My horse is a picky eater, will they like the taste?

Relyne GI is unflavored, so most horses do not have any aversion to it on their feed. It can also be administered via oral syringe.

Is Relyne GI available for purchase outside the USA?

Yes, it is currently available in the UK and Europe. Relyne GI will soon be available for purchase in Canada.

Can I top dress feed that is set up the night before?

Relyne GI can be pre-mixed into the food prior to feeding, but it’s most effective if it's given while the product is still hydrated before it’s had a chance to dry out.

Will Relyne GI interfere with the absorption of any other products my horse is on?

No, Relyne GI will not interfere with the absorption of any of the other products your horse is on. It is completely safe to use with any and all supplements/medications/feeds your horse is on.

Relyne GI does not alter gastric pH like PPIs and H2 blockers, and therefore does not interfere with digestion and/or nutrient absorption. Relyne GI aids in promoting gastric well-being in horses that may not respond to traditional therapies, as well as in equine athletes in training, travel and competition. Relyne GI has been thoroughly tested for banned substances, and is Clean Sport certified.

It works!

Started using this on my vet’s recommendation for hind gut ulcers (tested positive). Three months later we tested again - no hind gut ulcers! It works. Additional benefits included a shinier coat and, seemingly, better joints. He has not needed injections since we put him on it. I have two others horses on it now. One is being shown so for prevention. The other came from the North Carolina sand hills with chronic sand in the gut and has been improving between removal from the sandy pasture and the Relyne GI. He has dapples now.

RyLene product review

I was told about RyLene by a friend. It is a critical part of keeping my performance horse digestive system happy. Which results in his overall performance being better.
