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

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 some of the different types of protein and their benefits.

What Is Protein?

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 getting enough of it from quality sources.

That is, 1.5-2g of protein per kg of bodyweight per day, 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 1.5 to 2g range)

Protein Supplements

Protein powder is a high-protein dietary supplement, which 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.

Animal protein supplements are the most popular form of protein powders in sports nutrition (made from milk, eggs, meat) and more recently collagen.In the past decade however, plant-based protein supplements have gained in popularity, due to the increased interest in plant-based diets in the health and fitness populations.

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 before/during/after working out.

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

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.

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 portion of the protein is isolated and thus, the end product contains even less fat and lactose.

This is a good mid-budget option for most people.

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 and purest 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 muscles with a quick amino acid boost.

Casein 

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) versus the 60 minutes of whey.

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

The amino acid flow is weaker but longer during casein digestion, making it an essential component of our pre-sleep meal, resulting in a powerful anti catabolic impact and improved sleep recovery.

Soy Proteins

This supplement has been the subject of much debate for a long time because it is thought to impact testosterone levels in males, according to some studies. 

We won’t go into detail because this is still a topic for study and research for a concrete conclusion.

Nevertheless, when the amino acid profiles of plants and animal proteins are examined, soy protein is the plant protein that comes closest to animal-source protein.

Soy protein is easily absorbed and can be an excellent supplement to your diet, particularly if you are a vegetarian.

Hemp Protein

Hemp, also known as cannabis sativa, is an excellent source of protein because it includes a complete set of amino acids in the proper ratios, including BCAAs and several essential amino acids.

Hemp is free of sugars, as well as saturated and trans fats, lactose, and gluten.

Hemp protein can also strengthen the immune system and metabolism while lowering harmful cholesterol and blood pressure.

Hemp is an excellent addition to your diet if you want to enhance your protein consumption because it is a completely natural product that is easily absorbed and high in antioxidants and enzymes.

Pea Protein

Pea protein powder is a supplement made by extracting protein from yellow peas.

It’s typically used to increase the protein content of smoothies and shakes and is a great fit for almost any diet since it’s naturally vegan and hypoallergenic.

Pea protein is a high-quality protein and a great source of iron. It can aid muscle growth, weight loss and heart health. It contains some of all 9 essential amino acids, although a little low in one of them. 

Note:

If you rely solely on plant protein (vegan and to some extent vegetarian), make sure that you vary your sources of protein to ensure you get enough of the 9 essential amino acids. 

Conclusion

The market offers a wide variety of options now when it comes to protein supplements and these are without a doubt viable additions to your nutrition plan.

To choose the best option for you, factor in the following:

  1. Type of diet you’re following (Are you plant-based or an omnivore?)
  2. Any present/past intolerances to any ingredients contained in the product
  3. Budget
  4. Taste – if it tastes bad, you won’t drink it! 

Based on these 4, you will be able to easily pick the best protein supplement for you, which will grant sustained protein intake at times of need, thus improving recovery and overall body composition in the long term.
