I had my B12 tested in April and it was 484. I decided to take B12 supplements after reading B12 should be a minimum of 700. I've taken the supplements for nearly 3 months and had a blood test again (while on supplements, I think it's more accurate if I'm off the supplements for a month before having a blood test) and its now 1374! A big jump. Is this too high or ok?
FYI I have been diagnosed with hypothyroidism and am taking T3 only.
