Blended Protein with Whey and Casein – Best in Test 2026! | Hardworkout Magazine

Key takeaways

- Blended protein powder combines whey and casein, so the whey triggers muscle protein synthesis quickly while the casein slows protein breakdown over several hours.

- Whey protein concentrate contains 70-80 % protein and retains some lactose and fat, while whey protein isolate contains around 85-90 % protein and costs more.

- Milk is made up of 80 % casein and 20 % whey, which is why many blended protein products contain more whey than casein.

- Micellar casein coagulates into a gel on contact with stomach acid and therefore releases amino acids more slowly than calcium and sodium caseinate.

- The test scores products on protein composition (40 points), carbohydrates (10), sugar (5), fat (5), taste (10), consistency and solubility (10), digestion and tolerance (10) and price (10).

We give you the overview of the best and most popular protein powders with blended protein in 2026!

What is blended protein, and who needs it?

Everyone who trains a lot and wants to build muscle needs extra protein. Protein powder is a convenient way to ensure sufficient protein intake throughout the day and is also of high nutritional quality.

[Studies](https://pubmed.ncbi.nlm.nih.gov/16937979/) have also shown that a protein powder with a blend of whey and casein, in combination with strength training, provides the greatest increase in lean mass.

You can read more about the different types of casein and whey protein at the bottom of this article.

How did we test the protein powders?

Hardworkout.no is committed to ensuring that the tests are independent and credible. We have focused on criteria such as ingredients/active substances, stated effects, documented effects, as well as studies and other documentation, to compile our top lists.

The products have been tested by evaluating nutritional content (protein composition, carbohydrates, sugar content, and fat), taste and consistency, tolerance, and price. We have tested one of the most common flavors for protein powder in this category, which is vanilla.

You can read more about the criteria for the blended protein test further down in the article.

PS: Prices and selection may vary from day to day. The prices we provide are recommended prices. Online stores often have good offers, and the products may be on sale at a lower price than what is stated here.

We always strive to keep the list updated with products that are in stock. Where there are multiple alternative prices, we link to several stores.

By shopping through the links in the test, you contribute to our ability to continue publishing quality-conscious tests and articles, and we greatly appreciate it if you do so. Prices are updated regularly and reflect the best prices on the market.

Criteria for the test

This list consists of protein powders with blended protein that we can recommend based on various criteria we consider most important when choosing the right protein powder:

Protein Composition (40)

We have assessed both the total amount of protein and which protein sources the product contains.

A higher proportion of whey protein isolate, micellar casein, and milk protein isolate results in a higher score.

Types of proteins assessed:

Whey protein concentrate, whey protein isolate, and whey protein hydrolysate. Micellar casein, calcium caseinate, sodium caseinate, and milk protein isolate.

Carbohydrate Content (10)

Protein powders with lower carbohydrate content score higher.

Sugar Content (5)

The protein powder received a higher score the less sugar it contained.

Fat Content (5)

The protein powder received a higher score the less fat it contained.

Taste (10)

We tested all products in one of the most popular flavors (vanilla).

Taste preferences are individual, but we emphasized that the protein powder should have a natural and good taste, without artificial or synthetic notes. Products with a pronounced aftertaste or excessive sweetness score lower.

The powder was tested in both water and milk to see if it made any difference in taste.

Consistency and Solubility (10)

Here we tested how easily the powder mixed into liquid, whether it easily formed clumps, and how much/less liquid we needed to achieve a good and creamy consistency for the shake.

We mixed it in both water and milk to see if it made any difference in consistency.

Digestion and Tolerance (10)

We assessed whether the product causes discomfort such as bloating or stomach issues with regular use. Individual tolerance will vary, and some may be more sensitive to lactose than others.

Price (10)

Price per kilogram is assessed in relation to protein source and protein content.

A product with a higher proportion of whey isolate or micellar casein will normally have a higher price than a product based on concentrate, and price is therefore assessed against content and quality.

Serving sizes vary between the different products.

Why are proteins important?

Proteins are made up of amino acids. In the body, we have 20 different amino acids, of which 8 (9 for infants) are essential, meaning that the body cannot produce them on its own and we must obtain them through our diet.

Amino acids have many important functions in the body and are crucial for building cells and tissues throughout the body, in the production of hormones and enzymes, and for the normal function of the immune system. Additionally, amino acids can be used as an extra energy reserve.

Proteins are stored as fat in the body if one consumes more than the body can absorb, and additionally is in a calorie surplus.

Proteins are important for muscle growth and are also important if you want to lose weight, as proteins keep you full longer and lead to fewer calories consumed.

Even though supplements should not replace regular food, protein powder is a good and inexpensive source of protein that can ensure adequate protein intake throughout the day.

Protein powder with whey

Whey protein is best known in various forms of Whey protein and is the most used on the market.

Whey is derived from cow's milk and is the surplus from cheese production and has high nutritional quality. Whey protein contains a large proportion of essential amino acids and is particularly rich in the amino acid Leucine, which in [studies](https://jn.nutrition.org/article/S0022-3166(22)08038-5/fulltext) has been shown to have a good anabolic (growth-promoting) effect.

Milk consists of 80% casein and 20% whey. To ensure muscle growth when strength training, it is important to add extra proteins through the diet.
