Significant Other Liked It a Lot

Posted by Reviewer2237173 on Jun 13, 2011

I had high expectations based on reviews, and it was not bad, or deleterious. Might have had some slight effect. The other person in the household found it indeed enhanced mental acuity and was highly indignant when I was not planning to order another bottle immediately to have as a spare. I will be ordering another one this week and all will be devoted to that person's use. Note: A brand that featured the patented or trademarked Opti-MSM, ordered at the same time as the P.S. reviewed herein, was extremely excellent; very effective for BOTH of us.

Clearer thinking

Posted by Reviewer2755142 on Nov 11, 2010

After using this product for few weeks it feels like its easier to concentrate and my thoughts are clearer than before. Not the cheapest product but i will keep testing it for few months to see the real value.

Still under evaluation

One of the 100 mg pills seems to help me stay alert, in addition to other supplements. The test will be when the bottle gets empty and I am without. So far it helps.
