Soy Isolate is a plant-based protein with up to 87 % protein and an amino acid profile similar to that of whey protein. A 30 g serving provides up to 26 g protein and a full spectrum of essential amino acids. The raw material has a declared solubility of at least 88 % and is derived from non-GMO soybeans. The product is packaged in Germany in a facility that meets IFS, ISO and HACCP standards and each flavour is tested in an accredited laboratory for heavy metals and microbiological purity.
Soy Protein Isolate is the most concentrated plant-based protein in our range. Depending on the flavour, it contains up to 87 g of protein per 100 g, so a single 30g serving provides up to 26 g of protein. This helps support the growth and maintenance of muscle mass.
It is also fat-free and low in sugars. One serving contains just around 110 kcal, ideal when you're trying to lose weight and every calorie counts. It contains no gluten, lactose or milk protein and is suitable for vegans.
Made from soy that has not been genetically modified
The isolate is made exclusively from non-genetically modified soybeans. Much of the world's soy production is genetically modified, so this cannot be taken for granted, and the manufacturer confirms it for every batch.
The raw material has a declared protein content of at least 90 % on a dry matter basis, with no more than 0,5 % fat and no more than 0,5 % fibre. The grinding fineness is specified as 100 mesh, at least 95 %, so the powder does not form lumps. The pH of the aqueous solution stays between 6,5 and 7,5, within the neutral range.
Plant-based proteins have one weakness compared with milk proteins. Almost all of them lack an essential amino acid, meaning one that the body cannot produce on its own. Pea protein, for example, lacks methionine, while rice protein lacks lysine. As a result, the body can only use part of the protein it takes in.
Soy Protein Isolate does not have this gap. It contains all nine essential amino acids in sufficient amounts, setting it apart from other plant-based proteins.
This is also confirmed by a scientific assessment of protein quality. The PDCAAS score combines amino acid composition and digestibility into a single number from zero to one. Soy Protein Isolate achieves a score of 1,00,1 the same as whey protein, casein or egg white. Pea protein scores around 0,9, while rice protein scores lower.
A serving of 30 g therefore provides 9,3 g of essential amino acids, including 4,65 g of BCAA. The most abundant is leucine at 8,1 %, the amino acid most frequently studied in relation to muscle growth.
Plant-based proteins have a reputation for being hard to mix and staying grainy. With soy isolate, this can be measured.
The specification states a nitrogen solubility index (NSI) of at least 88 %. This laboratory parameter indicates how much of the protein actually dissolves in water. This is a high value for plant-based proteins, and you will notice the difference in your shaker, as it mixes easily without lumps or sediment at the bottom.
This makes the isolate suitable for more than just drinks. You can also add it to porridge, smoothies or pancake batter without changing the texture of your food.
Soy Protein Isolate is finished and packed in Germany, at a facility that meets IFS, ISO and HACCP standards.
We then have the finished product independently tested. Each flavour is checked by German laboratories accredited to DIN EN ISO/IEC 17025 and registered with DAkkS. Tests check levels of lead, cadmium and mercury and microbiological purity, covering yeasts, moulds, coliform bacteria and salmonella.
In all tested batches, heavy metal levels were well below the legal limits, and the laboratories confirmed compliance with Regulation (EU) 2023/915, which sets maximum levels for contaminants in food.
The full reports are openly available in the Laboratory Tests section on the product page.
Who is Soy Protein Isolate for?

Flavor: chocolateI don’t understand what you keep making a fuss about, taste… when you want taste, then take curd, meat, soy—whatever you like. I take the protein to supplement the protein I don’t get in my diet. I come read reviews and it’s all just crap about how it tastes. It doesn’t interest me how it tastes! What interests me are its nutritional values and whether I’m going to get sick from it!
