Our story · since 2024

The body hasn't changed. Everything around it has.

We eat better than our grandparents. We train harder, sleep more, track everything — and still feel depleted by Wednesday.

One ordinary day — routes of contact

  1. 07:10

    The shower

    Heated water and steam in a room full of synthetic surfaces and fabric.

    DermalInhalation
  2. 07:40

    The first coffee

    Plastic kettle components, a lined takeaway cup, near-boiling water.

    Ingestion
  3. 08:25

    The commute

    Tyre and brake wear is one of the largest sources of airborne particulate in cities.

    Inhalation
  4. 12:30

    Lunch, reheated

    Heat plus a container. The most studied everyday transfer route there is.

    Ingestion
  5. 14:05

    The receipt

    Thermal paper. Held for four seconds, absorbed through the skin.

    Dermal
  6. 18:45

    A glass of water

    Tap or bottled, both carry a measurable particle load. Bottled carries more.

    Ingestion
  7. 22:30

    Clean sheets

    Synthetic fibres shed continuously through washing, drying and eight hours of sleep.

Not one of these is a mistake anyone made. That was the part we couldn't get past.

Ch. 02 The shelf

So we went looking for something to take. It was worse than we expected.

Hundreds of products. Almost none that would tell us what was actually in them, at what dose, verified by whom.

Field note Every label made a claim. Almost none published the evidence behind it.
  1. 01

    Proprietary blends

    A list of ingredients with no doses attached. You can't evaluate what you can't see.

  2. 02

    Particle size unmentioned

    With zeolite, surface area is the mechanism. Most labels never name the number.

  3. 03

    Testing claimed, not shown

    "Third-party tested" printed on the box. The certificate on request, or never.

  4. 04

    Certainty for sale

    Promises stated far past what the research actually supports.

Zeolite cage structure

So we stopped shopping. We started sourcing.

Ch. 03 The people

Three of us, asking the same thing. None of us could answer it.

We're young. We train, we eat well, we sleep. By every measure we should feel incredible — and we didn't. Harmonex exists because of that gap.

Ch. 04 What's next

We'd rather be slow than loud. Two formulations, for now.

There's no roadmap on a whiteboard here. There's a standard, and a third product only arrives when it meets it.

  1. 01

    Every dose stays on the label

    No proprietary blends. If it's in the formula, the number is printed.

  2. 02

    Every batch gets published

    Third-party results available without asking, not on request.

  3. 03

    We say only what the research says

    Supported function, not mechanism sold as certainty.

These are the rules we'd want followed if we were the ones buying.

Ch. 05 Where it landed

Live cleaner. Think sharper.

Everything above, in two bottles. One handles what comes in. One supports the cells doing the work.

Every batch third-party tested. Certificates published, not on request. Read the studies →
