OptiMSM is purified via distillation for highest purity and consistency and is an excellent source of sulfur. Although MSM occurs naturally in some foods, a significant amount of MSM is lost during the heating and processing of foods.

Not Sure and Somewhat Disappointed

Posted by HealthNut4ever on Sep 20, 2017 | Verified Purchase

This was my first time using MSM in a powder form, and so far I can't tell that I've received any benefit from it. But what is somewhat of a negative is that is does "clump up" but not to a great degree and it does break apart fairly easily, but still noticeable nonetheless. But I'd rather have that than some kind of added anti-caking additive like some other brands do. I'll update after I've finish the entire container, using as directed in my protein-nutrient shake in a Blender bottle.

Thanks for your feedback!

I definitely feel a huge difference in recovery time after being sore for a little bit, it also made my nails hard enough to actually grow for once. Awesome product!

Thanks for your feedback!

tough lesson here

Posted by iHerb Customer on Jul 31, 2017 | Verified Purchase

I bought this to help with overall skin health and got burnt so badly. I reacted in a couple of days after using this powder and was blaming all the other new products I introduced to my skin regime. I broke out in tiny bumps all over my face, neck, arms, thighs. It was itching so badly for me, I had to see a doctor for medication. I read up a lot about MSM before and even more so after the rashes and I figured it was the detox symptoms. So after I recovered, I went back to it, using only one scoop once a day and up it to 2 scoops after a week of no reaction. No allergy so far. Not sure if there are any improvements to nails/hair though, shall continue and see.
