The Claim

Ingestion of 0.7% or 0.9% sodium chloride solutions results in a net fluid balance that is 211–329 mL greater compared to water in resting, euhydrated young men, due to reduced urine output and maintenance of plasma osmolality.

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.

How it works
1 study reviewed
In plain English

If young, healthy guys at rest drink salty water (with 0.7% or 0.9% salt), they hold onto more fluid than if they drank plain water—because they pee less and their body fluids stay balanced.

What the research says

1 study
  1. Study: Carbohydrate hastens hypervolemia achieved through ingestion of aqueous sodium solution in resting euhydrated humans

    The study found that drinking salty drinks (with 0.7% or 0.9% salt) helps the body hold onto more fluid than drinking plain water, because people pee less and their body fluids stay balanced.
