Hi jojo
I have bad news. MSM gave me yeast infection! I took it for two days and had to stop. The very first day, after 1tsp, I started to have problems. The second day, I took 1tsp in the morning and 1tsp in the evening - the problems got much worse.
I started getting better after about 12hs of taking the last tsp of MSM.

I've done a little research online and found out that MSM cures some women while it causes other women to get yeast infection...very weird...Ah, I am back where I started: looking for a cure.

Thank you for trying to help us.

Jojo, I am really sorry that I missed this post!

I'm not sure of the quality but the site advertises 100% pure food-grade and I have enjoyed everything I've ordered from them. I am using the crystals now. I'm only up to 3 tsp a day for now. But I'm already noticing a lessening of the miserable side effects of the psoriasis that I'm suffering from. I am writing a thread in my journal about MSM so I can find all the information in one place in the future. Once I have my head wrapped around all the information I'm digging up, I will post it in the supplements forum.

I need to add to my previous post. I am not entirelly sure my yeast infection was caused by MSM...I tend to get it every month before my period and this was one of those times...So don't know anything anymore.
