As the weather heats up and training ramps up, keeping horses hydrated becomes a top priority especially for performance horses or those working in the heat. One product I’ve come to rely on during warm months is SmartEquine SmartLytes, a well-balanced electrolyte supplement designed to support hydration and recovery.
In this post, I’ll share my honest experience using SmartLytes, what makes it different from other electrolyte options, and how I use it as part of my horse care routine during hot weather.

Why Electrolytes Matter
When horses sweat, they don’t just lose water they also lose vital minerals like sodium, potassium, and chloride, which help regulate hydration, muscle function, and nerve activity. If these aren’t replaced, horses can become dehydrated, sluggish, or even colic-prone. That’s where electrolyte supplements like SmartLytes come in.
What Is SmartLytes?
SmartEquine SmartLytes is a daily powdered electrolyte you can top-dress on feed or mix into a water bucket. It’s formulated to replenish key minerals lost through sweat and encourage horses to drink more water, especially in hot or humid conditions.
Why I Use It
I live in a region where summer heat can creep into the 90s (and beyond), and my horses are still working and traveling during these months. I use SmartLytes as a preventative tool to:
- Support hydration before, during, and after exercise
- Keep electrolyte levels balanced during heat waves or stressful events
- Encourage more water intake, especially after hauling
My Experience (The Honest Take)
What I like:
It works. I notice my horses drink more consistently when I use this supplement —especially after hauling or working in the heat. Their energy stays up, and I’ve had fewer concerns about sluggish recovery or dehydration.
It’s palatable. Even my pickier eaters don’t seem to mind it on top of their feed. I haven’t had issues with horses refusing it (which I have had with other brands).
No unnecessary fillers. The ingredient list is straightforward, and it doesn’t include excess sugar, which I try to avoid in supplements.
Good value. Compared to some name-brand electrolyte pastes or powders, SmartLytes is reasonably priced and lasts a while.
Things to note:
️ It’s a powder, not a paste so it works best as a daily supplement, not a quick “emergency” fix after a big sweat. For that, I keep paste electrolytes on hand.
️ Not all horses love it in water, so I usually mix it with grain to be sure they get the full dose.
