Yes, maybe I should double it. I hope eating small amounts of liver regularly with coffee to inhibit iron absorption helps with raising ceruloplasmin, I am weary of supplementing minerals individually, also my serum copper is not that low so I actually have issues with ceruloplasmin. Have you ever heard of molybdenum raising ceruloplasmin?After I supplemented high vitamin D or havent taken magnesium for a long while I can easily take 1 gram across the day without getting runny stools so I think thats a good sign if you are low. Imo you can double the A and D. Dunno about zinc. I can not tolerate any zinc. Are you donating blood aswell? If so you take B vitamins? It will help with hemoglobin synthesis. Like ray also says donating blood depletes other nutrients probably like copper. I took between 2-10mg copper daily for 2 months to get my ceruloplasmin from 150 to 200. Below 150 is really low. 300 is not high. Many test has upper range of 600.
