Protein is an essential macronutrient that plays a crucial role in our body's function. It is a vital energy source and is needed by our body to grow and repair cells.
In a balanced diet, protein should make up 10-35% of a person’s caloric consumption per day.
With so many options out there, it can be challenging to choose which one meets your needs. Understanding the differences and similarities between vegan protein vs whey protein can help consumers like you make informed decisions aligned with your health goals and personal preferences.
It's no wonder why protein supplements, such as protein powders, have gained increased popularity in recent years. When it comes to choosing one, the battle often boils down to animal protein (whey) and plant-based options.
So which is better? Both types are a concentrated source of protein, making them popular among athletes, fitness enthusiasts and health-conscious individuals.

Key Takeaways
Protein comes from a wide range of foods and it is important that you get enough protein in your diet every day.
According to the Dietary Guidelines for Americans, the recommended dietary allowance (RDA) for protein is 0.8 grams per kilogram of body weight. This translates to about 54 grams of protein for an adult weighing 150 pounds.
What Is Whey Protein?
Whey protein, derived from cow's milk, is known for its rich taste and is often favored by those without dietary restrictions.
Whey is a byproduct of the cheesemaking process; specifically, the thin liquid portion of milk that separates from the curds.
The leftover whey is then processed into a powder, with its fat, carbohydrates and water content removed.
Whey protein powders come in different forms which include:
Whey protein powders are widely available and easy to find at your local grocery stores and online. They come in an unlimited variety of artificial flavors.
What Is Vegan Protein?
Vegan protein is a type of protein that is sourced from plants, as opposed to animal-based sources. It is crucial for energy, tissue and cell repair, and proper blood circulation.
Vegan proteins can be found in yellow peas, brown rice, peanuts, chia seeds or hemp, to name a few.
Many plant proteins are incomplete and are lacking at least one of the essential amino acids. However, some foods like quinoa and buckwheat are complete sources of protein.
This is why vegans should mix their dietary sources of protein to make sure that they’re getting all of the essential amino acids their body needs.
A primary example of a vegan protein supplement is a plant based protein powder. It offers an alternative source of protein for individuals with lactose intolerance, diabetes, or those following a vegan diet or flexitarian lifestyle.
Like whey, vegan protein powder also comes in the form of isolates and concentrates which typically contain 80% more protein by weight or over 20 grams of protein per serving.
Difference Between Vegan Protein vs Whey Protein
Whey protein tends to absorb quickly, potentially spiking blood sugar levels. On the other hand, proteins from pea or other plants usually digest slower and may assist in maintaining steadier blood sugar levels.
Furthermore, plant proteins often contain additional nutrients such as zinc, which individuals might not get from whey protein alone. Vegan protein is also rich in phytonutrients and antioxidants which some sources of animal protein do not have.
Similarities Between Vegan Protein vs Whey Protein
Despite their origins, both whey and plant-based proteins can play a pivotal role in improving body composition when combined with regular exercise. They offer comparable amounts of calories per serving, which is something to consider when managing your diet for health or fitness goals.
In terms of amino acid profile, whey contains all nine essential amino acids in higher concentrations. You can get the same benefits from vegan proteins if you observe a varied diet and consume more plant based protein sources.
Also, most manufacturers of plant based protein powders combine multiple plant proteins to ensure the presence of all essential amino acids and branched chain amino acids (BCAAs) in their products.
Moreover, both whey and plant-based proteins can be found in forms that minimize digestive discomfort, thus supporting gut health.
Which is Better for Your Fitness Goals?
When selecting a protein source to supplement one's diet, consider if it aligns with your specific fitness objectives.
Whey protein is often acclaimed for its remarkable prowess in building muscles due to its status as a complete protein, possessing all nine essential amino acids required for muscle recovery.
Vegan protein equally plays a critical role in supporting muscle growth. There’s scientific evidence that plant-based proteins can stimulate muscle protein synthesis to the same degree as whey protein.
While advertising may tout one type of protein as a "superfood," it all often comes down to balancing protein intake with carbohydrate consumption and other dietary needs to support muscle building.
Understanding Nutritional Profiles and Benefits
Protein powders, whether derived from whey or assorted plants, cater to a multitude of nutritional needs and support diverse bodily functions.
Key Nutrients in Whey Protein
Whey protein, often a preferred choice for those without lactose intolerance, stands out for its high-quality amino acid profile, which is critical for muscle recovery and development.
The presence of lactase, an enzyme which aids in the digestion of lactose, makes whey protein suitable for those who have mild stomach issues with dairy products.
Additionally, whey protein contains bioactive compounds that may offer protective benefits against cardiovascular disease.
Nutritional Benefits of Vegan Protein Powder
Brands focusing on plant-based formulas often fortify their products with vitamins and minerals not typically found in animal-sourced options. The exclusion of animal products appeals to those seeking a more compassionate and sustainable lifestyle, while still supporting their nutritional needs.
Digestibility and Allergen Considerations
Whey protein has a reputation for sometimes causing digestive issues such as diarrhea in individuals sensitive to dairy products. Whey protein goes through hydrolysis during digestion, where it is broken down into smaller peptides, which can affect how the body absorbs its nutrients.
Conversely, vegan protein powders are known for their allergen-friendly qualities, presenting a viable option for those unable to consume milk or who prefer plant-based sources.
Environmental and Ethical Considerations
Consumers sometimes consider the broader impacts of their choices on their environmental and societal impact. When examining the production cycle of protein sources, one must evaluate its sustainability, particularly how they affect land use and carbon emissions.
Plant-based protein production often involves less water and land use. On the other hand, whey protein production can have a significant environmental footprint. It requires large amounts of water and contributes to greenhouse gas emissions.
Examining the Sustainability of Vegan Protein
When evaluating the sustainability of vegan protein powders, one standout example is pea protein. As a legume, peas improve soil health by producing nitrogen, which can reduce the need for chemical fertilizers. Moreover, pea protein is produced with considerably lower resources than dairy products.
Protein Source | Sustainability Factor | Dietary Benefit |
|---|---|---|
Pea Protein | Low water and land use; nitrogen-fixing legume benefits soil | High in dietary fiber; lactose-free |
How to Decide What’s Right for You
Choosing the right protein supplement often depends on an individual's unique dietary requirements and fitness aspirations.
Those with allergies to dairy or sugar might gravitate towards vegan protein powders, which are free from lactose and often lower in sugar content. A vegan protein blend that may include ingredients such as pumpkin seed, rice, or cereal grains may be a beneficial alternative to whey.
Conversely, individuals with no such constraints might find whey protein an optimal choice. Factoring in personal allergies, such as sensitivity to nuts, or personal preferences is important.
Protein powder is a tasty way to eat well and build muscle, but not all are equal. Discover some of the best vegan protein powders. and what sets them apart from the rest.
Frequently Asked Questions
Whether or not vegan protein is better than whey is entirely based on your individual needs and preferences. There is a misconception that whey protein is far superior than plant based protein but neither is better than the other. For instance, pea protein powder is generally well-tolerated and contains a high amount of branched chain amino acids just like whey. Soy protein powder is also considered a complete protein source, which means you get the nine essential amino acids from it, similarly to whey protein powder.
Plant protein is just as effective in building muscle mass as whey protein. You can get the same protein content from vegan protein powders (about 20-30 grams) as whey protein powders. Research published in the Journal of Nutrition revealed that a type of plant protein (mycoprotein) can promote muscle growth in the same way as whey protein. Adult participants who consumed a high-protein diet from plant-based sources gained a similar amount of muscle mass and fiber size, as well as developed increased strength as those who were on a high protein diet from animal sources.
