In the world of fitness, protein supplements are without a doubt one of the most commonly used supplements out there.

But are those big tubs of powder really worth it and can they help you pave your way to an aesthetic, functional physique? In this article, we’ll give you our take on the matter and discuss the different types of protein and their benefits.

Without further ado, let’s see if there’s a faster whey to gains!

What Is Protein, Even?

Besides being a powdered supplement, protein is the building block of our bodies and is in fact, the most essential macronutrient.

The word itself comes from the Greek “protos” meaning primary/first, so that can tell you just how important protein is!

Proteins are basically made up of amino acids that are linked together to form a protein and when we consume protein, the body breaks up the links to absorb the amino acids.

In the body, the functions of protein include but are not limited to:

  1. Protective function

  2. Catalytic function (In order for certain processes in the body to occur, certain proteins called enzymes need to be present)

  3. Structural (Proteins make up the structure of the body and most of its tissues)

  4. Regulative function (Proteins regulate a variety of mechanisms and systems in the body, such as the hormonal system).

Because protein is that important for the body, we need to make sure that we are deriving enough of it from quality sources.

That is, 0.6-1g of protein per lb. of body weight, depending on your body composition and activity levels (i.e someone with more muscle mass that trains more would be on the higher end of the 0.6-1g range)

Protein Supplements

Protein powder is a high-protein dietary supplement that is used to make high protein intake easier or to provide the body with quick, vital protein in times of need or when food intake is not possible.

Some protein supplements contain only one protein source, whereas others contain several.

Animal and plant products can both be used as sources for protein supplements.

Without a doubt, animal protein supplements are the most popular form of protein powders in sports nutrition (made from milk, eggs, meat).

In the past decade, however, plant-based protein supplements have also gained traction, due to the increased interest in plant-based diets, among the fitness population.

Types Of Protein Supplements

As we just mentioned, there are a wide variety of ways and sources used to produce protein supplements, so let’s have a look at the most popular ones!

Whey Protein

Whey protein is by far the most popular protein supplement available.

Its popularity stems from the fact that it is quickly absorbed by the body, taking only 60 minutes to do so.

Protein intake is most important in the morning, just after waking up, and immediately after an exercise.

When it comes to whey protein, we have a few options depending on the manner through which the protein is produced.

  1. Whey concentrate

This type of protein is derived through filtration, during which the proteins are separated from all other contents of the product used for making it.

Though good, whey concentrate contains some fat and lactose, which in many people can lead to stomach discomfort due to lactose intolerance.

Nevertheless, up to 85% of the content in whey concentrate supplements is protein, meaning that it is a good option, especially if you are on a budget.

2. Whey Isolate

This second variation of whey protein is the isolated version, which, as you can guess by the name, undergoes more processing.

More processing means that a bigger part of the protein will be isolated and thus, the end product will have fewer fats and lactose.

This is without a doubt one of the mid-budget options for every trainee.

3. Hydrolyzed Whey Protein

This third type of whey protein is the Bugatti of all proteins as it is the most expensive protein supplement, due to it having the highest protein content.

The protein is derived via a process called “hydrolysis” which breaks down the protein molecules to a certain extent and improves their absorption.

A fun fact here is that hydrolyzed protein is so good at providing amino acids, that it is often added in some intra-workout formulas to support the musculature with a quick amino acid flow


This is another dairy-derived protein supplement that can have a place in a supplement regimen.

Although the amino acid composition of this form of protein is beneficial, absorption is substantially slower (6-8 hours).

Casein has a significant anti-catabolic effect, making it ideal for consumption when fast protein isn't required right away.
