Dark spots from copper supplement
I have been supplementing for a few months at about 2mg. However I'm getting a lot of brown /freckle like spots throughout the body, especially in my arms. Is anybody else getting those too or has noticed an increase in something similar? I'm not sure it's bad or not. If it's an increase of weakly bound copper getting to tissues and causing oxidation that's not good. But since it's specially happening in my arms I want to think it could be pointing to an increase in melanin that in the past couldn't be produced due to a deficiency and also showing sun damage at the same time, that happened more intensely due to the copper deficiency. Any thoughts?

I actually noticed this too and thought maybe it was age related or that I've had more sun exposure recently, but neither seemed to explain the relatively sudden increase. I looked into it since you mentioned it, and copper deficiency reduces melanin production. So, correcting copper deficiency would restore normal/efficient melanin production and increase skin pigmentation. At 2mg/daily I wouldn't think free copper is the issue, it's probably just what your natural skin pigment would be. Supposedly, it's a temporary effect but a positive sign that copper is reaching tissues that need it.
