I started taking MSM based on a recommendation from a friend. It really does make me feel great! I've been taking it for a little over a month and my nails are long and very strong. I’ve also noticed my hair growing faster and it seems stronger. I have increased energy. Would highly recommend!

Used this product to manage arthritis and FM. My knees used to hurt in cold weather, and now I can go out without any problems. It has helped me manage my FM so I can do things again.

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

Each tablet contains 1,500 mg of MSM. Take one tablet twice daily with food.


Yes, it is completely different from sulfa drugs, sulfites and sulfates.

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.

Through distillation.
