Protein Powders And Protein Processing
There are several types of protein powders: whey, egg, pea, hemp, casein, brown rice and mixed-plant proteins with 3 common forms of processing:
Protein Concentrates Taken from whole foods, such as animals or vegetables, where heat, acid or enzymes are used to extract the protein. This can supply up to 80% protein with what remains comprised of fat and carbohydrates.
Protein Isolates This is where the processing goes through more concentration, thereby isolating the protein even further from the non-protein nutrition such as fat and carbs. This can supply up to 95% of protein.
Protein Hydrolysates Takes a concentrate or isolate and goes through even more processing, maximising the protein and the speed of its absorption.
Difference In Raw And Processed Protein
The difference in raw proteins compared to heavily processed proteins, is that raw proteins are not heated above 118f . Most processed proteins are cooked at high temperatures, or require additional acids and enzymes to break down the protein more acutely, whereby giving it a higher concentrated protein content. This will suit those looking to gain muscle-mass quickly, but not necessarily your strict raw vegan.
On the other hand, despite generally having a lower percentage of protein, sources of raw protein maintain nutritional benefits, including fats, fibre, vitamins and amino acids, which would be otherwise removed during the concentration process.
So, all in all, it is dependent on your goal and choice of lifestyle. If you want fast results in muscle-gain, go processed, if you want a natural, healthier balance of pure protein with other nutritional advantages, choose raw.
The Whey Protein Guide: Whey Isolate Vs Concentrate Vs Hydrolysate
When choosing their post workout shakes, people almost unanimously agree that whey protein is best for recovery and having optimal potential for muscle gain. The reason is that whey is a complete protein and one of the most natural sources of protein available on earth. Therefore, it has the highest percentage of branched-chain amino acids or BCAAs that the body cant produce on its own, including leucine, which plays the biggest part in muscle protein synthesis.
While it is common knowledge that Whey Protein is the best when it comes to recovery and muscle building, less known are the differences between each type of Whey Protein out there. Finding out what are these differences can help you identify which one will better fulfil your needs.

Protein And Athletic Performance
The primary role of dietary proteins is for use in the various anabolic processes of the body. As a result, many athletes and coaches are under the belief that high intensity training creates a greater protein requirement. This stems from the notion that if more protein or amino acids were available to the exercising muscle it would enhance protein synthesis. Research has tended to support this hypothesis. Within four weeks of protein supplementation in subjects resistance training, significantly greater gains were seen in protein synthesis and body mass in the group of subjects with the greater protein intake . Similarly, Lemon et al. also reported a greater protein synthesis in novice resistance trained individuals with protein intakes of 2.62 versus 0.99 g·kg-1·day-1. In studies examining strength-trained individuals, higher protein intakes have generally been shown to have a positive effect on muscle protein synthesis and size gains . Tarnapolsky and colleagues have shown that for strength trained individuals to maintain a positive nitrogen balance they need to consume a protein intake equivalent to 1.8 g·kg-1·day-1. This is consistent with other studies showing that protein intakes between 1.4 2.4 g·kg-1·day-1 will maintain a positive nitrogen balance in resistance trained athletes . As a result, recommendations for strength/power athletes protein intake are generally suggested to be between 1.4 – 1.8 g·kg-1·day-1.
Protein Intake And Metabolic Disease Risk
One of the major concerns for individuals on high protein, low carbohydrate diets is the potential for the development of metabolic ketosis. As carbohydrate stores are reduced the body relies more upon fat as its primary energy source. The greater amount of free fatty acids that are utilized by the liver for energy will result in a greater production and release of ketone bodies in the circulation. This will increase the risk for metabolic acidosis and can potentially lead to a coma and death. A recent multi-site clinical study examined the effects of low-carbohydrate, high protein diets and reported significant elevation in ketone bodies during the first three months of the study. However, as the study duration continued the percentage of subjects with positive urinary ketone concentrations became reduced, and by six months urinary ketones were not present in any of the subjects.

Benefits Of Whey Isolate
Whey protein vs. isolate isnt an easy choice, but isolate has some definite advantages. These include:
- Less fat & carbs. If youre on a strict diet, isolate is a good choice. It allows you better control over your fat & carb intake.
- A higher proportion of protein. Isolate typically contains more protein per 100g than concentrate, which is preferable for intensive trainers.
- Better for lactose intolerance. As the active element gets isolated from other dairy-based elements, this kind of powder is better for lactose intolerant individuals.
- Reasonably priced. While more expensive than concentrate, isolate isnt too costly and gives you a lot for your money.
Hydrolyzed Whey Protein Isolate
ON, Dymatize and Labrada are some of the companies that continue this process even further, which means whey protein isolate is converted to whey protein hydrolyzate. This occurs as a result of enzymes acting on whey protein isolate that break the bonds that hold amino acids together. Basically, this means that amino acids are cut into smaller pieces, shorter chains of di- and tripeptides, which causes the hydrolyzed whey protein to release the fastest and easiest protein to digest.
Basically, it is a pre-digestion process that causes hydrolyzed proteins to be absorbed faster in the intestines and at a much faster rate, followed by whey protein isolates and concentrates. Plus, its easier to digest than people with sensitive stomachs.

Whey Vs Isolate Protein The Difference Between Isolate Protein And Whey
Protein is an essential nutrient for building muscle mass, yet many people dont know much about which is better, whey protein vs. isolate whey protein. Many bodybuilders make this mistake and by ingesting too many calories without making the necessary adjustments. You want to consume low-calorie meals to ensure your muscles dont get too tired and starving them may cause them to shrink. This article will explain why whey protein is more beneficial than isolate and give you tips on what type of meal to have.
Protein is excellent for everyone. Bodybuilders will undoubtedly need it, but so will recreational skiers, runners, and weightlifters. Its also suitable for those who suffer from allergies or sensitive skin. It is beneficial because it provides all the amino acids and essential fatty acids your body needs in a simple form.
Isolate protein vs. whey protein can often seem like two different options that arent that different. But they are very much the same thing. Most bodybuilders supplement their diets with whey because its easily digested by the body and provides an excellent source of protein. Even for athletes, isolate protein is still a great option because it helps replace the naturally excreted nutrients in the urine.
Whey Protein Isolate Vs Concentrate
The main difference between whey protein isolate and whey protein concentrate is protein content.
Whey protein concentrate is the most common form of whey protein. To understand how whey protein concentrate is processed, imagine whey falling off a conveyor belt into buckets. All you need to do is filter out impurities, dehydrate it, flavor it, and call it “Delicious Chocolate Whey Concentrate.” Some supplement companies may do more than that to their concentrate products, but it’s not required.
That means whey protein concentrate can vary widely in terms of protein content. Whey protein may be labeled as “concentrate” if 25 to 80 percent of its content by weight is protein. So if you scoop out 100 grams of protein powder, it can be called whey protein concentrate if anywhere between 25 and 80 grams of that is protein.
Whey protein isolate, on the other hand, must be at least 90 percent protein by weight. If you scoop out 100 grams of whey isolate, you will get 90 grams or more of protein a significant difference compared to concentrate.

Whey Protein Concentrate Nutritional Facts
When whey protein is removed from milk and microfiltered, it retains a very high percentage of protein, and depending on which protein concentrate you buy, the percentage can range from 30% at the bottom of the quality spectrum to 80% at the top quality end.
Most companies usually use 80%, so you know you are getting the most out of every sip. Although it maintains a very high protein content, it is also very low in carbohydrates and low in fat. As an example, see below for nutrients for the flavored Chocolate Whey Protein.

How To Choose Between Casein Protein And Whey Protein
Both the casein protein and whey protein supplements are a powerful source of protein. So, how should you determine which one of the two is the best protein supplement? Due to the difference in the level of various amino acids, both have their own unique advantages.
Strength and Muscle
Whey protein is rich in branched-chain amino acids and has a high biological utilization rate. BCAAs are responsible for enhancing muscle protein synthesis. Researchers compared the rate of muscle protein synthesis with whey protein, casein protein, and milk protein. The study concluded that whey protein was fast, the milk protein intermediate, and casein protein was slow in the initial peak time to synthesize muscle protein.
Weight Loss and Lean Muscle Mass
Both whey protein and casein protein promote weight loss and improve lean muscle mass. While both whey protein and casein protein can help keep you full, being that casein protein is a much slower digesting protein, it can help keep you satiated longer, which makes it a great option at night as well as between meals if needed.
The rise of the amino acid level in plasma after the ingestion of whey protein is fast and high, while it is slow with casein protein. A study indicates that although whey protein initiates the rapid synthesis of protein, a major part of this protein is used by the body. In contrast, the protein synthesized through casein accumulates in the body over a longer duration.
Benefits Of Whey Hydrolysate
- Good for lactose intolerance. As the enzymes used in hydrolyzation break down milk proteins, you dont need to worry about your stomach struggling to digest them.
- High level of protein. Hydrolysate contains a very high proportion of protein, making it highly effective for building muscle.
- Great for recovery. Athletes find that hydrolysate helps to improve recovery after exercise better than other protein powders.
What Is The Difference Between Whey Protein And Raw Whey Protein
Raw whey protein is when the whey is separated from the solids. Fat and Lactose are not removed, and artificial flavourings are not added. This means there is a lower amount of protein, however, beneficial nutrients encouraging muscle growth are still included which would otherwise be missing in Whey Protein Isolate. This is due to Raw Whey Protein not being heated during the process of its preparation, so the protein you receive remains in its purest form.
The lactose in whey is broken down by our digestive enzyme, lactase. For obvious reasons, whey protein is not suited to everyone. Obvious factors, of course, being anyone with a lactose intolerance or allergy. Alongside this, as we get older, it can become increasingly more difficult for our bodies to create lactase, resulting in the protein not being absorbed properly, which can cause abdominal discomfort.
Furthermore, whey is less environmentally friendly and sustainable due to its very essence being taken from milk. There are many other protein powders available which do not involve animal products and are vegan friendly.

Milk Protein Vs Whey Protein What’s The Difference
Protein supplements are an integral part of a bodybuilding regimen. It is also used to improve stamina and performance. With many types of protein supplements available on the market, it is tough to choose between them. When picking a protein supplement that perfectly fits your specific needs and requirements, you should have a basic knowledge about the various sources and what benefits you can expect. In this article, we will discuss milk protein and whey protein to allow you the ability to choose which one you would prefer to use and when to help you achieve your health and fitness goals.
Amino Acids In Protein Powders
When protein products start touting how much of a certain amino acid they have added or that they have a better amino acid profile, ignore the hype. It doesn’t matter. The amino acid profile becomes important when you are comparing different protein sources. And since both casein and whey are milk-derived, they have essentially the same amino acid profile.

Why Is This Important In Whey Concentrate Vs Isolate
As whey concentrate is further processed and purified into whey protein isolate,3 these 3-d structures can degraded and lose their biologic activity. You should note, however, that the amino acid sequences do not change when protein is denatured, and whether a protein is denatured during processing does not affect its muscle-building qualities. All large proteins are broken down during digestion into smaller protein chains and individual amino acids , and whether this process occurs in the gut or in the manufacturing plant is irrelevant to the muscle fibers getting these proteins.
However, since denaturing can affect the biologic activity of certain peptides, whey concentrate has a theoretical health advantage over isolate. That being said, depending on the process used, whey isolate may still have significant amounts of bioactive peptides. Ion-exchange is a purification process that, while producing the highest concentration of protein, essentially eliminates all bioactive compounds. Micro-filtration techniques, such as Cross Flow Micro filtration, are a more expensive procedure but yield a whey isolate with more intact bioactive peptides. Hydrolyzed whey isolate is whey isolate that has been further broken down, yielding small peptides that are rapidly absorbed into the blood stream. Again, though, this extra processing comes at the cost of destruction of health promoting substances.
Isolate Vs Whey Protein
The difference between isolate and whey protein is that isolates are whey that is processed further to reduce the lipid and lactose content leaving only the protein isolate. Whereas the whey differs from the formula. They possess a different portion of lactose in them, depending on the usage guidelines.
Isolates are most commonly preferred by people with varying nutritional requirements. As a small chunk of the population does have a food sensitivity and tolerance level for lactose sugar, isolates come in handy to serve its need. People who have lactose intolerance can certainly consume isolates.
Whey protein in general is used for making various nutritional supplements such as energy bars and protein shakes. Interestingly people have even started using whey protein powder to incorporate in their daily diet with different dessert recipes such as cookies and pancakes.
