Hello I was ordering bififlor forte on the internet and it takes a few days to ship to Iceland. Is this something that need to be kept in refrigdirator. Will it be okey when I will receive it. And if not can I just buy some probiotics. Another thing I got prescribtions for b12 10 mg 2x a week and we just got 1mg here in my country. Also I have been on methylation cycle for to years and my b vitamin is 740 wich is too high. I really dont think I need this much b12. What is it supposed to do. I have high b12 now and always tired so I dont see the point taking so much. Please comment on this and tell me if I am wrong.
