Rated 4 out of 5 by MSM a terrific source for good health I am so happy to be one of the people in the know about MSM. It has been a joint and body body saver! May 5, 2016
Rated 5 out of 5 by MSM I have been taking MSM for man, many years. I used to buy at a discounted price from a company in Oregon. I was reluctant to switch, but found Swanson's MSM to be very good and at a better price. March 15, 2016
Rated 5 out of 5 by Great Satisfaction Although doctors told me that I should quit playing basketball over ten years ago, since I've been taking this supplement, I've been able to continue playing both softball and basketball. December 21, 2015
Rated 5 out of 5 by MSM I like these alot, easy to swallow capsules, Swanson is always the best price and value plus always super fast on shipping. I compare prices with other vitamin compnies and Swanson cant be beat! October 29, 2015
Rated 5 out of 5 by Great value I have been taking this MSM for about 1 year, and I am ordering more now. This is a great price for MSM. I also take chondroitin and glucosamine. I am 79 and my joints are in great shape, and I am almost always happy and have lots of energy. I've read lots of good things about MSM, and I believe this is good for me. October 8, 2015
Rated 5 out of 5 by Swanson's MSM MSN is a GREAT source of sulfur. Been taking this for years. Sulfur is good for the skin, hair and the joints! Bigger bottle at a great price. Thanks Swanson! August 26, 2015
Rated 5 out of 5 by MSM I have only been taking MSM for a week and a half and I already feel a big difference in my joints, July 27, 2015
Rated 5 out of 5 by This is great stuff! This product lives up to its claim. March 31, 2015
Rated 5 out of 5 by MSM Great value, quality and service. January 12, 2015
Rated 5 out of 5 by Love this product I've been taking this product for over 10 years. I'm very happy with the result and I can still perform very physical activities. Thanks. December 1, 2014
Rated 5 out of 5 by Seems as good as the (much) more expensive brands I used to pay about $50 a month for top quality MSM. I tried a cheaper brand (off Amazon) that did not work as well for me (and actually seemed to have some negative effects/sinus issues). This brand, however, seems as effective without the extreme cost. I doubled up on my purchase the last time. August 6, 2014
Rated 5 out of 5 by Ifn u looking for an economical source of sulphur August 2, 2014
Rated 5 out of 5 by Best Purchase Ever This MSM is the best I have found!! Along with malic acid and iodine supplements from Swanson I am now doing great, and feeling better than I did 20 years ago. I urge everyone to do your research on how nutrition will heal your body. Thank you so much to Swanson for great products and great value!!! June 29, 2014
Rated 4 out of 5 by Everyone needs additional help with their body chemistry to improve well-being! June 14, 2014
Rated 3 out of 5 by Misleading Dates Was assuming that the dates on Swanson products were expiration dates like other companies products. It seems that they are MFG dates. Why would I give a darn when it was made. I want to know when it is good till. March 21, 2014
Rated 5 out of 5 by This Distilled MSM is the Best I can't do without this! I have gotten the best results from MSM, more than any other supplement. And distilled is supposed to be the purest. I'm very sensitive, or allergic to ingredients---but I don't have a problem with this kind. I HAD to work into it slowly.... it's just part of the process of taking msm, especially if a person is sensitive or trying to detox. March 5, 2014
Rated 5 out of 5 by big helper after reading about it function and benefit i keep taking it, have to crush it before but know how much my joints appreciate it. January 19, 2014
Rated 5 out of 5 by Great! Truly effective Best deal i have found for this amount and quality December 30, 2013
Rated 4 out of 5 by msm I think this product helps with my overall well being. Thanks. December 24, 2013
Rated 5 out of 5 by MSM Caplets I have been purchasing this product for years because of its high potency and excellent price. November 24, 2013
Rated 5 out of 5 by MSM This product is very helpfull for my joints November 20, 2013
Rated 5 out of 5 by MSM Rocks Due to governmental regulations for dietary supplements, we cannot accept any reviews with medical or disease claims. I copied the above from Swanson's website. It is a shame because I would love to share how MSM has tremendously helped my daughter. I hope that I can at least say that it has made her ovulation & period much easier to deal with. This month is the 1st time in a while she has gone to school during ovulation. I also put her on a gluten free diet & cut out all dairy except eggs. I just reordered a 2 month supply! A million thanks Swanson! November 13, 2013
Rated 4 out of 5 by Warning Causes Headaches I loved this product but just beware that it can cause headaches. This has nothing to do with the swanson quality of the product its just MSM in general. So I would recommend you start at a low dose and work your way up. September 20, 2013
