There’s been a lack of clear guidelines around how much sodium to take before, during and after exercise, to optimise health and performance. That created a vacuum, which anyone with a vested interest was more than happy to fill with suggestions. But we’re now getting to the stage where we can make some more specific, quantifiable recommendations about sodium for endurance athletes, before, during and after exercise. I had the privilege of being invited to put these recommendations together, so in this episode, I’ll walk you through them.
