Is there a way to increase metallothionein's in your system, out of curiousity? I'd recently read about its role in PMC6628855 a little while ago and am wondering if there's a way to kind of boost production. Do ionophores cause induction of said metallothionein's? Are metallothionein's the only of its kind or are there any other like substance in our system capable of reducing the T O X l C l T Y of certainmetaIs? Are they specific to zinc and copper? Many questions.
