    Hi your folate and ferritin have to be at a good level for b12 to work, your gp should check both also other tests to see if your absorbing B12

      folate 4.1 bottom range is 3.8, ferritin is 22, low range 11, got iron pills for that but had to argue to get them, now told may be carpel tunnel syndrome in wrist, but i dont think so as have same sort of deep ache in ankles and in shins on and off, my legs feel heavy and ache, sleep in afternoon, headaches, tinnitus, slightly forgetfull, blurry red eyes on and off, tingles in arms and some in my bak too, drs say no to b12, not the right symptoms and blood is okay, even when i pointed out mch, mcv would be made normal by the low ferritin levels, thanks x

    Any digestive problems can have an effect on your ability to absorb B12 from your food. Depending where you live they will treat anything under 200 as deficient. Some countries treat under 500. So you could well have symptoms at 300 or thereabouts. Only a percentage of the B12 detected in your blood is going to be used by your body. Are you taking any supplements at all? Have a look at the Pernicious Anaemia Society website for more information and a full symptom checklist. Best wishes Marion
