Learn important information about Apple Cider Vinegar in Earth Clinic's new video.

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!

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.

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?

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.

Apple Cider Vinegar

I have been taking about 1 tablespoonful with lemon and (occasionally honey), warm water and a little grape juice in the morning. Always feel well with it. However recently I got overly keen and applied it straight to my hair/scalp, no water, and left on for hours. Not a good idea I think.

I have begun losing hair each time I brush/comb and never used to do so. After 6 weeks hair feels quite thin and very itchy on the scalp at the back. This might be a detox reaction so not too worried about that.

I am going to stop for a month to gauge reactions and if I continue to consume I shall take much smaller amounts. Otherwise generally healthy for my age. Did anybody else notice any hair loss directly attributable to ACV?

I love Apple Cider Vinegar but it doesn't love me. Every time I try it, I get a yeast infection. I read in one of my health books that some people with Candida can NEVER use ACV. Is there any way to overcome this?? I feel better when I drink it and need it for digestion.

Thank you!! Love earth clinic!!!!

Gypsylady, might lemon juice do?

When you use it it starts to fight the yeast in your body, so it causes outbreaks. I get yeast infections when I detox or eat too much kefir or any other good thing. Yeast is a large battle to fight. I am not fighting mine anymore. I am just slowly bringing my health back and good microbes and Ph balance. Keep on the healthy track but go slow and low dose.

It's possible that ACV is only bringing out the yeast that is already in your system---healing crisis---that manifests itself as an infection.

WE need hydrochloric acid in the stomach for optimum digestion. .As we age, the acid diminishes and digestion is impaired, which gives rise to a host of illnesses. Apple cider vinegar helps to increase the acid and this enables proper digestion. Vitamins like the b-complex, specially the b8 and the b12 can only be absorbed if the proper amounts of HCL are present. Some of us might experience sensitive teeth or burning throat from drinking the vinegar. Dilute it or use the pills.

and b12

Karne, start low and slow! 1 teaspoon daily is enough of a start.

I have found ACV to be useful in helping with blood pressure and overall health, particuarly during winter months. Two tablespoons in glass of water.

Hi Earth clinic,

I wanted to check with you about my intake of ACV which has been going for last 6 months, but I have lately got the pityriasis rosea rashes on my torso/stomach/ribs/back area.

Are they both interlinked i.e., can taking ACV cause these rashes with PR, should I be worried off? also can I still continue taking the ACV and would this worsen the rashes count .

Thank you,

I tried Apple Cider Vinegar for the fungus in under my thumb nail and I started having cramps, stinky gas, and intolerance to ice cream and chocolate. Never had these problems before. Stopped drinking it and I'm back to my self again.

It sounds your body was going through a detox period. It gets bad before the healing comes. You should start it again and push through it.

I would love to know, when taking Apple Cider Vinegar shots straight, could it cause a rash, of the toxins coming out of my body?

Has anyone experienced prickling? For 6 weeks I took 1 tbs Apple Cider Vinegar in a glass of water in the morning to cure my acid reflux...which it did 100% and no reactions. Then suddenly after the 6 weeks I started getting itchy on my chest and a rash up my neck (like I do sometimes with certain wines) and now have pricking all over. I was feeling fabulous taking the ACV and so I tried only taking it every second day but with the same symptoms to then just a tsp in a glass of water but still no difference. I have stopped taking the ACV for the past 3 days and the prickling is almost gone....I really want to continue taking it but not sure if it's a good idea if it turns out I'm allergic to it?

I love how taking ACV makes me feel but ACV really makes my teeth sensitive. I tried 1 tsp a day through a straw and couldn't bare the sensitivity. How can I get it down without touching teeth?

Replied by May

Do you dilute the vinegar before drinking it through a straw? You could try apple cider vinegar capsules available online or in the healthfood store.

Replied by Timh

Take the "tablet" form of ACV; is my preferred method.

To Dear E.C.

I am feeling a little nauseous after upping my dosages of BSM, ACC, Bicarbonate of Soda and Coconut Oil (separately) for arthritis. I feel as if my kidneys are under pressure, though I have no history of kidney problems and my recent blood tests were fine. It could be an arthritis flare up or a "Healing Crisis" (I forget the term R_____(?)) I suppose but how would I tell the difference?

Not sure whether to back track or persevere! Thanks.

EC: We think you mean Herxheimer Die-Off Reaction

Replied by Michael, New Zealand

Yes, that's it-Herxheimer Die-Off Reaction. or possibly "Healing Crisis".

Does that fit my situation and could you describe it for me please. Is there anything on your site that describes it?

I meant ACVinegar (not ACC) sorry about that typing slippage. Thanks

I read some information about ACV and it's positive effect on candida growth so I thought I would give it a try. After trying it twice a day (one tablespoon to 8 oz of water) for four days, I gave up. It was making me sick. I was having heartburn and feeling generally unwell and tired. I usually wake up in the morning with energy but instead I am dragging myself out of bed and struggling through the day. I just don't understand why it affects me this way but I am done!
