Whey Protein Isolate Vs Concentrate: What Are They

What is the Difference Between Whey Proteins?

Whey Protein Isolate and Concentrate are both made from whey, a thin high-protein liquid leftover from the process of converting milk into cheese.

The whey is processed into powder and will either be produced into an isolate or concentrate. What sets these two apart is how theyve been refined.

If youd like to learn more about what whey protein is before diving into a Whey Protein Isolate vs Concentrate comparison, you can find out all about it in this comprehensive article: What is Whey Protein?

Whey Protein Is Better Than Casein For Building Muscle

Whey protein is not only better suited for workouts because its quickly absorbed but also due to its amino acids profile.

It contains more of the branched-chain amino acids leucine, isoleucine and valine, while casein contains a higher portion of the amino acids histidine, methionine and phenylalanine .

While all essential amino acids are important for building muscle, leucine is the one that jumpstarts the process .

Owing in part to its higher leucine content, whey protein stimulates muscle protein synthesis the process by which muscles grow more than casein, especially when consumed in tandem with your workouts (

  • Iron: 4% of the RDI
  • Calcium: 50% of the RDI

Keep in mind that these nutrition facts may vary, depending on the specific product you buy, so be sure to read labels carefully.

Whats more, there are some other factors to consider:

  • Casein protein powder is generally more expensive than whey.
  • Whey protein powder tends to mix better than casein.
  • Whey protein powder often has a better consistency and taste than casein.

You can also buy protein blends, which typically contain a combination of casein and whey, giving you the benefits of each.

Alternatively, you can buy both powders individually and take whey protein powder with workouts, then casein before bed.

What Is Whey Protein Isolate

Whey protein isolate is an ultra-refined, high-quality protein produced from additional refining to ensure it maintains a rich nutrient profile with over 90% protein in every serving. Due to its unique filtration process, whey protein isolate is incredibly pure and contains little to no fats, cholesterol, carbohydrates, and lactose. Due to its negligible lactose amounts, whey protein isolate is a perfect choice for lactose-intolerant people.

Pea Protein Vs Whey Protein

Plant Protein Vs Whey Protein Which Is Best For Endurance

As most people know, protein is essential for building muscle and managing weight. Whey protein and pea protein are two of the most common types of protein supplements available in the market today — whey being animal based, pea being…well, pea-based.

That is, one comes from the meat production industry, and one from the plant kingdom. But with so many protein supplements available, it’s likely difficult to figure out which one best suits your needs and your lifestyle.

Thats where this little essay comes in. Let’s talk about the key differences between whey protein and pea protein, their amino acid profiles, and yes the comparative pros and cons of each protein powder type.

You Want A Leaner Body

If you primarily want to reduce fat reserves in your body, you should look into the issue of calorie intake. The problem with calorie reduction: It can have the consequence that fat-free body mass is also reduced. This means thatmuscle cells also , not just body fat.

EAAs are low in calories and at the same time prevent muscle breakdown, so fat is lost more effectively. One difference between the two amino acid sources is in the number of calories: Whey contains about 120 calories per serving, EAAs with 14 grams per serving only 50 calories. You can also support the supply of the muscles with Whey protein, but then you consume more calories, which requires more time for digestion and absorption into the muscle cells.

Whey Protein Isolate Vs Concentrate: Whats The Difference

The main difference between whey protein isolate and concentrate is the amounts of protein, fat, and lactose they have in them. Whey isolate contains a higher amount of protein and less fat and lactose than whey concentrate does. This makes it a great choice for people who want a more pure whey protein and also those looking for something low carb.

Your Body Absorbs Casein Protein Slower Than Whey

One of the significant differences between casein and whey protein is how quickly your body absorbs them.

Your body breaks down protein into many small molecules called amino acids, which circulate in your bloodstream until theyre absorbed.

Levels of these amino acids stay elevated in your blood for four to five hours after you consume casein but only 90 minutes after you consume whey .

This is because the two proteins digest at different rates.

As it does in cheesemaking, casein forms curds once exposed to the acids in your stomach. These curds lengthen your bodys digestion and absorption processes.

Therefore, casein protein provides your body with a slow, steady release of amino acids, making it ideal before fasting situations, such as sleep (

, 9).


Casein protein digests slowly while whey digests quickly. These differences in absorption rates make casein protein good before bed and whey protein ideal for around your workouts.

Whey vs Plant Protein: Is One Better Than The Other? | Nutritionist Explains | Myprotein

To best promote muscle growth, you should feed your muscles more protein than they need. Between whey and casein, whey is the “faster” protein supplement because its amino acids are absorbed quickly by your body. While casein is the “slower” supplement â since itâs digested more slowly â both proteins can help your muscles grow when you work out. Thatâs because they re-form fatigued muscles after exercise.

Regardless of which type you choose, the most important factor is how much total protein you eat throughout the day.

Whey Protein Isolate Vs Concentrate: What’s The Difference And Which One Should I Use

Many of us have heard of whey protein, but most people dont know the difference between the three main forms that are found in protein supplements: isolate, concentrate, and hydrolysate. When it comes to protein powder, the two most common forms of whey are concentrate and isolate. In this article, well look at what each form is and how to know which is right for you.

Pros And Cons Of Protein Shakes


  • Usually contains more protein per serving

  • Better choice for those who need an additional serving of protein with zero or minimal carbs and fats

  • A better ratio in the context of price per serving / amount of protein

  • Protein powder can mix with anything, giving you better control over the nutrient profile of your meals

  • Big variety of flavors

Could be improved:

  • Milk-based protein products can cause gastrointestinal disturbances due to the presence of lactose and / or difficulty digesting milk protein

  • Contain less fiber than bars

  • Less suitable for transportation, as a shaker takes up more space than a bar

What Is Isolate Protein

Isolate protein, or whey protein isolate , is a processed form of whey protein that does not contain fat and lactose. It contains 90% whey protein by weight. It is virtually carbohydrate-free, lactose-free, fat-free, and cholesterol-free. On the other hand, it contains the highest percentage of pure protein.

WPI production involves two methods: ion exchange method or membrane filtration method.

  • Ion exchange method it uses the surface charge characteristics of whey protein in the separation. Little alterations of pH make the attractions between protein molecules and molecules in the ion exchanger.

  • Membrane filtration it uses both microfiltration and ultrafiltration to separate whey protein based on the size of the protein molecules.

    Whey Protein vs Protein

    Proteins are one of the most abundant and useful macromolecules on earth. Protein function in living systems controls all the main mechanisms in them.


    Proteins are one of the most important types of macromolecules in living organisms. Proteins can be categorized as primary, secondary, tertiary and quaternary proteins depending on their structures. The sequence of amino acids in a protein is called a primary structure. When a large number of amino acids are joined together, the chain formed is known as a polypeptide. When polypeptide structures fold into random arrangements, they are known as secondary proteins. In tertiary structures proteins have a three dimensional structure. When few three dimensional protein moieties bound together, they form the quaternary proteins. The three dimensional structure of proteins depends on the hydrogen bonds, disulfide bonds, ionic bonds, hydrophobic interactions, and all the other intermolecular interactions within amino acids.

    Proteins are produced on ribosomes. Protein producing signal is passed onto the ribosome from the genes in DNA. The required amino acids can be from the diet or can be synthesized inside the cell. Protein denaturation results in the unfolding and disorganization of the proteins secondary and tertiary structures. This can be due to heat, organic solvents, strong acids and bases, detergents, mechanical forces, etc.

    What Is The Difference Between Whey Protein And Whey Protein Isolate

    The most significant difference between whey protein and whey protein isolate is the nutrient concentration. Whey protein isolate has high protein levels of over 90% and little fats, cholesterol, and calories. Whey protein concentrate has lower protein levels typically starting at 80%, and higher amounts of fat, lactose, and carbohydrates. The main difference between whey protein vs isolate is the amount of protein in every portion. Whey protein isolate provides a higher amount of protein per serving with little to no fats, carbohydrates, and sugar!

    Is There A Way To Use Both Pea And Whey At The Same Time Or Do They Need To Be Separate

    Yes, it is possible to use pea protein and whey protein together. In fact, combining the two can be beneficial in achieving your desired fitness goals.

    Pea protein is a plant-based source of protein that is high in fiber, antioxidants, and minerals such as iron, zinc, and magnesium. When using pea protein and whey protein together, its important to consider their individual characteristics and benefits. It’s also important to remember that plant-based proteins are a potent alternative to gas-causing whey protein, and pea protein — like whey protein — prominently features the branched chain amino acids that are the root of muscle mass building.

    Hydrolyzed Whey Protein vs. Whey Protein Isolate: Dave Palumbo Explains Difference

    Optimum Nutrition 100% Whey Gold Standard is a protein powder comprising mostly whey protein isolate. Each serving has 24 grams of protein.

    Whey protein isolate is a pure protein and helps to build muscle by delivering high-quality amino acids to muscle after a workout.

    This protein supplement also offers 5.5 grams of branched-chain amino acids. BCAAs help to deliver protein to the muscle at a faster rate and therefore improve recovery time after a workout. Protein has to be broken down into amino acids before it can be used by the body. They need to be broken down in the intestines, absorbed in the blood, and then travel to the liver to be changed into an energy source â this can be a lengthy process. BCAAs, however, can be used directly in the muscles for energy, and skip the processing to the liver, per the Encyclopedia of Human Nutrition .

    Optimum Nutrition whey nutrition facts vary according to the flavor you choose. The general nutritional profile for one scoop is 130 calories, 1.5 grams fat, 0.5 grams saturated fat, 5 grams carbohydrates, 0 grams fiber, 3 grams sugar and 24 grams of protein. This will fluctuate a minor amount according to flavor.

    Should I Have Whey Protein Isolate Or Concentrate

    Figuring out the best type of protein for you means looking at your body type, goals, fitness routine, and lifestyle. The ideal protein for you could be whey, but could also be a plant-based protein. That said, whey protein remains the most popular form of protein powder on the market, and its no surprise why. It has many proven benefits, and supplies a complete source of all nine essential amino acids. While both whey isolate and whey concentrate are fantastic protein sources, choosing the right one is important.

    If you are particularly sensitive to lactose, whey protein isolate is a great option. Whey isolate is so finely filtered that it has virtually no lactose. For those on a diet, whey protein isolate has slightly lower carbohydrate and fat content. On the other hand, if youre looking for the best tasting form of whey protein, whey concentrate is a safe bet. The added carbohydrates and fat in the more concentrated form of whey protein give it a more creamy, milk like flavor. Whey protein concentrate is often cheaper than isolate as well, but offers the same great benefits for muscle growth, maintenance, and overall recovery with the added perk of being packed with bioavailable peptides.

    Is Whey Or Plant Protein Absorbed Faster

    Generally speaking, whey protein is absorbed faster based on the FAO’s protein quality comparison.

    Soy Protein Vs Whey Protein

    Soy protein and whey protein are both dietary supplements that can help increase your total protein intake. While each form of protein has its own health benefits, for exercise, muscle building and weight loss purposes, research has shown that whey protein is superior. This is likely related to the amino acid profile and the fast absorption rate of whey protein.

    Effectiveness For Muscle Growth

    Whey Protein vs. Plant Protein: The Differences Explained

    To build muscle, you need to engage in strength training and consume enough protein that contains all essential amino acids and BCAAs.

    Whey protein isolate is considered the gold standard for muscle growth, as its a complete protein, contains a high amount of the BCAA leucine, and is absorbed the quickest .

    However, plant-based protein powders can also be complete proteins and contain high amounts of leucine, provided that they contain two or more plant proteins or are fortified with BCAAs (


    Both whey and plant-based protein powders are effective for building muscle. Ideally, opt for a protein powder that contains at least 20 grams of protein per serving.

    What Are Soy Protein & Whey Protein

    Soybeans are a type of legume that are naturally high in protein while remaining relatively low in fat. To create soy protein, manufacturers grind soybeans into a meal which contains no hulls or fat. This soybean meal is then processed into soy protein isolate, which consists of 90 to 95% protein . This soy protein isolate is then sold in powder form. The soy protein powder can be used to make a protein shake or to add protein to other meals. Although soy protein isolate is naturally high in protein but very low in carbohydrates, many manufacturers add additional nutrients to commercial soy protein to improve its taste, texture, and nutritional value.

    Whey protein, on the other hand, is made from cows milk. Cows milk naturally contains about 3.5% protein and 4% fat . After being pasteurized to kill any bacteria, special enzymes are added to the milk to separate casein — the milk solids that are used to make cheese — from the whey. This whey is processed further to remove carbohydrates, fats, and excess water. The end product is a protein-rich powder that can be used to make protein shakes.
