Apple cider vinegar, often shortened to ACV, has long been used in cooking and more recently in natural health routines. Many people take it to support digestion, balance energy, or as part of a wellness plan. But while some find it helpful, others have reported side effects such as stomach upset or diarrhoea. Understanding why this happens and how to manage it is important for anyone thinking of adding ACV to their daily routine.

Why Apple Cider Vinegar May Affect Digestion

Apple cider vinegar is acidic and contains acetic acid, which can stimulate the stomach and digestive system. For some people this can be beneficial, as it may help with food breakdown and nutrient absorption. However, the same acidity can also irritate the stomach lining if taken in large amounts or without dilution. This irritation may lead to loose stools or diarrhoea, especially if the body is not used to it.

The Role of Dosage and Dilution

One of the most common reasons for digestive discomfort with apple cider vinegar is taking it in its concentrated form. Drinking ACV neat can be harsh on both the mouth and stomach, and it increases the risk of side effects. UK nutrition guidance typically suggests that if vinegar is being taken as a drink, it should always be diluted with water. A high intake can overwhelm the digestive system, and the body may respond by moving food through too quickly, resulting in diarrhoea.

Individual Sensitivity and Health Conditions

Not everyone reacts to apple cider vinegar in the same way. Some people can take it regularly with no issues, while others may experience discomfort even in small amounts. Those with irritable bowel syndrome, reflux, or sensitive stomachs may be more prone to diarrhoea after using ACV. The acidity can also interact with certain medicines, particularly those affecting blood sugar or diuretics, which makes it even more important to be cautious.

Other Possible Digestive Effects

Diarrhoea is not the only digestive response linked to apple cider vinegar. Some people notice bloating, cramping, or a feeling of nausea if they take it on an empty stomach. This is often the body reacting to the acidity. While these effects are usually temporary, they can be uncomfortable and may discourage continued use. For those who experience repeated side effects, it may be a sign that ACV is not suitable in its liquid form.

Safer Ways to Use Apple Cider Vinegar

For those who wish to use ACV without the risk of digestive upset, there are a few approaches. Diluting it in a large glass of water and drinking it with food may make it gentler. Using it in salad dressings or cooking rather than as a drink is another way to benefit from its flavour without overwhelming the stomach. For people who find even small amounts too harsh, supplements such as apple cider vinegar gummies can provide an alternative. These are designed to deliver the potential benefits of ACV in a more controlled way, reducing the likelihood of diarrhoea or stomach irritation.

Balancing Expectations

It is important to remember that apple cider vinegar is not a cure-all. While it may support digestion for some, it can also be irritating for others. Experiencing diarrhoea from ACV does not necessarily mean it is dangerous, but it may be a sign that the amount being taken is too high or that the body is not tolerating it well. A cautious approach, starting small and monitoring how you feel, is always best.

When to Seek Advice

If diarrhoea persists after taking ACV, or if it is accompanied by pain, dehydration, or other concerning symptoms, it is sensible to stop using it and seek medical advice. People with existing digestive conditions, or those on medication, should check with a healthcare professional before adding ACV to their diet. This ensures it fits safely into their overall health plan.

Conclusion

Apple cider vinegar can cause diarrhoea in some people, mainly due to its acidity and how it affects the digestive system. While this side effect is not uncommon, it often depends on how much is taken and whether it is diluted. For those who still want to explore its benefits without the discomfort, apple cider vinegar supplements may be a gentler choice.

If you are looking for a more convenient way to enjoy the benefits of ACV without the sharp taste, our apple cider vinegar gummies are a great alternative. They are easy to take, taste great, and fit effortlessly into your daily routine.
