How much B12 supplements?

[mand82]

Just brought some b12 supplements today as my b12 levels go up & way down low yet still feel tired, aching & generally feel like crap ever since I went to the gp last year & had 5 b12 shots , I was just wondering if anyone knows what is the best daily dose? I have got a 500UG bottle of b12 , my b12 levels tend to jump from 117-440, I just wanna feel more awake, less achy, less crappy etc hate feeling like this I can’t concentrate on things & just don’t have the energy etc to do things I want to do

are these levels whilst you are on injections? if so then you probably need the injections more frequently.

I'm afraid people vary so much in how they respond to B12 that it really isn't possible to give a specific answer - all you can do is try - B12 isn't toxic so you son't have to worry about overdosing.

I just checked & I was 117 before the injections in Feb 2017 then after the loading injections I went to 638 June 17 then went down to 428 in December 17 then my last test in March was 411 ,

I’ve decided to take 1000UG daily & will see how that goes then
