The future of protein
Not whey. Not plant. Smarter.
A next-generation protein grown through fermentation. Complete, high in BCAA, and absorbed like whey, with zero lactose and a fraction of the footprint.
Complete aminos
23%+ BCAA
0g lactose
Vegan
What is Smartein
A complete protein, grown not farmed.
SMARTEIN is made by fermenting natural sugars with yeast, the same process behind bread, beer and yogurt. The result is over 80% pure protein with everything your body needs and nothing it does not.
80%+pure protein
23%+BCAA
1.0PDCAAS, like whey
The best of both worlds.
Whey is complete but comes from milk. Plant protein is clean but often incomplete. SMARTEIN is a third path: complete like whey, clean like plant, made by fermentation.
Like whey
Complete & absorbable
A full amino acid profile with high BCAA and a PDCAAS score of 1.0, so it is absorbed as efficiently as whey protein.
Like plant
Clean & vegan
100% plant-fermented and vegan, with zero lactose, casein, gluten, soy, GMO or added sugar.
Only Smartein
Grown by fermentation
Protein from Saccharomyces cerevisiae yeast, grown on natural sugars without farms, herds or heavy resource use.

Comparison reflects SMARTEIN's verified profile (over 80% protein, over 23% BCAA, PDCAAS 1.0, allergen-free) against typical whey and plant proteins. Individual plant blends vary.
How it's made.
No farms. No herds. Just fermentation, the oldest food technology there is.
⚗︎ The same process behind bread, beer & yogurtNatural sugars
We start with renewable plant sugars from molasses, sugar cane and sugar beet.
Fermentation
Saccharomyces cerevisiae yeast feeds on the sugars and multiplies, exactly as it does in a brewery.
Pure protein
The yeast builds a complete protein, which we gently separate, filter and dry to over 80% purity.
Clean powder
What is left is protein with all the aminos and BCAAs, and none of the lactose, sugar or allergens.

Why Smartein.
Six reasons a fermented protein beats the tub you are using now.
80%+
Serious protein
Over 80% pure protein per serving, so a single scoop does real work.
9/9
Complete amino profile
Every essential amino acid your body cannot make on its own, in one source.
23%+
High BCAA
Leucine, isoleucine and valine make up over 23% of the protein, the aminos that drive recovery.
1.0
Whey-level absorption
A PDCAAS score of 1.0 means it is used as efficiently as whey, while digesting slower for lasting fullness.
0g
Lactose, sugar & allergens
Free from lactose, casein, gluten, soy, GMO and added sugar. Vegan and easy on the stomach.
+
Naturally enriched
Beta-glucans and B vitamins come built in, with vitamin D and B12 added in chocolate and cookie.
Cleaner protein, clearer proof.
The numbers behind the claims. Over 80% protein, a complete amino profile, and absorption that matches whey.
Protein first, nothing noisy.
Protein leads the nutrition profile, with the supporting macros kept clear and easy to compare.

Approved & endorsed
Registered with the Serbian Ministry of Health and reviewed by Prof. Damjan Vučurović, Biotechnology, University of Novi Sad.
Built on BCAAs.
Protein the planet can afford.
Conventional protein leans on herds, farmland and water. Fermentation does not. SMARTEIN is grown in a controlled process that sidesteps the heaviest costs of dairy and crops.
🌱
No farmland
Grown by fermentation, so it needs no large cultivation areas or grazing land.
💧
Spares water
The process is built to avoid the heavy water demand of dairy and crop protein.
🌍
Lower emissions
No herds and no field agriculture means far less greenhouse-gas pressure.

What is Smartein?
SMARTEIN is a next-generation protein grown through fermentation rather than farmed from animals or crops. Yeast (Saccharomyces cerevisiae) is fed natural plant sugars and produces a complete protein that is over 80% pure, with a full amino profile and over 23% BCAA. It is not whey and not plant protein, it is a new category.
How is it different from whey or plant protein?
It combines the strengths of both. Like whey it is a complete, highly absorbable protein (PDCAAS 1.0). Like plant protein it is 100% vegan and free from lactose. Unlike either, it is grown by fermentation with a much lighter environmental footprint.
Is it really a complete protein?
Yes. SMARTEIN contains all the essential amino acids your body cannot produce on its own, including high levels of the three BCAAs (leucine, isoleucine and valine) that support muscle recovery.
Is it vegan and free from allergens?
Yes. SMARTEIN is vegan and free from lactose, casein, gluten, soy, GMO and added sugar, which makes it suitable for people who do not tolerate dairy or gluten well.
Why is fermentation more sustainable?
Because the protein is grown in a controlled process, it needs no farmland or herds, spares water, and produces far fewer emissions and no waste, all while being independent of weather and climate.
How do I use it?
Mix one 30g scoop with 250-300ml of water or your drink of choice, one to three times a day. It works in shakes, oats, smoothies, baking and recipes thanks to its clean, neutral base.
