I’m not normally one to start adding things to feed and expecting the world to turn upside down, but I LOVE this supplement. My thoroughbred gelding has struggled with sun bleaching and a dull brittle coat his entire life during the summer, and as he’s aged it’s gotten worse through the fall as well. I decided to add the 3:1 zinc/copper to help him grow healthier hair and protect his skin more, and boy it did not disappoint. The first photo is how he started around early July, the next is two months after starting, and the last photo is him now.
