I posted recently about flu and changes in my thyroid medication - currently on 100mg Levo and waiting to test in early August. I forgot to mention my vitamin levels which I think look low. Thoughts?
Vit B12 452 ng/L [>140ng/L] tested 21 June - concerned that this is suboptimal. Taking B complex with 10mg B12. About to start 1000mg sublingual methylcobalamin as well.
Vit D 44.8 nmol/L [>50.00nmol/L] tested 9 May
Folate 11.9 ug/L [>4.00ug/L] tested 21 June
Serum ferritin 71 ug/L (24-250) tested 11 April
