Does anyone have experience with having low blood copper and ceruloplasmin levels? Or know of what causes this? Wondering if it is something like malabsorption, Wilson's disease, a result of SOD2 mutation, etc. *I have been supplementing zinc, copper, cod liver oil, vit. C (which supposedly increase ceruloplasmin), but last labs revealed that zinc, copper, and ceruloplasmin levels have decreased further... what to make of this? Thanks!
