Can I bring ZMA tablets on the plane?

Hi, I'm leaving to Santorini from Norway. I work out 7 days a week and I take quite a few supplements. I'm wondering if I'm allowed to take my ZMA pills, protein powder, Creatine powder and L-Glutamine powder with me? I mean they do resemble drugs... But all 4 are of course 100% legal. I just don't want to get stopped and have them taken away from me.
