How are sport drinks supposed to hydrate you more than drinking water?
In: Biology
Everyone in here is… really fucking this up. Here’s the answer.
We have several channels in our gut lumen whose purpose is entirely for the cotransport of a few ions, glucose, and WATER together. This is the basis of oral rehydration therapy, and is one of the most major discoveries in the combat of diarrheal infections like cholera in developing nations.
SGLT-1 is the name of a sodium-glucose transporter in the channel in the gut. This channel, coupled with a few ATPases on the other end of the epithelial cells create a downstream gradient for the ions, and cycling of this duo also draws loads of water in.
