Why Does Apple Cider Vinegar Cause Side Effects In Some People and Not In Others?

Because apple cider vinegar is a powerful detoxifying remedy, side effects from ACV can occur if the body goes into a weakened state when it is leached of important minerals like magnesium and potassium during the detoxification period. Loss of vital magnesium can lead to ailments such as heart palpitations, arrhythmia and atrial fib. Loss of potassium can lead to blood pressure issues.

Could I Be Allergic to Apple Cider Vinegar?

Apple cider vinegar is high in histamines, a chemical that is released by cells in response to injury and in allergic and inflammatory reactions. For histamine-sensitive people, this can be very problematic. Research suggests that high levels histamines are associated with anxiety or panic attacks.

High histamine symptoms include:

  • Anxiety
  • Dizziness
  • Nausea
  • Vomiting
  • Headaches
  • Hypertension
  • Arrhythmia

How Can I Cure Side Effects From Apple Cider Vinegar?

If you are experiencing side effects from drinking apple cider vinegar, stop drinking any and all vinegar immediately. Symptoms should begin to abate in 24 hours. Drink plenty of water during this time. Make sure you do not accidentally consume any additional vinegar in your diet, like salad dressing, for example. Also, soy sauce should be avoided as it can also cause a high histamine response and trigger additional heart rhythm issues.

One of the best supplements you can take to cure side effects from ACV is Magnesium.  Magnesium L-Threonate is an excellent form of magnesium and easy on the stomach. Powdered magnesium like Calm is also helpful, just don't take too much at one time or you will get diarrhea!

My husband has been taking _____s apple cider vinegar for about 6 months, and olive leaf extract for two months. Suddenly his body is like a sebaceous cyst factory. They are popping up everywhere. He has had 3 removed, we got rid of the infected one with castor oil and manuka honey, and just today he showed me a new cyst on the back of his neck. These cysts have just kind of appeared on stage and I'm wondering if the vinegar and OLE have created a detox or cleansing thing in his body and the toxins are coming out as cysts. What do you think?

Apple cider vinegar is extremely acidic and it pickles the liver. The liver cells struggle to stay balanced and perform as they fight for oxygen, because vinegar steals oxygen from the bloodstream and the liver. ACV (like any vinegar) comes into the stomach extremely acidic. The liver must put a halt to it immediately and use its every reserve to try to alkalize or at least neutralize it. The ACV fights back, and its acidic nature is so strong that the stomach loses the battle many times over. Instead of alkalizing your gut, it does the opposite. It weakens hydrochloric acid and breaks down gastric juices and heads down the pike still acidic. It's basically an assault on the stomach and intestinal tract. For more information on the effects of apple cider vinegar on the liver, see book "Liver rescue" from Medical Medium Anthony William.

I used apple cider vinegar for years and then I noticed my legs and ankles hurting, I thought it was me just getting old. I stopped taking the acv and the pain went away. When I tried it again the pain came back, so I know it was the acv.

For 2 mos. I was drinking 1 tlbs. of ACV and 1 tlbs. of Maple Syrup in a glass of water, daily. I loved the way it made me feel but then I started noticing my hair was falling out. Has anyone had any issues with this happening?

Replied by Mimi

Hi, Zanybees. I can relate, however not personally. I recommended apple cider vinegar (without the maple syrup) to a family member and felt horrible when she told me she experienced hair loss! She did achieve health benefits also; losing a few stubborn pounds and gained more energy, but I am still curious as to why this happened. I don't think it should be used on a daily basis by everyone.

I was taking ACV for a number of health conditions. I was taking it at 1/2 to 1 tsp in 8 oz water and 1/4 tsp baking soda and a little honey. I started having uncontrollable and very painful exploding diarrhea. It was like the drink was going straight through me so I switched to the capsules of AVC thinking it may have been hard on my stomach but the same thing happened. I love the way ACV helps my depression and blood pressure and pains but I can't handle the diarrhea. What other forms are out there and what else can I use or do?

Marilyn, a couple of things for you to try to continue taking the Apple Cider Vinegar and bs, you can either attempt for a one week period taking only the baking soda, then slowly reintroduce the acv, at a smaller dose, or simply cut your dosage in half until you find what works for you. Eg. If you now do one half teaspoon of bs twice a day cut down to 1/4, then 1/8,1/16 etc, if you get down to a pinch then so be it, you have to find what works for you. You can always increase later. You can also alternate lemon/ lime with the bs. I believe you have toxins which explains the diaorrhea. Best to you

Hi Marilyn,

Maybe not adding the BS to the ACV would help. I would try taking the BS separately, thirty minutes or so after you have a meal.

Hi. Kelly

Stop consuming ACV for a week - start with 1-2 drops of ACV in 1oz of water after meal - increase the dose by 1 drop so as water by 1 oz each week - find your dose - start to use before meal when you have a succesfull try - otherwise reduce the dose and return to recent use - needs no additives as it is self-sufficient to treat and is suitable for long term use unlike soda(good for 1 month use) - wash your whole oral with water diluted peroxide/or water (1:1) each time.

Good luck.

My experience is that I get nausea whenever I add baking soda, otherwise, it is just fine with 1 tbsp of ACV and equal amount of lemon juice in 8 once's warm water.

You can drink celery juice instead!

For some people: Be careful of celery juice. I was drinking it daily for a week and noticed my tongue was getting numb. During the 2nd week, my mouth was numb inside too. The only thing I changed was adding the celery juice (4 stalks with some water) daily. I did some research and found out that celery naturally contains eugenol which is an an anesthetic. This does affect a lot of people but not all. So if you notice any numbing inside your mouth after drinking celery juice, it's not in your head. I had to quit drinking it.


please elaborate.

I've just started the AVC again - having gallbladder attacks on and off. I have exploding diarrhea. I will stop it now.

I also drink celery juice and just had this morning. So will celery juice stop the gallbladder pain? Has not for me today.


Dear Eleana,

When my go-to remedies for a gallbladder attack do not work, usually a castor oil poultice with a heating pad will calm things down. See this page for more info:

But if I am having frequent attacks, it means I am due for a gallbadder flush/cleanse.

I hope you feel better soon. I know it is miserable.

I have started taking ACV 2 tsp in warm water on an empty stomach and have noticed my urine staring to smell bad. Is this a normal side effect?

For some reason, ACV aggravated my constipation and made it worse.

I would just like to quick add that yes Apple Cider Vinegar does really seem to help some people, it is soooo the opposite for me. *It is not one size fits all! * In my home 2 of us do NOT handle Apple Cider Vinegar well & the other 2 of us are fine & helped. Just because you, your relative, or your neighbor has success with Apple Cider Vinegar does not mean that all others will. FYI ours is the organic kind, in a glass bottle, & of course with the "mother". Also worth noting, Apple Cider Vinegar was bad for the health of one our black labs, but our other lab is perfectly fine with it. ---My negative reactions (that I am aware of) are as follows: my mineral count gets all messed up, my PH actually drops pretty badly, my body temp drops significantly, joints get very painful, general unwell feeling, can be constipating, & some serious tummy/gut pain. It is a shame, because I want it to help with x/y/z, but I wind up worse.

So..someone suggested me to take apple cider vinegar in the morning (empty stomach) for reducing belly fat and I started doing that since last couple of weeks. Today I missed to take it and what I realized is that my ankle pain is very mild today than what it was yesterday and day before. (I have mild ankle pain from a year or so.) Yesterday, the pain was more and I was able to notice it when I started driving. That's why I started searching on google to see if Apple Cider Vinegar is responsible for my increasing my ankle pain. But everywhere on internet I see it reduces such pain.

Confused.. I will try to monitor for next few days and I guess that is the only way I will get the right answer..

Two weeks ago I was diagnosed with calcium deposits in my shoulders. I began using apple cider vinegar to resolve the crystals. Yesterday I suddenly became extremely dizzy and went to the hospital. I was told I had benign positional vertigo. Could the apple cider vinegar have released crystals in my ear?

Replied by Rskorj

I doubt that BPV is brought on by Taking apple cider vinegar. If you were diagnised correctly - You may have bumped your head somehow to cause the crystals to move out of their correct place. My husband got BPV from trying to get the water out of his ear after showering by hitting the side of his head repeatedly. BPV can be fixed by special manouvers that get the crystals back into place. There are videos on you tube that show you how to do it.

I have been upping my probiotics. I use about one bottle of kombucha (which I adore) ever other day and varying amounts of raw ACV (which I also like). I have been getting hives whenever I use them now. Hives doesn't seem like a common detox reaction. My scalp is especially affected, my waist, and then just spots here and there. I have had dandruff and itchy oily scalp for years. Recently I tried a different shampoo which appears to have eliminated the dandruff and oil. It isn't even a dandruff shampoo. I like using ACV in place of soap in the shower and to condition my hair.

After using ACV for six weeks, twice a day I mixed a teaspoon with soda water and really enjoyed it. I lost weight as I was not as hungry but I did develop itchy rash on my torso and worse, bleeding from the bowel and increased vaginal bleeds. I'm hoping now I've stopped the ACV, the bleeding will also stop as my HB levels are now quite low and doctors are concerned. Scopes to follow.
