vit. b12 shot
I began with 1 ml a month and next time my labs were done my B12 was in the normal range but not as high normal as I (and my dr) would like it. I changed to once every 10 days and rechecked labs. Now I've settled in at once every 2 weeks and that seems to work well for me. I can't tell a difference in how I feel but since I have my labs done 3 times a year I can go by my numbers.
