They also claim copper supplements don’t raise copper and ceruloplasmin I think.

something like this can’t be so hard to find out I guess? Why is everything so conflicting

The conventional wisdom is that copper supplements are a copper2 form that doesn't get taken up by the cells properly, and then gets stored, attributing to copper toxicity. Copper 1 found in plant sources is supposed to be the form that is used and accepted into the cells for the ETC, etc.
Where is the data showing vitamin A supplements deplete A? There are many out there that ridicule the forms of retinol in supplements, but all you have to do is go to the thread against vitamin A supplements to make your head spin.

Is this really the conventional wisdom?
So copper from chlorophyll with copper complex would be a good source ...

I have no idea what to believe to be honest.
I was reading in this forum people got their copper and ceruloplasmin up with copper supplements too

Perhaps that was a misnomer, however, it is conventional only to people that have subscribed to the idea that the different copper forms function differently in the body, as well as things like oral vitamin D and retinol levels affecting the ceruloplasmin levels and the regulation or dysregulation of copper.
When these 'experts' make claims about vitamin A supplements causing depletion of vitamin A, it smacks of the 'anti-vitamin' propaganda that a lot of these purists spew out, and often times have no science to back their claims up (or clinical or anecdotal evidence). I'll believe it when I see the science. Some of these same people think omega-3 oils are good to consume, just because it came from nature.
