A friend recomended Simple System for my fizzy 5yr old Arab mare who was becoming a pain, bolted for home on a hack, always hungry and would nip but was worried to feed to much in case matters got worse. I bought Lucie Nuts, GreenGold and Lunar Eclipse, with the view that I would make decision when I had used it all. After only 10 days I knew I would never feed my horse anything else. She is now affectionate, calm and an absolute pleasure to ride, but still with the energy to perform.
