Rated 5 out of 5 by from MSM Review I started with capsules. After two months I switched to the powder. MSM is one of the best moves I've ever made. Swanson's user friendly prices helps.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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!!!

Rated 3 out of 5 by from 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.
Date published: 2014-03-21
Rated 5 out of 5 by from 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.
