What does copper do exactly?
Copper is important for getting iron into haemoglobin (the protein that lends blood its red colour). Haemoglobin ensures that oxygen can be transported from the lungs to the organs and tissues. Conversely, it also ensures that carbon dioxide can be transported from the organs and tissues to the lungs. In addition, copper helps with the formation of bones and connective tissue and with the formation of pigment in hair and skin. It will also ensure that your four-legged friend has a good immune system.https://www.yarrah.com/uk/faqs/ingredients/what-does-copper-do-exactly/
