MORE THAN PRODUCTS - A LONG-TERM MOVEMENT LED BY ATHLETES, FOR ATHLETES.

Over the years, many brands that sponsor athletes have focused more on visibility than on actually helping them perform, sometimes even getting in the way of it.

We built Kaiju to do what most brands no longer do: focus on what athletes really need to train, push, recover, and start again. On the water, in the gym, and in everyday life. With products designed for real performance, not for marketing decks.

And we’re building it with athletes, not just for them. They test, challenge, and shape what we create. They’re part of the process, not just here to pose with our logo.

Kaiju is about supporting performance. Respecting it, fueling it, and standing alongside those who live it every day.

FAQ

What makes Kaiju Kick unique?

Kaiju Kick blends natural caffeine, electrolytes, and amino acids to deliver steady energy, full hydration, and long-lasting focus. While most energy drinks cause a spike and crash, Kaiju Kick keeps you alert without overstimulation.

Every ingredient is selected for purity, performance, and compatibility with high-level training.

How is Kaiju’s caffeine different?

Kick uses natural caffeine combined with L-theanine — an amino acid that smooths the caffeine curve. This synergy keeps you calm yet focused, avoiding jitters or heart-rate spikes.

You get sharp mental clarity and sustainable drive, even during long or intense sessions.

Can I combine Kaiju Kick with Kaiju Electrolytes?

Absolutely. They complement each other perfectly. Kaiju Electrolytes is ideal for pure hydration during long endurance sessions or hot conditions, while Kaiju Kick adds a cognitive and energy boost for high-intensity workouts, competitions, or long workdays.

Many athletes switch between them depending on their training needs.

When should I take Kaiju Kick?

It depends on your goal. For training or competition, start sipping about 30 minutes before to prime your system. During long sessions, you can drink it gradually to maintain focus and hydration.

Outside of sport, it’s great before a demanding work block, an early start, or travel days when you need sustained energy.

Will it make me jittery or cause a crash?

No — that’s exactly what Kaiju Kick prevents. The blend of caffeine, L-theanine, and L-tyrosine provides smooth, controlled stimulation without the sudden drop that follows sugary or synthetic energy drinks.

You’ll feel clear, steady energy that fades naturally without exhaustion.

Is Kaiju Kick safe for tested athletes?

Yes, completely. Kaiju Kick is manufactured in Germany under strict quality control, and every batch is tested under the Informed Sport certification program.

That means it’s screened for banned substances, ensuring total safety and trust for professional and Olympic athletes.
