Hydration is a priority

Very simply, water is vital for normal bodily functions and it also makes up the majority of your body weight. As you go about your day, you naturally lose water, and it is recommended that you drink fluids regularly throughout the day to combat this loss. THIRSTI natural spring water is perfect for this!

However, when it comes to exercising, staying hydrated means more than simply drinking water! If you are exercising for long periods of time – and sweating a lot as a result – then you need more than just plain H20.

This is largely because the essential salts – electrolytes – your body also needs are lost through sweat, and need to be replaced.


Hydrated during exercise

Hydration is vital during physical activity and, whether you’re an athlete or not, you need to be very intentional about watching your fluid intake. Plain water is great for your first hour of exercise but after that time, important electrolytes are lost in greater number through sweat and need to be replenished.

That’s where ISOFIT+ comes in! Our electrolyte-fuelled sports drinks are designed for continued activity lasting beyond one hour.

Sports drinks and

Short duration exercise

Although it is not necessary to drink sports drinks for short-duration exercise, research has shown that overall fluid intake increases with added flavour when compared to normal water. Ultimately this means that the better something tastes, the more of it you’re willing to drink! This is beneficial no matter how long you are exercising for.

With ISOFIT+ in 4 powerful flavours: Berry, Blueberry, Naartjie and Lemon Lime – there’s definitely a favourite for everyone!

To improve athletic performance

The real health benefits of drinking sports drinks include increased energy to aid extended periods of intense training and, most importantly, to replace important electrolytes lost through sweat during exercise.

Our sports drinks have our natural spring water as their base ingredient. The main carbohydrate, glucose, is then added to provide much-needed energy. Sugar is an important substance for exercise as it fuels activity. The specific amount of sugar in ISOFIT+ has been carefully calculated to ensure that it is at an optimal level for performance.

The importance of

Replenishing electrolytes

Sports Drinks help to rehydrate your body and restore your electrolyte balance during prolonged activity. This is very important for your essential organs such as your brain, muscles, and nerves.

Electrolytes are minerals that keep the body’s balance of fluids at the proper level. Examples of electrolytes include potassium, calcium, sodium, chloride and magnesium. Sports drinks, such as ISOFIT+, are great for replacing electrolytes in your body during intense exercise.

  • Calcium helps to build and maintain strong bones. Your heart, muscles and nerves also need calcium to function properly.
  • Magnesium contributes to the maintenance of normal muscle function, bones, and the electrolyte balance.
  • Sodium balances fluids in the body and it influences blood pressure. It helps to send nerve impulses and it is needed for muscle contractions.
  • Potassium enhances muscle strength and assists with metabolism, water balance, electrolytic functions, and the nervous system. It also helps to combat anxiety and stress.

When you drink ISOFIT+, you are hydrating your body as well as replenishing electrolytes that are lost during exercise.
