Methylcobalamine source in Europe?

I am looking for clean options for giving my cat Mathylcobalamin. We are in Spain.
I cant get Zobaline so another one will have to do the trick. Can anyone recommend some nice brands or what are they using? Thank you!

 

They don't sell vitamin supplements in a pharmacy there?

 

They do but they have all sort of stuff added so I want aome clean one, just the methylcobalamin and one-two excipients tops. Plus, they come 1 mg per pill and I already pill him so much, 3-5 capsules a day more would be so difficult for him.
Maybe they could be opened and added to food but not sure if they taste ok and he will eat.
