SUGGESTED USE

Add one sachet (4.1g) to 16–17 oz (500ml) of cold water. Stir or shake until fully dissolved.

Consume 5-6 oz (150-175 ml) every 20 minutes during exercise. Best enjoyed immediately after mixing.

CREATED BY SCIENCE

Research indicates that dehydration exceeding 3% of body mass impairs physical performance, particularly in warm or hot environments. When you sweat, you lose fluids and electrolytes, so replacing both is key to avoiding dehydration and staying at your best. HYDRO+ provides an optimal balance of electrolytes to help sustain hydration and performance during training, competition, or recovery.

DRINK BEFORE EXERCISE

Hydration starts before you train. Experts recommend drinking around 6-8 glasses of fluid per day, roughly 2,000ml for men and 1,600ml for women; and if the weather is hot or we are exercising, we need to drink even more.

For a 155-pound athlete, that’s about 12–24 oz (350–700ml) before activity. Proper pre-exercise hydration helps prevent early fatigue, maintain focus, and prepare your body for performance, especially in high heat or humidity.

Stay Hydrated

Sweating leads to fluid and electrolyte loss, which can reduce blood volume and slow muscle recovery. On average, athletes lose 1.25–10 cups (0.3–2.4 liters) per hour through sweat. When dehydrated, heart rate rises, effort feels harder, and body temperature climbs faster. Starting your session hydrated and replacing lost electrolytes during training helps regulate temperature, maintain endurance, and delay fatigue.

The Role of Electrolytes

Each serving of HYDRO+ delivers 1,576mg of electrolytes, including Potassium, Chloride, Calcium, Magnesium, and Sodium, to replace what’s lost in sweat and support rapid rehydration.

What’s Inside Each Stick:

  • 120mg Calcium to help maintain strong bones and muscle function

  • 56mg Magnesium for muscle contraction and electrolyte balance

  • 350mg Sodium and 750mg Chloride to replace salts lost through sweat

  • 300mg Potassium to support normal muscle function

Daily Electrolyte Needs

Electrolyte requirements vary based on activity, environment, and individual sweat rate. On average:

  • Sodium: Aim for less than 2,400mg daily

  • Potassium: Around 3,500mg per day

  • Magnesium: 300mg for men, 270mg for women

  • Calcium: 700mg daily for adults

Optimal Electrolyte Balance for Performance

HYDRO+ has been scientifically engineered to deliver the right electrolyte ratio for performance hydration. Fluid intake during exercise should prevent fluid losses greater than 2% of body weight. The sodium and electrolyte blend in HYDRO+ supports hydration, thermoregulation, and performance without the excess sodium typical of ultra-endurance products.
