acvTwo years ago, while looking online for a natural remedy for a nasty sore throat, I stumbled upon a fantastic website called It is a repository of anecdotal information regarding folk remedies and holistic cures. I was amazed to find Apple Cider Vinegar (ACV) combined with a spoonful of honey, a squeeze of lemon, and a dash of cayenne pepper, would ease my sore throat and sinuses (it worked!). But, I was more intrigued by the number of postings from people who use ACV to control their blood sugar. Like many of you with Polycystic Ovarian Syndrome (PCOS), I am insulin resistant. I can’t tolerate Metformin, so I’m always looking for ways to control my blood sugar through diet, exercise and supplements like the Insulite PCOS System.

Before I embarked on a new regimen, I wanted to see if there was any scientific data to support all of the positive ACV testimonials. I did discover that in ancient Greece, around 400 BC, Hippocrates, the father of modern medicine, prescribed apple cider vinegar mixed with honey for a variety of ills, including coughs and colds. (1) With further investigation, I found that Professor Carol Johnston Ph.D. has been working on the subject of vinegar and diabetes with her research team from the Department of Nutrition at Arizona State University. Her studies have recently shown that drinking apple cider vinegar slows the rise of blood sugar after the consumption of a high-carbohydrate meal. (2)

In Dr Johnston’s initial study, 29 people had orange juice and a bagel for breakfast, which contained a total of 87 grams of carbohydrates. Two minutes before the meal, half of the subjects were given 20 grams (about 4 teaspoons) of apple cider vinegar mixed with 40 grams water and 1 teaspoon saccharine. The other half were given a placebo drink. A cross over trial was conducted a week later, at which time the placebo group received the vinegar. The participants’ blood sugar levels were measured before and after the breakfast. They were classified into 3 separate groups:

  • 10 people with type 2 diabetes
  • 11 people with insulin resistance
  • 8 healthy control people

Although all three groups in the study had better blood readings after meals begun with vinegar cocktails, the people with insulin resistance experienced a 34% reduction in their blood sugar levels after the meal. Those with type 2 diabetes, experienced blood sugar levels reduced by 19%. The researchers reported in the January 2004 issue of Diabetes Care that the vinegar had an effect on the volunteers’ blood sugar comparable to what might be expected from diabetic drugs, such as Metformin.

Based on these results and two other recent studies, (see references 3 & 4), Dr. Johnston thinks that the vinegar tonic interferes with the absorption of high-carbohydrate foods which reduces the blood sugar rise that normally occurs after a meal. She states in her findings that, “The acetic acid in vinegar may inhibit enzymes that digest starch so that carbohydrate molecules aren’t available for absorption and are eliminated as fecal matter.” She suspects that the acetic acid is the anti-diabetic ingredient in the vinegar.

Everyday I splash 2tsp of raw, unfiltered organic ACV such as Braggs in 16oz of water and drink this 2xday. In the summer it is actually refreshing iced (it really just takes the place of a squeeze of lemon in your water). In the winter I often drink it warm like a tea. In addition to lowering blood sugar, ACV also detoxifies and balances PH levels. Give ACV a try for a few weeks and let me know what you think. I can almost guarantee that it will not only keep sugar cravings at bay but you may also lose a few pounds.

  1. […] know that I am a big fan of organic apple cider vinegar (ACV). You can read my previous post here.   I use ACV to help control my blood sugar, but it also has many other great […]

  2. You said you drink it twice a day. Could you elaborate? Do you take it before any meals or before bed?
    I just recently started drinking a similar mixture and am interested in your “schedule”

    • Thanks for your question Mela. I am actually enjoying the Body Ami product. You can read my review about it on my blog. What I currently do is put a “splash” of Body Ami probably about 2-3tsp in a liter bottle of water and sip it throughout the morning. Then I do the same thing around 4PM and sip it throughout the evening.

      When I am not using Body Ami I put the same amount of Bragg Organic Apple Cider Vinegar and a splash of Pomegrante juice in the liter bottle of water.

  3. I was recently diagnosed with PCOS and want to go the natural route. Please email me updates!!! Thanks:)

    • Lena-
      The natural route has really worked for me. You can sign up for updates via feedburner by clicking on the RSS button on the top of the home page. I hope to keep my blog more up-to-date. Life has been busy juggling three kids these days. I have been more apt to post interesting tidbits of info on Twitter and Facebook lately. Thanks for your comment!

  4. Thank you so much Amy for providing so much helpful information, I am so happy to have come across your site! I was diagnosed 11 years ago with pcos, and unfortunately the doctor did not mention that meant insulin resistance as well. I have been eating clean and working out 5-6 days a week since May 1 2010, lost 36lbs, however this seems pretty slow being that I have been working so hard, and still suffering from low blood sugars. I will be getting my thyroid and sugar levels checked this week. So now I have just been searching for natural tips on how to manage pcos.
    Thanks again!

    • Thanks so much for your comments. Are you eating enough protein? Make sure to have protein at each of your 3 meals and 2-3 snacks a day. YOu may actually need to eat more to lose more. You may need to fire up your metabolism. Also try to eliminate gluten for a few weeks and see how you feel. Keep up the good work!

  5. I am so grateful for the work you put into your site because it has changed my life. I went a year and 6 months without having a naturally induced period, after years of being regular. I refused BCP and decided to try ACV before going on Met. After reading your blog. Three weeks of having my morning ACV cocktail, I got my period. I hadn’t changed my diet..weight remained the same…I told my hub-o it was just a fluke. Well, I kept up with the ACV and 29 days later, I started my period again. It feels like Christmas In my home.
    Again, thank you for the time you take to share your knowledge and experiences.

    • Jamie-
      I am so glad that I was able to help. Kudos to you for making this consistent change!
