In a study of 200 adults and children with celiac disease, of which 69.9% claimed to maintain a gluten-free diet, 15% had copper deficiency (less than 70 mcg/dL in serum in men and girls younger than 12 years and less than 80 mcg/dL in women older than 12 years and/or CP less than 170 mg/L) as a result of intestinal malabsorption resulting from the intestinal lining alterations associated with celiac disease . In: Ross AC, Caballero B, Cousins RJ, Tucker KL, Ziegler TR, eds. Menkes disease is a rare, X-linked, recessive disorder of copper homeostasis caused by ATP7A mutations, which encode a copper-transporting ATPase . Dietary Reference Intakes for Vitamin A, Vitamin K, Arsenic, Boron, Chromium, Copper, Iodine, Iron, Manganese, Molybdenum, Nickel, Silicon, Vanadium, and Zinc. The amount of copper in dietary supplements typically ranges from a few micrograms to 15 mg (about 17 times the DV for copper) . Proc Nutr Soc 2011;70:1-9. Copper is a mineral by definition because it is a native element on Earth. People with Celiac Disease Most of the worldâs copper comes from the minerals chalcopyrite and chalcocite. Important Examples of Deposit Type No basaltic copper or Kennecott-type mineral occurrences are known in southwest Alaska. However, plasma CP and copper levels can be influenced by other factors, such as estrogen status, pregnancy, infection, inflammation, and some cancers . Tolerable Upper Intake Level (UL): Maximum daily intake unlikely to cause adverse health effects. Chronic exposure to high levels of copper can result in liver damage and gastrointestinal symptoms (e.g., abdominal pain, cramps, nausea, diarrhea, and vomiting) [10,40]. Almost two-thirds of the body’s copper is located in the skeleton and muscle [1,3]. Longitudinal analysis of serum copper and ceruloplasmin in Alzheimer's disease. Chrysocolla and malachite also are mined for copper. Copper deficiency is uncommon in humans . Association Between Serum Ceruloplasmin Specific Activity and Risk of Alzheimer's Disease. In an earlier meta-analysis of 26 studies in a total of 1,058 patients with Alzheimer’s disease and 932 controls, those with Alzheimer’s disease had significantly higher levels of serum copper than the healthy controls . It is also soluble in aqueous ammonia or potassium cyanide in the presence of oxygen because of the formation of very stable cyano complexes upon dissolution. Copper is usually found in nature in association with sulfur. Copper is not known to have any clinically relevant interactions with medications.

One abundant cuproenzyme is ceruloplasmin (CP), which plays a role in iron metabolism and carries more than 95% of the total copper in healthy human plasma . A randomized trial of copper supplementation effects on blood copper enzyme activities and parameters related to cardiovascular health. Furthermore, copper accumulation in damaged brain regions in Alzheimer’s disease might not directly reflect overall body copper status or copper intakes . Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper â¦ Alzheimer's disease as copper deficiency. Human studies typically measure copper and cuproenzyme activity in plasma and blood cells because individuals with known copper deficiency often have low blood levels of copper and CP . 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 .
