Digestive Supplements for Horses
Equine Gut Health - What's the big deal?
Equestrians see problems like anxious behaviour, girthiness, laminitis, weight challenges so often that they are often seen as ‘normal’. But are they really? What’s causing your horse to not feel their best? Leading scientific research is showing that poor gut health in horses can play a major role in causing of all of these issues.





Support your horse's performance
From a mineral and vitamin balance with the right fibre and forage, to great gut health, a horse enjoying a healthy digestive system and good nutrition is able to perform at their best.

I can’t get low sugar hay for my horse - now what?
Help - my horse is Grass Affected!
The term grass affected is often used by horse owners and equine professionals - but is “grass affected” based in science, or just a catch-all to explain our horse’s behaviour? The truth is, it’s a bit of both. Here's specific list based on science and expert knowledge of what is in grass that can affect our horses.
