My first time trying Kaiju electrolytes…

My first time trying Kaiju electrolytes and I love the flavour and great that it’s athlete friendly. I really like the waterbottle too - lightweight and easy to carry around. I also prefer how they are in sachets. Keeps me hydrated throughout my sessions!

Couldn’t stomach the taste

Ordering and delivery was good, but I just couldn’t stomach the taste of the product. I’m used to the LMNT brand of electrolytes but willing to try something different. Sad to report that the Kaiju electrolytes just did not agree with me.

Things that I love

Things that I love, packaging is easy to use just pick up a sachet and go not having to bring tubs or tablets to dissolve. Then the fact it is dissolved basically instantly instead of having to wait 15 minutes.

Kick again I was extremely impressive with. The ingredient I usually take separately for brain function so to have it in one drink was unreal. And to have something which wasn’t crazy amounts of caffeine but just a little pick up between session was so refreshing.

Team GB Boxer 5* review

As a Team GB boxer hydration is paramount for performance . Kaiju electrolytes are a stand out for me in the electrolyte market. Great tasting and an overall great product. The individual sachets are a great idea instead of tablets to keep fresh.

Great Product

Was recommended to try Kaiju by my PT and initial impressions are that it is a fantastic product.

Brilliant blend of ingredients to give an overall boost throughout the day and for training (kick) and then the electrolytes work very well sustaining performance and helping recovery.

Also… they taste fantastic!

I’ve tried quite a few electrolyte…

I’ve tried quite a few electrolyte brands over the years, but Kaiju genuinely surprised me. The taste is easily one of the best I’ve had — really refreshing without being overly sweet or artificial. It actually makes staying hydrated enjoyable rather than feeling like you’re forcing down a supplement.

What impressed me even more is how effective it’s been. Since using Kaiju, it’s genuinely upped my HYROX training and running game. I feel better hydrated during sessions, my energy levels are more consistent, and recovery after tough workouts feels noticeably better.

Overall the experience has been unbelievable. Great taste, clear effectiveness, and something that’s now part of my regular training routine. I’d highly recommend it to anyone serious about their training or endurance sports.

Amazing product

Amazing product; clearly had more thought and research put into it than other sports drinks, and this shows in its efficacy. Highly recommend
