ELECTROLYTES — DO YOU NEED THEM? 💧
Electrolytes are a common addition to sports drinks and supplements — but do you actually need to be taking them?
This post covers:
💧 What electrolytes are & why they matter
🧂 The key electrolytes — sodium, potassium & magnesium
☀️ Why exercise duration, heat & sweat rate matter
🎯 Whether you actually need an electrolyte supplement
The verdict? 4/5 ⭐️
Electrolytes are essential minerals that play important roles in hydration, muscle function and nerve signalling. But that doesn’t mean everyone needs an electrolyte supplement everyday
For most everyday training, a balanced diet and adequate fluid intake will provide what you need. However, during longer sessions (>60 minutes), training in hot conditions or if you’re a heavy/salty sweater, replacing electrolytes — particularly sodium — is beneficial.
As always, food first and supplements when they add value. Get the fundamentals right before spending money on another supplement.
