— A Clean Body · A Clean Planet —

Crafted in Japan · The Second Charge

Built the slow way.

Crafted slowly, cleanly, and with the planet in mind.

A morning hydration ritual that took longer to make — because anything cleaner takes longer. Purity in the ingredients, restraint in the sourcing, simplicity in the form.

Ki refused all of it.

The result took longer to build, costs more to make, and is cleaner in every way that matters.

Before the day begins The two-step morning ritual

The body restores 70% overnight. Ki closes the remaining 30%.

The long way

There is a fast way to make electrolytes. Ki took the long way.

The wellness industry chose quicker. Fillers that extend the powder. Sweeteners that sell more easily. Salts bought without question because contamination doesn’t show on a label.

Ki refused all of it.

The result took longer to build, costs more to make, and is cleaner in every way that matters.

The fast path

What the category did

Quicker. Cheaper. More profitable.

Bulk-buy commercial salt. 94% contains microplastics. Nobody asks.

Add four to eight ingredients — fillers, flavors, sweeteners. 3 to 6 grams per serving.

Pack into multilayer plastic sachets. Cheap, light, unrecyclable.

Tear-open format. Disposable, single-use, designed to be thrown away.

Sell convenience. Move volume. Externalise the consequences.

The slow path

What Ki did instead

Longer. Costlier. Cleaner.

Source two whole mineral salts directly from the Sea of Japan and ancient European deposits.

Engineer a proprietary 0.5-micron microplastic removal process at the Tsushima Island facility.

Reject every additive. Two ingredients. 1.5 grams per serving. Nothing the body doesn't need.

Develop a paper cylinder with a metal lid. Zero plastic. Compostable at end of life.

Build the ritual around the home, not the gym bag. Convenience from consistency, not portability.

Two ingredients. Two steps. Two minutes. Not because simplicity was easy — because simplicity is the Japanese standard for something designed to last.

Responsible sourcing

Two ingredients. Real ingredients.

Most electrolyte brands use processed ingredients such as table salt. Ki uses none of it. ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ Marine minerals from the Sea of Japan.

The microplastic crisis

The category has a four-part microplastic crisis. Ki addresses all four.

Most brands address none. A few address one. Ki is the first to address all four simultaneously — because addressing only some of them is not actually addressing the problem. The contamination enters through ingredients, leaches in through packaging, fragments in at the moment of opening, and lingers in the environment for decades. A real fix has to interrupt every vector.

0.5μ

The threshold Ki removes microplastics down to.

Contaminated ingredients

Category default

94% of commercial salts contain microplastics. Average load is 140 particles per kilogram. The premium "clean" option — Himalayan pink — tested highest of any salt at 174 particles per kilogram.

Ki's answer

A proprietary removal process at a 0.5-micron detection threshold — 10,000× more precise than the 5mm boundary used in most published research. Both Ki ingredients pass through it.

Zero

Polymer surfaces between the powder and the drink.

Leaching sachet lining

Category default

The polymer film that lines every standard sachet leaches microparticles directly into the drink — every serving, every morning.

Ki's answer

No polymer lining anywhere in the system. The paper cylinder contains the powder; a wooden spoon delivers it. The drink touches paper, wood, and water. Nothing else.

Tear events per serving.

Tear fragments at the point of use

Category default

Shearing through a multilayer plastic sachet releases 0.46 to 250 microplastic particles per centimetre of cut (Fang et al., 2020). The last act before drinking introduces a fresh dose.

Ki's answer

Nothing to tear. The cylinder opens, the spoon scoops. No shearing, no fragments, no contamination at the moment of consumption.

730→12

Single-use units per year.

730 sachets to landfill, per customer, per year

Category default

At two servings per day, a committed user would generate 730 single-use sachets per year — all to landfill. Every one a future source of microplastic fragmentation as UV, abrasion, and microbes break the polymers down over decades.

Ki's answer

One paper cylinder per month. Twelve per year. 97% less single-use packaging waste, by unit count, than the sachet alternative.

The 97% figure refers specifically to single-use packaging unit count (1 cylinder/month vs. 30 sachets/month). It is a Ki-derived calculation, not a published lifecycle analysis. A full LCA would be required to compare total carbon footprint or material weight.

The microplastic crisis

The product category built to support your health has been quietly undermining it. Ki is the correction.

The category has a four-part microplastic crisis. Ki addresses all four through a proprietary filtration process at our factory in Tsushima Island, Japan. No other electrolyte brand operates at this level.

The packaging

One cylinder. Sixty servings. No sachet.

Ki ships a new paper cylinder with a metal lid and a wooden spoon every month. Each cylinder holds sixty servings — a thirty-day supply at the recommended two-serving protocol. The cylinder is paper, contains zero plastic, and composts at end of life.

One cylinder a month replaces thirty single-use sachets a month. Twelve a year replaces seven hundred and thirty. A product engineered with microplastic-removed ingredients cannot be delivered inside packaging that creates them.

The format follows the ritual

The sachet exists because the category was built to be carried. Ki was not.

Most electrolytes are designed for the gym bag, the airport, the desk drawer — single-serve, tear-open, dose-on-the-go. That use case created the sachet, and the sachet created the packaging problem.

Ki is the second charge: a two-step morning ritual completed at home in the first hour of waking. The cylinder lives on the counter. The convenience single-serve packaging exists to provide is convenience the product does not need.

The sachet logic

One serving, sealed for portability, designed to survive a backpack. The format optimises for the moment of consumption being unpredictable — anywhere, anytime. The cost of that optimisation is paid in plastic, every serving, every day, by every customer.

The Ki logic

The moment of consumption is the same every morning, with the Ki Ritual Glass Bottle. There is no daily portability problem to solve. The cylinder lives on the counter at home and travels in the carry-on on the road. Either way — no torn sachet, no multilayer plastic, no waste.

Step 01 · Upon waking

16oz

Room-temperature water with one serving of Ki, mixed in the Ki Ritual Glass Bottle, on an empty stomach. The body has reached 70% overnight. This is where the second charge begins.

Step 02 · 45 minutes later

16oz

A second 16oz with Ki as the first serving absorbs. The remaining 30% restored. The body arrives at 100% before the day begins.

Step 03 · The day begins

0 sachets

The cylinder returns to its place. Nothing torn open, nothing thrown away. On travel days, the cylinder moves with you. The ritual moves with you.

THE MICROPLASTIC STANDARD

94% of electrolyte brands contain microplastics. Ki removed them.

A clean ingredient is not clean if it carries plastic into your body.

Crafted in Japan. Japanese standards. No other electrolyte brand operates at this level.

THE FILTRATION

The industry tests at 5mm. Ki filters at 0.5 microns. 10,000 times stricter.

THE PROTECTION

Removed from the ingredients. Refused in the packaging.

The making

Electrolyte Sachets create microplastics.

The electrolyte category runs on single-use plastic. Sachets, sticks, individually wrapped doses. Designed to be torn open and thrown away. Convenient for the customer. Profitable for the brand. Devastating for the planet.

Ki refused the format.

A single Ki cylinder replaces 60 sachets per month. Paper cylinder. Metal lid. Glass bottle for the daily ritual. No single-use plastic.

The packaging is held to the same standard as the formula.

The numbers

A year on Ki versus a year on sachets.

For a customer following the recommended two-servings-a-day protocol, here is what the year looks like — across every vector that matters.

Metric	A year on sachets	A year on Ki
Single-use packaging units per year	730 Multilayer plastic, single-use	12 Paper cylinders, refilled monthly
Material at end of life	Multilayer plastic laminate — effectively non-recyclable	Paper cylinder with metal lid — no laminate
Microplastic exposure from packaging contact	Polymer-lined inner surface, in direct contact with powder daily	None — paper and wood only
Microplastic fragments at point of opening	0.46 to 250 particles per cm of tear (Fang et al., 2020)	None — nothing to tear
Microplastic load in source ingredient	Up to 174 particles/kg (Himalayan pink, J. Env. Science, 2022)	Removed to 0.5 micron
End-of-life	Landfill, indefinitely	Compostable

Every sip, less plastic

Every morning, the second charge.

Sleep gets you to 70%. Ki closes the gap. Momentum is Ki.
