BLG protein explained
What you should know about BLG.
Before we dive into Beta-Lactoglobulin (BLG), the protein used in TWOZERO®, let's first cover the basics.
What is exactly a protein?
Protein is one of the body's most important components. It helps build and repair muscles, skin and other tissues, and supports the production of enzymes and hormones that keep your body functioning properly. You can get protein from everyday foods like meat, fish and dairy, but also from protein supplements such as whey or pea.
What is protein made of?
Proteins are made up of amino acids, there are 20 different amino acids. Each amino acid plays a unique role in the body: some stimulate muscle protein synthesis — the key process for building new muscle tissue — while others support energy production during exercise or help regulate blood sugar. Amino acids are grouped into two categories: essential and non-essential.
Essential amino acids
These 9 amino acids cannot be produced by your body and must come from food or supplements.
Amino acids: Lysine, Methionine, Threonine, Phenylalanine, Tryptophan, Histidine, Leucine*, Isoleucine*, Valine*
Non-essential amino acids
These 11 amino acids are produced naturally by the body and therefore are not required from diet.
Amino acids: Alanine, Glutamic, Glycine, Asparagine, Serine, Proline, Glutamine, Arginine, Glutamine, Cysteine, Tyrosine, Aspartic acid
* These are branched-chain amino acids (BCAAs), a special subset of EAAs that play a key role in muscle recovery and growth.
Whey as golden standard
Whey protein is the most used and trusted protein supplement worldwide. This is because whey protein has a complete amino acid profile and, unlike other proteins, contains a high amount of essential amino acids.
What is a complete amino acid profile?
A protein source is called complete when it contains all 9 essential amino acids in sufficient amounts. While whey is a complete protein, many plant-based protein supplements, such as pea protein, are not.
Whey is not just one protein
Unlike what many people think, whey protein is not a single protein. It is actually a blend of several proteins, known as protein fractions.
Each fraction has a unique amino acid profile, which means that the proportion of individual amino acids — essential and non-essential — differs between fractions.
While standard whey contains a mix of protein fractions, TWOZERO® uses only Beta-Lactoglobulin (BLG).
BETA-LACTOGLOBULIN ±55%
ALPHA-LACTALBUMIN ±20%
Glycomacropeptide ±10%
Others ±10%
Immunoglobulins ±5%
Protein fractions
Whey more powerful
The reason we focus on this single protein fraction is simple: BLG stands out with its unmatched amino acid profile. It contains far more essential amino acids and BCAAs than any other protein fraction. By isolating BLG, whey protein reaches its purest and most potent form: pure BLG.
When comparing BLG to standard whey, this is how the amino acid profiles differ:

Leucine
% of total protein
What is leucine?
Leucine is one of the BCAAs and plays a key role in kickstarting muscle protein synthesis (MPS), the body's process for repairing and building muscle after exercise. It is the most important amino acid for optimal muscle recovery and growth.
45% more leucine than standard whey
Traditional whey protein typically contains around 10.9% leucine. By comparison, BLG contains 15.8% leucine by weight, providing 45% more leucine per gram of protein.
This results in 3.2g of leucine per can of TWOZERO®, whereas a traditional protein shake with 20g of standard whey provides only 2.2g of leucine.
This matters because scientific studies show that about 3 grams of leucine are required to maximally stimulate muscle protein synthesis (MPS). If this threshold is not reached within a 1–2 hour window after consuming protein, MPS is only partially activated or may not be activated at all.

Leucine content (g)
Why is the leucine threshold so important?
Leucine acts as the on-switch for muscle growth. Only when there is enough leucine in your blood — so when the leucine threshold is met — does your body receive the signal to activate muscle protein synthesis (MPS). This is the process where your body repairs and builds muscle.
A daily routine.

It literally tastes like a refreshing drink. Not like a supplement, not like something you force down — just clean, light, and sparkling. I forget there's 20g of protein in it.
