Didnt you say your zinc was showing low as well? You should be getting blood tests to make sure these are both improving.
my zinc and copper were always low and didn’t go up even with high zinc / copper foods or supplements.
after months they went very slightly up.
i hope this changes when taking higher doses.
I meant checking copper every few months (zinc of course too) to make sure I don’t get issues with absolutely not absorbing any copper anymore from high zinc doses.
