The Claim
Ingestion of a 1-liter novel glycerol-electrolyte solution containing 0.75% glycerol, 40 mmol/L sodium, and other electrolytes increases net fluid retention by 0.15% over 8 hours compared to a flavored placebo in healthy adults, primarily due to reduced urine output.
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 specific 1-liter fluid with 0.75% glycerol and 40 mmol/L sodium causes a 0.15% greater increase in fluid retention over 8 hours than a flavored water placebo in healthy adults, because less urine is produced.
See the scientific wording
Ingestion of a 1-liter novel glycerol-electrolyte solution containing 0.75% glycerol, 40 mmol/L sodium, and other electrolytes increases net fluid retention by 0.15% over 8 hours compared to a flavored placebo in healthy adults, primarily due to reduced urine output, suggesting glycerol-electrolyte formulations may modestly enhance short-term fluid balance maintenance.
When a person drinks a solution containing glycerol and electrolytes, the glycerol enters the blood and pulls water into the bloodstream, making the blood slightly thicker. This signals the kidneys to hold onto more water instead of sending it out as urine. The electrolytes, especially sodium, help keep more fluid in the blood vessels and further reduce urine production. Together, this causes the body to keep more water for several hours.
What the research says
1 studyDrinking this special sugary-salty drink with glycerol made people keep a little more water in their bodies and pee less over eight hours than when they drank plain flavored water.
