Read about the effects of Copper in relation to the amount of evidence we've found
Does copper improve or impair cognitive functioning?
Copper has been found to be increased in people with Alzheimer's compared with healthy controls [1].
However, in one study copper intake had no effect on cognition in patients with Alzheimer's disease [2].
Increased copper intake may lead to neurotoxicity through an increase in the production of reactive oxygen species [3].
Copper may or may not contribute to cognitive decline. Anyhow, it is likely not an effective cognitive enhancer.
Does copper improve or impair mood?
In one study, mega-doses (1g/day) of copper improved mood status compared with placebo in pregnant women [4].
However, that is the only study that has examined the effects of such high doses in humans, and the only study which has found positive effects. One gram of copper daily may be dangerous, but it was reportedly safe in this study.
In other studies, increased blood levels of copper were found to be associated with increased risk for worse mood [5][6][7][8].
Copper supplementation is likely not a good strategy to improve your mood.
