I have been using Heinz brand ACV for about 3-4 weeks now. I have kept it in my office and drink it there. Couple days ago when a colleague saw me drinking it, she said it thins the blood, so be careful. Is that true? If it does thin the blood, what then are its effects (good or bad) on our bodies? Thanks.

does acv darken skin colour?

Don't use Heinz brand!!! The only brands you should ingest are the natural brands with the MOTHER in it. That is the stuff in the bottom of the jar. This is the stuff that helps the most. Make sure it is shaken well.

I was on Klonopin for 14 years and am off for 4 years now. Having anxiety attacks, panic attacks, balance problems are horrible. I took ACV and it made me feel good for a couple of days but now I have a possible UTI, shakes, dizziness, I am wondering could this be the detoxing of my body? please email any responses.

Six months ago, I started to drink ACV twice a day for weight loss but stopped in about two weeks cos' the ACV has made me hyper and couldn't sleep through the night. I retried drinking it again a week ago to cure my hair loss and the same happen to me. Now I'm drinking one cup per day (2 tbs of ACV) in the morning to keep my energy high during the day and skip the evening cup. Does anyone has the same experience?

I have been taking _____s ACV off and on for 3 years and discovered not to take it too late in the day. I was having night sweats and insomnia. ACV acts as a cleanser/detoxifier. I find it best to take 1 tbsp. per 16oz. water water with a meal.

I ws using Heinz brand ACV for 5 days before I realised I have to use the organic one as remedy for my food allergies. I was totally fine with using 2 tbsp Heinz brand (diluted in 16 z water with a dash of lemon juice, salt and pepper, so I bought 2 big bottle of Eden brand organic ACV when I found it. I mixed it the same way as Heinz (the ACV might have been just a tsp or so more than 2 tbsp as I accidently dropped more in the glass)and drank some of it before lunch and continued drinking after lunch. To my surprise, shortly after lunch my head started to hurt. I never get headaches, so I was surprised. I hoped it would get better shortly, but instead it went on increasing and the whole left side of my head was so terribly paining I had to take a pain killer. I was feeling so weak with the pain I actually didn't even have the energy to go and get the pill...I really had to force myself to do it as I couldn't bear the headache. To add to this, I had been feeling nauseatic sometime around when the headache started and then I vommitted a whole lunch was thrown out. I suffered from headache, nausea (followed by vommitting)and weakness and my body felt cold for nearly 5 hours and even then it was the painkiller that helped get rid of the these problems.

I do not like and can't eat apples but because I was perfectly fine with Heinz brand I didn't suspect anything will go wrong with the organic brand. I don't think I am ever going to take it again.

But I would like to know why all this happened to me. What is it in the organic ACV that caused me to have a severe headache? Why did I throw up all my lunch (which is again a very rare thing for me to do). I have read some other readers also complaining of such side effects - why does this happen to some of us? What is wrong with us?

Will the commercial brand give the same results as opposed to the organic one, as I seemed fine with the Heinz brand?

EC: Quite a few readers over the years have reported great results using a brand like Heinz. Ted thinks it works just fine too!

Hi Sangeetha. You are describing a migraine headache -- ouch! Poor thing. The only time I get migraine headaches is sometimes after flying (sinus pressure) or if I get too much sun, so I can't say much about that. But I think you might try another brand of apple cider vinegar cautiously once you have fully recovered.I bought a brand of organic acv (gold cover on it, can't remember the name) and got really sick from it. It was too acidic, caused terrible heartburn that lasted for hours. So a different brand might make a difference.

Hi Tess, Thanks for your response. I never get migraine headaches and hardly any headaches. I do get a slight headache if I am out in the sun for too long, but that is totally bearable and I don't need to take any pain killer. As for the brand, I doubt if I can find any other brand of organic ACV in Cayman Islands.

Has anyone had problems with Eden brand organic ACV? Which is the brand most acceptable by others?

EC: Bragg is the most popular by far.

Replied by Sangeetha

Thanks for confirming commercial brand ACV also gives results. What I would like to know is what is the main difference between the oganic and the non organic brands? Does it take longer time to get the results with the non organic brand? Thanks.

EC: A couple posts on the Q&A page of ACV that may be helpful:

I also have had severe headaches after taking ACV. I took 1 tablespoon in 8oz of water, and ive had a killer headache for the past 12 hours. I wish someone here would explain why it gives headaches as a side effect. I cannot find information for this anywhere.

I experienced ACV migraine side effects also. I used 2 tbsp in water with a dash of honey for two days. Migraines both days, with nausea and light-headedness. Is this detox, or something else? If it's detox, I really can't start the ACV until I'm on vacation from work, because I felt so horrible today that I called out sick.

Replied by Kaffee

In reply to Trevor and Jan: it does sound like your headaches are due to detoxing though it is difficult to be sure. Are you drinking enough water each day to flush this out? Coffee enemas work wonders for relief of this, causing the gall bladder to empty out accumulated toxins into the gut for discharge, which in turn allows the liver to further process the toxic build-up in the blood which causes the headaches. Effective in minutes but you must be well hydrated every day to use them. Google 'coffee enema detox' for more info.

Msg for Trevor Jan and Sangeetha. I agree with Kaffee. The headaches might be due to the body detoxifying itself. It also sounds like you are taking too much ACV. It should be 2 teaspoons instead of tablespoons. Also organic ACV might have something to do with it and how your body reacts. I have not gone the organic route yet. So far the the regular store brand is doing wonders for me. I figured I would use up what I had on hand first. If both work the same, I will continue to use the store brand for economic reasons. Suggestion would be to reduce the dose per day or try an every other day regimine with 2teaspoons every other day. The 3x per day is generally recommended for when your body is fighting off a cold. For routine maintenance daily your body should not need so much. Just increase if you get sick then decrease dose when you are healthy again.

I have heard bad things about taking the ACV in pill form. There have been reports where it has caused burns to the esophogus <--(spelling?) and that's not something that i would play with... scarred throat tissue is no fun.

I too had ulcers for years and yes the ACV bothered my stomach for awhile but it eventually healed my ulcers. i was taking daily stool samples to the doctor because of bleeding ulcers and after a few weeks on _____s ACV my ulcers were healed. I have numerous tests and I no longer have ulcers. I do believe in _____s ACV because it is smoother and has a lot of valuable nutrients. I drink 3 tsp. in a cup pf water with just a touch of baking soda to cut the tartness at least twice a day.

Replied by Pamela

You might try the acv with 1/4 tsp of baking soda. I tried acv with honey and it caused all kinds of stomach problems. I figured out it was the honey. Now I use 1/4 tsp of baking soda in it (which I learned from this website),and for me it works like a charm. Be sure to use raw organic acv as grocery store avc I've read has toxins and other issues that can cause problems.

Hey I took ACV pills for 4 weeks and today I switched to ACV liquid. I took 1 tbsp in 16OZ water and was sipping it through out the day and I feel a heart burn...should I stop taking it?

Replied by Albert

I've been taking ACV (_____) for almost a year with 1-2 tbsp. and was used for getting rid of seasonal allergies and escezma; now that it's gone I continue to use it generally for detoxing. I find it's best to slow down the intake of ACV by having a meal/snack before a dose or sips. It will give your digestive system time for it to get accustomed to ACV by slowing it with food. From experience and what I've read, some people have a harder time dealing with high acidity of certain brands of ACV. Different brands vary, but it's best to use the organic ones for it being more potent and less diluted or stripped off it's minerals, amino acids, etc. And as for your concerns of heartburn, it usually means that your body is slowly moving the toxins out of your body. It will wear off in a couple of days or 1 or 2 weeks depending on your health condition; just remember to take it slooow. A slight pain, discomfort, unusual boost in energy or better mental focus is the norm.

I have been taking ACV (Heinz) as the organic one is not available for my Hypertension which is 130/90 with medication. I took ACY 2tsf in 200ml of water plus 1tbsf of Honey twicw a day before breakfast and before lunch. I tried once to have before dinner but I could not sleep that night (?excess energy). I have noticed my BP shot up to 180/100 in the mornings.Got worried so I thought I would ask if there are any chances of ACV raising the BP?

I know these posts about side effects have gone on for a while now. I can't even read them all. I would just like to put a theory out there, it's a theory because not everyone will believe this.

Sometimes when there is an infected part/organ/area of the body, things that cleanse and disinfect may cause pain. Like Rubbing Alcohol to a cut, or salt to a burn, or lemon juice etc. Perhaps these pains, being internal or external could be the pain of healing?

I do know that everyone's bodies are different, and require different amounts of ACV, or anything at that.

Allergic reactions to ACV, the best way in my opinion on this is to perhaps, eat an apple, drink a beer, drink some regular apple cider. Anything happen? If you dont have an allergic reaction to these things, then perhaps it could be healing pains. I know, too simple, but a good way to narrow it down.

Try taking very very small amounts of ACV at first, let your body get use to it. I have a crazy approach to allergies, I believe when we're allergic to something, we don't take it in enough. The human body is extremely good at adapting. I know when I first took Niacin, a very good source of detoxifying the body, my ears and skin itched and burned, everything almost itched and burned, but as i kept taking it, that burning went away, i think once it went away, it meant it no longer had something useful to fight off.

I have been taking ACV for just over a week, it has cleared up my uti but I am incredibly tired and have felt depressed since I started taking it, I was hoping this was a sign of detoxing but I don't seem to be getting any better. I also have muscle ache especially in my legs, I usually go the gym 3 times a week but since taking the ACV I have been too tired to do anything.

Does anyone know what has caused this? I would like to keep taking the ACV but not sure if it is right for my body, should I take the symptoms as a good sign that I'm detoxing or that it's not right for my body??

Thanks for your advice, any help is much appreciated!

My grandfather is 93 and has used Apple Cider Vinegar mixed with raw honey and aloe vera everyday for 30 years. He has survived Colon Cancer and Throat cancer. Until the past 2 years he has been healthy as an ox. Warning: A recent side effect has been stomach bleeding which his doctors attribute to ACV.

well i think that would probably be to much acid intake counter-acting the bodys balance of acid already-it may have taken a while for this to happen, but that is usually the case when stomach bleeding occurs. xx

Dear Roz,

Your Grandfather is 93 and still tickin after colon and throat cancer. If he has been taking ACV religiously for 30 years and is just now having problems it could just mean that his body is breaking down as everybody elses does when they are almost a century old. There's no amount of meds, remedies, healthy diet that will keep us alive forever. All we can do is try our best to live as healthy as we can and it looks like your Grandfather did just that. Kudos to your Grandpa for keeping himself healthy, naturally.

I tried one teaspoon of Trader Joes organic apple cider vinegar to two cups of filtered water and sipped it over a three day period to try to lose some weight and to balance my ph. I knew I was sure to have yeast overgrowth so to avoid massive die off I started out conservatively. I also stopped all sugars, yeast and carbs. In spite of such a small ratio of vinegar to water, my face broke out in huge puss filled welts. I've always had an acne problem, even now yet at 59 and post menopausal but this was the worst most painful break out since my teens! I tried putting vinegar and baking soda on the infected areas, just soda, just vinegar but could not get the ichiness to go away nor the swelling. I stopped drinking the vinegar and water but after more than a week I'm only beginning to heal from the acne. It's so severe, undoubtedly it will leave some scars. I fully realize that this reaction indicates my body chemistry must be very imbalanced and needs the vinegar and water. What am I to do? Should I try again with even less vinegar? I also did lose some weight almost immediately and want to go back on the vinegar treatment for this as well

Thanks for any advice.

In response to: 10/12/2008: Sandra ([email protected]) from Los Angeles, regarding your acne break-out.

This is a sure fire way to CURE your acne once and for all! I have shared this remedy with the most severe cases and everyone who tried it could not believe that they cured their life long battle with acne so quickly.

Make sure you buy natural organic yogurt in a glass jar. (Friendly bacteria cannot survive in plastic.)

Buy a loofa thin face pad or facial sponge. DO NOT USE A FACE CLOTH! Why? If you let a face cloth soak in a bowl of distilled water for approx. 10 minutes then swish it around, you will see all the residue detergent and bleach that you used to wash it come out of it. Not good for your skin!

Pour a little of the organic yogurt into a clean little glass jar so as not to contaminate the larger jar. Use the contents of the little jar for several days, then throw out what's left over, wash and dry the little jar and replace with more yogurt from the big jar. Store both jars in the fridge.

Procedure: Rinse your face with as hot water as you can tolerate to open the pores, using the loofa or facial sponge. Quickly, while your face still feels warm, pour some of the yogurt from the little jar onto the loofa or sponge and start scrubbing a section of your face. Rinse the loofa/sponge and re-apply the yogurt to it. Scrub another section of your face. Rinse the loofa/sponge again and repeat until you have scrubbed your entire face.

Now, rinse your entire face with the hottest water you can tolerate and repeat the entire procedure again. Only, this time, when you've finished scrubbing your entire face with the yogurt, RINSE YOUR ENTIRE FACE WITH THE COLDEST WATER YOU CAN TOLERATE, TO CLOSE YOUR PORES.

Pat your face dry.

If you can do this upon awakening in the morning, and before you go to bed, within a few days you will see your acne disappearing. Even the worst cases will clear up entirely within 2 weeks, but do keep up the procedure for 1 mth., and it will never return.

If for some reason, mths go by, and one should appear, just put a dab of organic yogurt from a glass jar on it just before you go to bed and in the morning it should be gone.

The good guys in this type of yogurt are responsible for the cure. Guaranteed!

EC: We've never seen yogurt sold in glass jars!

I tried the 3 T ACV, 3 T Honey, and 8 oz warm water to cure my sore throat. This was a bad idea for me. I am pregnant, so my gag reflux is ultra sensitive. I tried drinking it first, but it really started to nauseate me, so I decided to gargle. As soon as it hit the back of my throat, I threw up.

I am not a doctor or midwife but I have been pregnant before and I have worked in the medical field before also. I have two beautiful, healthy children; I am well read in many different subjects but what I really wanted to say is that I think it was precarious of you to try this remedy while you are pregnant. Did you ask your Dr. or mid-wife first? I personally would not take or drink any concoction during a pregnancy b/c it also affects your baby and if your not used to drinking vinegar or sour things then you will just vomit it up and cause extra unneccessary stress on your body and your baby.

i try ACV when i was pregnant of my first child and nothing when wrong. he weight 9lb and 2onces. i think i can say that ACV added extra nutrition. On my second pregnancy i had so many health problems that i was affraid to try vinegar. i don't know why. maybe what i needed was ACV. but you never know what can happen because you can't see if the baby is ok or not if you eat or drink something. in my case it was ok. if your not using ACV already don't risk it. Don't start right now if your pregnant.

Warnings / Side Effects:

Hi Earth Clinic,

I've visited your site many times and read hundreds of posts, and sent many people here. Thank You for existing!

I have a thought, which I hope will be constructive. In the spirit of making information FINDABLE to those of us who are seeking healing on our own.

After trying ACV to alkalinize myself, I experienced a huge overgrowth of yeast and I was forced to stop taking it after 3 days. This set me back at least a month in my healing. I could not figure out what was happening until I spent an hour or two reading online and finally came across a NAY / Sideeffect post on your site from someone which explained the sense of this to me. I stopped taking the ACV immediately and slowly returned to 'normal'. Now this is a peculiar reaction to ACV, but it was immediate for me, within an hour, and runs counter to most of the information out there, so it is confusing.

It took determination and a lot of time to find this information, and I know you want to make this site easy to navigate, so I am suggesting that you make the various categories (Yea, Nay, Maybe, Warning ) CLICKABLE somehow, so we can read the contents of these categories without digging for them. Most people would not spend the time to search and read every post, as I do. So I am writing in the spirit of helping the general population.

Also, I thought it might be helpful to mention this action of ACV, because it was so devastating to my delicate inner flora. For those of us who are slowly rebuilding a population, the use of ACV might be misleading.

Hi, I had the same thing happen to me. When I first started taking ACV. I don't if you added honey. I figure out it was the honey so I stop adding it and had no more problems. Also use raw organic AVC which is important. I've read that regular store bought vingar can be toxic and will cause problems. Hope this helps.

Hello, I just wanted to make a comment regarding yeast infections as a result of taking AVC. I have had such amazing results in just my first week. I lost 5 pounds right off! I am now regular for the first time in 20 years. My skin looks amazing and the energy is insane. In addition I used to be a daily beer drinker and I no longer crave it!!!I am so excited!!! As far as getting yeast infections, I take 2 tablets of proboitics and 2 of zinc daily. Works incredibly!!! Good luck to all of you!
