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 complete range of essential amino acids. The raw material has a declared solubility of at least 88 % and is sourced from non-GMO soybeans. The product is packed in Germany at a facility that meets IFS, ISO and HACCP standards and each flavour is tested by an accredited laboratory for heavy metals and microbiological 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.
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.
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.
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.
Who is soy isolate for?
- You avoid meat and dairy products: A complete spectrum of essential amino acids from a single plant source, with no milk or lactose.
- You train hard at the gym: Protein contributes to the growth and maintenance of muscle mass. A serving provides up to 26 g of protein and 4,65 g of BCAA.
- You count every gram and calorie: Fat-free, with no more than 1,7 g of sugars per 100 g and around 110 kcal per serving. It also fits into a routine that includes GLP-1 products.
- You keep an eye on the cost per gram of protein: The most affordable protein in our range per serving.
- You care about your bones, not just your muscles: Protein also supports bone health.

Flavor: chocolateI approach the Gym bean brand just in time for Black Friday, based on a friend’s recommendation during an unexpected phone call; so, out of curiosity, I told myself, “let’s see if there’s anything interesting…” Moral of the story: I bought several products at truly competitive prices, and with excellent quality as well. So far, I’ve only had the chance to try two new protein products, and these soy-based Gym bean ones are truly enjoyable, easy to digest, and versatile. I use them to make pancakes, to add to cookie doughs, or to prepare smoothies (milkshakes) or banana ice cream. I probably should have bought from other brands, but it worked out for me because I discovered a new brand I can trust. I’m also curious to taste the rest… ????????????????????????

Flavor: vanillaBecause I started fasting and took it after a long time of vegan protein. When I started my calorie deficit diet, I started with vegan protein and gradually introduced whey protein. This soy protein with vanilla flavour isn’t as sweet—ideal for my taste buds—as usual; it isn’t as smooth as whey when you make a shake. I’ve combined it in both oatmeal porridge and vegan puddings, and the taste is very good.

Flavor: chocolateIt has a sand-like texture, and it doesn’t mix with either yogurt or oats. The only way it can be used is in shakes. The flavor and smell are very good, though.

Flavor: chocolateI don't know why there are so many negative comments. For me it tastes like slightly bland milk with cocoa. I would buy it again. Great deal! It’s very strong when you mix it with oats or something like that. It turns into a creamy texture when you add less water. I recommend it!! But don’t get too much, so there’s more for me ????????
