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.
L-carnitine is an amino acid that is crucial for fat metabolism because it ensures that long-chain fatty acids are transported to the mitochondria where they are converted into energy.
Vitamin C is an important antioxidant that protects our cells from oxidative stress. It is necessary for the normal functioning of bones, teeth, cartilage, gums, skin and blood vessels.
Magnesium plays a key role in maintaining the normal functioning of the nervous system and muscles and supports energy metabolism and electrolyte balance. With magnesium citrate, the form that allows the best absorption and bioavailability, you can replace lost magnesium and avoid deficiencies that can manifest as unpleasant fatigue, lack of energy and muscle dysfunction, especially as frequent muscle cramps.
Calcium is a mineral that is very important for maintaining strong bones and teeth. Calcium citrate, a natural form of calcium, can help replace lost calcium in the body. The most common result of calcium deficiency is brittle bones and teeth, but muscle cramps, aches and pains and excessive fatigue can also occur.
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 their common function, each of the B vitamins has other important roles in our bodies. 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 also acts as an antioxidant, protecting our cells from oxidative stress.

I recently started a new job which requires a lot of physical activity and I was struggling to keep up with the demands of the job. Isotonic has been a lifesaver for me. 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.
