What is Whey Protein Isolate?

Whey protein isolate is a highly refined form of whey protein. It has a high protein content and low amounts of fat, lactose, and carbs. This makes it a top pick for fitness lovers and active people who want a quality protein that helps with muscle growth and recovery.

Whey protein comes from cow’s milk and includes proteins like Beta-lactoglobulin and Alpha-lactalbumin³. Making whey protein involves separating the solid curds from the whey during cheese making³.

Whey protein can be turned into concentrate, isolate, or hydrolysate³. Whey protein isolate gets more processing to remove fat, lactose, and carbs. This results in a powder that’s 90-95% protein⁴. Whey protein concentrate, on the other hand, has 30-80% protein, depending on the product⁴.

Whey isolate has less than 1 gram of carbs and about 110 calories per serving, making it a leaner protein option⁴. It’s also absorbed quickly by the body. This makes it a great choice for post-workout recovery and muscle growth⁴.

Whey concentrate is cheaper, costing about $1.60 per 100 grams. Whey isolate is pricier at around $3 per 100 grams because of its complex manufacturing process⁴. Yet, its high protein and low fat, lactose, and carbs make it a favorite for those seeking a refined protein supplement⁴³.

Characteristic	Whey Protein Concentrate	Whey Protein Isolate
Protein Content	30-80%	90-95%
Carbohydrates	2g or more per serving	Less than 1g per serving
Calories	Approximately 120 calories per 30g	Approximately 110 calories per 30g
Absorption Rate	Slower	Faster
Cost	Around $1.60 per 100g	Around $3 per 100g

In summary, whey protein isolate is a refined and concentrated whey protein type. It offers high protein, low fat, lactose, and carbs, and quick absorption. Even though it costs more than whey concentrate, its nutritional and performance benefits make it a top choice for health-focused consumers and athletes⁴³.
