I have Hashimotos which is doing very well with meds and low carb. My Vit D however is another story. It was at 7 and we brought it up to 13 but couldnt increase it further. I have tried meds, sunshine (was already doing anyway) and milk. I have now stopped drinking milk (lactose issues my entire life) and after reading studies stopped the weekly Vit D supplement. It didnt matter anyway since neither of which were working. I was doing them for over a yr so time wasn't the issue.
