Could a new whey drink beat water for hydration in kids?
NCT ID NCT06967454
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested how well three different drinks—water, semi-skimmed milk, and a whey permeate drink—keep children aged 9 to 11 hydrated. Thirteen healthy kids took part, drinking each beverage on separate days. Researchers measured urine output, blood sugar, and even mood to see which drink worked best. The goal is to find a tasty, effective way to keep children hydrated.
