Hi,
I’ve recently had a blood test for thyroid issues and the results have come back showing elevated levels of active vitamin b12 (269pmol/L). I’ve never taken any supplements for b12 and don’t drink energy drinks. I’m unsure wether this is significantly elevated or just slightly as I haven’t seen my gp yet since receiving the results. I’ve been quite worried as when researching all I can’t find are cancers, liver and kidney problems. If anyone could help I’d really appreciate it. Thanks.
