  • The best MSM supplement anywhere

  • Featuring TruFlex MSM for the ultimate joint support*

  • Delivers a potent 1,500 mg MSM per tablet to nourish cartilage, ligaments and tendons*

The answer to your joint health concerns may be as simple as three letters: MSM. They stand for methyl-sulfonyl-methane, an organic form of the essential mineral sulfur. Sulfur is important because the body needs it to maintain vital tissues like cartilage, ligaments, tendons and skin.* Although MSM pills can be used to promote digestive health and aid the body’s ability to adapt to stress, the most popular use for MSM appears to be to support joint health. Swanson Ultra MSM tablets deliver 1,500 mg of biologically active MSM for easy assimilation.

MSM is rated 3.8 out of 5 by 78.
Rated 3 out of 5 by from Great product, but. . . . the 1500mg tab is way big.. . really difficult to swallow. Next time I"ll get the 1,000 mg caps, as I usually do.

Rated 1 out of 5 by from Too big I don't normally have trouble swallowing pills but I can NOT get these down. I have ended up having to chew them which is really icky. I will never buy these from Swanson again.

Rated 1 out of 5 by from Good for horses I put 'Average' for everything other than Satisfaction and Overall Rating because, as the title suggests, horses are probably the only animals that could swallow them. I tried several times and almost choked to death because they got stuck in my throat and even when I was able to get them down, they stuck at the top of my esophagus. Then I used a razor to cut one in half. Never do that! The half was still rather large but had a hard, sharp edge that felt like it was cutting me. Finally I tried to crush the other half with a mortar and pestle and mix it in some applesauce but even some small pieces seemed to cut. I know Swanson would probably have taken them back and given me a credit but who has time to go through all of the hassle of returning one bottle? Not me.... MSM had worked well for me in the past when I needed it for joints but that was always in powder form.

Rated 1 out of 5 by from Too big to swallow! I can swallow most tablets but these are really huge. Gagged and couldn't get it down... Sorry. might be good but not if you can't swallow.

Rated 3 out of 5 by from Pill size Pill is to large almost choked trying to take it. Should have listened to previous reviews. If you have trouble swallowing anything then don't buy these. I love Swanson Vitamins I buy from them all the time but these did not work for me.

Rated 5 out of 5 by from I have been using MSM for years and feel that it is of great help,

Rated 3 out of 5 by from Bigger than a horse pill The pills are so large i have to cut them in half to swallow. You should show the size in the information.
Date published: 2014-05-20
Rated 5 out of 5 by from About The Size I just read several reviews not liking the size. The "horse" pill breaks extremely easy. It doesn't taste bad either. I bite it a few times and let it dissolve in my mouth. Give it a try. P.S. Swanson sells it in powder form as well.

Rated 3 out of 5 by from Too big for me Wanted to like them but they were a challenge to swallow and so I went to the powder form after I used them up.

Rated 3 out of 5 by from Horse Pills I take a lot of nutrients and vitamins, these pills are so huge, that I can barely swallow them. Hate taking them

Rated 5 out of 5 by from best MSM at a great price I have used this MSM for 2 years now and I love it! This is the best MSM I have ever used.

Rated 5 out of 5 by from great product for a great price I ordered Swanson Ultra MSM for my husband . He had purchased a bottle at the recommendation of his doctor and when it ran out he asked that I find it online. I was so very pleased to find that I could purchase it on your website for almost a third of the cost of the bottle my husband had purchased at a local pharmacy. He is very pleased with the product.

Rated 5 out of 5 by from Ultra MSM Years ago my sister who is a certified nutritionist recommended these to me and I've been impressed how well they help me with flexibility in my knees. When I've dropped the ball on taking them I really notice a difference how much more difficult it is to get around. I use to think there wasn't a big difference if i took them or not, but let me tell you it does make a BIG difference! Swanson vitamins absorb into the system really well too so you always get your money's worth.

Rated 3 out of 5 by from Huge Tablets These are a good strength and it is convenient to take two a day to get 3000mg, but they are really big to swallow. I don't have problems with any supplements and can take several at a time, but these have to be swallowed separately and can definitely be felt going down.
Date published: 2013-04-24
Rated 2 out of 5 by from Horse pills This item should come with a warning. The size of these pills are what you would call horse pills. I tried swallowing one and was afraid it would get stuck in my throat. I tried using a pill cutter to cut the pill in half and it still was not so easy getting it down.

Rated 5 out of 5 by from Best value I've been taking msm for a year now and my hair has been growing stronger and is shinny again ! Swansons msm is high quality, and that is what matters most to me.

Rated 5 out of 5 by from Convenient It's hard to keep up with all the things necessary to enhance our generally poor diet. Sulfur is high on the list of "missing" or "insufficient". MSM is an easy way to get there. I don't have to eat so many onions! It's helping me. I do wish the pills weren't as big as they are, but I'm managing.

Rated 4 out of 5 by from still thinking i started taking the MSN and I am getting convinced about it quality , so far so good
Date published: 2013-04-10
Rated 5 out of 5 by from Outstanding Product This is a really great product that takes a lot of flack from the size of the pills. Come on. They're not that big, just a fraction of the size of a mouth full of food. This way you get a significant amount of MSM with only one pill. It is very convenient and I've had good results from taking this. Try it and you'll see. It does what is claimed for it.

Rated 3 out of 5 by from Hard to swallow This pill is gigantic with edges that make it hard to swallow.
Date published: 2013-04-03
Rated 5 out of 5 by from big results in a big tab yes it is big. but I take multiple supplements all the time and I had no trouble swallowing. For those who have difficulty I recommend a chunk of banana :-) I felt I saw immediate results in skin tone and even eye clarity. now that I have entered menopause I have found swansons and their products to be a lifesaver!

Rated 3 out of 5 by from not the best for of msm MSM tablets and capsules have been used off and on for more than 10 years in my family with moderate results. We stayed with it because we weren't aware of any other form until recently when I discovered it in the organic powdered form. Since starting that form my health has shown marked improvement. The body is comprised of 4% sulphur but does not store the sulphur nor make it. I hasten to add I've made some dietary changes as well. I've searched Swanson's site but cannot find this form but it is available on line. Best of health to you all.

Rated 5 out of 5 by from I don't notice how much this product REALLY HELPS until I run out. I keep a good supply on hand all the time now.

Rated 1 out of 5 by from Too hard to digest I tried this product and it made me so gassy and unhappy. i gave it to my mom and it upset her stomach for hours.
