Vegan Protein vs Whey: Which is Better for You?

Protein is an essential macronutrient that plays a crucial role in our body's growth, repair, and maintenance. It is vital for maintaining muscle mass, supporting bone health, and promoting a healthy immune system. This is why it is no surprise that protein supplements, such as protein powders, have become increasingly popular over the years.

Protein supplement powders are either derived from cow’s milk (whey), or they are plant-based (vegan). Both types are popular among fitness enthusiasts, athletes, and any health-conscious people looking to supplement their protein intake. But with so many options available, it can be challenging to know which is the most nutritional. In this blog, we will dive deeper into the differences between vegan protein and whey protein and explore which type is more nutritious.

The Basics of Vegan Protein vs Whey Protein

Let's first consider the basics. Vegan protein powder is derived solely from plant sources such as soy, peas, rice, hemp, and others. In contrast, whey protein is a type of protein powder that is derived from milk. It is a byproduct of the cheese-making process and is rich in amino acids.

Both vegan protein and whey protein powders come in different forms, including isolates, concentrates, and blends. Isolates are the purest forms of protein, containing at least 90% protein with almost no carbohydrates and fats. Concentrates, on the other hand, contain a lower percentage of protein and may contain more carbohydrates and fats. Blends, as the name suggests, are a mixture of different protein sources that can provide a more diverse amino acid profile.

Nutritional Benefits of Vegan Protein vs Whey Protein

One of the primary factors that determine the nutritional value of a protein powder is the amino acid profile. Amino acids are the building blocks of protein, and they play a crucial role in muscle building, repair, and maintenance. Our bodies can produce some amino acids, but there are nine essential amino acids that we need to get from our diet. These are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.

Complete amino acid profile

Whey protein contains all nine essential amino acids. It is particularly rich in leucine, which is essential for muscle growth and repair. Plant-based protein powders, on the other hand, often lack one or more essential amino acids. The best vegan protein powders (such as our HERMOSA one) combine different plant-based protein sources to ensure that all essential amino acids are present. For example, pea protein is rich in lysine; pumpkin, sesame and hemp seeds contain leucine, and rice protein is high in methionine. Combining these sources creates a complete amino acid profile.

Fast release or slow release

Another factor to consider when choosing between vegan protein and whey protein is the absorption rate. Whey protein is rapidly absorbed by the body, which makes it an excellent option for post-workout recovery. On the other hand, vegan protein powders may have a slower absorption rate, which means that they provide a sustained release of protein over time.

Extra nutrients

In terms of other nutritional benefits, vegan protein powders are often higher in fibre, vitamins, and minerals than whey protein powders. For example, pea protein is rich in iron, while hemp protein is high in omega-3 fatty acids. This can be particularly good for people who follow a plant-based diet and may not get enough of these nutrients from their food alone.

Supplementing Plant-Based Diets with Vegan Protein Powder

Plant-based diets have gained popularity over the years, due to their potential health benefits, ethical reasons and positive impact on the environment. As most people are aware, many plant-based foods are not complete protein sources - so vegan protein powders are an ideal supplement to ensure you get your daily protein requirements.

But not all vegan protein supplements are equal. As mentioned earlier, make sure you choose a protein powder that combines different plant-based protein sources to create a complete amino acid profile. It is also important to check the label for added sugars, artificial flavours, and other additives that may detract from the nutritional value of the powder.

Potential Drawbacks of Incorporating Vegan Protein Powder into Your Diet

While vegan protein powder has many nutritional benefits, there are also some potential drawbacks to consider. One of these is that plant-based protein powders may not be as easily digested as whey protein powders. This is because plant-based proteins contain more fibre, which can slow down the digestion process. Some people may also experience issues such as bloating, gas or constipation with vegan protein powders.

Another potential drawback is that some plant-based protein sources may contain ‘anti-nutrients’, which can interfere with nutrient absorption. Soy protein, for example, contains phytic acid, which can bind to minerals such as zinc and iron, making them less available to the body. You can avoid this by choosing protein powders - such as HERMOSA vegan protein powder - made from non-GMO soybeans that have been soaked, sprouted, or fermented before they are processed into protein powder.

So, what’s best - vegan or whey? 

In conclusion, both vegan protein and whey protein have their nutritional benefits and drawbacks. 

Whey protein is a complete protein source that is rapidly absorbed by the body and is particularly beneficial for post-workout recovery. Vegan protein powders, on the other hand, are often higher in fibre, vitamins, and minerals than whey protein powders, and are an excellent way to supplement protein for anyone following a plant-based diet.


At HERMOSA, we believe that both types of protein have their place in a healthy, well-balanced diet. That's why we offer a range of high-quality protein powders, including vegan protein powders made from a variety of plant-based sources, and whey protein powders derived from grass-fed and hormone-free cows. Whether you're looking to build muscle, support your immune system, or simply supplement your daily protein intake, we've got you covered.

So which is more nutritional - vegan protein or whey protein? The answer depends on your individual nutritional needs and dietary preferences. We encourage you to try both types and see which works best for you. With our range of protein powders, you can be sure that you're getting the best quality and nutrition for your body.
