iHerb Customer Reviews

Excellent product!

Posted by iHerb Customer on Aug 13, 2011 | Verified Purchase

I have used this product for a long time now and get results that are measurable. It helps keep pain and allergies under control and sleep apnea is a thing of the past. There is a book called: The Miracles of MSM. Biological Sulpher is something we miss from our diets due to food processing and less egg consumption. However, it is a necessary part of our nutritional needs. Give it a try and measure your own results. It works!

Thanks for your feedback!

We Love this and brought a bottle for husband's friend. Me and husband believe in MSM. This seems to work stronger than the powder one I had. Plus the poweder one is bitter to drink. My hair is really long for a 52 year old lady who is going through menopause. Also this keeps me squatting and beding pretty good.

Thanks for your feedback!
