[Currently taking: 50-mcg Synthroid / 15-mcg Liothyronine]
My doctor's office called and said my levels were fine, but why would my B12 level be high if I am not taking B12 supplements? And shouldn't I have a higher level of Vitamin D?
Vitamin B12 (211-946 pg/mL) 1053
Folate (>3.0 ng/mL) 14.3
Vitamin D (30-100.0 ng/mL) 36.8
