Yes, it was earlier this year that it was generally accepted to be safe, up until then I hadn't been aware that it had been around for 20 years. So there have been a lot of studies on its effects.
I would have recommended the place I get mine, however they are getting to be a bit unreliable and so I'm looking for a new supplier. If you like, I'll let you know when I find one :-)
I think I would like that very much if you don't mind!
