Your body constantly loses water - when you pee, sweat, drink coffee, and even when you breathe. If you don’t replace it, you can become dehydrated, leading to fatigue, poor focus, and low concentration.
This is where electrolytes gets in the picture: to help your body hydrate faster and more effectively, keeping you sharper during the workday.

Electrolytes are minerals your body uses to manage fluid balance and keep essential functions running—like muscle movement and nerve signaling. The key ones are sodium, potassium, magnesium, calcium, and chloride.
We lose electrolytes when we sweat—like during exercise, in the sauna, or on a hot summer day. We also lose them when we go to the bathroom—especially with diarrhea, after drinking alcohol (which is dehydrating), or just after a long day without enough water. And it’s primarily sodium that we lose.
That’s why our electrolyte powder is built around sodium, with added potassium and magnesium. Potassium and magnesium are lost in smaller amounts, but they still matter for muscle function and recovery. We’ve left out calcium, since Danish tap water is naturally high in it—most people get plenty from food and water already.
Sodium plays a special role. It helps your body absorb and distribute water through osmosis—aka the natural movement of water through cell membranes. When sodium is present in your gut, it pulls water into your bloodstream and out to your cells. Without enough sodium, much of the water you drink just passes straight through. That’s why sodium is essential for proper rehydration.
The short version? Anyone who loses more fluid than usual—and starts feeling it.
If you drink only water without any electrolytes, you risk diluting your body’s salt balance even more. That makes it harder for your body to retain fluid, and you can end up feeling flat, even if you’ve been drinking plenty. But that doesn’t mean you always need electrolytes. If you feel good, have been sipping water, and haven’t been sweating or peeing excessively—water is totally fine. It’s about knowing when your body needs a little more than just H2O.
Electrolytes make sense when you’re sweating or peeing more than normal. That can happen during exercise, in the sauna, when you’re sick, after drinking alcohol, or after a day where you simply forgot to hydrate. In those cases, you’re not just losing fluid—you’re also losing salts. And plain water isn’t always enough to fix that.
So when do electrolytes make sense? Here are the classics:
This isn’t about being extreme. It’s just about giving your body a little support, when it counts.
Mix the contents of 1 sachet with 400 ml of water. Stir or shake and consume within 24 hours. Store in a dry place at room temperature.
Drink around 200 ml at a time, to avoid a volume response leading to urination.
Consume before, during or after to support your hydration needs.
We get it—sugar gets a bad rap. And if you’re fasting, keto, or sugar-free, it makes sense. But for the rest of us? Sugar is actually a smart little helper—especially if you’re active.
Sugar = carbohydrates. Carbs = energy. So if you’re already sipping carb mixes, downing gels, or munching on energy bars, you’re in the club. But here’s the thing: energy isn’t even why we added it.
We added a small amount of sugar (7.5 g per serving—30 kcal or about 2% in diluted mix) for one simple reason: it helps your body absorb water and electrolytes more efficiently. Think of it as a fast track through your gut.
Here’s how: in your small intestine, there are transporter proteins called SGLT1—short for sodium-glucose linked transporter. These guys activate when both sodium and glucose (sugar) are present. Once activated, they pull water and electrolytes across the gut lining and straight into your bloodstream. That means faster, more effective hydration.
So no, sugar isn’t the villain. At least not here. It’s part of the solution.
