I had to change my vote from just great back and joint pain benefits after freebasing on the Nioxin thread and realizing I've been seeing other benefits as well. I re-evaluated some changes since I started taking Bluebonnet MSM.
The nutritional info lists 1/2 TSP at 2,600mg (884mg organic sulfur), I take roughly 1 TB per day which comes out to 15,600mg MSM (5,300mg organic sulfur).
My nails and hair always grow long and strong but I hand wash a lot and get constant chipping and peeling and let my hair get way too dry and get breakage as a result.
Results: I still handwash but now my nails are hard as steel, no peeling. My hair has virtually no breakage now and strangely almost no shedding. I thought it was just the KCKT but maybe I'm wrong...The hair growth is probably normal, I'll keep checking.
My eyebrows are much more full than usual and grow much faster than usual as well as other body hair (hmm...), my skin is still doing very well with good cell turnover despite my crap diet which is part of my 2012 resolution.
I buy my 8oz of powder from WF or Bell Bates on Reade Street in Tribeca for about $9
