Hi. I hope you all had a happy Christmas and wishing everybody a very happy and healthy (healthier!) New Year.
I requested blood a test following an increase in Levo from 50mcg to 75mcg. My request was not received very kindly from my GP especially when I also asked for vitamin testing. Anyway I got the tests done and results came just before Christmas. I had started taking low doses of supplements before test so stopped taking them about 4-5 days prior to testing. I take my Levo at night so I missed the night before the early morning test. He also refused full thyroid testing saying only TSH is important following original diagnosis.
TSH 0.37 mu/L (0.27 - 4.20)
Serum Vit D 47 nmol/L
Serum vit B12 461 ng/L (197 - 771)
Serum folate 11.1 ug/L (3.9 - 26.8)
Serum ferritin 81 ug/L (13 - 148)
I'm not sure what these results mean so would welcome any advice or thoughts.
I'm not good with iron supplements and never have been. They make me feel nauseous and I get the taste repeating on me all day and I get very constipated.
Prior to testing I took Vit D3 25, B12 100 and absorbable Selenium 200.
Should I continue with these supplements and what dosage? and, when taking supplements can you overdose if taking them continually? should you take a break from them? If so, how often and for how long?
Sorry, such a lot of questions but I really value the advice on this forum much more than I get from my GP. Thank you in advance.
