Equilytes® was originally formulated for race horses for rapid electrolyte replacement, so our patented blend absorbs immediately. All other brands take over eight hours to be absorbed by the gut. This also allows electrolyte absorption even during the athletic event, giving you that competitive edge when you need it! Studies have shown the use of Equilytes® effectively delays fatigue and prevents symptoms of muscle cramps. In a similar manner, a dose of Equilytes® before loading into trucks or trailers greatly assists the horse’s condition upon arrival at his event.
