I actually started using this product to help treat a different issue entirely, and it turned out to completely change my horses quality of life! I have a cowbred quarter horse that when he was 18 years old, he started showing signs of coronary band dystrophy. After 6 vets and every oral/topical medication under the sun, nothing seemed to treat it. Flash forward to two years later of just managing this issue, he had an unrelated eye injury occur. The vet recommended that we put him on the equishield to help boost his immune system. After two weeks of being on the supplement his coronet bands completely cleared up (his eye cleared completely up, not from the supplement but that’s a story for another day). As long as he stays on this supplement he is 100%. He is going on two years on this supplement hasn’t had an issue with his bands since. Thankful for this product!
