The purpose of this study was to investigate the differences in the intestinal fluid absorption rates between an ion supply drink and water using rats.


The ion supply drink and water which contained radioisotope (tritium) as a tracer were orally administered to Wistar strain male rats, and their absorption rate was measured by changes in the tracer content in the blood.


The ion supply drink was 2.3 times more rapidly transferred to the blood from the intestinal tract and was more quickly absorbed compared to water.


This study shows that the ion supply drink is more rapidly absorbed than water, suggesting that it is useful to quickly and adequately replenish fluid and electrolytes.
