I have an under active thyroid and I recently had my B12, Ferritin and Folate tested and was hoping I could get some advice. The results were:
B12 - 308 ng/L (211-911)
Folate - 10.1 ng/ml (5.4 - 24)
Ferritin 163 mg/ml (10-322)
I know my B12 is low but as its in range and the IF antibodies came back normal the doc wont do anything. Does anyone have a recommendation of how much B12 to supplement to improve these levels? I have read sublingual is better and 1000mcg a day?
It would be good to have an opinion on the Ferritin and Folate as I have no idea if these are optimal at all?
I also just has a question about what vitamins and minerals people take daily and on what dose? I have done quite a bit of reading but I am finding all the info quite overwhelming. I currently take D3 1000UI a day as I had my D levels tested a while back and they were low but normal range.
Thanks very much
