“Saltiest electrolytes in the game.”
Saltiest electrolytes in the game! It’s what we always wanted – top tier and a must in my training and nutrition not just for running but fitness across the board.

“No more headaches post run.”
I get very sweaty when running – so much so you could exfoliate my face with the salt deposits! I recover much better from my runs and can get on with my day with no headache.

“Not left feeling totally run ragged.”
I lose a lot of sweat during my runs and find these salty electrolytes to work amazing. They definitely replace what I’ve lost so I’m not left feeling totally run ragged post race.

“When I don’t use these I get muscle cramps.”
I run a few times a week and find when I don’t use these that I get muscle cramps. At first I wasn’t sure about the salty taste but they’ve really grown on me.

Felt the difference from the first packet. The taste is very salty but that’s to be expected when you’re replenishing the sodium in your system after a tough workout.

Electrolytes are most useful when they solve a real problem: replacing the key minerals lost in sweat, particularly sodium. For longer runs, hot conditions, or athletes with higher sweat losses. Puresport Electrolytes provide a practical way to support fluid balance, great tasting and a simple formula that delivers sodium, potassium, magnesium and calcium.
Anyone who sweats: runners, cyclists, gym-goers and everyday active people who want to replace the sodium and minerals lost through sweat.
Each 30-pack contains 30 servings. Used daily that is roughly one month; used only on training days it lasts considerably longer.
Most people feel better hydration and energy within the first few sessions, especially on longer or hotter efforts.
Yes. One serving a day is well within healthy sodium guidelines for active people. Increase intake around heavy training or hot weather.
Our powder delivers a high, precise dose of electrolytes with zero sugar, unlike most sports drinks that are diluted and sugar-heavy.
Mix one sachet with 500ml of water. Adjust to taste with more or less water depending on your preference.
Alcohol is dehydrating, so replacing fluids and electrolytes can help you feel more human the morning after.
Both have their place. Supplements give a fast, measured dose that is hard to match from food alone around intense exercise.
