Right now the best value across our full Copper catalog is at $0.03 per serving.
Copper is an essential mineral that serves as a cofactor for several enzymes (cuproenzymes) involved in energy production, iron metabolism, neuropeptide activation, connective tissue synthesis, and neurotransmitter synthesis, and it contributes to processes such as angiogenesis, brain development, pigmentation, immune system functioning, and defense against oxidative damage through copper-containing superoxide dismutases. The NIH Office of Dietary Supplements notes that copper might play a role in two conditions studied to date, cardiovascular disease and Alzheimer's disease, but observational studies on copper concentrations and cardiovascular disease have had mixed results, and the evidence to date is insufficient to support conclusions about copper's effect on these conditions. Based on studies in animals and humans, the effects of copper deficiency include anemia, hypopigmentation, hypercholesterolemia, connective tissue disorders, osteoporosis and other bone defects, abnormal lipid metabolism, ataxia, and increased risk of infection. — per the NIH Office of Dietary Supplements; not medical advice.
Copper dietary supplements come in several forms, including cupric oxide, cupric sulfate, copper amino acid chelates, and copper gluconate, and copper is also found in many multivitamin/mineral products. According to the NIH Office of Dietary Supplements, no studies have to date compared the bioavailability of copper from these and other forms. More generally, the sheet states that copper absorption is strongly influenced by the amount of copper in the diet, with bioavailability ranging from 75% of dietary copper when the diet contains only 400 mcg/day to 12% when the diet contains 7.5 mg/day.
The richest dietary copper sources include shellfish, seeds and nuts, organ meats, wheat-bran cereals, whole-grain products, and chocolate. By serving, pan-fried beef liver and cooked eastern oysters are by far the highest, followed by unsweetened baking chocolate, potatoes, shiitake mushrooms, cashews, and crab; tap water and other beverages can also contribute, though the amount varies by source — per the NIH Office of Dietary Supplements.
Copper deficiency is uncommon in humans, but the groups most likely to have inadequate copper status include people with celiac disease (due to intestinal malabsorption), people with Menkes disease, and people taking high doses of zinc supplements, since zinc can interfere with copper absorption. Based on animal and human studies, the effects of copper deficiency include anemia, hypopigmentation, hypercholesterolemia, connective tissue disorders, osteoporosis and other bone defects, abnormal lipid metabolism, ataxia, and increased risk of infection — per the NIH Office of Dietary Supplements.

Yes. The is 10,000 mcg/day for adults 19+ (including pregnancy and lactation), based on levels associated with liver damage. Chronic exposure to high levels of copper can result in liver damage and gastrointestinal symptoms such as abdominal pain, cramps, nausea, diarrhea, and vomiting. — per the NIH Office of Dietary Supplements; general information, not medical advice.

Groups most likely to have inadequate copper status include people with celiac disease (intestinal malabsorption), people with Menkes disease (a rare X-linked disorder of copper homeostasis in which intestinal absorption of dietary copper drops sharply), and people taking high doses of zinc supplements, since high zinc intakes can interfere with copper absorption. — per the NIH Office of Dietary Supplements; general information, not medical advice.

Chronic exposure to high levels of copper can result in liver damage and gastrointestinal symptoms such as abdominal pain, cramps, nausea, diarrhea, and vomiting, though copper toxicity is rare in healthy individuals without a hereditary copper homeostasis defect. The Food and Nutrition Board has set Tolerable Upper Intake Levels (ULs) for copper from food and supplements based on levels associated with liver damage, reaching 10,000 mcg/day for adults age 19 and older (8,000 mcg for ages 14–18) — per the NIH Office of Dietary Supplements.
