I tested both products (+ the bottle) and honestly, I was very pleasantly surprised.
Having tried quite a few products in this category, I’d say this is clearly one of the best.

I use them for my tennis training sessions and matches, and the difference is noticeable.
Usually, these kinds of drinks are too sweet, with an overly sugary taste (even when there’s no actual sugar), not hydrating enough, and sometimes they even make you thirstier.
Here, it’s the complete opposite: easy to drink and genuinely effective.

As for Kick, the effect is there but very smooth. No uncomfortable sensations, just the right amount to stay focused and perform on court.

Overall, really great products — highly recommend 👌

Not only does Kaiju taste amazing, it actually makes a difference during and after workouts. It’s clean, refreshing and effective – definitely a 5 star go to for training and busy days.

Clean hydration that actually works

I’ve really enjoyed using Kaiju over the last few weeks. It genuinely makes a difference in how I feel, whether I’m training or just out in the heat. I love what the brand stands for – clean, transparent ingredients with no added junk. It’s clear this product was built by athletes, for performance, and it’s helped keep me hydrated even when I’m not in peak athletic mode. It’s very effective and I’m happy to recommend it to anyone who needs reliable hydration.

I love Kaiju

I love Kaiju. I do lots of hot yoga and know I lose a fair amount of fluid. I will drink 750ml during any class. Knowing I can replenish with Kaiju afterwards makes such a difference. It’s just become part of my self care routine. (Love the flavours!)

The Kaiju electrolyte powder was awesome, tasted great and really handy in the small sachets, so you could tuck one or two in a pocket and top up your water bottle on a long bike ride. Or keep them handily in a work bag. Highly recommend!

Really like the flavour of kaiju and it doesnt have the artificial aftertaste that ive found most electrolytes have, especially the tablet products. Another big plus for me is that it doesnt fizz up like the tablets do so your bottle doesnt try to explode on the bike and its much easier to get down whilst exercising

Healthy & field-proven products

They deliver products targeted to healthy performance, for professional athletes and demanding sports enthusiasts like me.
It’s reassuring to know that a nutritionist and elite athletes are part of the Kaiju team.

I love Kaiju.

I love Kaiju.
It’s one of the best sports drinks I’ve tried (and I tried many), not too sweet and gentle on the stomach during workouts.
I use it for my daily training and long runs and it really makes a difference.

Best tasting electrolytes I’ve had

The delivery came really quickly and honestly these are the best tasting electrolytes I’ve had - I look forward to having them every morning! Great if you are looking for something not too sweet, that doesn’t taste artificial. The kick also never fails to get me through tougher days, or days when I just can’t focus, without making me feel anxious or crash later on. Can’t recommend enough.
