I was diagnosed with B12 deficient Anemia in the 1960's. I took Vitamin B12 shots approx. 20 yrs. (In my case), Now 35 yrs later I am fine. Vitamin B12 did wonders for me. Remember, every persons case is different. I don't know what treatment is today for B12 efficiency. Good Luck to you & your wife. Bea
