SPONSER® Hydration Preloader

A specialized hydration drink designed to be consumed before training or racing in hot conditions. It helps prepare your body for heat stress and creates an optimal hydration base for endurance performance.

It provides electrolytes—especially sodium—along with carbohydrates and L-citrulline, making it ideal for preparing the body for heavy sweating and prolonged exercise in warm environments.

What is plasma volume and why is it important for athletes?

Plasma is the liquid component of blood, accounting for approximately 55% of its total volume. It consists mainly of water, proteins, and electrolytes. Maintaining plasma volume is essential for endurance performance, as it supports cardiovascular function, thermoregulation, and oxygen transport. Since water makes up the majority of plasma, its volume depends heavily on nutrients such as sodium, which has a high water-binding capacity.

Benefits of increasing plasma volume

Improved performance – A higher plasma volume increases total blood volume, which improves stroke volume and supports a higher VO₂max.

Better cooling (thermoregulation) – More plasma means more water is available for regulating body temperature. This allows more blood to be directed to the skin to dissipate heat efficiently.

Enhanced endurance – Dehydration causes blood to become more viscous, forcing the heart to work harder. Increasing plasma volume helps maintain better blood flow and reduces cardiovascular strain.

Better prepared for the start – Higher sodium stores before exercise, combined with hydration during activity, help compensate for fluid and electrolyte losses caused by sweating.

• Targeted pre-hydration before races and intense training sessions
• 1000 mg of sodium per serving to support fluid retention
• 20 g of carbohydrates for a controlled energy boost before exercise
• Enriched with L-citrulline, a non-essential amino acid and precursor to L-arginine involved in nitric oxide metabolism

Directions for use
Dissolve one serving (28 g) in water. Consume approximately 60–90 minutes before training or racing in hot conditions. Drink slowly in small sips.

Important: Do not exceed the recommended daily intake (28 g). Food supplements should not be used as a substitute for a varied, balanced diet and a healthy lifestyle.
Keep out of reach of young children.
