Is it possible to use Structum, Digavar and vitamins D and C at the same time?

Hello if you can take Digavar and Structure 500 at the same time. I am prescribed both drugs for 3msc 2x a day. I wonder if you can together 2tablets or you should wait (knee injury) The second question is whether, for example, vitamin C, D can also be at the same time lycan as one dose with these drugs or better to wait an hour. Thank you
