Tablets are cheap yes. But most tablets are filled with laxatives, artificial sweeteners, and other funky ingredients. GoodDay™ isn’t.
Free from caffeine, laxatives, coating agents, anti-caking agents, colorants, and artificial sweeteners. No weird stuff. No kitchen-sink chemistry. Just clean, functional hydration.
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.
GoodDay™ was proudly born on the streets of Copenhagen – Allegade 13 to be exact.
The powder is mixed in Germany and packaged her in Denmark.
