Can apple cider vinegar benefit your stomach?

But, whilst the popularity of apple cider vinegar has grown in recent years, apple cider vinegar has been used for thousands of years as a natural remedy. And just one of those uses has been to use apple cider vinegar for a range of stomach concerns, like bloating and even supporting weight loss.

If you're interested in learning more about how apple cider vinegar (ACV) can help your stomach and gut, keep reading as we'll give you the low-down on everything you need to know.

Apple cider vinegar, distinct from the vinegar used in fish and chips, is a product of apple cider fermentation. Bacteria, known as ‘the mother’, along with yeast, ferments the natural sugars in apples. After a while, the cider will turn into alcohol and, after further processing, into the apple cider vinegar we know and love.

There are two types of ACV: with 'mother' and without. ACV with 'mother' retains good bacteria from fermentation, whereas ACV without has been filtered to remove the ‘mother’.

All this means is that apple cider vinegar with 'mother' is full of good bacteria used in the fermentation process as it is not filtered out after production. The 'mother' contains friendly bacteria that may play a key role in supporting digestive health.

Even though apple cider vinegar without the mother has been filtered, it doesn't mean it loses all its properties. But choosing ACV with the mother means you get even more of the good stuff.

Bloating is a normal stomach process, often caused by gas buildup. You'll likely notice when you're bloated as you may feel a fullness or tightness in your stomach or lower abdomen.²  Bloating is typically caused by one of three things: food intolerances and/or eating habits, hormone fluctuations, or underlying medical conditions.²

The bacterial content of apple cider vinegar is thought to help support the gut microbiome. In 2021, a case study reported that apple cider vinegar was used as part of a combined treatment that included the consumption of 1-2 teaspoons of ACV before meals for gastrointestinal problems. However, because of the combined nature of the treatments given, the researchers could not say for sure, which element of the treatment worked.³

It is really important to understand that there are many causes of bloating. You should always check with a medical professional if you have any concerns, as they can help you figure out the cause.

Many people who take apple cider vinegar believe its acetic acid content may help the body digest food, particularly foods rich in protein.⁴

Several scientific mechanisms have been suggested for how and why apple cider vinegar might affect digestion, but the research is still very limited.⁵

A pilot study in 2007 found that apple cider vinegar was effective at increasing gastric emptying, but the trial participants all had type 1 diabetes, so it is not clear if the effects will be the same in people without diabetes.⁶  Unfortunately, there have not been any further studies on this.

The use of ACV for weight loss has long been a talked-about topic, with celebrities and wellness influencers worldwide claiming apple cider vinegar is the new weight loss ‘saviour’.

Some research has indeed found that apple cider vinegar was an effective strategy for helping modify diets - alongside other factors such as a healthy balanced diet and moderate exercise - in people who were overweight.⁷

It is important to note that in these trials, it is not the apple cider vinegar per se that causes the weight loss. Instead, apple cider vinegar contributed to changes within the body, including a decreased appetite, which may lead to weight loss. These research studies also paired apple cider vinegar treatments with reduced calorie diets to study the effects, which may have influenced the findings.

Apple cider vinegar is not a silver bullet, and taking it will not cause dramatic or sudden weight loss by itself. If your aim is to lose weight, you should always look at holistic ways to do so, such as exercising regularly and eating a healthy, balanced diet.

Large ACV amounts may lead to side effects, including tooth enamel erosion, medication interference, decreased potassium, allergic reactions, and throat damage

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.

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.

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.

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.

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.

Apple cider vinegar has the potential to be a great inclusion in many people's diets and routines, as there are emerging signs that it could be a versatile and beneficial product.

Unfortunately, there is no miracle cure for any health concern, and no supplement should be viewed as one. Whilst apple cider vinegar has the potential to help with some concerns, some people may notice no changes, or might even experience some side effects.

If you find yourself experiencing discomfort or experiencing any symptoms that you are unsure about, you should always check with a medical professional.
