How long until you started to feel better after starting b12 injections? I had my first one today. I will be doing them once a week for the next 3 weeks and then going to once a month if my levels have improved. I am on the very low end of the healthy range, almost out of it. Thanks!

    My doctor told me it takes a while to actually start to be effective. You don't really notice a change until at least week 5 and theres really no marked improvement until 3 months. I understand the frustration. Please hang in there. It just take a little time for your body to adapt. Hopefully this gives you the relief you need

    It will take a few months to fully work. I have been on b12 injections once a month for several years & they help me quite a bit
