Bless you Cora, I asked the identical question a couple of weeks ago
and the only reply I got was a 'one liner' that wasn't terribly helpful.
I did get another reply on where to get it economically - "Animal feed store", 
so
I'll give that a go first.  (I'm from Brisbane Australia, so US suppliers would 
only be considered
as a last resort due to the problems of time delay & custom's problems)
Now, all I've got to do is find some MSM and then get the correct amount to mix 
with
CS for skin & internal use - for human use!?  Can you help further?
Thanks, Rob

  Dear Frank," MSM (methyl-sufonyl-methane) is a special biological sulfur 
found in all plants, soils, fruits, vegetables, fish, poultry, eggs, meats and 
milk. It is organic sulfur, a naturally occurring compound in the human body. 
In the purified form, it is an odorless white crystal with a slightly bitter 
taste. "  For more information see research on the website 
www.puresmsm.com/details.htm.  There are lots of other sites, e.g. 
www.health-n-energy.com/msmprod.htm  and on the excellent site Liz just 
recommended ( in the articles):
  www.familyhealthnews.com/   That should give you some to start with. 
Sincerely, Cora
