What brain athletes are saying

Establish your foundation. Everything else follows.

The microplastic problem

The ingredients carry them. The packaging creates more.
Ki removed both.

94% of electrolyte brands contain microplastics.

Almost all electrolyte brands use single-use plastics, such as plastic sachets.

Removed from the ingredients. Refused in the packaging.

Founders Story

Zeus Kajita
Zeus Kajita Co-founder

Zeus was running on coffee and cortisol, quietly failing to show up at 100% for the people who mattered most. After discovering that sleep only got him to 70%, Ki closed the gap. His brain finally came online. The fog he had accepted as his personality was a substrate problem. Ki did not change his life. It gave him the energy to want to change it. ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎

“I had been skipping the second charge for so long, I had forgotten what 100% felt like. ki-founder-quoteki-founder-quote” — Zeus Kajita, Co-founder
Noa Fernando
Noa Fernando Co-founder

Noa spent two decades building businesses across luxury hospitality and manufacturing in Sri Lanka. She was running on depletion and calling it discipline. She met Zeus in Japan, started the Ki Hydration Rituals, and within weeks the chronic tiredness lifted. The sharpness she had attributed to good days became every day. She became the proof that it worked - and used that clarity to help build the brand.

“For the first time in years, I had the energy to want things again - and then the clarity to actually build them.” — Noa Fernando, Co-founder

Why can't I just drink more water?

Hydration isn't just availability - it's a transport problem. Without minerals, water passes through cells without being absorbed. You can drink three liters and still wake dehydrated. Minerals are the keys that let water into the cell.

What should I expect in my first week?

This is called the Recalibration Window. The first 48–72 hours can include mild adjustments as the body resets. By day five, most people notice the 3 pm wall is gone - energy, focus, and mood are more even through the day.

Why does Ki cost more than other electrolytes?

Most products sold as electrolytes are flavored sugar with a pinch of table salt. Ki is two whole-natural mineral salts, microplastic-removed at the source. The economics of building it cleanly are different - that's the whole product.

Can Ki be used during fasting?

Yes. Zero calories, zero sweeteners, zero flavoring agents - the protocol is designed to be taken on an empty stomach, which preserves a fasted state and supports electrolyte balance through the morning window.

Why is microplastic removal important?

Most commercially processed salts contain microplastics - sea salt especially. Ki uses a proprietary 0.5-micron filter at the source to remove them while preserving natural mineral balance.

Who is Ki for?

People whose work depends on sustained mental focus - operators, founders, clinicians, designers, knowledge workers. People who value clean inputs and intentional routines over flavored stimulation.

When does the Founders Batch ship?

July 06 2026, from our U.S. fulfillment center. Tracking is sent the day your bundle ships. Estimated delivery: 3–5 days domestic.

Can I use Ki every day?

Yes. Ki is designed as a daily hydration ritual, not a performance product. Consistency, not intensity, is the philosophy. One ritual, every morning.

Every morning you have been starting at 70%.

Every morning, you have been starting at 70%. Ki is the first hydration brand built to defeat dehydration before the day starts. Start every morning as the version of you that shows up at 100%.
