This one is going to ruffle some feathers 💦
Look anywhere in the sport space and you are going to see ads and recommendations for electrolyte supplements with ever increasing sodium contents but do we actually need them?
The main mistake I see many athletes making is focusing on sodium losses via sweating during training in isolation. Yes we lose sodium but our body is pretty amazing at trying to keep us in balance by reducing the amount we lose via sweat and urine + we need to consider what our fluid intake is. Less fluid consumed during = more concentrated sodium in the blood. More fluid consumed during training over long periods of time = more dilute sodium in the blood (which can be a concern).
We need to switch the script to focusing on optimizing fluid first to support health and performance, and focus on sodium/electrolyte amounts second.
