The 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
In a typical conventional protein bar — isolates, syrups, binders.
Syrups
Do the work of making isolated proteins palatable.
Palm
Used as cheap filler fat, not as food.
The gap
Clean — but hard to love.
Tasty — but far too sweet.
Where we stand
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.
Clean label & low sugar vs. taste

Protein-fat bars combining bone marrow fat with beef bone protein. No seed oils. Thoughtful recipes, with every ingredient in plain sight.
Bone marrow, bone broth and fruit. No added sweetener at all — our proof of concept. 6 real ingredients, 4 of them organic.

Made. Tasted. Made again.
Bone marrow in a bar? It shouldn't taste this good. Tens of recipe iterations and multiple tastings later, we're turning that expectation on its head.
Our ambition: the pleasure of a dessert from a Michelin-starred kitchen, made with ingredients that hide nothing. We kept making, tasting and refining until our chef was happy.
Philosophy
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 sweeteners, colours or synthetic preservatives either. Not in any product, not in any batch.
Bone marrow fat and beef bone protein lead every label — the foods humans were built on.
Traceable farms, pasture-raised livestock, from pasture to wrapper. Where something can't be organic yet, we say so.
Small batches, no deodorisation, no chemical refining. Made the way a good kitchen makes food.
Every recipe is signed off by Liutauras, a chef from Michelin-level kitchens. Would a chef serve it? If not, it doesn't ship.
Built by two fathers for their own kids' lunchboxes — calm, honest food, not a diet-tribe badge.

Progress
Oct 2
We announced a new kind of bar on LinkedIn: beef bone marrow and bone broth in a bar.
See the LinkedIn postOct 17
We pitched EARTHIST on Shark Tank Lithuania. The result is still a secret.

From the lab to real machinery. The flavour is great; the texture needs adjusting.
Nov 2
We're taking a little more time: launch moves to the end of November. The flavour is there; the texture is getting the attention it needs.
Why fats
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.
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.
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.
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.
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.
Where it comes from
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.
Grass-fed, free-range, organic cattle from Sweden — the marrow, broth and collagen come from farms we know by name.
Ghee, honey, cocoa, fruit, salt and spices — every one of them traceable to its source.
Produced in Lithuania to our own recipe and under one of the EU's strictest food-control regimes.
No black boxes. We know where every gram in your bar came from, and we can tell you.
