Any of you that have been diagnosed with B12 deficiency, what were your symptoms? I'm afraid that is what's going on with me. Help!!!

I can't speak from personal experience as my levels hover at the top, or just over the top, of the normal range, but B12 is a component in the making of red blood cells, so a deficiency tends to show up as anemia to one degree or another. It is also a regulating element for homocysteine levels which has cardiovascular implications but no immediately noticeable symptoms. But if you're feeling lethargic, B12 is one of the things to check (along with iron, protein and carb levels.)

I was too diagnised with low b12 and iron... Also low protein... =s.

My nut prescribed me 1 shot of n complex and iron every week for one month.

I left my protein shake... Thatsthe teason why im low on protein... I started again with shakes... I had no symtomps
