Apple cider vinegar, often shortened to ACV, has gained popularity in the UK as a natural health supplement. Many people take it for digestion, energy, or weight management, whether diluted in water or as a convenient gummy. However, alongside the interest comes an important question. Can drinking apple cider vinegar cause diarrhoea? Understanding both the benefits and potential side effects of ACV is key to using it safely and sensibly.

How Apple Cider Vinegar Affects Digestion

Apple cider vinegar is made through fermentation, which produces acetic acid. This acid is what gives ACV its strong flavour and is often linked to its possible digestive benefits. Some people find that small amounts of diluted ACV before meals help stimulate stomach acid, which can in turn aid digestion. However, because it is naturally acidic, too much ACV can have the opposite effect and irritate the digestive system. This irritation may lead to diarrhoea, cramping, or stomach upset if the body struggles to tolerate the acidity.

Why ACV May Cause Diarrhoea in Some People

Diarrhoea can occur if apple cider vinegar is taken in excess or not properly diluted. The acidity may speed up the movement of food through the digestive tract, which reduces the time the body has to absorb water and nutrients. As a result, stools can become loose. ACV may also affect gut bacteria, as acetic acid has antibacterial properties. While this may be helpful in some cases, it can upset the natural balance of the gut if consumed in large amounts. For some people with sensitive stomachs, even small amounts of undiluted ACV can be enough to trigger discomfort.

Underlying Health Conditions and Sensitivity

Not everyone reacts to apple cider vinegar in the same way. People with existing digestive issues, such as irritable bowel syndrome, acid reflux, or inflammatory bowel conditions, may find that ACV worsens their symptoms. In these cases, diarrhoea or increased stomach irritation is more likely. Similarly, those with weaker enamel or throat sensitivity may struggle with the acidic nature of vinegar when it is taken as a liquid. Supplements such as gummies or capsules can help avoid some of this irritation, although they should still be taken in moderation.

Safe Ways to Take Apple Cider Vinegar

If you are considering adding apple cider vinegar to your routine, it is important to do so gradually. Diluting one to two teaspoons in a large glass of water is generally safer than drinking it neat. Taking it alongside meals can also reduce irritation, as the food helps buffer the acidity. Listening to your body is essential. If you experience diarrhoea, discomfort, or nausea, it may be best to reduce the amount or switch to a supplement form. Consistency is more important than taking large amounts at once, so starting small and monitoring how your body reacts is a sensible approach.

When to Seek Advice

Occasional mild digestive changes may not be cause for concern, but persistent diarrhoea, pain, or discomfort should not be ignored. In these cases, it is always best to speak with a GP or healthcare professional. They can help determine whether apple cider vinegar is the cause, or if another underlying issue may be contributing. It is also worth remembering that ACV is not a replacement for medical treatment. While it may support general wellness when used sensibly, it should not be relied upon as a cure or solution for digestive problems.

Balancing Benefits with Side Effects

Apple cider vinegar can be a useful addition to some people’s diets, particularly when taken in moderation. However, the risk of diarrhoea is real if it is overused or not diluted properly. For many people, switching from liquid vinegar to a supplement such as gummies makes it easier to manage the acidity while still gaining the potential benefits. This way, the risk of irritation is reduced and it becomes a more enjoyable part of daily wellness.

Conclusion

Drinking apple cider vinegar can cause diarrhoea in some people, especially when consumed in large amounts or without dilution. While it may support digestion for some, it can irritate the stomach for others. The key is moderation, careful preparation, and awareness of how your body responds.
