Health Benefits of MSM

MSM (methylsulfonylmethane) is an organic sulfur compound and one of the most popular natural supplements for joint health, allergies, inflammation, and skin rejuvenation.

Known as a natural source of bioavailable sulfur, MSM supports collagen production, tissue repair, and cellular detoxification.

It’s used by both humans and animals to reduce joint stiffness, promote stronger hair and nails, and even alleviate chronic pain. However, while many find MSM transformative, some experience uncomfortable side effects—making proper dosage and a gradual start essential.

⚠️ Important Medical Disclaimer

This article is for educational purposes only. Consult your healthcare provider before starting MSM, especially if you are pregnant, breastfeeding, have a cardiovascular condition, or take prescription medications (especially blood thinners). MSM can cause detox-like symptoms and must be introduced gradually.


What Is MSM & Why Sulfur Matters

MSM stands for methylsulfonylmethane. It’s an organic sulfur compound naturally found in fresh fruits, vegetables, and grains. However, MSM degrades quickly with processing and heat, which is why many people turn to supplements.

It is closely related to DMSO, another sulfur compound. In fact, MSM is a metabolite of DMSO, but it is more stable, has no odor, and is a much more common dietary supplement.

Why Sulfur Matters

Sulfur is the third most abundant mineral in your body. It is a critical "building block" for:

  • Collagen & Keratin: The proteins that make up your skin, hair, nails, and connective tissues.
  • Joints: It's a key component of glucosamine and chondroitin, which form cartilage.
  • Detoxification: It is required to produce glutathione, your body’s master antioxidant.

A deficiency in dietary sulfur may contribute to brittle hair and nails, joint stiffness, and poor immune function. MSM simply provides a stable, bioavailable source of this essential mineral.

Historical Note: Ancient cultures valued sulfur-rich hot springs for pain relief and skin health. Modern MSM supplementation offers a concentrated, odor-free form of that same mineral benefit.


Top Health Benefits of MSM

MSM's benefits stem from its ability to donate sulfur, reduce inflammation, and fight oxidative stress.

Joints & Pain Relief

  • Reduces inflammation and pain in joints, muscles, and connective tissue.
  • Improves flexibility and mobility, especially in arthritis.
  • Often used by athletes for sports injuries, back pain, tennis elbow, and muscle soreness.

Skin, Hair & Nail Health

  • Provides the sulfur needed to boost collagen and keratin production.
  • Promotes faster, stronger hair and nail growth (a very common user report).
  • May improve skin elasticity and hydration.
  • Used both internally and topically (as a gel or cream) to help calm rosacea, acne, and melasma.

Allergies & Respiratory Support

  • May help relieve symptoms of seasonal allergies (like sneezing and itching) by reducing inflammation and helping to stabilize mast cells (which release histamine).
  • Some users report easier breathing and relief from allergy-induced asthma symptoms.

Digestive & Gut Health

  • Soothes inflammation in the gut lining, which may benefit conditions like IBS and ulcerative colitis.
  • Can improve bowel regularity; many users report it helps with chronic constipation.

Dosage & How to Take (Start Here)

This is the most important section. Nearly all negative side effects come from starting with too high a dose.

Quick Dosing Guide

  • Rule #1: START LOW, GO SLOW. Do not start with a full teaspoon.
  • Starting Dose: Begin with 1/4 teaspoon (about 1,000 mg) of MSM powder in water, once a day in the morning.
  • Increase Gradually: Stay at your starting dose for 3-4 days. If you feel fine, you can slowly increase to 1/2 teaspoon, and later to 1 full teaspoon (4-5 grams).
  • With Vitamin C: Take MSM with 500-1,000 mg of Vitamin C (or in water with lemon juice). Vitamin C helps your body use the MSM to build collagen.
  • Therapeutic Dose: Many people with chronic pain or inflammation work up to 1 teaspoon (4–5 grams) once or twice a day. Doses vary widely.
  • Powder vs. Capsules: Powder is the purest and most economical form. Capsules are convenient but may contain fillers and are less cost-effective at higher doses.
  • Timing: Take MSM in the morning. It can be energizing, so avoid taking it late in the day as it may cause insomnia.

MSM for Pets

MSM is widely used in veterinary health for joint and allergy relief. It is popular for horses with sore muscles and for dogs and cats with arthritis, hip dysplasia, and itching from allergies.

  • How to Give: Start with a tiny dose mixed into their food.
    • Small dog or cat: Start with a tiny pinch (less than 1/8 tsp).
    • Medium/Large dog: Start with 1/8 to 1/4 tsp.
  • Some owners dissolve 1 tsp in a *second* water bowl, allowing the pet to self-select.
  • Caution: If your animal shows restlessness, anxiety, or hyperactivity, stop or reduce the dose.

Side Effects & Safety

Most side effects are a sign of detoxification or starting with too high a dose.

Common "Detox" Symptoms (Usually Mild)

These may occur in the first few days. They are a sign to reduce your dose and drink more water.

  • Headache
  • Nausea or mild digestive upset
  • Fatigue
  • Skin breakouts or a temporary rash

Signs of Taking Too Much

These are more serious reactions. Stop taking MSM and consult your doctor if you experience:

  • Heart palpitations or a racing heart
  • Anxiety or panic-like feelings
  • Insomnia or restlessness

Who Should Use Caution

  • Blood Thinners: MSM may have a mild blood-thinning effect. Do NOT take it with warfarin (Coumadin) or other prescription blood thinners without your doctor's approval.
  • Pregnancy/Breastfeeding: There is not enough safety data. Avoid use.
  • Sulfa Allergy: See the FAQ below. MSM is generally considered safe, but talk to your doctor first.

What Users Report: The "Hidden" Testimonials & Real-World Feedback

Beyond clinical summaries, user testimonials from Earth Clinic, Amazon, and health forums paint a detailed picture of what to expect. This feedback often highlights surprising benefits and specific side effects that articles don't always capture.

The "I Took It for My Knees, But..." Surprising Benefits

This is the most common theme in MSM reviews. People take it for one reason (usually pain) and are shocked by other positive effects.

  • Hair, Nails, and... Eyelashes: This is the #1 reported "side benefit." Users who don't even care about beauty report, "My nails stopped peeling for the first time in my life," or "My hairdresser asked what I was doing because my hair is so thick." Some even report longer, thicker eyelashes and eyebrows.
  • The "MSM Glow": Users often describe a "glow" or "plumpness" to their skin. They report fine lines (especially "crow's feet") seem softer and that their skin looks more hydrated and less dull.
  • The Allergy Blocker: Many long-term users report that their seasonal allergies (hay fever) "just didn't show up" or were 80-90% reduced. They feel it "calms the histamine response" better than anything else.
  • The "Clean Energy" Boost: A very common report is a boost in "clean" energy. Users describe it as "not jittery like coffee" but a "clear-headed, steady energy" that wipes out their afternoon "brain fog" or slump.
  • Constipation Relief:** Thousands of reviews, especially for MSM powder in water, state it's the most effective, gentle remedy for chronic constipation they've ever tried, often working better than fiber or laxatives.

Deeper Feedback on Joint & Pain Relief

Testimonials for pain go beyond "it helped."

  • The "Creak" Factor: Users often say, "I stopped 'creaking' when I get out of bed in the morning," or "I can finally kneel in the garden again without paying for it for two days."
  • Athletic Recovery: Athletes and gym-goers report that their "post-workout recovery time is cut in half" and that muscle soreness (DOMS) is significantly reduced.
  • Timeframe:** Reports on pain relief vary. Some feel a difference in "as little as 3-4 days," while others say, "You have to stick with it for 2-3 weeks to feel the full effect."

A Deeper Look at Side Effects: "The Detox Phase"

User reports on side effects are very consistent and almost always linked to starting with too high a dose.

  • The #1 Warning: Palpitations & Anxiety. The most-reported "scary" side effect is a "racing heart, heart palpitations, or sudden anxiety." Users who experience this consistently report they "started with 1/2 or 1 full teaspoon," which was too much. This is the main reason for the "start low, go slow" advice.
  • The "Detox" Rash & Headaches: Many users report a temporary headache, fatigue, or an "itchy rash on their torso or arms" in the first week. This is widely believed to be a detoxification reaction. The universal advice from other users is: "Don't panic. Stop taking it, drink tons of water for 2-3 days until it clears, then restart at a tiny dose (like 1/8 teaspoon) and work up."
  • Digestive Upset:** At higher doses, some report "loose stools" or "gurgling," which usually levels out as the body adjusts or the dose is lowered.

User-Reported "Hacks" for Best Results

  • "Take It Like a Shot": The powder's taste is famously bitter or metallic. The #1 user hack is to "mix the powder in 1-2 ounces of orange juice, lemon water, or grape juice. The small amount of liquid masks the taste, and you take it like a shot."
  • l"Always with Vitamin C": A near-universal rule in the MSM community. Users feel it "activates" the MSM and is essential for the collagen (skin/joint) benefits. Most mix their powder with juice (for the Vitamin C) or take a 500mg-1000mg Vitamin C capsule at the same time.
  • "Morning Only!": Because of the "clean energy" boost, thousands of reviews warn: "Take it in the morning with breakfast. If you take it after 2 PM, you might be staring at the ceiling all night."
  • "Powder is Better than Pills": The overwhelming consensus is that the powder is purer (no fillers), far more cost-effective, and easier to titrate (adjust) the dose, which is critical for avoiding side effects.

Frequently Asked Questions (FAQs)

Is MSM the same as a "Sulfa" allergy?

No. This is a common and important confusion. "Sulfa" allergies refer to a specific class of antibiotics (sulfonamides). MSM is an *organic sulfur* compound, a natural mineral. The two are chemically different. Most people with a sulfa allergy can take MSM safely, but you should always consult your doctor or allergist first.

How long does MSM take to work?

It varies. Some people feel pain relief within a few days. For skin, hair, and nail benefits, you need to be consistent for at least 3-4 weeks to see noticeable new growth and changes in texture.

Is MSM powder better than capsules?

Powder is generally preferred because it's purer (no fillers, binders, or anti-caking agents) and much more economical, especially at therapeutic doses (1-2 teaspoons a day). Its taste is just bitter, not offensive, and is easily masked in water with lemon or a little juice.

What's the difference between MSM and Glucosamine?

They work well together. Think of it this way: Glucosamine/Chondroitin are the primary "building blocks" for cartilage. MSM is the "anti-inflammatory" and "sulfur donor" that helps reduce the pain and swelling, allowing the body to repair the joint.


Where to Buy

MSM is inexpensive and widely available. Look for 99.9% pure, distilled MSM with no additives or fillers.


MSM is one of the most versatile and affordable natural supplements, providing essential sulfur for joints, skin, and connective tissue. When used properly—starting slowly and monitoring for sensitivity—it can offer powerful support for both humans and pets.

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.

For nearly forty years I have had a problem with reactions to animal dander (horses, cats and some dogs).

After taking 1 tablespoon of msm 3 times a day they ceased!

I went through some detox reactions - headaches and mild flu like symptoms - lots of emotions surface, predominantly tears, but each episode passed quickly. It seemed with each emotional release my reactions to animal dander decreased so I embraced that by watching plenty of sad movies to speed up the process!

Msm has been life changing for me.

I had said here a while ago that I wanted to try MSM for my allergies, hoping it would do something for my lower back pain as well but unfortunately, after almost 5 weeks nothing happened. My allergies are the same as before, sometimes itching eyes and throat and sneezing, my back pain has actually got worse. Since yesterday I am really worrying but I don't want to go to the doctor yet. Before I started taking it I read a book and I was convinced, in the meanwhile, because I had a friend coming over from the USA I ordered another book which was a lot less expensive over there to be sent to his home address. I am now starting to read it and really, it feels like a bad joke! Is it as good as they say but it just didn't work with me? It seems to do wonders for so many people.....

Right now I really fear for my back! I am 53, not too old yet but feeling like an old lady! The pain started almost 5 years ago when we got a foam mattrass, equally for me and for my husband so we thought the mattrass was to blame. 18 months ago we decided to go for one twice as expensive. My husband didn't want foam again but I felt comfortable in this one and too bad he didn't insist he didn't want it. He still has problems but I am far worse than he is especially because during the week I tend to read in bed for a bit in the morning. If I sleep on my back it is even worse. The only thing that seems to have got better with the MSM is my digestion, nowadays I eat and I never feel full.

Hi Francisca - Sorry that MSM didn't help your allergies. It was one of the few things that worked for me.

However, in Dr. J. Wright's newsletter (he operates a clinic in Washington state), he recommends the following for allergies:

There are several vitamins that can help reduce -- and in some cases eliminate - inhalant (i. E. , environmental) allergy symptoms.

Vitamin C is always the first vitamin to try. It's been shown to reduce bronchial, nasal, and sinus allergy symptoms. I recommend the "bowel tolerance" quantity of vitamin C. Basically, this means using as much vitamin C as possible, every three to four hours, without causing gas or loose bowels. For some people, this is 1, 000 milligrams (1 gram) three to four times daily; for others, it can be 4 grams or more three to four times daily.

Some people with inhalant allergies also find that taking 1, 000 milligrams of pantothenic acid (vitamin B5) along with vitamin C three to four times a day helps relieve their symptoms even more than vitamin C on its own.

I don't know if that is something you might consider trying. Good luck!

Hi Bess, thanks so much for all the information, I really appreciate! Yes, quite odd the MSM didn't help... I am taking three half teaspoons three times a day so that would make 7, 5g a day but there were no changes at all, not for my back pain either..... I feel rather frustrated! I am now reading "The power of MSM" by Earl Mindell and he advises taking MSM together with Vit. C, quercitin and pantothenic acid for allergies so a bit like what I read in your post but adding MSM and quercitin. In the past I have taken quercitin but not in this combination although, if I am not wrong, it was a complex with pantothenic acid but again it didn't really solve my problem.

Right now, together with the MSM powder (I buy it in the UK because here I only find tablets and even there they don't seem to sell crystals) which is almost finished I take 3 times a day 1g of Vit. C and also Vit. E. For the pain I might try Hyaluronic Acid which I can buy in the UK (we are going there soon and I always visit the same health food shop). But I am also going to the doctor tomorrow, something I dread doing, because I stopped taking the anticonceptive pill and the fact that the pain now is worse might be a consequence of me missing some hormones, that has always given me back pain in the past! The troubles of menopause, I suppose.....

Taking MSM has helped my chronic sinus problems tremendously. I also use Colloidal Silver noise spray along with it. As for your back, I have a terrible reaction to Memory Foam. I can't sleep on it for more than a few days without having trouble breathing and racing heartbeat. I only buy pure, natural latex mattresses now. The sleeponlatex.com mattress I never woke with back or shoulder pain and always slept on my back. I'm now trying a hybrid latex and spring mattress, Sleepzzz. It uses 100% wool as the fire retardant so no toxic spray. Both brands of mattresses are as non-toxic as you can get. Don't underestimate the importance of what your mattress contains.

I have had seasonal allergies for the past 6-7 years. Earlier this year I read about how MSM can alleviate the symptoms of seasonal allergies, so I decided to give it a try. The allergy season was just starting and I could feel my eyes getting a bit itchy.

I started taking 1000 mg of MSM and within 1 hour I was feeling better. It works as well as any OTC allergy medicine with out the negative health effects. As a matter of fact it is supposed to have beneficial health effects. I now take 1000 mg of MSM twice per day and have not had any more symptoms of allergies.

I love this stuff.

BETTER BUT WITH SIDE EFFECTS

I began after using the MSM gel for my arthritic knees and thumb. I experienced almost immediately within 2 days better movement and no pain in my knee, hip and thumb. On the 4th day I even walked a mile with my grandchildren which I was unable to do since April of 2014. My allergies were gone, and so was brain fog, I felt fantastic and could move around and be normal but? I began experiencing heart palpitations on day 5 and felt quite uneasy. They continued until I became frightened. I wrestled with feeling fabulous or heart problems as I do not like feeling disabled at 56, but have discontinued the product. This morning my walking is worsened, the pain is coming and my allergies are terrible. So extremely sad. I was taking 1/8 teaspoon once a day and had increased to 1/4 2 times a day. Any ideas?

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.

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.

Dear Robert Henry,

I happened to be near a tractor supply store today so I popped in. I wanted to get some MSM to try out. I know you say you get yours at the farm stores. As you said, this brand they sold has only MSM. I noticed online that powdered MSM costs twice as much and at least one of them had extra ingredients.

I asked an employee if they had MSM for horses. (I didn't mean to imply that I had a horse, but I know that would help them know what I was looking for.)

When I left, she said, "Good luck with your horse! " I decided not to try and explain why I wanted it and that I didn't even have a horse!

I have had to explain to several children why I have a horse supplement on the kitchen counter, though. It has a picture of a horse and everything! ("We are not getting a horse." "It's for me, actually.") I got some raised eyebrows but they didn't get too excited. They are used to me always trying something new around here. :)

I may give some to my dog, too, as a preventative. His breed is prone to hip problems.

Always something new to learn about, isn't there?

MAMA,,,,,,,, at our Co-Op there are several brands of MSM, but only one is 100%. My Tractor Driver picked up the 99% and we returned it for the 100%. Like anything else you have to read the labels.

You are right about supplement suppliers raising prices as the the demand goes up. Like Big Pharma, they will " sock it to you baby". I stole a diddy from my an ole boss back in '61 when he told me that "all companies are " chicken sheet. The only difference is the degree". Then, I thought that was a terrible thing to say, but 56 years have passed under the bridge, and I now agree.

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

Never take MSM before bed for the simple reason that it gives you energy! The best book out there on MSM is by Dr. Jacob, The Miracle of MSM. He is the foremost informative author on MSM. I just started taking MSM for my painful arthritic knees after reading the book 1st. I am 48 and have been suffering for years. I have had major surgery on one and scopes on both. I get Monovisc injections and it does help and makes my life easy but I am looking for more help and I hope MSM will be it. I must say right off the bat that applying MSM cream topically to my knees and legs and face has had amazing results.

I have suffered from dry skin ALL my life and in short order my skin is healthy and moisturized like I have never experienced. I walked down some stairs after a week on MSM and couldn't believe the ease I felt in more than a decade. Still experiencing pain doing simple things like walking but I am hopeful and will give it a year. The longer you have lived with your trouble it will take longer to benefit from MSM (as the book states) or any other remedy.

I was suffering arthritis in my right knee, pain so severe I began wishing for amputation. At a friend's suggestion I began taking MSM, 1 heaping tablespoon with each meal, and 1 @ bedtime. It tasted terrible, but the results were great. The pain has completely vanished, and it has been more than a year since I stopped the regimen!

MSM for arthritis- MSM purchased from the veterinary shop or stables is cheap and it works like a charm. I have been taking the powder (very bitter!!! ) for 6 months and my arthritis is cured, although it is an ongoing remedy but the dosage is less per day.

I have been taking msm for about 6 weeks now and am amazed at the results. I was taking a high dosage of sulfasalazine for the past 3 years. I weaned myself off them in November. I can honestly say the msm has an even better pain relief than the medication.

I was taking 2 level teaspoons then increased the dosage to 2 level tablespoons until I got my joint pain under control. I am now taking a level teaspoon twice daily. This site is wonderful and I have tried many of the remedies. Thankyou all for your posts best wishes.

When I first learned about MSM from an artcle in Journal of Longevity about 15 or more years ago, I read that one of the doctors treating patients with it had been taking the race horse dose for years to see if any adverse side effects occurred. Supposedly at the age of 75(at time article was written), he still had a full head of dark hair and was still teaching medicine as well as practicing medicine.

I started off at the race horse dosage myself and continued at that dose. I wasn't aware that it was doing anything until one night I noticed it was raining and my joints that had always warned me that weather change was coming, hadn't warned me! I took MSM daily for several years at the large dosage for race horses.

I have to admit that I have gotten quite lax with it over the last few years, but my knees are giving me twinges now and then. When they do I go back on the large dose daily until I forget I had the problem, and then get slack again.

MSM supposedly has both antiinflammatory properties as well as cell regeneration. You can find a lot of information on line about MSM. There is also a book written by the doctor who wrote the article that let me in on the MSM, and I believe Dr. Jacobs (the one taking racehorse dose for years) co-authored the book on MSM. You should be able to find it in any bookstore.

I have had Psoriatic Arthritis since I was 10 years old, & one of the worst symptoms I've had for 38 yrs now, is daily shooting nerve pains in my extremities.

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 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.
