Vitamin B12 Deficiency - Why in the deficiency of vit b 12 the size of rbc increased?

Roughly, Vitamin B12 helps produce red blood cells. With lower amounts of B12 the RBCs that are being produced are forced to carry more oxygen (your body still needs the same amount of oxygen), so in order to do this the RBCs have to carry more oxygen which leads to the increase in size. This is a problem because they're not meant to be that large.

I think its not a real answer

That was one suggestion on the issue. Another one that pops up from another legitimate source says that vitamin b12 helps divide the rbcs at one point. This means with a lack of vit b12 the cells cannot divide. Do as you wish with both answers from legitimate sources.

My husband had a b12 deficiency and went for shots until it got up, now he has to take 1000mg a day.

Not sure if your husband is aware about it yet but I recently heard about a new alternative to the injections. Has anyone heard of it, it's called Eligen B12? Apparently it is the first and only true alternative to the intramuscular injection. I recently read that it works as well as the IM injection even if you don't have intrinsic factor (so even if you don't have normal gut absorption). It’s a once daily pill that apparently it came out a month or two ago. Might be beneficial to him!
