Condition
Copper Deficiency
Copper deficiency is a condition in which the body lacks enough copper, a mineral that helps enzymes build connective tissue, make red blood cells and support nerve function. Copper is the supplement with the clearest research here, and the evidence is strong that blood copper levels went up. That finding is about a lab measure, though, and it doesn't tell us how symptoms changed for people with the condition.
