The Health Factory Nano Zinc/Copper is perfectly balanced Zinc and Copper to allow you to rebalance the zinc and copper levels in your body. Zinc and Copper go to the same cell receptors and so its vitally important that you have the correct balance. You need 10:1 Zinc to Copper ratio for a proper equilibrium to be maintained in the body. We would recommend using Zinc and Copper when you need to raise your zinc levels unless you’re aware of problems with supplementing Copper. Because the particles are so small and perfectly spherical, they are able to pass through the soft tissue in your mouth and through the mucus membranes of the digestive system to pass directly into the blood. Essentially, this product does not need to be broken down by the body and completely bypasses the digestive system. Zinc is vital for many aspects of our health, including supporting reproductive health and our immune system.
