Really, best course of action is not to guess and just get blood work done regularly. It builds up slowly enough that your doc may suggest mega-dosing for a few weeks to bring things back in line. Pure anectdata on the auto-immmune thing: since getting my vitamin D levels up, my alopecia barbae has completely disappeared. It's pretty crazy cause it's something I've had my entire life (and very severe at times). My doc mentioned a link between auto-immune and vitamin D, and after bringing my levels back in line, all the patches filled back in. Pretty wild, tbh.
