I use this for all my horses along with a selection of red mills horse feed & my elderly horses think they are all youngsters ! I should maybe use it for myself 😊

Great product, horse does not object to it being in her feed which is a huge plus.

Peace of mind

I use this on my hard working and older hunters. It gives me peace of mind that I am doing the best I can to keep their joints in prime condition for the hard work they do

Excellent - has transformed my horse’s performance

Excellent - has transformed my horse’s performance, obvious improvement in suppleness by the end of the first bottle. Very palatable too.

Rhonda CM
Looks promising

Have been using on three horses for over a month. It has all the right ingredients for joint maintenance and very importantly it is palatable. I buy the 5 litre containers and one full pump delivers the right dose straight into the feed bucket so no mess or faffing about with measuring scoops. I bought 3 at once and the price was reasonable. Was given a complimentary Red Mills hat, it's very nice. Happy with my purchase.
