Vitamin B12 Blood Test Accuracy
(los angeles ca)
I had a B12 shot a while ago and felt terrific for a day or 2. I am 63 - bad memory very tired all the time and some of the other symptoms I believe my doctor tested for a deficiency and said I didn't. I don't eat meat with the exception of chicken and some fish. Could it be I can still have it without it showing up on a blood test?
Many thanks for your help with this.
PS Would patches work as well as the shots. I'd sure rather have a patch then a shot and esp since the shots don't last.
