Soy Protein vs. Whey Protein Isolate – Everything You Need To Know

As an athlete, you are not only fit during training but are usually also experts in nutrition issues. You point out the importance of a balanced, healthy diet for achieving your goals, achieving performance improvements up to optimal training results, and, more generally, for your own well-being. It is not called for anything – the healthy and fit exterior comes from within. Therefore, you live according to a certain diet plan, as individually tailored as possible to you and your Traininsgziel. A balanced balance of the nutrients absorbed is a central part of success but can present you with many challenges in everyday life. In the fitness scene, food-supplementing proteins are a big topic, especially in the studio around strength training. And not for nothing, as muscle growth and good regeneration are largely based on a sufficient protein supply. The supplement market offers a wide variety of products for easy protein supply – including variants with high-quality soy protein and/or whey protein isolate.


What does the body use proteins for?


Protein is essential when building muscle mass and about the regenerative processes after the workout. One of the advantages is that e.B. soy and whey proteins are available to the body very quickly for use. This property should make protein an important food component at breakfast, and after training, as at this point, the stores are emptied and replenished by the long night rest and training. Also, protein saturates well, a clear plus in the context of a calorie-reduced diet.

Proteins in powder form can be easily and easily mixed into a shake. This is quickly prepared, tasty, and provides an extra portion of protein without much preparation or high cost.

Most athletes tend to the whey variants (concentrate and isolate), where whey protein isolate is the purest form of whey protein. Whey protein is made from whey, a ‘waste product’ in cheese production, making it one of the milk proteins. It has a high biological value, is particularly well absorbed by the body, and can be processed quickly. Whey protein isolate is the most expensive variety of whey protein species due to an elaborate manufacturing process. Still, it is particularly rich in protein while at the same time poor in fat and sugar. The protein content is around 90%, making it one of the absolute top products in our range, has an extensive amino acid profile, and is an absolute protein booster taken as a shake. Another advantage – due to the complex production process, whey protein isolate is literally an ‘isolated’ form of protein and therefore virtually lactose-free. This allows it to be used by athletes with lactose intolerance.

Due to the numerous use of protein shakes by athletes from various sports, there is a wide range of products from different manufacturers in numerous flavors.

Also, soy protein isolate is rich in protein, has a good taste, the powder is well soluble. The finished shake differs by a slightly different consistency and a slight own taste.

For those affected by lactose intolerance, vegans, or vegetarians, the soy protein isolate offers a well-digestible, 100% herbal alternative. The protein powder is GMO-free and contains at least 90% protein, comparable to the whey protein isolate in terms of protein content. Even as a pure vegan, you don’t have to do without protein! Furthermore, the powder is almost free of fat, without sugar, and has only a low carbohydrate content – all at an attractive price. The amino acid balance is slightly lower for every 100g of protein, but the soy protein also contains an extensive amino acid profile with all EAA (incl. BCAA).

Soy protein is obtained directly from the soybean, a staple food in Asia for centuries. In an elaborate manufacturing process, superfluous fat and carbohydrates are removed, hence the low proportions that allow use even in diet and definition phases.



No matter which product variant you choose: A protein shake for breakfast and after the workout enriches your protein supply and creates a good basis for the best results in muscle building and regeneration. The shakes are used to enrich your normal diet and should not be used to substitute for a balanced and varied diet.

Both variants contain around 90% protein and can also be used for athletes with lactose intolerance. If you are looking for a purely plant-based protein supply, soy protein provides a high-quality alternative to the classic milk protein, which can be used to the same extent.

The decision is up to you.


Alternatives for your protein supply and usage variants for protein powders

There are a variety of ways to integrate protein into the diet. The normal diet and consumption of dairy products, eggs, meat, fish, vegetable alternatives, or various protein-rich vegetables, etc., often only cover part of the need, especially for intensively trained strength athletes. Therefore, protein shakes are high in favor of many athletes, as they are quick and easy to prepare.
