The Claim
Ingestion of a glycerol-electrolyte solution results in a peak net fluid balance difference of 0.23% and a reduction in urine output of 159 grams between 2 and 4 hours post-ingestion, indicating a delayed but sustained physiological effect on fluid retention.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Drinking a glycerol-electrolyte solution leads to a 0.23% increase in net fluid balance and 159 grams less urine produced between 2 and 4 hours after consumption, showing that fluid retention peaks during this window and remains elevated.
See the scientific wording
The fluid retention benefit of a glycerol-electrolyte solution is most pronounced between 2 and 4 hours after ingestion, with peak differences in net fluid balance of 0.23% and urine output reduction of 159 grams, indicating a delayed but sustained physiological effect.
When glycerol and electrolytes are swallowed, they enter the blood and make the fluid there thicker, which tells the kidneys to hold onto more water instead of sending it out as urine. The electrolytes help keep the fluid volume up and prevent the kidneys from flushing out extra water. This keeps more fluid in the body for several hours, with the strongest effect happening 2 to 4 hours after drinking.
What the research says
1 studyThis study found that drinking this special fluid keeps more water in your body and makes you pee less, and the best effect happens 2 to 4 hours after drinking — just like the claim says.
