Frequently asked questions
What are electrolyte tablets and how do they help in sport?
They give you sodium, potassium and magnesium, the minerals you lose in sweat. They help you stay hydrated, keep your muscles working and prevent cramp. Use them before, during or after hard sessions.
How do I choose the best electrolyte tablets for me?
Think about your sport, how long you train and how hard. Look for a balanced mix of electrolytes with little added sugar, and test a few in training.
When is the best time to take electrolyte tablets?
Before and during long sessions, especially if you sweat a lot. Have one in water about 30 minutes before training and more each hour in hard sessions.
How do I know if I need electrolyte tablets?
Fatigue, cramps or headaches in training can be signs. Track your sweat rate and use them after hard sessions over 60 minutes, especially in the heat.
Can I use electrolyte tablets outside sport?
Yes. They're useful for hiking, long trips and hot weather, or any long stretch of effort.
How should I store electrolyte tablets?
Keep them somewhere cool and dry, out of direct sunlight, in their original container or a sealed bag. Use them before the date on the pack.
