Nice for skin + reducing pains in muscles and joints

Posted by 5610368941865173409 on May 20, 2016

I used MSM for a long time and also minimum 1000 mg per day in the morning (allways with vitamin C) and never before I have such a nice skin and never befor my pains in joints were lower. But some days (maybe 10 days) after I started to use this one MSM I have better skin and less muscle and join pains. And at the same time I did not have any problems in my stomack, no gas and no discomfort there.

I don't think I had the time to take it and really see the effect, but so far it's seems pretty good!

Excellent product, would recommend. My mother takes a while ago and this supplement is being nice to her, and now my brother also started taking for sure will do very well for him too. Excelente produto, recomendo. A minha mãe já toma faz um tempo esse suplemento e está sendo ótimo para ela, e agora meu irmão também começou a tomar, com certeza fará muito bem para ele também.
