6 side effects of excess apple cider vinegar

Discover the 6 side effects of excess apple cider vinegar.

The excessive use of apple cider vinegar has certain negative effects. Therefore, although it is a product with benefits, it should be used in moderation. We tell you more about it.

Some people are completely unaware of the possible side effects of excess apple cider vinegar. Although this product is attributed to health properties, its use in abundant quantities leads to unwanted reactions that even pose a danger.

So far, there is not enough evidence on the safety and efficacy of this natural ingredient. Therefore, although it can be included in the regular diet, moderate and punctual consumption is recommended. Are you interested in knowing more about it?

What is apple cider vinegar?

Apple cider vinegar is an organic product that is obtained through the combination of apples with yeast.


During its process, the yeast transforms the sugars in the apples into alcohol. Then, by adding bacteria to it, the alcohol is fermented in acetic acid to a concentration of 5 to 6%.

This acid is classified as a ” weak acid ” and this is responsible for many of its beneficial effects. However, the product also contains water and other micronutrients.

According to research published in Critical Reviews in Food Science and Nutrition, the acetic acid contained in apple cider vinegar contributes to lipid metabolism and lowers the risk of obesity and type 2 diabetes. So why should it not be consumed in excess?

A digestive upset could be due to the acid in apple cider vinegar.

Side effects of excess apple cider vinegar

Although it is known as a healthy product, too much apple cider vinegar triggers serious side effects.


Because of this, it should always be taken with caution, avoiding too high doses. Also, as far as possible, it is better to dilute it in water. What can cause?

1. Delays the emptying of the stomach

Large consumption of apple cider vinegar can worsen the symptoms of gastroparesis. The latter is a common condition in people with type 1 diabetes. It consists of a malfunction of the nerves of the stomach, which makes it difficult to empty it.

What happens is that this ingredient slows the rate at which food leaves the stomach and enters the lower digestive tract. Consequently, it reduces high blood sugar spikes but also slows the absorption of nutrients into the bloodstream.

Symptoms include the following:




•Abdominal distension.

2. Causes digestive discomfort

In some people, apple cider vinegar is irritating and causes stomach upset. Although there are studies that associate acetic acid with a greater feeling of satiety, several hypotheses suggest that this effect is the result of the indigestion that it causes.

In a controlled study that was published in the International Journal of Obesity, a group of people consumed a drink with 25 grams of apple cider vinegar. In the end, they reported that they had a decreased appetite, but also an unpleasant feeling of nausea. 

3. It is associated with low potassium levels and bone loss

To date, there are not enough controlled studies on the relationship between apple cider vinegar and blood potassium levels.


Nor are there any about its link to further loss of bone mass. However, there is a publication on a case report of these effects.

Specifically, through Nephron, it was reported that a woman who consumed large amounts of apple cider vinegar, for a long time, had to be admitted to the hospital with low potassium levels and alterations in blood chemistry.

The woman consumed about 250 milliliters of apple cider vinegar diluted in water for 6 years. The diagnosis showed osteoporosis and mineral leaching from the bones. In addition, the doctors determined that the excess acid could also reduce the formation of new bone.

4. May cause tooth enamel erosion

Consuming excessively acidic foods and beverages causes deterioration of tooth enamel.

While there are more studies on the effects of soft drinks and fruit juices, there is also evidence of the damage that acetic acid causes in this layer that covers the teeth.


A publication in the medical journal Clinical Laboratory states that vinegar can cause a loss of between 1% and 20% of dental minerals after four hours.

However, the study was done in a laboratory and not in the mouth, where saliva appears to help mitigate heartburn.

In any case, the general recommendation is to avoid direct exposure of the teeth to pure undiluted apple cider vinegar.

5. Produces throat burns

Watch out! Consuming too much pure apple cider vinegar can cause esophagus burns.

This is stated in a review published in Acta Paediatrica, in which the effects of the consumption of harmful liquids accidentally ingested by children were observed.


The researchers determined that the acetic acid in vinegar was the acid that caused the most burns in the throat. For this reason, they classified it as a “powerful caustic substance” that should be out of the reach of children.

Acetic acid can damage tooth enamel when consumed in excess.

6. It can cause skin burns

Some state that the application of apple cider vinegar on the skin has certain benefits; however, its application in excess and without dilution seems to cause the opposite effect.

In a case report published in The Journal of Clinical and Aesthetic Dermatology, a 14-year-old girl suffered nose erosions after following a protocol seen on the Internet with this product.

In another case, a 6-year-old boy suffered burns on his legs after his mother applied apple cider vinegar to him to fight infection.


It seems that these risks decrease after diluting the vinegar in water. However, it is recommended to do a little test of the product before using it on large areas of the skin.

Apple cider vinegar should not be used in excess

The key to avoiding these unwanted effects of apple cider vinegar is to avoid overusing it. So far, in moderate amounts, it is considered safe and beneficial for most people. 

In any case, the idea is to consult your doctor before consuming it regularly. Remember that you can sometimes have drug interactions. Therefore, it is better to avoid it in case of being under some treatment
