Do drinks and powders with electrolytes help to hydrate you better?

Listener Rob got in touch as he’s recently taken up a new sport and wants to know if electrolytes can help his performance and recovery. He’s seen lots of adverts on social media for drinks and powders containing electrolytes that claim to hydrate you better than just plain water. But do they?

To find the answers, Greg speaks to Graeme Close, Professor of Human Physiology and Head of the Research Institute for Sports and Exercise Sciences at Liverpool John Moores University.
