Kate,

B-12 is a serious part of my daily regimen. I take about 400 micrograms daily. 1000 micrograms sounds high unless you have had blood work done to show a deficiency. It is thought that B-12 can be overdosed. It has been suggested that high doses can cause excessive cell regeneration to the point of cancer.

There are two forms of B-12. One is oral and the other is injected. Some people do not uptake the oral B-12 sufficiently so they need the shots.

I was given B-12 injections once a week for 8 weeks back in 1983 for a serious decompensation. It helped greatly.

On Wednesday, I get my labs read by my new physician. He has had me tested for B-12 along with hormones and such.. I am interested in what he finds as I take 380 mcgs of B-12 daily.
