Do we actually need electrolyte supplements… or are they just another sector of the wellness industry with a really strong marketing team?

In this episode, we zoom out and look at how brands like Liquid IV and LMNT are marketed and why electrolytes have suddenly become part of everyone’s routine. We talk through what the research says about hydration, the controversy around sodium, and why for the average person, food and water are often enough.

This deep dive is for anyone who’s seen electrolyte packets everywhere and wondered, “Wait… should I be taking this too?”
