First contact : The low osmolality of Prime (~270 mOsm/kg) means it is hypotonic relative to blood plasma. Water and electrolytes pass rapidly through the stomach wall without triggering osmotic resistance — faster initial absorption than isotonic sports drinks.
10 min : Sodium begins active transport across the intestinal epithelium via sodium-potassium ATPase pumps. Without glucose to activate SGLT1 co-transport, absorption relies more heavily on the elevated sodium concentration gradient.
30 min : Potassium from coconut water concentrate reaches the bloodstream, restoring intracellular electrolyte balance. BCAAs begin intestinal absorption — slow relative to amino acid isolates but bioavailable within the 30-minute post-exercise window.
45 min : Plasma sodium stabilizes. The sucralose sweetener is largely excreted unmetabolized — no insulin spike, no glycemic disruption. The hydration effect peaks as water follows the sodium gradient into cells via aquaporin channels.
5–6 hour half-life : Electrolytes fully distributed. The BCAA contribution is complete. Unlike sugar-based sports drinks, there is no glycemic descent — hydration status is maintained without the blood glucose cycle that accompanies Gatorade or Powerade.
