Copper aids in the absorption and utilisation of iron, for blood cell production and is necessary for several enzymes involved in vital processes, as well as regulating the normal pigmentation of hair. How does it work? Horses are very tolerant of copper but over supplementation can interfere with the absorption of Zinc and Iron.  A lack of Copper can show as anaemia, poor growth, hair de-pigmentation, weight loss and some bone disorders.  Copper Plus supplies a high quality dietary copper along with supporting vitamins and minerals for absorption and utilization.
