diluted.
Decreased potassium levels:
Those who saw a decrease in their potassium were found also to be taking certain medications for their heart and sometimes taking common diuretics.10 If you’re taking any form of medication, it's best to speak to your doctor before trying ACV - they will be able to confirm if it is safe for you to take.
Allergic reaction:
Allergies are common, and you might not be aware that you have an allergy to ACV if it is not already part of your diet.
If you experience any signs of an allergic reaction after taking apple cider vinegar in any form, such as a rash, trouble breathing or swollen eyes and throat, contact your doctor immediately.
Damage to your throat:
Similarly to the potential to erode your tooth enamel, the high acid content of ACV can cause damage to the soft tissue of the mouth, throat and stomach.11
Always dilute your apple cider vinegar before drinking.
Interfering with medication:
Like any supplement, it is always best to check with a doctor before taking it to ensure you are safe and not taking something that may affect any medication.
