I did the weekly programme in the set time with no major issues, starting in Jan 17 and was getting B12 injections every 6 weeks at the time as I had done for the previous year but the last two months have been a major struggle and I think the running must be depleting my B12 faster than I'm getting it injected, hence I had to pay for an injection privately after only 3 weeks and take a full week off running.
Been out this weekend post injection and a week's rest and found it fine again. I don't want to stop running, I'd rather pay for more injections (if I can't get them off my dr) but this has really thrown me just how depleted I am getting so quickly.
So does anyone run with B12 and how have you found it compared to pre-exercise? how much more rest or more regular injections compared to pre-running? any other solutions?
I'm only running 3 times a week at quite a slow pace for about 30 mins, this is nothing compared to the level of exercise I did pre deficiency issues so I don't feel I'm over doing it compared to what a normal person should be able to do easily.
