Apple Cider Vinegar: Miracle Remedy or Scam?

Vinegar, used for its medicinal properties for thousands of years, has undergone a revival. Is apple cider vinegar's "miracle remedy" reputation justified?

Some in the media have touted apple cider vinegar as a miracle cure-all. Wishful thinking, sadly. Miracle cure-alls are few and far between. Having said that, there is some research that supports apple cider vinegar’s use in certain conditions. So let’s delve into the science—limited though it may be—of this aromatic fluid.

What Is Apple Cider Vinegar (ACV)?

Vinegar can be made from a variety of fermentable carbohydrates including grapes, berries, rice, and, you guessed it, apple. During the fermentation process, yeast turns food sugars into alcohol. If acetic acid bacteria (acetobacter) are present, the alcohol is then converted to acetic acid.

Many commercial vinegars are made by a rapid fermentation method. Slower, more natural methods result in the formation of a slime, composed of yeast and bacteria, that you see in the bottom of raw, unfiltered apple cider vinegar. Yes, it sounds gross, but it may actually be good for you. (See also “Top 5 Healthy Beverages.“)

Along with acetic acid, vinegar also contains vitamins, mineral salts, amino acids, polyphenolic compounds (which have antioxidant properties), and nonvolatile organic acids. In the United States, vinegar products must contain a minimum of 4 percent acetic acid per 100 ml, as specified by the Food & Drug Administration.

Potential Benefits of Apple Cider Vinegar

Apple cider vinegar (ACV) has been touted to help with a wide range of conditions, including cardiovascular disease, cancer, and diabetes. It also is thought to reduce or treat infection. As with many alternative therapies, however, research on its effectiveness is scanty.

The reasons for scant research? For one thing, there has been little money available to researchers; for another, the studies that have been done are small and lack statistical power.

Yet there are some results worth considering.

Apple Cider Vinegar and Blood Sugar

Dietitian Carol Johnston of Arizona State University’s Department of Nutrition has been studying the effects of vinegar on blood glucose for years. Johnston’s research indicates that vinegar can help reduce blood sugar in healthy people and those with prediabetes and type 2 diabetes (late-onset). “What acetic acid is doing,” she theorizes, “is blocking the absorption of starch.”

If you have diabetes, it’s important to tell your doctor, as apple cider vinegar may interfere with medication.

Data collected by another research team suggests that vinegar ingestion at bedtime may have a favorable impact on “waking glucose concentrations in type 2 diabetes… but much more work is required to determine whether vinegar is a useful adjunct therapy for individuals with diabetes.”

Apple Cider Vinegar as Bacteria-Fighter

A 2017 study aimed to investigate the effect of apple cider vinegar against two common harmful bacteria, E. coli and S. aureus, and the fungal infection C. albicans. They concluded “ACV has multiple antimicrobial potential with clinical therapeutic implications.”

Again, however, more research is needed.

Apple Cider Vinegar as Weight Loss “Supplement”?

A popular use of apple cider vinegar is in weight loss. Some find that ACV reduces their appetite and makes them feel full sooner, perhaps because it delays gastric emptying.

One study looked at 175 obese Japanese adults. Researchers found that “body weight, BMI, visceral fat area (belly fat), waist circumference, and serum triglyceride levels were significantly lower in both vinegar intake groups than in the placebo group.” However, the weight loss was minimal—two to four pounds over 12 weeks.

The study suggests that apple cider vinegar may prove to be a useful adjunct to portion control, a healthy diet, and regular exercise in the weight loss battle.

Apple Cider Vinegar: Impact on Skin and Hair?

Austin dermatologists Adam Mamelak, MD, and Miriam Hanson, MD, support the use of apple cider vinegar as part of your skin and hair care routine.

Dr. Mamelak explains ACV can help “remove bacteria and excess oil from the skin that can contribute to acne formation.” He explains it is also useful for treating toning skin and for dandruff, yeast infections, insect bites, scrapes, abrasions, and warts.

Dr. Mamelak and Dr. Hanson warn a careful approach; ACV is acidic and can irritate some people’s skin and scalp. They also advise that you test your reaction to ACV with a “patch test” on the skin of the inside of your arm. Never use ACV on the delicate skin of your genital area or leave on any skin for a prolonged time, as it can cause chemical burns.

Other Potential Uses of ACV

There’s also evidence—albeit lower-quality evidence—of the benefits of apple cider vinegar with a number of other health conditions:

  • Heart disease. Studies in rats show that ACV can reduce blood pressure, triglycerides, total cholesterol, and oxidative stress.
  • Cancer. Another study showed that the growth of human cancer cells in the laboratory could be inhibited by vinegar, but there is a lack of evidence in humans bodies.
  • Cough and sore throat. See sidebar below.

Safety of Apple Cider Vinegar

ACV is pretty safe, if taken in small doses and diluted. According to one report, there are rare reports of adverse reactions. ACV is acidic by nature and so can cause acidic injuries and inflammation of the back of the throat, esophagus, stomach, and skin. It also can erode the enamel of the teeth, so if you drink it, rinse your mouth thoroughly with water and wait 10 minutes before brushing teeth. ACV should not be used for teeth whitening as it may cause serious damage to the teeth.

Final Verdict on Apple Cider Vinegar

Most of the claims about apple cider vinegar’s health benefits are not supported by compelling research. Even so, ACV may be considered as a complementary therapy to traditional medicine in weight loss, minor sore throats, and coughs, and in pre-diabetes and type 2 diabetes (only with your doctor’s consent).

If taken in small amounts, in a diluted form, as a drink or in salad dressing, ACV is pretty safe. Just remember to rinse your mouth to prevent damage to tooth enamel.


Does apple cider vinegar help ease a sore throat and cough? In my experience, yes. And I’m in good company when I offer anecdotal evidence for the use of ACV for symptoms that accompany a sore throat and cough. Nearly 2,500 years ago, Hippocrates, the father of modern medicine, used apple cider vinegar with honey to treat coughs, sore throats, and wound infections.

I first tried apple cider vinegar around a week into a bout of sinusitis, when I was struggling to make time to visit a doctor. As I drank the weird-tasting concoction, I was skeptical. But 10 minutes later, the pain under my eyes was gone, as was with the irritating cough of postnasal drip.

While I was unable to find any research studies on apple cider vinegar treatment for coughs and colds (after all, who on earth would fund that kind of research?), I have countless reports from friends and family that it works. Its effectiveness probably comes from the natural anti-inflammatory/anti-infection properties of apple cider vinegar.

    • Thanks for your comment. I have done a little reading on the ACV pills. There are problems when a natural product is turned into a pill. First as the supplement industry is unregulated you can’t be sure what is in these pills. Next because natural remedies contain thousands of ingredients which all work together it is hard to replicate this synergy in the lab, so the act of turning it into a powder may reduce some of the power. On the plus side taking it as a pill will eliminate the problem with acid on the teeth and esophagus. What I would say is try both and see what works for you. We all have bodies that work in different ways. If the pills work just as well as the liquid then go for it! – Leonaura

  • Interesting information. Good to read an overview based on researh, even though the research is meager. I am always skeptical of remedies that claim to cure a number of conditions. This article offers a balanced overview, acknowledging possible benefits despite few scientific studies.

    • Thank you for reading the article and taking the time to comment. I too am a skeptic about remedies with amazing claims. At University Health News we always look for quality research. One problem with “alternative remedies” is the lack of research studies, due largely to lack of funding. Nature has been healing us with food long before modern medicine evolved. I believe in personalized medicine: If a remedy has few side effects and works for you, then go for it.

    • There is a lot of anecdotal evidence that ACV can help with reflux, especially if you have low levels of stomach acid. I was unable to find research to back this up however. If you have significant reflux discuss the use of ACV with your doctor. Remember everyone is different. If you try ACV for your reflux and it really helps you, then it really helps you! Always drink diluted however.

  • What do you know about ACV and honey helping with arthritis? Have been tempted to try it, but would like a little more info before I do.

  • Hi. I was surprised at the remedy for coughs and sore throats. As a beekeeper mixing honey with boiling water destroys all the beneficial properties of honey. Always use water that is warm not boiling or you are wasting your money and destroying a precious gift from nature.

    • Eileen, thanks for your comment. That’s a very good point! In this recipe it’s mainly used to make the ACV palatable. Personally I take raw manuka honey when I have a sore throat, local honey is excellent too. Honey is a powerful remedy indeed, which may prove a valuable weapon in the fight against antibiotic resistant bacteria. Keep up the good work helping nature’s miracle workers.

  • I use ACV for acid reflux. I only use it every other day. One tablespoon in 1/2 cup warm water. It works so well for me that it has replaced the daily prescription Nexium I had been taking for over 6 years. Love this stuff!

    • Carrie, thanks for your comment. That’s great! I take it for this too, I found the medication made me worse but ACV and a tea called Stomach Ease do the trick.

  • Great article-I started to have about 2 table spoons per day about 60 days ago and have felt good benefits with my arthritis pain and lost some belly fat

  • In response to Judy’s question, raw ACV (unpasteurized) contains the “mother” (the slimey thing at the bottom”, which is a colony of bacteria that turns the cider into alcohol and then into vinegar. You don’t need to actually drink the mother to get the beneficial bacteria. Just shake the vinegar gently, let it settle a bit, then use what you need. You can use the mother to make your own vinegar too. : )

  • Forget about anyone spending large sums of money doing research on ACV. No money to be made here. Just losing money for big Pharma from the greatly diminished sales of all those dangerous proton pump inhibitors. I have used ACV every day for 30 years, two generous tablespoonfuls in 6 ounces of water first thing in the AM. Previously, I had a lot of stomach and GERD issues. Since using ACV daily, I have hardly had a burp for 40 years. SO FORGET THE RESEARCH!! “The proof is in the puffing”! I am age 77, and healthy as a horse. Also, I am a retired Registered Pharmacist with over 50 years of experience. Great article, but do remember one important thing……IT MAY TAKE A MONTH OR TWO OF USING ACV AS I OUTLINED BECAUSE YOU MUST FIRST DESTROY ALL THE BAD BUGS AND REPLACE WITH THE GOOD ONE. Probiotics help to speed up the healing process, like ALIGN OR KYODOPHILOUS. BE PATIENT WHEN YOU TRY THIS!! This works for most folks…..period. And many other health benefits of ACV as outlined in the article. ACV, while an “acid”, creates an ALKALINE BODY…..this is what we want for real health. Look this up on the internet. HATS OFF TO ACV!!!

  • using apple cider vinegar in everything for over 35 years and believe it has helped me and all the people we introduced it to!

  • I always find it interesting that articles that mention anything “alternative” always suggest “talking to your doctor” before making any changes. At the same time they admit that there is not sufficient research and most physicians are not trained in nutrition, so THEY KNOW NOTHING about nutritional therapies! There are better ways to get advice on nutritional therapies–do your research. Just because there’s no research on ACV does not mean it doesn’t work!

  • I use ACV in pill form, I no longer have abdominal cramps, IBS, nausea. I also have more energy. So I think there is something to be said for the use of ACV !

  • Carolyn C, thanks for your comments. At UHN we aim to provide research based advice from medical authorities – that’s our remit. Many sites offer anecdotal evidence on natural remedies, but some of this is misleading, contradictory and even harmful. It is a great shame that more money is not spent on researching natural remedies, but that’s just the reality of the world we live in. We also have to offer warnings to the public, to see their doctor as we aim to cause no harm, I believe that people should see their doctor if they have a medical problem, so as to get an accurate diagnosis before taking any treatment, conventional or alternative. I also agree that many doctors are not trained in nutrition, but we are fortunate in the USA to have access to nutritionists and many other practitioners, whose work complements that of the mainstream medical profession.

  • I found that ACV did suppress my appetite. But i had to stop for a while because i was experiencing two symptoms…..constipation on some days, and diarrhea on other days (sorry for the graphic desciption). I’m really torn because I love what ACV does as an appetite suppressant.

  • Bragg’s is very good… does contain the mother liquor. I tried it, but it seemed to not agree with me. So I stick with just plain old Heinz Apple Cider Vinegar. It has worked like a charm for me for 40 years, as outlined in my comments above of 8-20-18. Not so much as a BURP. I am sure other reputable brands will do the same. The chemical components are the same as far as I can discern.

  • One of my daughters introduced me to a fresh use of apple cider vinegar last Summer, when my kitchen was seeming overwhelmed by fruit flies attacking the apples, peaches etc. that were on the counter as well as any fruits served on a plate or in a bowl. We left a few small glasses or dishes of apple cider vinegar around the kitchen and dining room and discovered the fruit flies were going there first, diving in and, effectively, committing suicide.

  • I use a combo of one tablespoon of Braggs apple cider vinegar, one half a small fresh squeezed lemon, one scant tablespoon organic honey and one-eighth tsp turmeric in a mug of warm water each morning. No side effects negative or positive but it makes me feel healthy. Plus, it tastes good! Thanks for your articles. Joyce Becker

  • Lou S. That’s a great tip! I’ve never heard of using ACV to kill fruit flies. I will definitely try it next time we have a problem with them.

  • I can’t stand the taste, I love my water, so I have just drank 2 teaspoons when I get up, I know you can use honey or mapple syrup ,don’t like those either, any suggestions

  • Some people suggest that ACV may help remove certain calcium deposits which can cause joint pain etc. For sure, ACV will react with (dissolve away) calcium carbonate, so taken over the long term, who knows?

  • I’m 72 years old female. I recently began having itching and inflammation on my skin around my genital area. It may be due to vaginitis because I know it’s not a yeast infection. I just used a little Bragg’s ACV on a cotton ball and dabbed it around the area, and I gradually felt the skin inflammation calming. Has any of you females tried this for a similar issue?
