What is whey protein?
This watery substance contains fast-digesting, high-quality whey proteins.
What are whey protein isolate and concentrate?
Whey protein isolate is made by removing fats, carbohydrates, and other nutrients from whey protein.
Whey protein concentrate is similar, but it’s less highly processed.
“Concentrates are the most basic form of protein supplement.
Similarities:
Both are made from milk protein.
They’re not suitable for vegans, who will want to look forplant-derived protein powdersinstead.
They’re easily digestible.
They’re complete proteins.
This is important because humans must acquireessential amino acids5through diet since our bodies don’t produce enough.
Both are beneficial for training adaptations from exercise.
Summary
Differences:
Concentrate is more affordable.
Whey protein isolate is considered a more premium product.
It tends to be more costly since it undergoes a longer manufacturing process, resulting in higher protein content.
“Generally, isolates are more expensive since they have a higher protein concentration,” says Church.
Isolate has a higher protein concentration.
As mentioned above, whey protein isolates have higher protein content than concentrate.
Typically, whey protein isolate contains 90 to 95% protein, while concentrate contains 70 to 80%.
Concentrate has a higher lactose content.
Since whey protein isolate is more processed, it contains less lactose and fewer carbohydrates and fats.
Concentrate is more satiating.
Is one better?
So which is better, isolate or concentrate?
Both are readily absorbable, easy to digest, and good for boosting physical performance.
- Ultimately, the answer boils down to individual needs, how they’re used, and personal preferences.
Your health and fitness goals might also impact which one you choose.
“Find a whey protein with all the essential amino acids in the required range,” adds Church.
Ideally, the product should provide20 to 30 grams of protein per serving7with2.5-3 grams of leucine for optimal MPS8.

Both will help you optimize physical performance andbuild muscle.
Also, isolate tends to be more expensive, which may be a deterrent for beginners.
Are there any whey protein isolate side effects?
Whey protein isolate is safe to consume.
However, it should be taken in conjunction with a regular exercise routine that includesstrength training.
The takeaway
Whey protein is a fast-digesting, easily absorbed dietary protein supplement.
The two most common forms are whey protein and isolate.
Both are beneficial for recovery and physical performance but differ in protein concentration and how they’re processed.
