Whey Protein Explained: Benefits & Uses

Protein is one of the biggest wellness trends of 2025, but why is it so important? What are the benefits of protein? Are there different benefits for wellbeing when comparing plant protein and whey protein? We’re so glad you asked, because we know a thing or two about the benefits of protein, and goodness gracious, it’s far more than just a muscle recovery supplement.

Why You Need Protein

Protein is a macro nutrient, one of the body’s most important building blocks. This means we need it in larger amounts every day to maintain optimal health. Every cell in your body — whether in your muscles, skin, bones, or immune system — relies on protein to function. 

So if you’re wondering how much protein you need to reach your daily quota, or you’re looking for the perfect protein supplement to match your goals, you’re in the right place! 

What is Whey Protein?

Whey protein is one of the most popular protein sources on the market, but what is it? During the cheese-making process, milk is separated into curds and liquid. Then, the liquid is collected, gently filtered, and dried into a whey protein powder that’s easy to use!

Whey protein is rich in all nine essential amino acids, making it a complete protein source. All nine essential amino acids (which our bodies can’t make on their own) are needed to create proteins in the body, which means they’re key for muscle health, energy production, immune function, and overall vitality.

Whey protein vs plant protein

Plant proteins don’t always include full amounts of every amino acid from their one plant source meaning that without combining multiple sources, like pea and rice protein, you aren’t receiving the same benefits. But not all plant-proteins are lacking — our Clean Plant Protein is a plant based protein source thoughtfully formulated so you get all nine essential amino acids in every serving. Perfect for when you’re needing a plant-based complete protein alternative!

Flavour and texture are other considerations when it comes to the difference between whey protein and plant-based protein. Whey protein is naturally smooth and creamy; plant-based proteins, while still smooth and delicious, have a less creamy flavour and a thicker taste. Ultimately, both have a place in a balanced diet; the choice comes down to intended purpose and desired outcomes.

Whey concentrate vs whey isolate

When it comes to whey, you’ll usually see two types on the shelf: concentrate and isolate. Both are complete proteins, but the difference lies in how they’re processed and what ends up in the final scoop. While both whey protein concentrate (WPC) and whey protein isolate (WPI) are excellent protein sources, the main difference comes down to their composition and processing.

Whey Protein Concentrate (WPC) → around 70–80% protein, with slightly higher levels of lactose, carbs, and fat, giving it a creamier taste and texture.

Whey Protein Isolate (WPI) → over 90% protein, further refined for lower lactose and fat, making it easier to digest for those who are sensitive to dairy.
