A Game Changer
About a year ago I was struggling with on and off lameness with my 8-year-old show horse. I wasn't ready to dive into joint injections so I decided to give Summit a try first. Ever since, she has been completely sound and moving better than ever.

I can feel the difference
Summit keeps my mare feeling great. She is 19 and has been on it for 6 years now. I felt a difference the next day. My dog went from limping to running again when he started his Summit. Great products!

Noticeable improvement
Just finished the four-week starter course and it seems to be really making a difference. Joints don't seem to be as creaky and my horse is definitely moving better. I'll be purchasing again.

Game Changer
I started my senior on this and it is a game changer! He moves so much better and I've been able to take him off other joint meds because of this. Highly recommend trying for any horse whose joints need attention.

Arabian Mare Now Walking
I started my 27-year-old mare on the IM on Feb. 2 in the morning. She could barely walk and all four legs were stocked up. By late afternoon she was moving at least 25% better. By the 5th she was walking without hesitation. She has improved at least 50%. I don't know how this is possible.

She's Got Her Sassy Back
