Whey protein isolate contains a higher percentage of protein, and little or no lactose, carbohydrates, fats and cholesterol. Hence the “isolate” in the name. This form of whey protein supplement seeks to deliver optimal protein content for muscle development and recovery after physical activity.
Whey protein is also available as whey concentrate and whey hydrolysate. Whatever your choice, all of these proteins come from milk. When the liquid portion of milk (the whey) is separated from the other major components (the curd), the remaining liquid portion will contain a part of the proteins, fats, carbohydrates, vitamins and minerals.
At this stage, the whey is either dried and packaged, or further processed. How the milk is processed will determine the nutritional content. So, which form of whey protein is right for you? Look at our quick comparison below to see how they stack up.
- Concentrate – Think of this form of protein as a complete meal replacement. With these supplements, carbohydrates, fats, minerals, and other compounds make up a portion of the total contents of the supplement.
- Hydrolysate – These supplements contain predigested proteins, which means the long chain amino acids are broken down into single amino acids. This process mimics what occurs in our own digestive system. The only negative of this process is the loss of short chain amino acids and the added cost that comes from the additional processing.
- Isolate – This form of whey starts life as whey concentrate before undergoing further processing. As the whey structure continues to break down, smaller amino acid chains, known as peptides, can be lost, but its longer amino acid sequences remain unmodified. Also, more of the carbohydrates, fats and other nutrients are removed.
So, if you want a balanced protein supplement, then whey concentrate may provide the ideal nutritional content for your body. Isolate may be the right protein supplement if your diet provides the nutrients to meet your body’s dietary needs. Hydrolysate can be more expensive than isolate, but is believed to provide a more biologically active form of protein.

Whey Protein Isolate For Muscle Development
Protein from animal’s milk contains a complete source of branched chain amino acids that might not be present in some plant-based proteins. Amino acids are the building blocks of the body, and essential for the synthesis and utilization of protein in the body.
These amino acids also promote optimal bioavailability and absorption through the body, which may allow the proteins to be utilized when needed during and after the workout. While findings do show that whey protein isolate may provide advantages over comparable sources of protein, more clinical research is required to make a definitive statement.
While advantages over similar protein supplements aren’t entirely clear, whey protein isolate is still ideal for individuals that want to reduce their intake of fat, carbohydrates and other nutrients.
