The problem

The protein bar aisle has a sugar problem.

Pick up a typical protein bar and turn it over. Behind the big protein number on the front, the back label tells a different story.

15–30

ingredients

In a typical conventional protein bar — isolates, syrups, binders.

Syrups

& sugar alcohols

Do the work of making isolated proteins palatable.

Palm

& seed oils

Used as cheap filler fat, not as food.

The gap

Label readers get two bad choices.

Pemmican & jerky bars

Clean — but hard to love.

  • Dry, chewy, gamey meat and fat
  • Eaten out of discipline, not pleasure
  • Skulls-and-fire branding that scares off families

Sweet “carnivore” & protein bars

Tasty — but far too sweet.

  • Honey, dates or syrups carry the flavour
  • Sugar and carbs creep up fast
  • Label readers notice — and walk away

Where we stand

We own the sweet fat spot.

Pemmican-level fat and carbs. The taste of a real bar. Our PURE bar carries 8 g of fat and 9 g of protein with under 1 g of carbs — and no added sweetener at all.

Bone marrow fat and beef bone protein do the heavy lifting, so the label stays short and the bar still tastes like food, not fuel.

Philosophy

Food that hides nothing.

Short labels, open sourcing, honest claims. What we refuse to compromise on is not a marketing line — it's the standard every batch is held to.

No seed oils. Ever.

No sweeteners, colours or synthetic preservatives either. Not in any product, not in any batch.

Animal fat and protein first

Bone marrow fat and beef bone protein lead every label — the foods humans were built on.

Certified organic, short chain

Traceable farms, pasture-raised livestock, from pasture to wrapper. Where something can't be organic yet, we say so.

Minimal processing

Small batches, no deodorisation, no chemical refining. Made the way a good kitchen makes food.

Chef-made

Every recipe is signed off by Liutauras, a chef from Michelin-level kitchens. Would a chef serve it? If not, it doesn't ship.

For the family

Built by two fathers for their own kids' lunchboxes — calm, honest food, not a diet-tribe badge.

A team that has done this before.

Why fats

We didn’t become human despite fat. We became human because of it.

Two million years ago we were apes with small brains. Then we learned to crack a bone open and eat the marrow inside — the densest, most dependable fuel on the savannah. That fat paid for the brain that eventually became us.

Two early human ancestors crouched on dry ground, cracking a bone open to eat the marrow
01

It started with marrow

Apes that could get at bone marrow ate better, thought better and survived better. The road from ape to Homo sapiens was paved with fat.

02

The first protein bar

Indigenous peoples of North America dried meat, pounded it with rendered fat and carried it for weeks. Pemmican was the original protein bar — real fuel, and it tasted like survival.

03

Fat ran the kitchen

The first French fries were fried in tallow. Soap was boiled from lard. Butter, ghee and marrow were the everyday fats of every kitchen on earth.

04

Then we were told to fear it

Refined oils and low-fat dieting moved in, and the longest-lasting fuel we ever had was renamed the enemy. No chef, no farmer and no grandmother ever agreed with that.

We think that’s a mistake worth fixing. So we’re bringing fat back.

Organic grass-fed cattle grazing in a Swedish pasture

Where it comes from

In control from farm to bar.

No black boxes. Our cattle are Swedish Organic, grass-fed and free-range, and the marrow, broth and collagen in every bar come from farms we know by name.

Everything else is certified organic too, and every batch is traceable back to the farm it started on. If something can’t be organic yet, we say so.

01

Swedish Organic cattle

Grass-fed, free-range, organic cattle from Sweden — the marrow, broth and collagen come from farms we know by name.

02

Certified organic, all the rest

Ghee, honey, cocoa, fruit, salt and spices — every one of them traceable to its source.

03

Made to our spec

Produced in Lithuania to our own recipe and under one of the EU's strictest food-control regimes.

04

Traceable, batch by batch

No black boxes. We know where every gram in your bar came from, and we can tell you.
