The Science of Hydration

What does "isotonic" mean?

The term isotonic means that the fluid has the same concentration as your blood stream. This means that when you ingest it, other fluid does not shift into your gut to dilute it; instead, the fluid in the isotonic drink just readily crosses over into the bloodstream. Consuming an isotonic drink quickly replaces the fluids lost by sweating and provides a boost of carbohydrates.

What are electrolytes?

Electrolytes regulate our nerve and muscle function, our body’s hydration, blood pH, blood pressure and the rebuilding of damaged tissue. The major electrolytes found within the body include calcium, magnesium, potassium, sodium, phosphate and chloride. The precise mix of electrolytes provide superior rehydration during fitness activities and sports. All Yeti drinks contain the 5 main electrolytes. 

Why are B-Vitamins important for recovery?

B-Vitamins convert proteins and sugars into energy. B-Vitamins increase the body’s ability to repair itself, operate efficiently and fight disease. Yeti Isotonic contain Vitamin B7 (Biotin), Vitamin B6, Vitamin B5 (Pantothenic Acid) and Vitamin B12.

Superior hydration with Yeti

You lose a lot more than water when you sweat, including critical electrolytes that help your brain communicate with muscles and regulate your body’s fluid balance. Significant losses in fluids and electrolytes can negatively impact performance, especially during long bouts of training.


During challenging athletic events, it is not uncommon for athletes to lose 6–10% of body weight in sweat loss, thus leading to dehydration. Decrements in physical performance in athletes have been observed under much lower levels of dehydration, as little as 2%. At 2% loss of body weight through sweat loss, your performance will drop by over 15%.


Yeti Isotonic sports drink has been designed to be in balance with your body's fluids to give you fast hydration and energy when you need it most. For those who train hard and push their body to the limits, sports drinks can be a key component to maintaining performance. Water alone isn't enough when you are playing intensive or endurance sport. Your body needs more.


Yeti Isotonic contains the precise mix of electrolytes for superior rehydration and comprehensive mix of B-vitamins for recovery and energy. 


No wonder it's the #1 sports drink in Sri Lanka!
