During the summer months, horses lose essential minerals—known as electrolytes—through increased sweating. These electrolytes are vital for the healthy functioning of their bodies. Sweating not only serves to cool the body but also results in significant salt and water loss. If these losses are not replenished, it can lead to decreased performance, muscle cramps, circulatory issues, or, in more severe cases, heat collapse.
What Many Riders Don’t Know: Horse Sweat is Hypertonic
Horse sweat is hypertonic, meaning it contains a higher salt concentration than the horse’s blood. This means that when a horse sweats a lot, it loses not only water but also disproportionately large amounts of sodium, potassium, chloride, and magnesium.
(Schott, H.C., "Sweating and electrolyte loss in horses," Veterinary Clinics of North America: Equine Practice, 2011)
➡️ Surprising fact: A horse can lose as much as 60-100 grams of sodium during a single intense workout in hot weather. This is roughly equivalent to 150–250 grams of salt!
Water Alone is Not Enough
Many people believe that simply providing fresh water is sufficient. However, this does not replace lost electrolytes. Drinking plain water after electrolyte loss further dilutes the blood plasma, which can lead to a worse condition—known as hyponatremia (low sodium levels).
Electrolyte Replacement: Not Just for Racehorses!
Electrolyte replacement is necessary not only for sport or racehorses. Hobby horses, trail horses, and even stabled horses lose large amounts of electrolytes during hot summer months, especially if they:
- regularly work or exercise,
- or stay in enclosed spaces with high temperatures.
Introducing Re-Hydra – Electrolyte and Recovery Supplement for Horses
Re-Hydra is an advanced, multifunctional electrolyte supplement that not only replenishes lost minerals but also supports muscle recovery and cellular hydration balance.
Composition:
- Potassium chloride (K): 26%
- Sodium chloride (NaCl): 37.9%
- Chloride (Cl): 53.5%
- Trisodium citrate & sodium bicarbonate: help maintain blood pH balance
- Trimagnesium citrate: supports muscle function
- Vitamin C: antioxidant, cell protection
- MSM: anti-inflammatory, tissue regeneration
- Glucose: enhances intestinal electrolyte absorption
- Glucosamine: joint protector, long-term support
Why Choose Re-Hydra?
✅ Ideal electrolyte ratios: Sodium, potassium, and chloride are balanced according to the latest research, optimizing fluid retention and restoring blood electrolyte balance.
✅ Citrate-form salts: Gentle on the stomach and quickly absorbed—especially important after racing or intense work.
✅ Extra functional ingredients: MSM, glucose, vitamin C, and glucosamine mean Re-Hydra not only hydrates but also protects, regenerates, and supports overall health.
Summary
During the summer months, electrolyte replacement is not a luxury but a necessity for maintaining your horse’s health and performance. Re-Hydra’s scientifically based formula provides comprehensive, targeted support that goes far beyond a simple salt mix.
🔹 Give your horse Re-Hydra daily in hot weather, or after intense work, travel, or competition—and notice the difference!
