Whey, Without the Moo - What is Animal-Free Protein Powder?
No Cow, All Science
*end of post*

Just kidding, while that is true, there’s more to it. 

So, let’s get into it. 

What is Animal-Free Protein Powder?

At Natreve, we are proud to bring you MOOLESS, a one of a kind animal-free whey protein powder, made with Perfect Day, that provides a whey experience, without the cows. 

Thanks to advances in food technology, cellular agriculture is making a splash in our food ecosystem. 


Enter precision fermentation


To learn more about the process, check out this video.


Step 1:

To make animal-free protein, microflora (microorganisms such as bacteria, yeast, or fungi) are fed the genetic blueprint corresponding to cow’s milk protein. 

Step 2: 

In fermentation tanks, the flora grazes on plant-based inputs (flora food) while mixing with the genetic blueprint of cow’s milk and converts the flora food into animal-free milk protein. 

Step 3:

Voila! The fermentation process produces animal-free milk protein that is identical to the protein found in cow’s milk. Without the cow!

More than just cool science and environmentally supportive food supply, MOOLESS provides the taste, texture, and nutrition of whey protein powder, without the cow.

Perfect Day’s animal-free whey protein is molecularly-identical to traditional whey protein found in cow’s milk but is made via fermentation, without any animal inputs. Learn more about Perfect Day’s process to make our protein here.


What are the Environmental Benefits?


Compared to traditional dairy protein from cows, the animal-free whey protein we use produces up to 97% fewer greenhouse gas emissions and uses up to 99% less water and up to 60% less non-renewable energy. And because there are no animal products used, MOOLESS is 100% lactose- and hormone-free. 

Less greenhouse gas emissions, less water, and less energy mean MOOLESS, made with Perfect Day animal-free whey protein, is kinder, greener, and better for you and the planet. 

Natreve believes in Perfect Day’s vision of a kinder, greener tomorrow. MOOLESS brings that vision to life and provides a delicious and convenient protein option for consumers looking to add protein to their daily diet while making kinder, greener choices.


An ISO-certified, third-party validated report of Perfect Day’s animal-free protein found that it reduces:

o   Water consumption by up to 99%

o   Greenhouse gas emissions by up to 97%

o   Energy use by up to 60%

Is it Vegan?

Some may consider MOOLESS vegan-friendly because no animal inputs are used, and there are no animals involved in the process whatsoever.

The animal-free protein used in MOOLESS is made via fermentation, with zero animals used in the process, so it may be suited for a vegan diet, depending on how you define it.

There are many reasons for following a vegan diet and lifestyle, and we encourage each person to decide which Natreve protein powder is right for them.

However, it is not dairy-free, so we refer to MOOLESS as animal-free protein powder, not vegan protein powder.

Because animal-free whey protein powder is molecularly-identical to whey protein from cows, it is not suitable for those with a milk protein allergy, which is why you will see a “contains milk allergen” declaration on the packaging.


Even though it doesn’t come from cow’s milk, people with a milk allergy can still have an allergic reaction to animal-free whey protein and should avoid it just as they would avoid cow’s milk.


Is it plant-based?

It is not plant-based because it’s not derived from plants, like a pea protein would be. Instead, microflora is given the genetic blueprint of whey protein, and through the process of fermentation, real milk protein (identical to what cows produce) is made.

MOOLESS is free from lactose, hormones, and antibiotics.


If you are looking for a plant-based and 100% vegan option, we recommend Natreve Vegan Protein Series.


What flavors are available?

MOOLESS is available in four delicious flavors - Vanilla Bean Cupcake, Chocolate Fudge Brownie, Cookies and Cream, and Strawberry Shortcake.

Vanilla Bean Cupcake tastes like a birthday party without the sugar crash. Animal-free whey protein powder with no added sugar. Simple and classic.

Chocolate Fudge Brownie is reminiscent of family dinners that culminate in mom’s famous dessert. All the nostalgia of traditional dairy-based desserts, without the animals. Rich and indulgent.

Cookies and Cream like dipping cookies in milk while watching your favorite Saturday morning cartoons or taking a trip to the ice cream parlor, but better and completely animal-free. Creamy goodness made with real cookie pieces. 

Strawberry Shortcake takes you back to warm summer afternoon picnics drenched in whip cream and hot sun. Lactose-free, soy-free, hormone and antibiotic-free. Light and refreshing. 


What are the Nutritional Benefits?

MOOLESS is molecularly identical to conventional whey protein powder, delivering all the nutritional benefits and a lower environmental footprint.  

MOOLESS is the first animal-free whey protein powder made with protein that generates up to 97% fewer greenhouse gas emissions than conventional production methods.

Each serving of MOOLESS contains 20 grams of protein and a full-spectrum digestive enzyme to support digestion. Read this if you like science and are interested in more information on the bioavailability of Perfect Day protein.


How Do I Use It?

Simply mix one packet into smoothies or with water or your favorite plant-based beverage to meet your protein needs.


Key Takeaways

MOOLESS is perfect for those who care about climate change and creating a better tomorrow while simultaneously looking to fuel their daily lives with a complete protein shake.
