Stay Hydrated and Perform at Your Best with Isotonic

The Ultimate Electrolyte Drink

Proper hydration is essential for overall health and well-being, especially during physical activity.

When we sweat, we lose important electrolytes that are crucial for our body's normal functions. That's where Isotonic comes in.

Our instant isotonic drink is specially formulated with carbohydrates and electrolytes to help replace what we lose through sweating.

With added L-carnitine, Vitamin C, Magnesium, Calcium, and B complex, Isotonic not only helps with hydration, but also contributes to normal energy metabolism, muscle functions and immune system support.

Whether you're an athlete, a busy professional, or just looking for an extra boost, Isotonic can help you stay properly hydrated and perform at your best.

WHY IT WORKS?

1 L-carnitine

L-carnitine is an amino acid that is key to fat metabolism because it ensures that long-chain fatty acids are transferred to the mitochondria, where they are converted into energy.

2 Vitamin C

Vitamin C is an important antioxidant that protects our cells from oxidative stress. This powerful antioxidant contributes to the protection of cells against oxidative damage, which is important for overall health. It also supports immune system function by helping to increase the production of white blood cells, which help fight off infections.

3 Magnesium

Magnesium plays a crucial role in maintaining normal nervous system and muscle functions, as well as supporting energy metabolism and electrolyte balance. With Magnesium citrate, a form that allows the best absorption and bioavailability, you can replace lost magnesim and avoid deficency, which can manifest as unpleasant fatigue, lack of energy and muscle dysfunction, especially as frequent muscle cramps.

4 Calcium

Calcium is a mineral that is very important for maintaining strong bones and teeth. With calcium citrate, a natural form of calcium, you can help replace lost calcium in the body. The most common consequence of calcium deficiency are brittle bones and teeth, also muscle cramps, pains and excessive fatigue may occur.

5 B complex

The B complex is a group of vitamins B1, B2, B6, B12, folic acid, pantothenic acid and niacin, which are important for our nervous system. In addition to the common function, each of the B vitamins has other important roles in our body. Vitamins B1 -5 and B12 work against fatigue and exhaustion. Folic acid is important for the normal functioning of the immune system. Vitamin B2 is important for the absorption and metabolism of iron, and it also acts as an antioxidant and protects our cells from oxidative stress.

It keeps me hydrated and provides the energy I need to get through the day. I also love that it has added vitamins and minerals that contribute to normal psychological functions. I feel more focused and alert throughout the day.

 

Why it’s important te replace lost electrolites?

 

Electrolytes are minerals in your body that carry an electric charge when dissolved in fluids like blood or bodily fluids.

 

These minerals are essential for various physiological processes and play a crucial role in maintaining proper hydration, nerve function, muscle function and maintaining the balance of fluids in your body.

 

When you engage in physical activity, your body sweats, and in turn you lose essential electrolytes.

 

Replenishing them is crucial to maintain proper bodily functions, especially during physical activity.

 

Replenish lost electrolytes with Isotonic

 

Restore the crucial balance required for peak performance.

 

Whether you’re an athlete, a fitness enthusiast, or simply engaging in regular physical activity, replacing lost electrolytes will help you stay hydrated, improve muscle function, enhance nerve signaling, and maintain fluid balance.

 

Don’t let electrolyte depletion hinder your performance – prioritize replenishment for optimal results!
