The Claim

The interaction between glycerol concentration and time significantly influences fluid balance in healthy, active adults, with glycerol’s effect on fluid retention increasing over the first 210 minutes after ingestion.

Source: A randomized trial modeling the effects of solutions with low to moderate glycerol and sodium concentrations on fluid balance in healthy, active adults.

How it works
1 study reviewed
In plain English

In healthy, active adults, the amount of glycerol consumed and the time elapsed after ingestion together determine how much fluid the body retains, with fluid retention increasing steadily over the first 210 minutes.

See the scientific wording

The interaction between glycerol concentration and time significantly influences fluid balance in healthy, active adults, indicating that glycerol’s effect on fluid retention increases over the first 210 minutes after ingestion.

Why this might work

When glycerol is swallowed, it enters the blood and pulls water into the bloodstream by increasing the concentration of dissolved particles. This signals the kidneys to hold onto more water instead of letting it leave as urine. The longer glycerol stays in the blood, the more water the kidneys keep, especially when sodium is also present. This keeps body weight higher for longer because less fluid is lost.

  1. Study: A randomized trial modeling the effects of solutions with low to moderate glycerol and sodium concentrations on fluid balance in healthy, active adults.

    The study found that when people drink drinks with glycerol, the longer it stays in their body, the better it helps them keep water in — especially after about 3.5 hours.
