I thought I wouldn’t like the watermelon and it has become my favourite. Definitely recommend 100 percent. Game changer for me — no juice required to hide the taste.

“Train for longer, not so wrecked.”
Started using these for my training as I sweat a lot but was struggling with cramps and feeling just generally wrecked! I’m able to train for longer and not feel so awful after!

“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.

Verified Reviewer“Hands down the nicest tasting electrolytes I’ve ever had”
“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.

Verified Reviewer“Much better than expected... And I already expected a lot”
“Severe headaches – gone.”
I’ve been using Puresport electrolytes for around 3 weeks and the results have been incredible. I sweat a lot and suffer from severe headaches, yet since taking the electrolytes I haven’t had any!

“No issues with cramping.”
Took these for a few days before a local Hyrox Sim. Great taste and had no issues with cramping during the sim. Tasted a lot better than the other 3-letter brand I’d been using.

“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.

More Questions?
-
Yes, drinking electrolytes daily is safe. Electrolytes help maintain hydration, muscle function, and nerve signalling especially after regular intense running sessions or Hyrox workouts to help maintain peak performance.
-
Electrolyte powders like Puresport offer superior mineral content with zero added sugars, artificial colours, or preservatives compared to traditional sports drinks. Our concentrated formula provides more electrolytes per serving than typical sports drinks while being keto friendly, diabetic-safe, and calorie-free. You get better hydration without the sugar crash or empty calories.
-
Mix one Puresport sachet with 450ml to 900ml of cold water for optimal taste and electrolyte concentration. For stronger flavor or higher electrolyte needs during intense training, use 450ml water. For milder taste or sensitive stomachs, dilute with up to 900ml water. Always start with recommended ratios and adjust based on personal preference and activity level.
-
Yes! Electrolytes can significantly help with hangover recovery by addressing dehydration and mineral depletion caused by alcohol consumption. Puresport's balanced sodium, potassium, and magnesium formula helps restore fluid balance, reduce headaches, and combat fatigue. Take before bed after drinking and again upon waking for optimal hangover prevention and recovery support.
-
Both have benefits, but electrolyte supplements offer faster absorption and precise dosing when you need rapid rehydration. While foods like bananas (potassium) and salt (sodium) provide electrolytes, Puresport delivers optimal ratios instantly without excess calories or digestive delays. For pre/during/post-workout needs, Puresport supplements are more convenient and effective than food sources alone.
