I have a 9 year old appendix mare I got last year. The only thing we changed when we got her was putting her on Animal elements Detox and NuTrack. She looks so much better. Her coat shines and she has mellowed out. She does not try to bite me anymore when I cinch her up and is overall a ton happier. I use these products on all my horses and I love how my horses look and act on them.
