Your horse’s health is important, and hydration is key—but horses need a trigger to drink! They’re fussy when it comes to being introduced to strange water, which creates particular challenges on the road. Rein Water is an all-natural powder additive that includes a blend of essential trace minerals, clay and electrolytes your horse needs to stay hydrated and healthy. Rein Water masks the alkaline taste of treated water, and horses love the flavor—which encourages them to drink more.
