The Facts
A Comparison of 12 oz of TRUE Hydration and 16 oz of Water - research conducted in 2024 by University of California, San Diego.
Objective
To determine True Hydration's performance vs. 16 oz of plain water in Rapid Hydration: The series of graphs below show the change in hydration status from Baseline to 60 minutes after drink consumption.
Methods
All subjects participated in both conditions on separate days one week apart. Subjects fasted (no food or drink for two hours) before testing. Subjects were tested upon arrival at the test facility (baseline) before consuming either 12 oz of TRUE or 16 oz of Water (order randomly assigned). Subjects were tested again after consumption of the drink.
1. Changes in Body Fluid Composition
Body fluid composition was assessed using a clinical impedance measurement device. As shown in the Figure below, at 60 minutes post-ingestion, TRUE resulted in a greater measurable body water, and more notably, more of that water was at the intracellular level indicating superior absorption & retention to the cells.
2. Changes in Blood Hematocrit Levels
Hematocrit is the percentage of red blood cells in your blood. When a person is dehydrated, the hematocrit will appear higher than if the patient were normally hydrated due to a decrease in dilution. As shown in the Figure below, at 60 minutes post-ingestion, TRUE resulted in a decrease in hematocrit levels indicating an increase in hydration status. This is compared to water that showed an increase in hematocrit levels indicating a decrease in hydration status.
3. Changes in Skeletal Muscle Fluid Mass
Skeletal muscle fluid mass is a measure of the amount of fluid present in the muscles directly attached to the skeletal structure. This measure is relevant for hydration as dehydration of the skeletal muscles is associated with cramping and other issues. As shown in the Figure below, at 60 minutes post-ingestion, TRUE resulted in a greater increase in the amount of fluid present in the skeletal muscles as compared with water.
