I do have MSM crystals but keep forgetting to take it.
However, after receiving an email regarding MSM and cardiovascular health, followed the next day by Earth Clinic's email about MSM's benefits, I have resolved to start taking it twice a day (with Vitamin C to enhance the effects).
I now leave the jar on my kitchen counter as a reminder – I'll see if that works.
The information about keeping our heart healthy was from a company that sells MSM but their information is free and they do provide references and sources at the end of the article if you want to do some more research.
Speaking of hearts, Happy Valentine's Day tomorrow!
