5. Boosts immune system
Copper is responsible for the activation of certain enzymes that have a significant role in immune cell proliferation and maturation and help fight bacteria, viruses, and other foreign bodies.
It is also directly responsible for the production and proliferation of neutrophils, white blood cells and the first line of defence in white blood cells. Studies show that copper deficiency is combined with a reduction of interleukin, responsible for T white blood cell proliferation.
