Electrolytes are delivered to your blood via a process called osmosis, which is the movement of water in and out of the cells. Many alternative electrolyte formulas on the market are isotonic or hypertonic solutions. Isotonic solutions are in equilibrium with their surroundings, meaning there is no significant movement of water in or out of the cells. Hypertonic solutions have a higher solute concentration, causing water to move out of cells and actually dehydrating you, which can result in gastric distress. True's Electrolyte is a hypotonic solution, meaning it has a lower concentration of dissolved particles and can be absorbed by the gut walls faster than isotonic and hypertonic formulas or even water alone.
