That's good info, but it doesn't explain the differences between Mitrolan, Fibercon, and Equalactin.See, Fibercon has a shell which contains sodium laurel sulfate (SLS). SLS causes me canker sores and bad dry skin, so I avoid products with that ingredient. The people at Fibercon claim that the SLS is "inactive." So why the heck is it even in there then?Anyway, I was hoping that I could use Mitrolan as an alternative, but I can't FIND it anywhere.
