WHY IT'S KETO-FRIENDLY

  • Zero net carbs helps maintain ketosis during training
  • Electrolytes (sodium, potassium, magnesium) support fluid balance
  • No sugar means minimal insulin impact
  • Useful for long or high-heat workouts where sweat losses rise
  • Can reduce muscle cramps when sodium intake is adequate
  • Convenient, ready-to-drink hydration option

HEALTH BENEFITS

  • Electrolytes are crucial for nerve/muscle function and hydration
  • Sodium aids fluid retention during intense exercise or heat
  • Potassium supports heart rhythm and electrolyte balance
  • Magnesium (if included) may reduce cramping and fatigue
  • May improve perceived endurance in long sessions
  • Helps prevent dilutional hyponatremia when hydrating heavily

PREPARATION SUGGESTIONS

DURING WORKOUT

Sip a sugar-free sports drink during cardio or high-intensity sessions to replace electrolytes lost in sweat.

POST-WORKOUT RECOVERY

Have one after exercise to replenish sodium/potassium alongside water and a protein-rich meal.

DURING FASTING WINDOW

Use an unsweetened or minimally sweetened electrolyte formula during extended fasts to maintain hydration and minerals.

INTENSE TRAINING

For multi-hour training, alternate sips of sports drink and water; target 300–600 mg sodium per hour depending on sweat rate.

HOT WEATHER HYDRATION

In hot climates, include electrolytes to replace sweat losses more effectively than plain water alone.

MIXED WITH WATER

Dilute with water to taste if the flavor is strong; aim for light, steady sipping rather than large gulps.
