What's the difference between Re-Lyte Hydration and Re-Lyte Pre-Workout?

They both contain electrolytes, but Pre-Workout contains extra ingredients that give you energy and endurance for your workouts.

Re-Lyte Hydration contains a finely tuned dose of the electrolytes sodium, chloride, magnesium, calcium, and potassium to keep you perfectly hydrated. Re-Lyte Pre-Workout contains all of these beneficial electrolytes too, plus it includes green tea extract (which contains caffeine), beta-alanine, vegan BCAA's, taurine, ginseng root, and maca root to give you the energy and endurance you need to tackle your workouts.
