I don't have an answer for you but I have normal
ceruloplasmin. I am 46 with hardly any grey. I have kinda been wondering why I didn't have more grey in my hair. When I started detoxing I noticed more grey hairs. I don't know if that is related to just depleting needed minerals or the copper.
I didn't really notice a copper dump until I was way into the Zinc but keep in mind I was also taking MSM. Now I am just doing just the Zinc not the MSM. Are you taking any selenium? I didn't and should be to help detox the mercury.
