>>16718972 (OP)Most overlooked condition in the west is probably Vitamin D deficiency. I just had it big time, it sucked ass - My bones hurt, I was tired, depressed, got migraines 3-4 times a week so bad I couldnt do shit.
When I got diagnozed I started taking 100mcg daily for months until I could just get into the sun more, now I feel much better.
Fun fact, did you know they mass produce D3 from washing sheep and processing the wash water?
