Doctor, doctor, give me some news?

I went to the endocrinologist's office today to review my latest blood test (TSH) results for my thyroid. The T3 is down from 8 to (I think it was) 1.9, which she said is very good. She said the T4 was within the norm but was on the edge so we'll see what it looks like in a few months and I'll continue on the medication as is. It's too soon to retest the Vitamin D. She mentioned that I should consider a B complex with some other stuff that I forgot already but I didn't really understand why. So my next ultrasound and blood work will be in January.
