Protein + Fat Bars / Launching soon
The fat that made us human.
For two million years, animal fat was one of the most valued foods we had. But the food industry convinced us to fear animal fats. EARTHIST is built on the longer history — bars of bone marrow fat and beef bone protein, with nothing hidden.
Be first to know when the bars ship. No spam, ever.
The founders
Business instinct. A chef's palate. One shared table.
Arūnas spent fifteen years building organic food brands — bean-to-bar chocolate, raw dog food, organ supplements. Liutauras spent his in Michelin-level kitchens, learning what makes flavour honest. When Liutauras's own health led him to meat, organs and animal fats, he noticed the shelves were built on the opposite: seed oils, sugars, starches.
Together they kept coming back to one question: why have the cleanest foods humans ever ate almost disappeared? And a second, more personal one — as parents: what will our kids grab when they're hungry and we're not there?
Liutauras Čeprackas
Co-founder / Product leadA chef with experience in Michelin-level kitchens. He develops the recipes, selects ingredients and shapes the flavour of every bar.
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.
The first range
Three bars. Ingredients you can read.
Protein-fat bars combining bone marrow fat with beef bone protein. No seed oils. Thoughtful recipes, with every ingredient in plain sight.
