Soy Isolate – plant-based protein with up to 87 % protein and laboratory-verified purity

Soy 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 muscle growth and maintenance.

It is also fat-free and low in sugars. Each serving provides just around 110 kcal, which is ideal when losing weight and every calorie counts. It contains no gluten, lactose or milk protein and is suitable for vegans.

Made from non-genetically modified soy

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 content of at least 90 % protein on a dry matter basis, no more than 0,5 % fat and no more than 0,5 % fibre. The specified grind size is 100 mesh, minimum 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.

Soy Isolate – plant-based protein with up to 87 % protein and laboratory-verified purity
Plant-based protein that matches whey protein

Plant proteins have one drawback compared to dairy proteins. Almost all of them lack an essential amino acid, 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 consumed.

Soy isolate has no such gap. It contains all nine essential amino acids in sufficient amounts, setting it apart from other plant proteins.

This is also confirmed by scientific assessments of protein quality. The PDCAAS score combines amino acid composition and digestibility into a single number from zero to one. Soy 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 30 g serving 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.

Mixes without lumps, even in a basic shaker

Plant-based proteins have a reputation for being difficult to mix and leaving a grainy texture. With soy isolate, mixability 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 a plant-based protein, and you will notice the difference in your shaker: 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.

We test each flavour separately, not just one batch

Soy isolate is finished and packaged 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. Testing covers levels of lead, cadmium and mercury as well as microbiological purity, checking for yeasts, moulds, coliform bacteria and salmonella.

In all tested batches, heavy metal levels were well below 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.

Don't buy it because both the vanilla and the chocolate flavor are awful! If, for some reason, you still decide to buy it, I advise you to mix it with banana, strawberry, and kiwi—also acceptable.

    The vanilla scent is only barely tolerable for me; it melts just fine at first, and then it turns into some kind of slime. I hope I can last until it’s finished, but definitely I will never order it again.

    Flavor: chocolate, vanilla
    The price is very good, but the vanilla flavor is disastrous— it would be best if there were an option for unsweetened and unsavory/not sweet, so it could be used in savory recipes as well and so it wouldn’t ruin the sweet ones with the sweetener. The chocolate flavor is much better, but the sweetener isn’t to my taste.

    I would say the product is quite good; it mixes perfectly with water/milk! You know, plant proteins are fundamentally different from dairy and animal proteins on the market. Yes, many people may not like it, because it does not have enough sweetness compared to other types that are sold. Without a doubt, the price-to-quality ratio is on point—no question about it.

    Flavor: chocolate, vanilla
    Chocolate flavor is absolutely awful; I do not recommend it at all. Do not imagine that it will taste like milk chocolate—it's spoiled-tasting. The one with vanilla is a bit better, but there is a slightly strange aftertaste; however, if you drink it as fast as you can, it works. There are certainly other better proteins on the market, and this one was worth the price from the past, but nowadays it really isn’t.
