The fitness industry has been arguing for years about "Vegan vs. Whey." Sure, protein powder is a good thing. Advocates of whey say: The bioavailability is better. Vegans say: That's not true at all, plus vegan protein is better tolerated by many. Whey fans respond with a shrug: No, we've found something different. In the end, everyone can choose their own protein powder – but is there really a better or worse here? We at Vetain have taken the trouble to give you an overview. First of all: no shame – it doesn't matter at all which protein you choose. We try to be impartial here vegan protein powder vs. Whey to judge. Let's see how that works! We'll start right at the beginning…
… God said: Let there be protein powder.
By the way: When we wanted to speak to God to finally settle the dispute "vegan protein powder vs. whey," we ended up in a phone loop and are still waiting for a response from support today. We promise: If you ever write to us, we will get back to you.
Whey vs. Vegan Protein – what is protein anyway?
Proteins are macronutrients and thus part of a balanced diet. Especially athletes and people with an active lifestyle usually pay attention to meeting their protein needs – even though it is actually important for everyone. Think about it yourself: How much protein do you really consume? Some athletes consume up to 2 grams per kg of body weight. That's quite a lot, especially for a society that mainly eats bread and pasta. Therefore, a normal diet is usually not enough, which is why many turn to protein powders.
Two of the most popular options are whey protein and vegan protein powder. While whey is derived from cow's milk and is considered particularly high quality, vegan protein powders are made from plant sources such as peas, rice, or hemp. These two variants differ in several aspects, including biological value, amino acid profile, digestibility, and ecological footprint. Let's introduce both variants!
More details about whey protein
Whey protein, also known as milk serum protein, is derived from cow's milk. It is produced as a byproduct during cheese production and is then filtered in several steps to obtain the purest possible protein concentrate. Due to its high biological value, whey protein is considered one of the most popular protein sources for athletes. There are different forms of whey protein that differ in their purity level. Whey concentrate contains about 70 to 80 percent protein, while whey isolate has a protein content of over 90 percent reached and contains almost no lactose anymore. The purest form is whey hydrolysate, which has already been enzymatically broken down and can therefore be digested particularly quickly. This makes whey a preferred choice after training.
However, whey protein can be problematic for people with lactose intolerance or milk protein allergy and can lead to digestive issues. Many also criticize that animal welfare is not the priority. And: the quality of whey protein is naturally limited by the quality of animal husbandry itself.
Since animal welfare is currently suffering greatly and very often (among other things) antibiotics, factory farming, etc. are used, it is highly questionable how many truly healthy farm animals still exist on this planet. Let's take a look at vegan protein powder.
What is vegan protein powder and is it better?
Vegan protein powder is derived from plant sources and represents an alternative to animal protein. The most common ingredients are pea, rice, hemp, or soy protein. These plant proteins have the advantage of being lactose-free and are therefore often tolerated by special groups such as those with lactose intolerance. However, each plant protein source has its own strengths and weaknesses. The biggest criticism: not a single plant protein has a complete amino acid profile. Let's quickly take a detour into the …
… amino acid profile
An amino acid profile describes the composition of a protein in terms of the amino acids it contains. There are a total of 20 proteinogenic amino acids, nine of which are essential. Essential amino acids, also called EAAs (leucine, isoleucine, valine, methionine, lysine, phenylalanine, threonine, tryptophan, and histidine), must be obtained through food because the body cannot produce them itself. Branched-chain amino acids (BCAAs) are especially popular in sports: leucine, isoleucine, and valine. A complete amino acid profile ensures better protein utilization.
Back to the topic: vegan protein powder vs. whey.
As described, no vegan protein has a complete amino acid profile. Pea protein has a relatively good profile and contains particularly high amounts of lysine. Rice protein, on the other hand, is rich in sulfur-containing amino acids like methionine but contains little lysine. Hemp protein scores with healthy fatty acids but has a lower protein content. To optimize biological value and the amino acid profile, blends of different plant proteins are often made. These so-called multi-component proteins combine several plant sources to ensure the most complete supply of essential amino acids possible. The vegan Protein powder by Vetain has an exciting profile precisely because of this approach!

An advantage of vegan protein powders, on the other hand, is better tolerance for people with milk allergies or digestive problems. In addition, they have a lower ecological footprint than whey protein because their production consumes fewer resources. And of course, no animal is confined under impossible conditions.
Vegan protein powder vs. whey: The biggest differences between plant and animal proteins
The fundamental difference between plant and animal proteins lies in their biological value and protein bioavailability – the biggest point of contention among fitness enthusiasts debating vegan protein powder vs. whey. Animal proteins, especially whey protein, contain all essential amino acids in an optimal ratio for the human body. Not least because the animal body is simply very similar in function to the human body. The protein is structurally almost identical to what is used in our body.
Plant proteins, on the other hand, are often limited in one or more essential amino acids. For example, rice protein contains little lysine, while pea protein is rather low in methionine. However, this disadvantage can be compensated by a clever combination of different plant proteins.
Another aspect is digestion – we are not referring to digestive problems caused by dairy products, but: animal proteins are generally digested faster by the body, while plant proteins have a somewhat slower availability. However, this can also be an advantage, as many describe plant proteins as more filling. So you can see, it’s not that simple to say definitively what is better. Regarding the ecological Sustainability However, plant-based proteins clearly perform better as their production requires less water and agricultural land and causes lower CO₂ emissions.
Vegan protein powder vs. whey – which choice for whom?
The choice between whey protein and vegan protein powder depends on several factors, including personal goals, tolerance, environmental awareness, and taste preferences.
Whey protein is ideal for …
… active athletes looking for a high-quality amino acid profile. Its high biological value allows practical utilization in the body, and it often contains all essential amino acids. Additionally, Whey protein is usually quickly digested by the body.
Vegan protein powder is suitable for …
… people who cannot tolerate dairy products or avoid animal products for ethical and ecological reasons. It is also an interesting option for those who are lactose intolerant or vegans. Regarding sustainability, plant-based protein is clearly advantageous, as its production causes fewer greenhouse gases, requires less water, and uses less agricultural land. However, some plant proteins have a lower biological value, which can be compensated by multi-component blends.
There are, of course, taste differences as well: Whey protein is often creamier and more neutral, while vegan protein powders can taste earthier or more plant-like depending on the source. Many protein powders also contain additives like artificial sweeteners or thickeners, which vary depending on the product and brand. Solubility also plays a role – whey protein usually dissolves better in water, while plant proteins can have a slightly thicker consistency.
At Vetain, we saw a real problem in the market: The demand for vegan protein powder was high – including for us. Because for us, the question "vegan protein powder vs. whey" was a no-brainer. We, the founders of Vetain, noticed that we often had problems with digestion and skin when using conventional protein powders.
Unfortunately, we couldn't find any vegan protein powder that met our standards. The products were either:
-
sandy
-
disgusting
-
packed with flavors and artificial additives like sweeteners and anti-caking agents
-
or all of it.
So we thought: Let's just make our own! And many hours, days, weeks, months later: Our vegan protein powder.

The products from Vetain
At Vetain, one thing is especially important to us: the right way to treat ourselves and our planet. Therefore, we did not want to compromise on either quality or sustainability in our products. And even though it gave us headaches more than once, we finally made it and have now even expanded our product range to Toppings and Vitamins can expand.
For us, the priority remains that we don't use any artificial gimmicks just to make it taste better. You can always rely on the clean ingredients of our products! And regarding sustainability: We use as little plastic as possible. Instead, we rely on cardboard and, for example, don't include measuring scoops – everyone basically has a tablespoon at home anyway. That's enough, don't you think?
Vegan protein powder vs. Whey: Which protein is right for you?
We can't answer that for you. At the end of the day, you have to test it yourself because only you know what fits better into your daily life and your body. This much we can say: We can't imagine life without protein powder anymore. It's one of the easiest ways to meet your protein needs. The most important things to watch for when buying – whether vegan protein powder or Whey – are:
-
No artificial sweeteners.
-
No ingredients that are only listed as numbers and letters (like colorants, for example).
-
For Whey: dairy cow. The best Whey comes from happy cows, and cows are happiest out in the pasture.
-
For vegan protein: an intelligent combination of several plant-based protein sources. As a rule of thumb: there should be at least two different protein sources from different plant species. For example, rice (a type of grain) and pea (a legume). A poor combo would be pea (legume) and lentil (also a legume). Here the amino acid profiles are too similar to create a truly balanced ratio.
The choice between Whey protein and vegan protein powder depends, as described, on many factors – including tolerance, diet, and personal goals. So we don't allow ourselves to give you a recommendation here. But we hope that with our article "vegan protein powder vs. Whey" were able to give a comprehensive overview on the topic and you now have a good foundation on which you can make this decision for yourself.
And honestly: This isn't about the dreaded tattoo that you have to carry on your forehead for the rest of your life. You can just try it out! Most people who have a strong opinion about it have already tried both and are now advocates of THEIR truth. And if someone has a strong opinion without having tried both... you shouldn't listen to that person anyway.
One more note: It should be clear by now, but "vegan Whey Protein" obviously doesn't exist. It's either Whey, or it's vegan.
