Does anyone know?
For example: ON Casein has both whereas Labrada's PROV 60 only has Calcium Caseinate?
Micellar is like... um, more expensive, and... better?
I've read this shit sometime, I think it's shit about bioavailability. Micellar isn't as harsh on your bowls either from what I recollect, ie you won't be shitsquirting and farting bombs.
