The Claim

The addition of glycerol and electrolytes to a beverage has no adverse effect on fluid balance in healthy adults over an 8-hour period, as indicated by consistent positive net fluid retention and absence of reported adverse events.

Source: Time-course changes in fluid balance following ingestion of a novel glycerol-electrolyte solution in a randomized trial.

Description
1 study reviewed
In plain English

Drinking a beverage with glycerol and electrolytes does not disrupt fluid balance in healthy adults over 8 hours, as the body retains more fluid than it loses and no negative effects were observed.

See the scientific wording

The addition of glycerol and electrolytes to a beverage does not appear to cause adverse effects on fluid balance in healthy adults over an 8-hour period, as net fluid retention was consistently positive and no adverse events were reported.

Why this might work

When glycerol and electrolytes are swallowed, they enter the blood and make the fluid thicker, which tells the kidneys to hold onto more water instead of peeing it out. The electrolytes help keep the fluid volume up and prevent the kidneys from flushing out extra water, so the body keeps more fluid inside.

1 study
  1. Study: Time-course changes in fluid balance following ingestion of a novel glycerol-electrolyte solution in a randomized trial.

    People who drank this special water with glycerol and electrolytes kept more fluid in their bodies and peed less than those who drank plain water, with no side effects reported — so it didn’t hurt their fluid balance.
