I really like this MSM. I have been taking it for two weeks now and I am more flexible than ever. My whole body feels great. I add it to my water each day, and also to my smoothies. I have also added it to distilled water and used the solution as an eye drop. My eyes feel amazing and my brand new. My vision got a boost, I love it!

I have had allergy problems since I was five. I have taken every antihistamine on the market and none of them have helped my allergies as well as MSM. I take 3,000 mg twice a day with 500 mg of Vitamin C. Since starting this routine, I have had more energy and a significant improvement in allergy symptom relief.

I love the results of adding MSM to my daily routine. It has helped me not only with joint relief, but has brought relief to some of my skin ailments. I believed I was deficient in sulfur after moving to a new location. This dissolves quickly into the water and has very little taste. I have purchased more and gifted it to a friend that was having terrible shoulder pain and she found relief! She is now a faithful user of this product as well. Recommend this product for quality and results!

MSM manufacturing magic.

We chose American-manufactured OptiMSM® for our formulas because it is the purist and only form of MSM on the market that is GRAS-designated (Generally Recognized as Safe). It achieved this designation by adopting a four-stage process to separate impurities including heavy metals and other contaminants. Each batch exceeds the United States Pharmacopeia (USP) monograph standards for MSM, and is validated by testing in independent laboratories.

Suggested Use

Contains 8.8 oz (250 g) of MSM per container. We recommend mixing three level scoops into 8 oz of juice (or another beverage of choice) daily.


Yes, once a jar of MSM powder has been opened, it is susceptible to clumping due to humidity. Again, the solution is to simply shake the jar until the clumps disappear.

MSM is an organic substance that contains bioavailable sulfur. MSM contains about 34 percent elemental sulfur. 1000 mg of MSM contains about 340 milligrams of elemental sulfur.

MSM is not commercially available as an extract from plants or other natural materials. OptiMSM is made by converting DMSO (dimethylsufloxide) which is an organosulfur compound (organic compound containing sulfur), to DMSO2.
