Broken Neck Recovery

Regarding Vet MSM.

I met a man that told me he was in a car accident a few years ago and broke his neck. A surgeon wanted to operate on his neck and the man refused. The man was told about Veterinarian MSM for human injuries and decided to try it. He told me he purchased the Veterinarian MSM at a feed store. I didn't ask how much he used but he told me that the Veterinarian MSM fixed his broken neck! I thought I would mention this on Earth Clinic.

MSM worked great for my daughter's asthma. She's doing awesome and no more inhalers. Amazing stuff. I use MSM for my allergies.


Knee Pain

I have really bad knees which seemed to be getting worse each week... I bought MSM on ebay here in Australia.. 400 gms and the cost was $20 for the MSM and $5 to send... I started on one teaspoon a day and have increased it to 2 teaspoons a day in orange juice, ( one teaspoon in each glass)... I wouldn't be able to walk if I hadn't started on MSM , as the pain was so severe.. I read the powder form is much bettr than the tablets as the tablets have fillers.. All I know is within one day of taking MSM, the pain was gone... I combine MSM with Castor oil.. The Castor oil I rub into the front and back of my knees.... It is fantastic... Look for the MSM that has some lumpy bits in it.... That way you know it has no fillers... It was the best $25 I've ever spent and the tub should last at least 3 months...


Urinary Incontinence

To Ted: Early this year I had a very bad UTI and ended up in hospital. Afterwards I had trouble with extreme urgency and thought that I would now have to rely on pads for the rest of my life. I had already been taking ACV regularly, so no obvious help there...However, a couple of weeks ago I started regularly taking MSM (500mg x 2 times daily).I was suprised on the second day after starting that I no longer had the "before and after" dripping problem. On the third day I was amazed at being able to hold on for 10 minutes instead of the usual 10 seconds. Since then I have had no real problems and no longer need to wear pads. I have an idea about why this worked for me but of course I have no proof, but perhaps the infection weakened my bladder (or kidneys) sufficiently to allow some opportunistic parasites to invade and the MSM killed them off. I would be interested in your thoughts on this. As ever Earth Clinic is a wonderful source of information and support.


Melasma

I have been suffering from melasma for about 4 years now. It's on my forehead,and both my cheeks. I have tried everything from bleaches, cosmelan to IPL. Everything is short term. Just as recent as December, 2007, I started taking MSM, vitamin C as well as applying apple cider vinegar on my face. The results are amazing. For the first time in 4 years I can actually say my face has improved and I don't mind going out without makeup. It's only been 6 weeks and I intend on using this remedy to see if it'll get even better. I do hope my experience and information sharing will help someone out there, that has melasma. Good luck!!

I have found that taking MSM seems to reduce pain from old injuries and arthritis. Also, MSM seems to add an essential nutrient to the system. It would be good to read one of the books written about this ingredient, nutritional sulphur, since it will answer many questions that people will have.

I told a friend about MSM and he started to take it, and found he felt immensely less pain in his back.

I forgot to mention regarding my neighbor and MSM applied topically, she told me that it makes her skin softer and her hair fuller. She said she just spritzes her hair and skin with her spray bottle of MSM. Another friend that uses MSM from a spray bottle recently told me that her skin had started feeling rough and the MSM spray made it feel smooth again!

Thanks for sharing what MSM has done for you. I'm 70 and years and years of bad posture has left me me lower back pain and now hip bursitis. Big ouch as my grandson would say. I have been taking a quarter of a teaspoon twice a day for about five days and am going to increase it gradually. Not sure if it's wishful thinking but I do feel I'm moving slightly better. Plus my shoulder, which has been painful, seems to have suddenly got better. So you have given me hope.

Hi, quality organic msm should only be consumed. Also, some people can have a sensitivity, mild gas and bloating. Msm does detox, which can cause heart palpitations, gas, diarrhea, headache. So start off slowly, increasing the dosage over time.

I just found this site and love it. I read all on MSM. I have been using it for over 10 yrs. I first heard of it when my Bullmastiff ripped a musle in his back leg completely in half. He could not use his back leg at all. After about 7-10 days on 1TBS of MSN a day he started using his leg a little at a time. When he began using his leg regularly I then just added a sprinkle to his water eveyday. In about 6months I noticed his eyes had cleared up. He was almost blind when I adopted him.

During this time I read everything I could about MSM and found that it does detox you among other things. If you read anything on detox you will find that it is important to go slow, after years of use of perscription drugs, and loads of other toxins we breath and eat every day it is not suprising to me that so many people had bad reactions. I also noticed that almost every one was still taking perscription drugs as well as MSM. Some of the side effects if not all of them sounded like basic detox results. You must slow down your detox. Your body was telling you it needed more water. Was it tap water? You should have several BM aday your body is purdging things out. If I were havig these side effects I would do more research on detox side effects and how to slow down and treat natually. For instance look at what happens to drug addicts. It can be life threatening! Remember more is not always better and education is the answer. I hope you all find the answers you are looking for.

Another thing to try- If you have a sick dog put MSM in a bowl about a tablespoon. Right next to his food. I use loose not caps. I have done this with healthy animals as well. But every single time the ill dog has lapped it up. I give it to all my animals birds, turtles, snakes, hedgehog, lizard, cat, dog,and tortis. Animals instinctivly know what they need. They have always taken it when offered. Good luck to all of you.


Side Effects and Warnings
Posted by Troy (Dublin, Va, Usa) on 04/26/2010

Folks, you have got to understand what detox is. A detox can do all sorts of strange things, until it runs its course. The best thing may be to go slow in the beginning. I highly doubt there could be a true allergic reaction to pure MSM. Because, it is in pretty much every cell in your body, and in pretty much every living thing on the planet. It is a very important nutrient. If you are allergic to it, you would be allergic to your own body.


Dosage and Tips

Regarding msm side effects, I've been taking this for years off and on, and what people seem to be describing are effects from the detoxification. When taken by mouth it takes a little time for your body to get used to it so it's a little bit at a time, also it's so important to drink water throughout the day to help flush the toxins out of your body. A good way to keep a low dose is to start with the capsules until you feel confident enough to use the powder to increase amounts.

I can't bear the taste of msm so I take it with mango juice to lessen the sharpness but others prefer tomato juice. Don't expect overnight wonders as it takes a body a full month at least before really feeling the effects, every herbal remedy takes a month before beginning to help you.

MSM: Headaches and nightmares and excessive thirst as a side effect but wow, almost pain free. Had pain in knees, neck, hips, wrists, elbows, and shoulder, feet, back, fingers on right hand. I can function again without pain. Been only a week and a half since taking it.

Hi ORH, it's me again! Your posting reminded me of an interesting observation my favourite Aunt espoused when I was very small. Amongst other accomplishments, she graduated with a Diploma in Horticulture, which greatly impressed me as a small boy fascinated by all things natural and gardening. I asked her why we had white bread as well as brown bread? Same for rice, flour and sugar etc. She was an environmentalist and an advocate for organics before those terms were coined in the main stream. She was a woman ahead of her time who put her knowledge into practice on the land. I admired her a lot. She famously said to me, "The companies take all the good stuff out and feed it to the pigs and we are left with the rest". I never forgot that but I should have promptly taken up shares in a pig farm I suppose!

Rachel Carlson (sp?) wrote "Silent Spring" about the same time I would guess. Oh my, we have not learned a lot since then have we??

Cheers, Michael

I've been reading all the comments about MSM on here for a couple of years now. Not to mention all the other info on line as well. I also read a book that surprisingly wasn't all that informative. You can also go to the infamous VIDEO site and find lots of useful health information.

When you first start taking MSM you WILL get a headache. That's a given. I don't know about a migraine, I don't know if I've ever had one. I had anywhere from a mild to a pretty severe.. Kind of dizzy like headache. This will pass if you can keep up with it. They say it will usually go away in about three weeks. Mine took about a month before it stopped. If you stop taking it and then start taking it again, It WILL start all over again. You can go a day or two but I would push my luck. I realize it's anoying but if you can stick it out you'll get past it.

Now the other thing is that you NEED to buy a powder. The tablets are useless. (or capsules)You would need to take the entire bottle in one day to get enough. Taking a thousand Mg once, twice, or three times a day is the same as taking nothing.

I am currently taking 20 thousand Mg a day. That's right 20,000. I take 10 thousand mg roughly 12 hours apart. When you really start investigating and reading enough on it you'll find that's the suggested amount. Most people start out really, really low and gradually work their way up. That may be a way to avoid the headaches. My theory was if I'm going to get them anyway I might as well take a useful amount and get them over with at the same time.

MSM is naturally occuring, just not as much as it use to. Like everything else. Some of these stories are a little out there as far as I'm concerned. These scare tactics just because you didn't like it or had some thing happen that you think was because of something you tried on Earthclinic are ridiculus and shouldn't even be posted as far as I'm concerned.

MSM has the same toxity as water. Meaning NONE. You can't take too much. Anything your body doesn't need will just come out in your urine. Just like water. You may find yourself going to the bathroom alot more when you first start taking it.

One more thing. I also used to buy it at a local Farm supply store down the street. 2 Lb's for about $17.00. That's half the price for twice the amount from a health food store or on line. The more I read about it the more I found out that maybe I shouldn't. The theory is that if it comes from China (this did) it is propably loaded with mercury and lead. China doesn't treat its water properly because it doesn't care about its poeple. They have horribly polluted water. Water is a big part of processing MSM and the polutants all get trapped in the MSM. I can't find a Horse/vet brand that isn't made in China. The container never says. When you call them it's like pulling teeth trying to get a strait answer. Eventually they admit it's from China. So until I find a safe Vet version I'll have to keep paying twice as much for half the amount. Or until I find that a china made brand is not neccasarily polluted.

I have been in the healing profession (practitioner, researcher, advocate) for 30 years, nothing comes close to my experience with MSM. I am so sorry it took this long to try it.

My chronic asthma gone in 3 days!! On albuterol for almost 40 years. I am in shock.

Some side effects which I consider to be cleansing symptoms. Nausea, sleeplessness and skin breakouts, but I did start on a high dose of 20 grams a day. After three weeks no more 'side effects'.

My energy has greatly increased, I feel quite euphoric every day now. The only time I had that kind of euphoria was by drinking three glasses of organic green juices a day. I think people on heavy medications, mercury fillings, toxic diet are going to have more difficulties with it, so building up from a small dose with extra vitamin C and plenty of pure water will help.

The other supplement that really helps is Vitamin D3, I take 16,000iu liquid daily, no colds for two years now and my chronic bronchitis of 20 years has disappeared.

Some years it was mild others, severe triggering serious asthma attacks. So the combination of Vitamin D3 and MSM has been miraculous for me. This great website encouraged me to try MSM. Thanks so much.

p.s. Brushing my teeth with MSM has whitened them.

I also take MSM, however, if you read the literature...it tells you not to take it after 2 pm as it may cause sleeplessness. I have never experienced anxiety. I take 4 100 mg caps in the morning and 4 at noon with no problems. It does help my arthritis and my hair and nails grow like crazy.

I've been using MSM for 3-5 months now, and only side effects so far have been that my acne healed away and pimples are gone! But it seem I've got more wrinkles around eyes, but that might only be cause I'm aging.


Arthritis

Hi Cat,

I had the EXACT same response as you when I tried taking MSM - heart palpitations and increasing anxiety and unbearable pressure on my chest when I lay down to sleep. I read that you should stop for a few days and then start again with a very small amount of MSM and work your way up very slowly. I have a giant bottle of MSM powder but have yet to try it again because m first experience was very scary. What if you roll on just the MSM gel and not swallow any? Maybe that's the key. Please let us know how it goes.


Joint Pain
Posted by Paula (Mississauga, Canada) on 11/12/2013

I totally agree that too many people aren't taking the right dosage and the right brand of MSM to see result. I was experiencing really bad headaches that were 24/7. I had low energy and I hate to say I was having trouble sleeping.

But the pain relief in my joints has been amazing and getting better by the week.

I have arthritis in both knees (bad), in both hips and lower back. I have terrible pain in both feet. (Sport injuries) Had surgeries on one foot and both knees, one twice.

I started off I thought on a low dose and increased gradually over the weeks but still suffered the headaches. I went for acupuncture 2x and got amazing relief. I will gladly suffer the detox symptoms knowing they are releasing from my body and knowing MSM is healing my body pain.

I take absolutely no medication for anything other than Advil when in dire straits. I will try anything natural and give it ALOT of time before I give up. It has been 6 weeks since starting on MSM and I am up to 8 grams a day. I plan to get to 12g. Every week I feel improvements and I am hopeful for a complete remission from my arthritis within the year with the help of acupuncture or other natural means to assist MSM to get me there.

I gotta say I love what MSM is doing for my skin, hair and nails. My hair is staying beautiful and curly and FULL when it always goes flat and pretty straight in our Canadian winter climate. My skin is hydrated and healthy for the 1st time in my whole life. This is only after 6 weeks. I can't wait to see how I feel months from now. Pain has been my mate for too long and finally I am feeling the distance from it. Give it time. Give it at least a year. You all owe yourselves that. Change the brand if you have to until you find one that works. Don"t just try one.

Distilled MSM and a reputable brand is paramount.
