Experts participating in the 2013 International Conference on Nutrition and the Brain suggested that individuals at increased risk of Alzheimer’s disease using multivitamin-mineral supplements choose those that have no copper (or iron) because excessive intakes of these minerals could contribute to cognitive issues in some patients [39]. London and New York: Informa Healthcare; 2010:604-11. Overall, the evidence to date is insufficient to support any conclusions about the association between copper concentrations and CVD risk or the impact of copper supplementation on CVD. In a meta-analysis of 10 studies in 867 healthy individuals and 599 with Alzheimer’s disease (mean age greater than 70 years in both groups), patients with Alzheimer’s disease had significantly higher serum levels of copper not bound to CP and total serum copper than healthy controls [36]. The rock or mineral that holds the metal is called an ore. An ore is heated with chemicals until it melts and the pure metal separates out as a liquid. Copper, an essential mineral, is naturally present in some foods and is available as a dietary supplement. Copper sulfide ores are typically the most profitable copper ore type to mine.
