About this episode

Dr Nicola discusses the science of electrolytes, their benefits, and when supplements are necessary.

Electrolytes are everywhere right now, in powders, drinks, and all over social media — but do you actually need them? In this episode of Dr Nicola’s Second Opinion, Dr Nic breaks down the science, explaining what they are, how they support your body, and when supplements can actually be useful. She also answers your questions about post-workout hydration, sweating in hot weather, and what you should look for in an electrolyte product. Plus, Dr Nic shares simple advice on when water and a balanced diet are enough on their own, and when it might make sense to reach for extra support.
