The Claim
A caffeinated energy drink containing approximately 106 mg of caffeine, 44.7 mmol of sodium, and carbohydrates has hydration properties statistically indistinguishable from water in healthy adults when measured by the Beverage Hydration Index at 240 minutes.
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.
A caffeinated energy drink with 106 mg of caffeine, electrolytes, and carbohydrates hydrates the body as effectively as water in healthy adults after 240 minutes, according to the Beverage Hydration Index.
See the scientific wording
A caffeinated energy drink containing approximately 106 mg of caffeine, electrolytes (44.7 mmol sodium), and carbohydrates has hydration properties statistically indistinguishable from water in healthy adults, as measured by the Beverage Hydration Index (BHI) at 240 minutes, suggesting that specific formulations can maintain fluid balance despite caffeine content.
When a drink contains caffeine, sodium, and sugar, the sodium and sugar help the kidneys hold onto more water instead of flushing it out. The caffeine tries to make the kidneys produce more urine by blocking signals that normally keep sodium in the body, but the extra sodium and sugar in the drink trick the kidneys into reabsorbing more sodium and water, so the body keeps the fluid just like it would with plain water.
What the research says
1 studyThis energy drink with caffeine, salt, and sugar hydrates just as well as water — unlike other caffeinated drinks that make you pee more. The study proved it by measuring how much fluid the body keeps after drinking.
