Rated 5 out of 5 by from Palatable and effective My mare has been on this for several months now, and I really think it has made a difference. More so than mare magic.

Rated 1 out of 5 by from Moody Mare Was having some issues with my mare so I decided to try Mare Harmony per recommendation. After a while of using, I saw no difference or change. Switched to SmartCalm Pellets and started seeing results within a week.

Rated 5 out of 5 by from Absolute Miracle!!! It’s only been a week… It has only been a week and I have never had a more relaxed and happy mare. My mare was never mare-ish, but super anxious and hot. I decided on a whim to supplement her hormones and within 2 days I had a different horse. I can now jump and gallop her in a halter without playing tug of war. She is soft, quiet and responsive. I am so happy I put her on this!

Rated 5 out of 5 by from Only thing that made a difference My 20-year-old mare had a serious attitude issue out of the blue last year. She was always the last girl in the pecking order and suddenly became very aggressive toward the other horses, even the bully of the bunch, and after she bit my landlord's horse I had to do something. We tried shots and other supplements but nothing made a significant difference. My vet finally said I should try this. After a couple of weeks I started noticing a difference (this was late spring) and then all summer she was great. It even helped her feel better when I was riding her (back pain). She took it all the way into the fall and over the winter until she was moved to a warmer pace for the coldest months. Starting her back up again now. I get it shipped automatically so I don't run out. I highly recommend this supplement and have recommended to many others as well

Rated 1 out of 5 by from No results Going on 4 months. No difference in marish attitude

Rated 5 out of 5 by from Worked great I put 2 of my horses on Harmony supplements and the pasture is calm and quiet again. It does the job of mellowing the aggressive tendency in both. One is a mare and the other a gelding and it is working on both.

Rated 5 out of 5 by from Mare Ease My mare had such cramps and issues that several years ago she ended up in tufts for 10 days. Tried numerous supplements to stop the problem and Mare Ease is the ONLY thing that has worked. She has been on it for many years and has never again had a problem. If you own a mare you need to be using Mare Ease!!
