A source of protein and other essential nutrients, whey protein is the preferred supplement for athletes and gym-goers. However, despite its properties and benefits being widely known, few people know the differences between the types of whey available on the market.

Each supplement has different characteristics. Both are made from the same raw material (whey protein), but the difference is the manufacturing process, filtering and possible additions. Therefore, choosing the most suitable supplement should be based on each person's personal needs, metabolism, goals and pathologies.

But what types of whey are there, after all? That’s what we’ll show you in this article. Continue reading until the end and see the main options that can contribute to your muscle mass gain, weight loss or nutritional intake. We’ll also show you how to choose the right whey to get the best results. Follow along!

Types of whey protein

Generally speaking, there are three types of whey protein: isolate, hydrolysate and concentrate. As we explained earlier, supplements vary according to the production method and the amount of proteins, fats and carbohydrates. The raw material, however, remains the same.

Before showing the characteristics of each one, it is important to understand that the more filtered it is, the greater the biological value of the whey. And the smaller its particle, the better and faster its absorption will be.

Isolated

Whey protein isolate is the most concentrated in protein content, containing around 90% of this nutrient alone, the result of a rigorous filtering process that eliminates much of the lactose, carbohydrates, fat and minerals, leaving it practically “pure” protein.

During the filtration process, the molecules are broken down into smaller particles, which means they are absorbed more quickly into the body. For this reason, it should be consumed as soon as you wake up and after exercising. After consuming it, your muscles will be receiving the desired nutritional supply within a maximum of 40 minutes.

The fact that the supplement “isolates” elements such as lactose, fats and carbohydrates makes it suitable for people who are sensitive to the sugar present in milk and for those who practice physical activities with the aim of gaining muscle mass.

Concentrated

Unlike the previous option, whey concentrate undergoes fewer filtering processes, which results in “coarser” protein molecules that take longer to be absorbed. It also contains fat and lactose, so it is not recommended for people who are intolerant to milk sugar or have allergies.

In general, the protein concentration of this type of supplement is around 70% to 80%. This is a lower amount than the isolate, but it is still a great source of supplementation. For diets that reduce calories and increase muscle mass, it is a great option. Since digestion occurs slowly, the body remains nourished for a longer period of time, which makes it ideal for consumption both pre- and post-workout.

Among the three types of whey, concentrate offers the best value for money on the market.

Hydrolyzed

Also known as WPH, hydrolyzed whey is best and fastest absorbed by the body. This is because it undergoes hydrolysis, a process that breaks down protein molecules into even smaller particles and makes digestion even easier.

This procedure is also responsible for leaving the supplement with low levels of carbohydrates, fats and lactose. Therefore, it is a great option for those who are allergic or intolerant to the sugar present in milk and for those who need fast muscle recovery after more intense workouts. Just like whey protein isolate, the percentage of protein in this type of supplement is high and can reach up to 95%. Therefore, among the three, it is the one with the highest value on the market.

And vegan whey protein, does it exist?

Whey protein, no, but vegan protein supplements, yes. It may not seem like it, but there is a difference between these types of products.

When we talk about whey, we associate it with whey protein, therefore, it is a product of animal origin. Vegan supplements, on the other hand, are made from vegetable protein. Typically, three main bases are used to make them: soy, rice and pea. Some brands choose just one of these to produce it, while others opt for all three and use them in a blend.

The vegetables present in the product undergo several filtering processes so that the protein molecules are isolated in each grain. As a result, we have a supplement with a high quantity of amino acids and other nutrients, all of plant origin. And best of all, it is low in fat and carbohydrates, so it can be consumed by people who are allergic to gluten or lactose.

Efficiency of vegan supplement compared to whey protein

Many people wonder whether vegan supplements are as effective as whey protein isolate, concentrate, and hydrolysate. Some say that plant-based protein products perform less well than animal-based products, but there are studies that show otherwise, such as the one published in the Nutrition Journal. In this study, researchers evaluated the effects of whey protein and plant-based protein supplements on the body composition of individuals undergoing strength training.

At the end of the investigation, after eight weeks, they concluded that both groups increased muscle mass and reduced body fat without showing significant differences between those who used whey and those who used rice protein.

So, if you take a plant-based protein supplement, don't worry! Your performance in training and results can be satisfactory, just like those who use a milk protein product. Just remember that to achieve your goals, you need to combine supplementation with a balanced diet and regular training. That way, you'll go far!

What is the best whey protein?

There is no way to say for sure which whey protein is the best among the options. As we have shown, each one has different characteristics that benefit people with different goals, metabolisms and needs.

The concentrated supplement, for example, offers a lower protein content and a slower absorption process than other types. In addition, it has a high concentration of lactose, fats and carbohydrates, which makes it no longer an interesting option for people who are allergic to lactose and gluten. The isolated supplement, on the other hand, has a greater quantity of amino acids and a faster digestion capacity, which is why it is recommended for athletes with low, medium and high intensity training.

Finally, we have hydrolyzed whey protein which, due to its high protein content, can be recommended for people who need rapid muscle repair and for those who have problems with poor digestion and intolerances to substances present in greater quantities in other supplements.

Therefore, the best whey will be the one with properties capable of supplying your nutritional deficiencies and intolerances. It is important that the whey chosen helps you obtain the best results in your workouts, according to your goals.

How to choose the right whey protein for you

To choose the right supplement for your profile, you must first evaluate your goals, needs and personal characteristics. The next steps, however, can be based on the following tips.

Count on the guidance of an expert

Consulting a qualified professional is essential. They will assess your health, goals and needs and then recommend the most suitable product for you. And no, don't think about taking whey on your own, even if you know where it comes from. Otherwise, it may not provide what you really need and the effects will not be interesting.

Furthermore, have you ever imagined developing a reaction due to consuming a supplement that is not suitable for your body? It is not worth the risk.

Avoid products with lots of additives

To find out which whey protein is best for you, it is very important to pay attention to the chemical composition of the product. The fewer additives you see on the label, the better. Colorings, flavorings, aromas and preservatives are some ingredients that you should avoid, especially in large quantities.

As we taught in this other article , labels are organized by the proportions of ingredients, from largest to smallest. The earlier these elements appear, the more additives the supplement contains. Keep this in mind when choosing yours.

Choose a flavor that you like

Strawberry, chocolate and vanilla are among the traditional whey protein flavors, but there are many others on the market. So, to make this moment of taking care of your body even more enjoyable, choose the tastiest option for you. This is a way to consume the product without much effort.

Invest in a good cost-benefit

When choosing a supplement based on your preferences and needs, there is no doubt that price is something to consider. There are whey products with very high prices that are not always worth the investment. In this case, the cheapest or most expensive, in most cases, are not a sign of quality.

It is very important to pay attention to other details that really make a difference. You can look for user feedback, research the raw material and check the recommendations from professionals who monitor your health. This way, you will make a good investment and have a great return.

See? Finding the right supplement doesn’t have to be an impossible task. Just consider your goals, needs, and personal tastes to choose the best one for you. Following all the tips given throughout the text also makes a big difference. Just apply them when you go shopping. This will make the decision even easier.
