The Claim

The inclusion of electrolytes and carbohydrates in caffeinated energy drinks reduces fluid loss compared to caffeinated drinks without these components, as evidenced by a 24.8% greater fluid retention over 240 minutes in the formulation containing electrolytes and carbohydrates.

Cause and effect
1 study reviewed
In plain English

Energy drinks containing electrolytes and carbohydrates retain 24.8% more fluid over 240 minutes than drinks with caffeine alone.

See the scientific wording

The presence of electrolytes and carbohydrates in caffeinated energy drinks can offset the fluid loss associated with high caffeine doses, as demonstrated by a 240-minute fluid retention difference of 24.8% between CAF (−71.2%) and CAF + CE (−46.4%), suggesting formulation is more critical than caffeine alone.

Why this might work

When a drink contains salt and sugar along with caffeine, the salt and sugar help the kidneys hold onto more water instead of flushing it out. The salt pulls water back into the body through the kidney tubes, and the sugar helps carry more salt back in, which stops the caffeine from making the body lose too much water.

  1. Study: Caffeinated Energy Drink Formulations Differentially Impact Hydration Versus Water: Does Habitual Caffeine Intake or Biological Sex Matter?

    Adding salt and sugar to a high-caffeine drink helps your body keep more water, even if it still has caffeine. The study found that drinks with salt and sugar kept fluid almost as well as water, while drinks without them made you lose much more fluid.
