Protein powder protein quality, simply explained.
A protein powder with 24 g of protein per serving looks straightforward at first glance.
Many buyers mainly compare:
✓ Protein per serving
✓ Price per container
✓ Taste
But this is precisely where a common misconception arises:
The amount of protein alone says little about the actual protein quality.
Because for muscle building, muscle maintenance, and regeneration, it's not just about how much protein is included – but also which amino acids the protein provides.
| Factor | Protein A | Protein B |
|---|---|---|
| Protein | 24 g | 24 g |
| Leucine | 2.0 g | 3.8 g |
| EAA | 8.6 g | 11.5 g |
Amino Acids: The Real Quality Behind a Protein Powder
Proteins are made up of amino acids.
Particularly important are the essential amino acids (EAAs) – these are amino acids that the body cannot produce on its own.
For muscle building and muscle protein synthesis, the following amino acids play a central role:
- Leucine
- Isoleucine
- Valine
- Lysine
- Methionine
- Threonine
- Tryptophan
Therefore, two protein powders can have the same protein content yet still provide significantly different functional quality.
You can find more about the role of leucine in our article on Leucine & Muscle Building.
Why Leucine Is More Than Just an Amino Acid
Leucine is one of the most well-known BCAA amino acids and is considered an important trigger of muscle protein synthesis in the context of muscle building.
The crucial point:
Not every protein delivers the same amount of leucine.
For example, a protein shake with 24 g of protein can contain around 1.5-2 g of leucine.
Another product with the same 24 g of protein may deliver 3-4 g of leucine.
Yet, the label still states the same "24 g of protein."
This difference can be particularly relevant for the following target groups:
✓ Strength training
✓ Muscle building
✓ People aged 50 and over
✓ Vegan diet
✓ Few protein-rich meals per day
Vegan Proteins: Why the Amino Acid Profile Becomes Particularly Important
Plant-based proteins sometimes differ more significantly in their amino acid profile than classic dairy proteins.
Relevant differences often concern:
✓ Leucine
✓ Methionine
✓ Essential amino acids (EAA)
✓ BCAA profile
Therefore, with vegan protein, it's worth looking beyond the pure gram count.
If you want to compare different protein sources, you'll find suitable vegan protein powders or light alternatives like Clear Vegan Protein.
Protein Quality per Serving: An Often Underestimated Metric
Many buyers primarily focus on:
Price per container.
However, a often more useful question is:
How much functional protein quality does one serving actually deliver?
This includes, for example:
✓ Leucine per serving
✓ Total EAA amount
✓ BCAA profile
✓ Protein density
✓ Serving efficiency
Especially for protein-conscious nutrition, muscle building, or healthy aging, the quality per serving can be more indicative than just the gram amount.

Protein Requirements from 50: Why Quality Can Become Even More Important
As we age, the body's response to protein changes.
Therefore, aspects such as:
✓ Protein quality
✓ Amino acid profile
✓ Leucine supply
gain additional importance for many people.

Whey or Vegan – Which Protein Source Is Right for You?
The right choice heavily depends on individual goals.
Many pay attention to:
- Tolerability
- Ingredient list
- Amino acid profile
- Dietary habits
- Taste
- Sweetening concept
If you want to compare different options, our overview provides suitable protein powders in Switzerland as well as specialized Whey Protein and vegan protein powders, and for each product, tables with nutritional values and amino acid profiles.

Conclusion: Not Every Protein with the Same Gram Amount Delivers the Same Protein Performance
24 g of protein are not automatically 24 g of the same protein quality.
Those who consciously choose protein powders should also consider:
✓ Amino acid profile
✓ Leucine content
✓ Essential amino acids (EAA)
✓ Protein source
✓ Tolerability
✓ Ingredient quality
Because ultimately, it's not just about how much protein is in the shake – but also what protein quality actually arrives. You can also compare our entire protein powder Switzerland range.
We deliberately use protein powders without artificial sweeteners such as sucralose, aspartame or acesulfame-K and use natural ingredients and transparently disclose all ingredients and the amino acid profile.
