What Is The Difference Between Isolate Protein And Whey Protein

What Is Whey Concentrate

What is the Difference Between Whey Proteins?

Whey protein is created when liquid portions of milk are pushed through a refined filter. The material that is then left behind and left to dry forms whey protein concentrate. This form of whey varies on the amount of fat and carbohydrates in the form of lactose.

The variation of protein can range between 30-80% and include numerous protein subfractions. According to evidence, these peptides need to remain in their natural, undenatured form to exert these properties.

% Isolate Is Ideal For You If

You are lactose intolerant/have significant issues digesting whey concentrate.

If so, chances are youre going to have issues with many whey protein powders that contain any amount of concentrate due again to the lactose it contains.

So for example, if youve noticed that you get bloated and/or find yourself greatly exceeding your average daily FPD , and you suspect that your whey protein might be the cause you may very well be correct.

The first option in these cases is to just try some other brand. Yes, even if it still contains some amount of concentrate. Ive personally noticed big differences just from one brand to the next despite the fact that it was a similar form of whey .

But if every concentrate-containing protein powder you try causes digestive issues for you, the simple solution would be to switch to a powder that is comprised entirely of whey protein isolate.

It will be more expensive because of the fancy filtration process it goes through to become isolate, but its that process that removes virtually everything from the protein , thus making it a much purer and lactose-free form of whey.

Which in turn usually eliminates all of the digestive issues.

If youd like a recommendation, this is the only 100% isolate Ive ever tried, and its probably the purest there is: NOW Foods Whey Protein Isolate

Impact Whey Protein Blend

The Whey Protein Blend is a very simple and basic whey protein. The protein blend itself is 80% protein per serving, and has minimal additional ingredients.

Impact Whey Protein Blend has these ingredients:

  • Artificial sweeteners
  • Xantham gum

Some of the flavors also have a small amount of salt or coloring in them.

The presence of the artificial sweeteners sucralose and acesulfame K might alarm some people.

There isnt conclusive evidence that these ingredients affect human health, especially in the low amounts used.

Additionally, Labdoor finds Impact Whey Protein Blend has below the accepted amount of heavy metals in the protein itself .

Taste & Mixability

The flavors vary from the typical cookies and cream to strawberry. Theres also an unflavored option for those who cant eat artificial sweeteners or dont like the taste.

The best flavor weve tried so far is the chocolate .

It mixes well in water or different milks . But it can clump faster than wed like if you dont mix it fast.

Nutritional Content

The Whey Protein Blend is low in fat and carbs, but does have some of both.

Heres the rundown:

  • 4g Carbohydrates
  • 21g Protein

For a typical gym goer these are great nutritional numbers. For a advanced level or elite bodybuilder, you may want something with more protein, or less carbs and fat depending on your current goals.

Whey Protein Isolate Vs Concentrate Both Help Fat Loss

Protein is a valuable macronutrient for weight loss. Unlike carbohydrates, protein has no effect on blood glucose and insulin levels. Increased blood glucose from consuming refined sugars and simple carbohydrates can increase body cat accumulation.

That being said, whey isolate does contain fewer calories, carbohydrates, and fat per serving than whey concentrate. A common misconception when it comes to weight loss, is that you should cut calories and eat less, forcing yourself into a caloric deficit in order to burn body fat. The ladder of that statement, is in fact true. You do need to be in a caloric deficit in order to lose weight. However, more often than not, under-eating will cause your body to store more body fat and slow down metabolism, resulting in sub-optimal results, and can lead to further frustration.

One of the most crucial elements to losing weight, is making sure you’re eating enough. That includes protein. It may sound counterintuitive, that you need to eat more to lose weight. But i assure you, it’s not.

A study published in Obesity Surgery examined the effect of whey protein supplementation on weight loss and body composition of women who regained weight after bariatric surgery. Patients recieved 0.5kg of protein per pound of body weight for 16 weeks accounting for a 75% increase in total protein intake. Participants who supplemented with whey protein, as opposed to placebo, significantly reduced total body weight and fat free mass .

Both Help Build Muscle

If your end goal is to build muscle mass, its important to pay close attention to the quality of the protein you consume on a daily basis especially in the 2-3 hours before and after your gym session.

For the body to utilize protein, the small intestine must break down and absorb the protein and transport the resulting peptides and free amino acids to the blood, where they can then circulate to the various tissues in the body. Some protein sources are difficult for the body to break down.

Therefore, it’s important to select a rapid-digestingprotein source before and after your workout. This allows you to maximize protein synthesis, which builds muscle and encourages fat loss.

Whey proteins solubility allows it to be absorbed immediately after it is ingested. The result is a spike in amino acid levels, leading to muscle protein synthesis.

Research by Nutrition and Metabolism shows that individuals who consume 20-25 grams of fast-digesting protein , may see an increase in muscle building through the process of muscle protein synthesis. This is true in the post-workout window and up to 48 hours after an intense resistance training session.

In addition to digesting very quickly, whey protein is especially high in the amino acidleucine, which helps to promote muscle-protein-synthesis and aids recovery. Whey protein has much higher leucine content than other forms of protein, including casein, making it ideal for those trying to pack on muscle mass.

Protein Isolate Vs Concentrate

Youll find many types of proteinincluding milk, soy, rice, egg, and peamost of which are available in both concentrate and isolate form. By far the most commonly used protein supplement is whey protein, and in particular whey protein concentrate. The differences between whey protein isolate vs. concentrate also apply to other types of protein, so well focus on these two forms of whey.

Whey Vs Beef Protein In Summary

Whey Protein Isolate vs. Concentrate: What’s the Difference?
  • Beef protein is a good choice for paleo athletes and those with dairy or whey sensitivities.
  • Beef protein contains unique amino acids, which lack in the modern-day diet such as proline, glycine, hydroxyproline, and arginine.
  • Limited studies suggest that beef protein can help build more mass, strength. A massive body of evidence supports and proves that whey protein improves strength, helps build more muscle mass, optimizes body composition, and improves workout recovery.
  • Beef protein is not a complete source of protein, and lacks substantial concentration of essential amino acids, needed for muscle protein synthesis. Whey protein contains 34.96 grams vs. 19.4 grams in beef protein isolate of essential and branched chain amino acids per 100 g serving
  • Beef protein has a low digestibility score, with an average of 0.30 compared to a score of 1 for whey protein.
  • Beef protein has a saltier, gamier taste, when compared to whey protein
  • Beef protein does not mix as well as whey protein

Differences Between Whey Protein Isolate And Whey Protein Concentrate

The main difference between these whey protein supplements is nutritional because whey protein isolate goes through a slightly different manufacturing process. The whey is isolated from the carbohydrates and fats, making it lower in carbs and lactose but higher in pure protein. Whey protein concentrate contains the same essential amino acids theres just a slightly higher serving of carbohydrates and fats.

If youre limiting dairy products or youre lactose intolerant, whey isolate may be easier to digest.

Why Not Combine Them Into A Blend

That’s actually a great idea, and fortunately, brands are already leveraging blended proteins that utilize both fast and slow-digesting proteins. You get all the benefits when you combine various protein sources, which makes blends a viable option for your needs.

Both whey protein and casein protein are complete protein supplements. Yet, bodybuilders and fitness enthusiasts use them for different purposes. Whey offers fast recovery while casein has a sustained muscle synthesis property. Ideally, incorporating both protein types into your daily regimen will help provide you with some great results.

Evidence Based

Whey Protein Concentrate and Whey Protein Isolate are the undisputed kings of the protein world, with each having their own benefits depending on your physique goals. So, which is best and which is the right choice for you?

There are two main differences when it comes to the concentrate vs isolate debate, even though both proteins are derived from the same raw ingredient, milk.

Put simply, both these proteins go through a filtration process, with isolate being subject to a more intense process. This allows isolate to be lower in calories, carbohydrates and fats than concentrate while maintaining its high protein contents.

It also has a lower lactose content too, so is the preferred protein for those who avoid dairy products. However, this doesnt mean that concentrate isnt the right choice for you. Whey Protein Concentrate is also low in fats, carbs and calories and contains a pure protein content and usually has a lower price. In this article we cover all areas of these two beasts, so you can make an informed decision of which is best for you.

Whey Protein Concentrate Vs Isolate: How To Read The Nutritional Label

The global protein powder market is expected to reach $32.6 billion by 2027. Due to the sheer number of whey protein powders on the market, you need to do your research to ensure you purchase a high-quality product.

All whey protein supplements are not created equal. As a general rule, the shorter the ingredient list and the easier those ingredients are to pronounce the better the product.

In addition, to ensure you’re consuming protein and no fillers or preservatives, calculate the “P/Cal” of a product. For example, if a supplement contains 32 grams of protein and 310 calories per serving, the P/Cal is 41%. In other words, 59% of the protein powder could be made from maltodextrin or other fillers.

If you see two protein powders on the shelf, one with a P/Cal of 41% and the other with 90%, choose the one with the higher protein-to-calorie ratio. As a good rule of thumb, it’s best to find a supplement with a P/Cal over 80%.

Why Does Whey Protein Isolate Cost More

Although WPC is a high-quality protein, it does and should cost less than whey protein isolate. When it comes to protein powders, the amino acids make up the majority of the costs to the manufacturer, where the other macronutrients and micro-nutrients are considered negligible.

Whey protein concentrate costs less to make than whey protein isolate because it contains less protein, and if you have noticed, all tub protein supplements are sold by weight, not by total grams of protein. Whey protein is most commonly sold in pouches or tubs by the pound or kilogram. If you compare a single pound of WPC with WPI gram for gram, you’ll find less total protein grams in the WPC thus, you are buying less protein and should then , pay less for it.

Isolate protein not only contains more protein than the same tub filled with WPC, but it spends more time in the processing plant recycling through the microfilters resulting in a purity that yields a light, fluffy, dense protein powder of 90-95% potency. In summary, Whey protein isolate costs more to make than whey protein concentrate because you get more grams of protein per package, and it requires the manufacturer more time to prepare.

What Are The Types Of Whey Protein

Whey Protein – Concentrate vs. Isolate vs. Hydrolysate

There are three primary types of whey protein: whey protein concentrate , whey protein isolate , and whey protein hydrolysate .

Here is how they differ:

  • Whey protein concentrate with low levels of fat, lactose and carbohydrates the amount of protein you receive will depend on how concentrated WPC is. Lower concentrates have around 30% protein, whilst higher concentrations can have as much as 90% protein. Typically, WPC has around 70-80% protein, and of the three has the best flavor.
  • Whey protein isolate this type of whey protein is further processed to eliminate all fats and lactose from the equation. As a result, WPI usually has at least 90% protein if not more. Yet there is a downside to all this processing it will have lost most of its beneficial nutrients.
  • Whey protein hydrolysate this is a pre-digested form of whey protein, as it has already undergone hydrolysis . This means WPH needs less digesting than the others and is quicker to be absorbed. And this makes WPH a great addition to medical protein supplements, as its improved digestibility and reduced allergen risks, makes it suitable for even infants. WPH can also cause a 28-43% higher spike in insulin than isolate.

Which is best?

When you compare the stats, whey protein concentrate can offer you the strongest results. Not only is it the cheapest, but it retains most of the beneficial nutrients found in whey. Its taste isnt too bad either, as it contains more lactose and fat than the others.

Should You Take Whey Or Isolate After A Workout

Containing nine essential amino acids, whey is considered a complete protein that helps to promote the growth of lean muscle mass. Whey is the fast-digesting part of dairy protein casein digests at a much slower rate and is, therefore, best for promoting satiety that’s easily absorbed by the gut and distributed for use by the muscles, per U.S. Dairy.

Whey isolate protein helps to prevent the breakdown of muscle tissue that can occur during recovery from a workout. Muscle growth occurs as a result of the body’s repair of minute tears in muscle fibers following a workout. Most Americans get adequate dietary protein and don’t require supplementation but athletes, bodybuilders and people in training for endurance events or seeking to improve their ratio of muscle to fat can benefit from supplemental protein.

Consuming a whey isolate protein drink following a workout preserves muscle and aids in recovery. In a 10-week study of recreational bodybuilders, a group given whey isolate made greater improvements in strength, increased lean mass and reduced fat mass compared to a group given casein, researchers reported in an October 2006 study in the International Journal of Sports Nutrition and Exercise Metabolism.

In its powdered state, whey protein powder isn’t vulnerable to spoiling, so you can carry it along in a shaker bottle to the gym or for an outdoor workout, and add water when you’re ready to drink it.
