I took a lot of cod liver oil once it started, maybe a little bit before too, so I suppose it could be that. I did a lot of research into what would increase NAD levels, and it’s all pretty inconclusive, so I figured niacinamide was as good as any other B3 in the pathway. I later found that it chelates with some minerals, so I may be giving myself a deficiency.

Yes a deficiency is far more likely than an autoimmune disorder
