The Science Behind
Better Hydration.
Why Osmolality Matters More Than Anything Else in a Hydration Drink
Osmolality measures how concentrated a drink is. It tells you how fast your body can absorb fluid from your stomach into your bloodstream.
1. Lower Osmolality = Faster Absorption
- Drinks below 200 mOsm/kg are called hypotonic.
- Hypotonic solutions move across the intestinal wall faster than any other type, delivering water and electrolytes into the bloodstream rapidly.¹²
- Better Beings sits at an optimal 60–75 mOsm/kg, meaning it is absorbed significantly faster than ORS, sports drinks, or sugar-based hydration powders.
2. High Osmolality Slows Hydration ³⁴
- Drinks around 250–330 mOsm/kg (like sports drinks or sugar-heavy electrolyte powders) are isotonic, meaning your stomach must “balance” them before they can be absorbed.
- This slows gastric emptying and delays hydration.
3. Why Better Beings Hydrates 3x Better
Better Beings is engineered to be both:
- Hypotonic (60–75 mOsm/kg) → super-fast absorption ⁵
- Electrolyte-dense (~1300 mg) → superior retention compared to water
- Zero sugar → no spike in osmolality, no crash, no slowdown
Your body doesn’t have to work to dilute or digest the drink — it just absorbs it.
This is why elite sports academies and hydration scientists consistently recommend hypotonic drinks for rapid hydration.
