Will my horse like the liquid/flavor?

Our experience is that horses do love the flavor of the liquids as the product is specifically designed with dogs in mind. An added benefit is pet owners love the convenience!

If my horse is on anti-inflammatory drugs can I use RJX with them?

Yes-the two treatments can be combined. Since medications have side effects the ultimate goal is to reduce the medications or eliminate them entirely as your horse improves.

Can I give RJX to my or young horse?

Yes. For your young horse follow the instructions on the bottle, the dosage is based on body weight.

I put RJX in the refrigerator and crystals formed. Is this normal and can I still use it?

If crystals form, this will not cause a problem with efficacy, however, you  may need to heat the product or raise the temperature before dosing to get the MSM back into the solution. Usually, setting the solution in warm water for some time works best without overheating the product.
