Protein powder is an integral part of many people's diets – whether as a practical training supplement or simply to meet their daily protein needs. While whey protein was considered the undisputed standard for years, more and more people are turning to plant-based alternatives. But one term quickly comes up when it comes to protein powder. vegan protein powder goes: biological value.
You may have heard that animal protein is supposedly superior because it's "better utilized." Or that vegan proteins don't contain all the essential amino acids and are therefore worse for muscle building. But is that really true? In this article, we'll take a closer look at what that means, whether vegan products really do perform worse, and how you can use plant-based protein sources. Because one thing is certain: the quality of a protein doesn't depend on just one factor.
What does biological value actually mean?
Before we examine the biological value of vegan protein powders, let's first explain what it actually means. In short, it describes how well the body can convert ingested protein into its own body protein. The higher the biological value, the more efficiently the body can utilize the protein.
A brief biology lesson: Amino acids are the building blocks of proteins, which the body needs for many processes. The nine essential amino acids are particularly important, as the body cannot produce them itself and therefore must obtain them through food. The biological value of a protein depends on how complete and bioavailable its amino acid profile is.
Biological value – a comparison of plant and animal proteins
As you already know, the higher the value, the better the body can utilize the ingested protein and use it for various functions. To provide a basis for comparison, whole egg serves as the reference with a value of 100. This means that the body can utilize this dietary protein particularly efficiently. All other protein sources are measured against this value. Animal products such as whey, casein, meat, or fish generally have high biological efficiency because they contain all essential amino acids in an optimal ratio. They are therefore considered "complete proteins."
Plant-based alternatives initially offer lower values, as they don't always contain all the necessary amino acids in the ideal amounts. However, this doesn't mean they are inferior – rather, their optimal use requires a more conscious combination of different sources. Protein sources. Although the Biological value of vegan protein powder While the type of animal product is an important factor, it doesn't solely determine the quality of a product. Other aspects, such as digestibility, nutritional profile, and individual tolerance, also play a role. Conversely, the same applies to animal-based alternatives: although they are biologically optimal, their quality can vary significantly – and not every option is equally suitable for everyone.
Biological value of various plant protein sources
Not all plant-based protein sources are created equal – some provide a more complete amino acid profile and are better utilized by the body than others. Crucially, the balance of the amino acids they contain and how well the body can absorb the protein are key factors.Here is an overview of some plant-based sources of vegan protein powder and its biological value.
Pea protein – biological value approx. 65–70
Pea protein scores points with its high protein content and good digestibility. It is particularly rich in lysine, an essential amino acid that is often lacking in many other plant-based sources. However, it contains little methionine, which slightly limits its bioavailability.
Rice protein – biological value approx. 80
Rice protein has a higher amino acid profile than many other sources. Its high methionine content is particularly beneficial, but it contains less lysine. Therefore, to achieve a higher biological value as a vegan protein powder, it is often combined with pea protein.
Hemp protein – biological value approx. 87
Hemp protein offers a naturally good amino acid ratio and also provides additional benefits. Omega-3 fatty acids, which are a particularly practical addition for vegans. It is considered easily digestible and well-tolerated. However, its bioavailability is slightly lower than that of animal protein sources, as it contains less lysine.
Soy protein – approx. 90–96
Soy is one of the few plant-based proteins that represents a nearly equivalent alternative to animal protein. It contains all essential amino acids in sufficient quantities and is considered a complete protein source. It is frequently used as a substitute for whey, especially in the sports sector.
Pumpkin seed protein – approx. 75-80
Besides its good protein content, pumpkin seed protein provides other nutrients such as magnesium and antioxidants. It is highly digestible, although the amounts of lysine and threonine are somewhat lower than in other plant-based protein sources.
Lupin protein – approx. 75
Lupin protein is (rightly) gaining in popularity because it offers a balanced amino acid profile and is easily digestible. It represents a good alternative to soy and provides all the essential amino acids, although not always in an ideal composition.
How vegan protein powder is optimized for high biological value
Pure plant-based protein is often not utilized by the body as efficiently as animal sources, since not all essential amino acids are always present in the perfect ratio. This is precisely where modern vegan products come in: By strategically combining different plant-based proteins, bioavailability can be significantly increased. Many manufacturers rely on blends in which the amino acids complement each other optimally, creating a complete amino acid profile. A classic example is the combination of pea and rice protein. While pea protein is low in methionine, rice protein is low in lysine – together they compensate for these deficiencies and result in a protein source whose quality can be comparable to whey protein.
In addition, other plant-based protein sources are often integrated to further optimize the amino acid profile. Hemp, pumpkin seed, or lupin protein not only provide micronutrients but also contain phytochemicals and unsaturated fatty acids.
The result? Vegan protein powder no longer needs to hide behind animal-based alternatives in terms of biological value. Through clever composition and processing, plant-based proteins can be utilized just as well and simultaneously provide additional nutrients such as fiber, vitamins and antioxidants.

Good vegan protein powder – Is biological value the most important criterion?
While protein content is an important indicator of protein quality, it's only one part of the overall picture. Although it shows how efficiently the body can utilize the protein, there are other crucial factors that play an equally important role.
Digestibility – How well can the body absorb the protein?
Not every protein source is digested equally well. Some people have difficulty with whey protein because it comes from milk and can contain lactose – which can cause digestive issues such as bloating or stomach problems for some. Plant-based alternatives like pea, rice, or hemp protein are often easier to digest and better tolerated.
Nutrient density – more than just protein
Plant-based proteins often provide additional nutrients besides high-quality protein. Fiber and
Individual compatibility – What works best for you?
Every body reacts differently to various nutrients. While some people digest animal protein without any problems, others have difficulty with it. Similarly, not every plant-based protein may be equally well tolerated. What matters is not just the protein's nutritional value on paper, but how your body actually absorbs it and how you feel afterward.
Why plant-based proteins are still a good choice
Even though the amino acid profile is often used as a quality benchmark, plant-based protein sources are proving to be highly competitive thanks to clever combinations and other advantages. Modern vegan protein powders are proof of this: high biological value, well-tolerated, and packed with additional nutrients.
Vegan protein powder & Biological value: How is it affected by processing?
Not only the raw materials, but also the processing plays a crucial role for the Biological value of vegan protein powder. Depending on the manufacturing process, absorption can be facilitated or hindered. Protein isolation is a key aspect. High-quality vegan powders are often offered as isolates – a highly concentrated form with minimal amounts of carbohydrates and...
Digestibility also plays a major role. Some plant proteins contain natural antinutrients, such as phytic acid or lectins, which can inhibit the absorption of certain amino acids.Through specific processing steps such as fermentation, germination, or enzymatic breakdown, these substances are reduced, making the protein more readily available to the body. Another important factor is the product's composition. To achieve high biological value, many manufacturers strategically combine various plant-based sources to obtain a complete amino acid profile. By blending different protein sources such as pea, rice, hemp, or pumpkin seed protein, the biological value of vegan protein powder can approach that of animal-based alternatives.
