I have been taking MSM for the past week or so. I had heart palpitations yesterday. One thing that msm appears to do is purge the body of heavy metals. I suspect it may also take with it some of the necessary minerals that are key for the electrical signaling of the heart to function properly (like some other heavy metal detoxes I have taken before). As soon as I became aware of what was happening, I took a general overall mineral supplement and the palpitations ceased immediately. I will have to monitor this point forward. Less MSM. More minerals. For detox the key is not to take them together as then it is just sweeping out the minerals you took, rather than the heavy metals deeply imbedded in fat and bones. For detox it appears there needs to be 6-8 hours in between the taking of the minerals and the taking of the msm. Hope this helps in your own research.

Could someone help. This is strange. I started talking MSM a couple days ago and after second dose had palpitations and they don't stop and have been going on 24 hours now. I stopped taking MSM after it began and its still happening. Breath is hard to catch sometimes and I do not have these but maybe 2 a month and it's usually once. My BP is spiked at times and I have always had LOW LOW blood pressure. This is really creepy. I am also getting off white sugar at the same time and using brown for 4 days. So what's going on here? Don't yang about going to a Dr. If I hadn't already I wouldn't be here. They say nothing wrong but anemia.

Karen: It souns like you are having a reaction not due to allergy, but simply from the almost unique beneficial effect MSM has in greatly increasing cell membrane porosity throughout the entire body!

As such, any toxins will be mobilized in greater amounts, and that includes any Rx drugs or their metabolites.

MSM thus has the effect of amplifying the drug dose! So you have to increase the dose of MSM slowly over several weeks, and/or do not be on any Rx drugs when you do, if possible.

Drink lots of water to aid in flushing them out.

For the anemia, you are on the right track in that it can be caused by a lack of essential minerals, which can be had from things like a complete cane sugar, as near to unprocessed as possible:

www.wisegeek.com/what-is-demerara-sugar.htm

To make demerara sugar, sugar producers press sugar cane and steam the juice of the first pressing to form thick cane syrup. The cane syrup is allowed to dehydrate, leaving behind large golden brown crystals of sugar. Because demerara sugar is not heavily refined, it has a rich, creamy, molasses-like flavor which enhances baked goods. The large grains also remain crunchy through cooking, which makes demerara sugar a great choice of sprinkled topping on scones and similar dishes which might otherwise have a uniform texture.

As such, you might want to move up from the "brown sugar", since it is merely white table sugar (sucrose) sprayed with molasses to turn it just dark enough!

Warning

MSM: Serious Side Effect

I started taking MSM for asthma. My husband takes it for arthritis and gets total relief. Unfortunately I reacted badly. I had developed high cortisol subsequent to using inhaled steroids (which I discontinued). The MSM drove the cortisol higher and I suffered an extremely high pulse rate, palpitations and insomnia. When I started using MSM I did not know of this side effect. So be warned. If you have high cortisol do not take this supplement. It can be very dangerous.

The warning you posted wasn't because of the MSM you were taking, The warning was for the steroids that you were ingesting. These drugs have been proven to be very dangerous. MSM is not a drug, it's a element.

I don't take steroids and when I started the MSM, after a week or so, it caused me problems with elevated cortisol levels. So then, How would you explain that?

Warning

MSM WARNING: I began having heart palpitations and chest tightness & discomfort after taking MSM for 3 weeks. It did help with hip pain but I had to discontinue it because of side effects. This forum is excellent! I'm glad to know it wasn't just my imagination & that other people have had these side effects.

I have used MSM powder(Doctors Best) two periods. I started with a small dose 1/4 teasp to 1 tablespoon.

It helped my back pain but what really scared me off was excess hairloss and PMS. I´m not kidding, I lost both periods on MSM half of my hair. I was really sceptical it was MSM what was causing those, but had to believe since it happened twice.

I created very sore breasts and I act like a maniac before menses so I had to get rid of MSM.

Now I´d like to know, since there is so little information of MSM and women hormone balance, what is actually causing this? My own opinion is that women with oestrogen dominance suffer the most of MSM. MSM might somehow decrease progesteron levels on pre-menopausal women. I found earlier a link about the progesterone levels and MSM, but I lost it.

Do you have any information about this?

I also saw hair loss but then I saw regrowth of what appeared to be thicker strands. I think MSM is a serious nutrient we do not know enough about & it appears to work differently in everyone.

I've also had an extreme skin reaction (itchy rash that looked like psoriasis on lower arms and legs) when taking MSM. And yes, MSM seemed to be the culprit, since I was taking nothing else new; and when I stopped it, the itching stopped immediately and the rash gradually faded. Would like to hear from others who experienced a similar reaction? It's wonderful to read about the advantages of supplements, but it would also help if we take the time to report setbacks as well. Thanks!

Better But With Side Effects

I have been taking MSM for over a year now and had some symptoms of rash(not as bad as what you describe) and hardening of my lymph glands and ducts when I started taking it. It is a side effect of MSM but is probably due to your system releasing toxins. I lowered dosage and continued taking until symptoms went away and then began increasing dosage. I currently take 24 grams/day split between morning and afternoon(215 lb bodyweight). It has worked well for my asthma, joint swelling, and pain. I was worried I would need another knee surgery but don't think it will be necessary for the time being. Make sure you are buying very pure crystals so you don't have other fillers that could cause problems.

Ann, Can you or anyone else offer a little more reassurance about the side effects of MSM? I started using it in the powdered form about a week ago. The label suggested 1/2 tsp. In 8 oz. of water. After about 2 days I noticed a mild rash on my arms and stomach. By day 4 the mild rash became severe and also spread to my thighs and backs.

It's late spring and I first suspected flea bites, but our pets have been treated and my husband had none of these little red marks. After racking my brains I realized the only new thing I'd introduced into my diet or environment was the MSM. On day 5, I stopped the MSM and the marks on my back largely went away. Those on my thighs and stomach persisted; perhaps they shrank slightly.

To test MSM as the culprit, on day 6 I took the merest pinch of it -- an 1/8 of a tsp, if that. Within an hour, the rash on my legs and stomach intensified. It spread to my chest area for the first time. Additionally, on two spots of my stomach, the redness resembled hives more than a rash. Whether as rash or hives, btw, it itches!

I'm 49 years old, was diagnosed as hyperthyroid three years ago, and have been slowly healing myself through diet and vitamins, acupuncture and meditation. I've been off the methimazole for months and returned to my customary weight (about 10 lbs over the normal range) about a year ago. I'm perimenopausal, so my hormone levels are undoubtedly fluctuating, and what bugs me the most, health-wise, is my on-going fatigue and hand/wrist numbness (I call it carpal tunnel, which is commonly associated with thyroid problems, but I've never seen a neurologist to have it formally diagnosed. You know--money issues.)

In short, I'd love to reap the benefits that MSM seems to promise most people here on Earth Clinic, but the intensity of the rash has me worried. I've never had a skin condition before, so to be wearing a rash for a week, so to speak, is a little creepy. Others have talked about cutting back on the dosage, but to cut back on the miniscule amount of a pinch is to eliminate it entirely.

I bought what seems to be a good quality form of the powder. The brand label asserts no wheat, dairy, gluten, sugar, yeast, etc. , I. E. , it claims to be hypoallergenic and suitable for vegetarians. I bought it from a reputable grocery chain.

So...suggestions, reassurances, tales of similar experiences from braver pioneers than me, anyone?

Thanks in advance for any help provided!

I take it 2x a day and never experienced any problems. Sounds like you are allergic to it. If you want to try it again, buy another brand, and maybe lower your dosage. It's one of those things our bodies need but can't store, just like vitamin C, so doubtful you are allergic, you get it from a lot of foods you eat. It's a real basic form of sulphur that comes from the ocean if I remember right.

Rashes are a common detox symptom. I have read that MSM can initially cause detox reactions as the body purifies. In my own case, I had a headache at first, but it went away with continued use.

Better But With Side Effects

MSM is incredible... it cleared up my asthma...fixed my shoulder...helps my wifes allergies..she doesn't have to take antihystamines..... BUT ...... i started developing a red rash on my face...... red blotchy and itchy as the dickens...i stopped taking it for a week and then...the rash went away...i needed a fix on sunday as i had a heavy day so i took some more and this is thursday and i still have the rash worse then before it went away.......

i was taking two or three teaspoons a day...

I have not given up hope on it..i want to stop for maybe a month and then start gradually on it again....it does cause insomnia if you take it in the evening..it gives you great energy..i believe because you are getting a full lung full of oxygen because it clears out the bronchial passages........but that is only my theory as i suffer from asthma and this stuff really helps you breathe clearer...if feels like you are getting your money's worth for each breath you take...

i am interested in that term..i forget what they called it..but the idea of the msm flushing out the toxins..........i have been doing some reading on that and was contemplating doing the Hydrogen peroxide cleanse... and retry the msm..

i am a believer in the benefits of msm...but just to get rid of the side effects that people have.........
great page......keep the faith

Are sore gums a side effect of MSM detox? I have been noticing that my gums are sore since starting MSM.

Sore gums is due to vitamin C deficiency.. you may have already had a slight deficiency and the MSM made it worse. As you detox, you are also losing nutrients. I would stop taking the MSM, get an organic whole food form of Vitamin C, not ascorbic acid, and start on it for about a month before taking msm again. I would take no less than 2,000 mg daily and break it up as much as possible.

Seeking information and assistance on the following:

I started on MSM several months ago hoping to alleviate a trigger finger and thumb condition. I took it in the morning along with fruit and high quality Kefir that I make myself.

After some two months the trigger problem finger diminished, however one day after an increased dose of the msm I developed an inability to urinate. I stopped the MSM and Kefir and the dysuria condition abated. When I resumed the MSM and Kefir it came back. I've done this three times so I believe I have established the connection.

Now that I've been off the MSM a few weeks the trigger finger has shown up again. Please share your thoughts with me. William

One time I couldn't go and had to drive to town to get some cranberry juice.... One cup and my urine was back to normal. Now I keep cranberry tabs and extra bottles of juice in the pantry, save an expensive trip to town during the night.... Love, Joy

The Negative Side Effects of MSM​

I used MSM for several weeks. Though I was very pleased with having thicker, more lustrous hair, stronger nails, No arthritis pain and increased energy, I couldn't help but notice that I gained 14 pounds!! After continued use, I became an emotional mess, along with fatigue as opposed to energy. I stopped for a week and the weight is dropping. I want the beautiful, skin, hair and nails to continue. Is there a comparable supplement?
