This article will give you a clear idea about the side affects you can expect while having apple cider vinegar and a few tips on how you can avoid having those side effects.

Here is an outline of how we are going to proceed with the article:



Today the use of apple cider vinegar is limitless; they are being used in almost all domains starting from using it as an ingredient in food dressing to skincare to use it as a health drink. Apple cider vinegar is an alcoholic product with about 1.2-8% of alcohol.

It is a fermented product made from apples during alcoholic fermentation, which further leads to another fermentation where the actual produce “vinegar” is formed, which is later named apple cider vinegar[1].

The critical element of apple cider vinegar is the presence of acetic acid that mainly gives the taste and smell to the product. This crucial element is a by-product formed called the “mother of vinegar,” which contains the probiotic microbes and enzymes [2].


As discussed due to the acidic contents of the apple cider vinegar, it obviously becomes imperative to maintain precautions while consuming or using it. This acidic content may cause a few side effects that may cause some discomfort for you.

Here are lists of few health concerns that you might look into before planning to start using apple cider vinegar. There are two main categories that the side effects of apple cider vinegar can be categorized into Medicinal concerns, Personal concerns, so let’s dive into it.



In general acidic compounds or vinegar are said to have an adverse effect on our tooth; acid basically weakens our tooth enamel on exposing it too long with acidic food beverages.

In fact, consuming too much acidic food is also suggested to be avoided cause it potential to lead to tooth decay. Studies have shown how beverages and drink affect our tooth health and gum, as well [3].

Undiluted form of apple cider vinegar is the most dangerous way to consume it, and that can cause tooth damage. The decay in tooth might not be visible to our naked eyes, but on the consumption of apple cider every day or on a regular basis, one may notice a weakening of tooth, pain in gum, and increase in sensitivity towards hot and cold food.

Studies have also researched on the side effects of apple cider vinegar on a tooth such as:

  • One study in 2014 investigated the erosive potential of vinegar on our tooth enamel sample; it was an in-vitro study not performed directly on humans. The results showed that vinegar has tremendous erosive potential and may lead to tooth problems, in-fact the vinegar was able to cause 1-20% mineral loss from the teeth after only 4 hours[4].
  • Another study was conducted by a researcher on a 15-yr old girl, where the girl was diagnosed for erosive tooth wear due to daily consumption of apple cider vinegar to reduce weight[5].
  • A study in 2014 also tried to examine the effects of vinegar on tooth bleaching and found that vinegar, like white vinegar, apple cider, and hydrogen peroxide have, acts as a bleaching agent and causes color change but also slowly erode the outer layer and damages the hardness of our teeth.[6]

The science behind it:

Tooth, as we all know, is the hardest substance in our entire body and the enamel of the teeth that is the outermost layer of the teeth is a non-living thing that is they lack any living cells in it; thus our body cannot replace the eroded parts of our teeth once it’s gone[7].

  •  Apple cider vinegar has about 1.2-8% acid content in it, with a ph. of about 2.5-3, this being the concentrated form of the ACV we get in the market.
  • Use of this concentrated acid directly causes the action of the acids on our tooth, thus leading to sensitivity, erosion, and decay.
  • APPLE CIDER MAY CAUSE THROAT BURN Irritation in the throat due to the drinking of apple cider vinegar can be a common side effect; the acidic content in the apple cider may cause burn in the esophageal.

Consuming concentrated form of apple cider can cause the throat burning sensation. The primary reason is said to be due to the acetic acid. Any kind of oral overuse of the apple cider vinegar eventually leads to this side effect.

Scientific studies on it:

  • A study by Laura L Hill and coworkers tried to evaluate various apple cider vinegar pills and its effect on throat; they found that the pills’ misuse due to poor instructions led by the company of the pills can cause esophageal injury[8].
  • Another study in 1994 stated that vinegar could cause some serious esophageal lesions on children[9]

The effect of apple cider may vary from person to person; not everyone can digest and tolerate it well.

Vinegar, in general, is good too as a source of vitamin and minerals and can be useful to use as a salad dressing, but consuming it, especially if one has some history of stomach ache or problem, may not be an excellent idea for them.

Although it is true that apple cider vinegar gives the feeling of fullness and slows down the digestion process and the vinegar and the pungent nature of it can cause the feeling of nausea and unpleasantness among many people.[10]

Scientific studies:

  • In conditions where people suffer from gastroparesis, which essentially occurs when our stomach does not clear the food, thus keeping the food in the stomach for a long time is also not beneficial.[11]

Thus it is always suggested to keep a track of one’s blood sugar level for people suffering from diabetics and gastroparesis.

  • APPLE CIDER MAY CAUSE SKIN BURN When applied directly onto the skin in concentrated form, the high acidity of apple cider vinegar may cause skin burn.

Since our skin can be quite sensitive to any chemical-based products, acidic content in certain products and vegetables like lemons are to be avoided by many dermatologists to be applied directly on the skin.

The undiluted form of apple cider vinegar can cause skin rashes, irritation, and burn, which may require proper medical treatment further.

Scientific studies:

  • Clinical reports given by The Journal of Clinical and Aesthetic Dermatology in 2015 say that a teenager cider of 14 years old ended up with chemical burns on her skin when she tried to use apple vinegar to remove her moles on her nose.
  • There are other reports on skin problems and burns caused due to applying apple cider vinegar listed by National Capital Poison Center[12]

Thus the topical application of apple cider vinegar either as a toner of face washes is not suggested, especially if it is in the concentrated form. People tend to use it as home remedies looking at various influencers and maybe on the internet itself, but it’s essential to get a clear idea of what you are getting into.

In fact, according to U.S. Food & Drug Administration and MedlinePlus, the use of other chemical exfoliates and toners such as glycolic acid and salicylic acids are much more efficient and effective unclaimed apple cider vinegar when compared[13] [14].


Bloating is a feeling of discomfort when your belly feels all swollen after eating or in the morning, most of the time, it’s caused due to excess of gas production

Apple cider vinegar can give you a bloated feeling, as we are known by now that ACV mainly reduces the rate at which our food gets processed and digested in our body; thus, the food remains in our body for longer than usual.

This overstay of food in our body may cause gas production and cause some serious bloating problems.

  • Insulin- ACV can have a direct effect on people who take insulin as a diabetic patient.
  • Drugs that are meant for lowering our potassium level or excrete potassium from our body may get affected because apple cider has an adverse effect on potassium in our body.


Hypokalemia is a condition that is caused due to low potassium levels in our bodies.

Lowering of potassium in our body can cause other effects, such as wreaking of bone and brittleness in our bone; the mineral density of our bones reduces.
