Hi Everyone,
I would just like some advice on taking B12 complex please. Just wondering if this is usually necessary long term if someone is self injecting B12 which I am. At the moment I am taking Swansons B12 which does have Biotin in it. I am wondering if Biotin is needed. i mainly started taking it as it has folate in it and my levels were low last time they were tested. I would just like to know if I need to keep supplementing when SI please? Thank you.
