It’s been a while since I updated my electrolyte drink mega-review, which was lacking in powder drinks. I’ve rectified that by adding 5 more drinks to the table: Endura Rehydration Low Carb Fuel, Endura Rehydration Performance Fuel, Hydralyte Sports Powder, Ultima Replenisher Electrolyte Powder, and my old favourite, Powerade Zero.
Endura Rehydration is a brand that’s been frequently recommended to me in the past, so I decided to do some investigation into its contents. At 22mmol/L of sodium, it’s on the low side – far less than Gastrolyte, Hydralyte and even Nuun tablets. Their low carb fuel contains minimal sugar content (1.66-3.74g/L), whereas the performance fuel has a lot of sugar – 60g! Don’t confuse them.
Hydralyte Sports Powder is a product I didn’t even know existed. Apparently there is a whole range of Hydralyte Sports products, but I focused on the powder in the tub. It has a higher sodium content than Hydralyte Ready to Drink and sachets (50mmol/L compared to 45), but slightly less than Hydralyte effervescent electrolyte tablets (60mmol/L). Unfortunately, it comes with a higher sugar content of 20g/L.
Ultima Replenisher is another new-to-me product, available on iHerb. It seemed promising – no sugar, very low cost – but I was let down by the very low sodium content (4.78mmol/L).
Powerade Zero is a product I always have lying around in the cupboard, but I never thought to review. It’s relatively expensive, but so convenient it almost makes up for the price tag. The 22mmol/L sodium content isn’t great, but a lot more than the sugary original Powerade Ion4 which has 12mmol/L.
I’ve also completely updated the table to add a cost per litre comparison. It’s hard to compare cost, as each product has its own specifications (such as how much water to mix with each serve). I’ve done my best to find a cost per litre, which will of course be out of date fairly quickly, but will hopefully serve as a handy baseline comparison.
Finally, a small errata – the table previously made no distinction between Hydralyte Ready To Drink, sachets and effervescent electrolyte tablets. This was wrong, as the tablets have a higher sodium content (60mmol/L compared to 45mmol/L). The table has been updated to reflect this.

Great information! I need to get better about this. Still trying to eat more iron, once I get that routine down I’m going to work on making these drinks habitual!

It’s hard to implement these changes when you struggle with everyday things. I hope you manage to incorporate electrolyte drinks in your diet and most importantly that they make a difference to you!
