Protein powder is a fixed part of many people's diets – whether as a practical training supplement or simply to meet daily protein needs. While whey protein has long been considered the undisputed standard, more and more people are turning to plant-based alternatives. But one term quickly comes up when it comes to vegan protein powder goes: biological value.
Maybe you have heard that animal protein is superior here because it is "better utilized." Or that vegan proteins do not contain all essential amino acids and are therefore worse for muscle building. But is that really true? In this article, we take a closer look at what that means, whether vegan products really perform worse, and how you can use plant-based protein sources. Because one thing is certain: The quality of a protein does not depend on just one factor.
What does biological value actually mean?
Before we check vegan protein powder for biological value, we first explain what it actually means. In short, it describes how well the body can convert an ingested protein into its own body protein. The higher the biological value, the more efficiently the body can use the contained protein.
A brief biology excursus: Amino acids are building blocks of proteins that the body needs for many processes. Especially important are the nine essential amino acids that the body cannot produce itself and therefore must obtain through food. The biological value of a protein depends on how complete and well available this amino acid profile is.
Biological value – 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 create a basis for comparison, whole egg serves as a 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 like whey, casein, meat, or fish generally have a biologically high availability because they contain all essential amino acids in an optimal ratio. They are therefore considered "complete proteins."
Plant alternatives initially offer lower values because they do not always contain all the required amino acids in ideal amounts. However, this does not mean they are worse – rather, their optimal use requires a somewhat more conscious combination of different protein sources. Although the biological value in vegan protein powder an important factor, but it alone does not say everything about the quality of a product. Other aspects such as digestibility, nutrient profile, and individual tolerance also play a role. Conversely, this is also true for animal alternatives: although they are biologically optimal, they still differ significantly in quality – and not every option is equally suitable for every person.
Biological value of various plant protein sources
Not all plant protein sources are the same – some provide a more complete amino acid profile and are better utilized by the body than others. The key factor is how balanced the contained amino acids are and how well the body can absorb the protein. Here is an overview of some plant sources for vegan protein powder and their biological value.
Pea protein – biological value approx. 65–70
Pea protein scores with a high protein content. It is especially rich in lysine, an essential amino acid that is often lacking in many other plant sources. However, it contains little methionine, which slightly limits its bioavailability.
Rice protein – biological value approx. 80
Rice protein has a higher amino acid balance than many other sources. Its high methionine content is particularly good, but it contains less lysine. To achieve a higher biological value as a vegan protein powder, it is therefore often combined with pea protein.
Hemp protein – biological value approx. 87
Hemp protein offers a naturally good amino acid profile and additionally provides Omega-3 fatty acids, which are especially a practical addition for vegans. However, its bioavailability is somewhat lower than that of animal protein sources because it contains less lysine.
Soy protein – approx. 90–96
Soy is one of the few plant proteins that represent an almost equivalent alternative to animal protein. It contains all essential amino acids in sufficient amounts and is considered a complete protein source. It is often used as a substitute for whey, especially in sports nutrition.
Pumpkin seed protein – approx. 75–80
Besides a good protein content, pumpkin seed protein provides other nutrients like magnesium and antioxidants. Digestibility is high, but the amounts of lysine and threonine are somewhat lower than in other plant protein sources.
Lupine protein – approx. 75
Lupine protein is (rightly) gaining popularity as it offers a balanced amino acid profile and is easy to digest. It is a good alternative to soy and provides all important amino acids, although not always in an ideal composition.
How vegan protein powder is optimized for high biological value
Pure plant protein is often not utilized quite as efficiently by the body as animal sources because not all essential amino acids are always present in the perfect ratio. This is exactly where modern vegan products come in: by deliberately combining different plant proteins, digestibility can be significantly increased. Many manufacturers rely on blends where the amino acids complement each other optimally and together form a complete profile. A classic example is the combination of pea and rice protein. While the former contains little methionine, rice protein is low in lysine – together they balance these deficiencies and create a protein source that can be comparable in quality to whey protein.
Additionally, other plant-based protein sources are often integrated to further optimize the amino acid profile. Hemp, pumpkin seed, or lupine protein not only provide micronutrients but also contain secondary plant compounds and unsaturated fats. Besides the right composition, processing also plays a crucial role. Modern manufacturing methods isolate the protein and make it especially easy to digest. Some products also contain added free amino acids or fermented proteins to further improve absorption.
The result? Vegan protein powder no longer has to hide behind animal-based alternatives in terms of biological value. Through clever composition and processing, plant proteins can be utilized just as well and at the same time provide additional nutrients like fiber, vitamins, and antioxidants.

Good vegan protein powder – Is biological value the most important criterion?
It is an important indicator of protein quality – but only 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 trouble with whey because it comes from milk and can contain lactose – which can cause digestive issues like bloating or stomach problems for some. Plant-based alternatives like pea, rice, or hemp protein are often easier and better tolerated by these individuals.
Nutrient density – more than just protein
Plant proteins often provide additional nutrients alongside high-quality protein. Fiber and fats like omega-3 from hemp are part of a balanced diet, and minerals like magnesium, iron, and zinc contribute to important bodily functions. While animal proteins are usually considered in isolation, plant sources offer a broader spectrum of nutrients that enrich the overall diet.
Individual tolerance – What works best for you?
Every body reacts differently to various nutrients. While some can easily digest animal protein, others have difficulties with it. Likewise, not every plant protein may be equally well tolerated. What matters is not just the value on paper, but how your body actually absorbs the protein and how you feel with it.
Why plant-based proteins are still a good choice
Although the amino acid balance is often used as a quality benchmark, it turns out that plant-based protein sources are absolutely competitive through clever combinations and additional benefits. The proof of this is modern vegan protein powders: high biological value and packed with additional nutrients.
Vegan protein powder & biological value: How is it influenced by processing?
Not only the raw materials but also the processing plays a decisive role for the biological value of vegan protein powder. Depending on the manufacturing process, absorption can be facilitated or hindered. An important aspect is protein isolation. High-quality vegan powders are often offered as isolates – a highly concentrated form with minimal amounts of carbohydrates and fats. This process increases bioavailability because the protein is present in a particularly pure and easily digestible form.
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 special processing steps like fermentation, germination, or enzymatic breakdown, these substances are reduced, making the protein more available to the body. Another point is the product's composition. To achieve a high biological value, many manufacturers deliberately combine different plant sources to obtain a complete amino acid profile. By mixing various protein sources like pea, rice, hemp, or pumpkin seed protein, the biological value of vegan protein powder can approach that of animal-based variants.

Conclusion: Vegan protein powder & biological value – a strong combination
Biological value is an important factor when it comes to the quality of a protein – but by no means the only one. Thanks to clever combinations, modern processing, and targeted optimization, vegan protein powder now match animal-based alternatives in every way. It not only provides high-quality protein but often also additional nutrients like fiber, vitamins, and unsaturated fatty acids.
Whether for conscious nutrition or as a supplement to training – plant-based protein sources have long been a fully viable option. Those who pay attention to good composition and processing quality can achieve a good protein supply with vegan protein, without any compromises.
