Quoting TooManyWordsToKnow:" Ok thanks so much! I was totally misunderstanding the descriptions for it . I thought it was for weightloss ... [snip!] ... strictly. So, for after a strength workout does it help e ase soreness? Would it be safe to take with a multivitamin?"
It does help ease soreness after a work out because it helps rebuild the muscle you just broke down.
And it is safe to take with anything really, just think of it as eating a steak but without the fat. It's just protein and nutrients really
