You want powder, not tablets. Here’s why.
Most tablets are filled with laxatives, artificial sweeteners, and other funky ingredients. GoodDay™ isn’t.

Surprisingly effective.
Unlike a lot of our competitors, GoodDay™ is based on biology - not trends. Essential electrolytes in a balanced ratio. Topped with sugar to activate the sugar-glucose transport system. Finished with a subtle flavour and you get a clean, effective and surprisingly delicious electrolyte drink.
Made in Denmark
Made in Denmark
Despite it being gloomy 9 months of the year, Danes love exercising outdoors. We do too, but we didn’t love the electrolytes on the market. GoodDay™ was proudly born on the streets of Copenhagen – Allegade 13 to be exact.
The powder is blended in Germany and packaged her in Denmark.
Third party tested
GoodDay™ is tested by Informed Sport—an independent, third-party certification program that screens for banned substances in sports. Every batch is tested before it hits the market, so you know exactly what you’re getting. No shortcuts, no guesswork. Just clean ingredients, verified by a lab that has no stake in the product. Trusted by athletes, backed by science.
Based on biology, not trends
Drinks with a hypotonic osmolality (<275 mOsm/kg) are best at maintaining blood plasma volume during exercise. They’re absorbed faster and keep you better hydrated [Rowlands et al., 2022].
The body uses a co-transport system (SGLT1) in the small intestine that requires both sodium and glucose to pull water into the bloodstream efficiently. A 1–4% sugar concentration hits the sweet spot: fast absorption, minimal gut discomfort.
More salt isn't better. You rarely need more than 460 mg of sodium per liter. The point isn’t to replace massive salt losses—it’s to support absorption through osmosis. Overdoing salt just stresses your system.
Short ingredienslist, no bs
GoodDay™ is made with the same care (and simplicity) as if you mixed it yourself at home. Just the essentials: electrolytes, a touch of glucose, natural flavor. That’s it.
Free from caffeine, laxatives, coating agents, anti-caking agents, colorants, and artificial sweeteners. No weird stuff. No kitchen-sink chemistry. Just clean, functional hydration.
Sorry, but you won’t be a first mover
More than 80.000 have had a GoodDay™ so far.

Frequently asked questions
What are electrolytes?
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.
Why did you add sugar?
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 (8 g per serving - 32 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.
Do I really need electrolytes?
Yes - electrolytes are essential minerals your body can’t function without. Luckily, most people get enough through food.
But in certain situations - like heavy sweating, long travel, or dehydration - you lose more fluids and salts than usual. That’s when an electrolyte drink can be helpful.
Electrolytes like sodium, potassium, and magnesium help regulate fluid balance. When that balance is off, your body doesn’t absorb or hold onto water as well. That’s where GoodDay™ comes in.
You might find it useful:
- After longer workouts (like running or cycling for over an hour)
- In hot environments or sauna sessions
- After a night out
- During or after long-haul flights
- When you haven’t had much to drink for a while
In these moments, a drink like GoodDay™ can help your body rehydrate more efficiently - with a science-backed blend of electrolytes and a touch of glucose.
How many should I drink per day?
It depends on how much fluid you lose. If you’re sweating a lot, active for long periods, or in a hot environment, you might benefit from more than one serving. On slower days, you might not need any.
GoodDay™ is formulated to stay within safe electrolyte levels - so it’s fine to use multiple servings on days when your fluid needs are higher.
When can I expect my product?
We ship every weekday with DAO. You’ll typically receive your order 1–3 weekdays after it's been confirmed.
