Your B12 is low esp.for UAT. It's easy to get the Methyl [better utilised] B12 version on line -and dose under tongue.

In Japan the lower limit for seniors is 500. So age is a factor as well.

If you're a Veggy ,like me, this could lead to low B12, as animal sourced - but someone else will have to comment on your Iron result.


Thanks tegz- I will certainly look into that.x


Please read my blog on B12 here:

Your level is low enough to be of concern. If you are symptomatic, use the article (above) to discuss with your doctor. Symptom list:


If you're not sure, consider the Active B12 test:


Thanks hampster1.Have read all your info.VERY useful!Have many symptoms of PA -my mother has had PA and UAT for years.But when your GP reassures you that your blood test results are absolutely fine.......... : (


.....I keep saying to myself, now remember, GP's have only had about half a days training on nutritional deficiencies, and they might have been off sick that day as well (maybe with some unexplained fatigue)? But I still find it almost impossible to excuse the level of ignorance out there by some - not all - but probably, sadly, the majority.
