Whey Protein Isolate

Whey Protein Isolate   

by Bulk Protein Powder

Whey Protein Isolate is Derived naturally from cow’s milk, Whey Protein isolate is a pure, rich source of essential Amino Acids - the building blocks required to produce lean muscle tissue. In its purest form as Whey Protein Isolate (WPI), it contains little to no fat, lactose or cholesterol. Whey protein isolate is Considered one of the most valuable sports supplements used by athletes and bodybuilders across the globe, Whey Protein isolate is essential to muscle repair, growth and strength.

The difference between Whey Protein Isolate and the alternate Whey Protein Concentrate (WPC) is that whey protein Isolate has a much higher pure protein content at about 87% plus. whey protein Concentrate supplements usually contain anywhere between 50% and 80% of protein and can incorporate a blend of Whey Protein Isolate and Whey Protein Concentrate. As the protein percentage decreases, the fat, lactose and cholesterol count actually increases, so for best quality always opt for a product with higher protein levels such as whey protein isolate.

whey protein isolate is Found naturally in foods such as beef, chicken, fish, eggs, milk and cheese, whey protein isolate is a vital element in everyone’s diet. While feeding the body sufficient amounts of protein is easy for the average person, bodybuilders and athletes in particular will find it hard to consume enough protein to maintain their physical lifestyles so that is when whey protein isolate can help.

Whey Protein Isolate is separated during the process of turning milk into cheese. In fact, before its benefits were realised, whey protein isolate used to be disposed as an unwanted by-product. There are two major methods for manufacturing Whey Protein Isolate; ion exchange filtration and ultra/micro filtration. Ion exchange filtration involves using hydrochloric acid and sodium hydroxide to separate proteins based on electrical charge. Due to the chemicals used in this process, some Amino Acids and nutrients can lose their value. However, this method does ensure that less fat and lactose are present in the final product being whey protein isolate.

As Whey Protein Isolate is derived from milk and made up of short chain peptides, the body can easily absorb feeding your muscles in as little as 15 minutes. In fact, Whey Protein Isolate has a more superior biological value (BV) than any other type of protein on the market. This means that whey protein isolate provides the largest useable amount of branched chain Amino Acids. 

Whey protein isolate also scores a whopping 1.14 on the Protein Digestibility Corrected Amino Acid Score and whey protein isolate is no less than a 3.2 on another measure being the Protein Efficiency Rating. Whey Protein Isolate's BV can reach a maximum of 157. Collectively these figures far surpass all other protein types. Due to whey protein isolates superior absorption qualities, Whey Protein Isolate is the perfect post-training supplement immedietely fueling muscles with vital recovery nutrients in this important nutrition window. Fats will slow the absorption of food but Whey Protein Isolate can counter this and aid in more efficient digestion. Further to this, the fact that Whey Protein Isolate contains little or no lactose means that lactose intolerant people can safely use it.

The benefits of Whey Protein Isolate do not end there. Studies have revealed a strong link to immune system protection and the ability to act as an Anti Oxidant – so much so that people with immune deficiencies have been known to supplement with whey protein isolate to increase Anti Oxidant levels. Whey Protein Isolate can also increase glutathione levels, which may lead to decreased chances of developing prostate cancer.

Whey Protein Isolate comes in powder form and is usually slightly more expensive than Whey Protein Concentrate due to its purity factor. It is essential that whey protein isolate is consumed daily, as the body cannot store it. An average daily intake calculation for adults is 0.8 to 1 gram of protein per kilogram. For example, a 100 kilogram man should consume between 80 and 100 grams per day. The average intake is higher though for athletes at 1.3 grams per kilogram and higher again for bodybuilders at 1.6 to 2 grams per kilogram. 

Whey Protein Isolate is a form of whey protein. Whey protein isolate is created as a by product of cheese production. Whey protein isolate is the best form of whey protein. whey protein isolate is similar to whey protein concentrate. whey protein isolate has a very low fat and carb level compared to the whey protein concentrate. Whey protein isolate is left over milk coagulates. whey protein isolate is not the only form of whey protein. there are actually 3 forms of whey protein. they are, whey protein isolate, whey protein concentrate and hydrolysed whey protein.

Whey Protein Isolate is a source of Branched Chain amino acids, which are used to fuel working muscles. whey protein isolate has high levels of BCAA's. Whey protein isolate is the best form of protein when it comes to adding lean muscle. whey protein isolate is used by bodybuilders and athletes of all types wanting to add extra muscle. whey protein isolate is also known as WPI, and is sold all over the world, whey protein isolate can be bought at health food shops or online for great prices. 

Difference Between Whey Protein isolate and Whey Protein Concentrate

for many years now people still are unsure what whey protein is better. althought whey protein isolate has more protein intake and less fat some people think whey protein concentrate is just as good. whey protein isolate is made up of over 90% of protein, less than 1g of fat and carbs while also having no lactose. whey protein concentrate is made up of less than 80% protein, with a higher level of fat and carbs, it also containes lactose. even though whey protein isolate may sound better thats not usually the case. most people seem to think whey protein isolate and whey protein concentrate are as good as each other. induviduals that use Whey protein isolate say its better due to having more protein with less fat and carbs. people that use whey protein concentrate push the fact that whey protein isolate is alot more expensive then whey protein concentrate, they also think that having that extra fat and carbs help you get big and strong.

 Most of the whey protein powders that you will find will contain a mixture of whey protein isolate and whey protein concentrate. Pure whey protein isolate and pure whey protein concentrate are the best, then you know exactly how much whey protein isolate or whey protein concentrate you are buying. when comparing both products whey protein isolate is more expensive then whey protein concentrate because its of higher quality meaning whey protein isolate is more pure and whey protein isolate has a higher biological value. Whey protein isolate contains more protein and less fat per serving. Usually Whey protein isolate contains 90-98% protein while whey protein concentrate contains only 70-85%.

As we all know whey protein isolate is the highest amount of protein avaiable, because of its properties whey protein isolate is also much easier to absorb into your muscle than what whey protein concentrate and hydrolysed whey protein's are. Obviously whey protein isolate would be the best protein to use due to its concentration, but like all great things there is a minus. whey protein isolate is much more expensive then whey protein concentrate. whey protein isolate might be more pure then whey protein concentrate but that doesnt mean whey protein isolate is going to give you more muscle and size.

Interesting Facts About Whey Protein Isolate

one thing that we can definetly say it better about whey protein isolate is, studies have shown whey protein isolate to have immune boosting properties. studies showed that whey protein isolate can significantly increase glutathione levels within the prostate epithelium. 

Is Whey Protein Isolate Suitable If You Are On A Diet

Whey protein isolate powder works great as part of a calorie controlled diet. Whey Protein isolate has the lowest fat content of any protein around. Almost all the fat content of milk is removed during the processing of whey protein isolate. Whey protein isolate can actually help you in your diet. When you have a carbohydrate heavy diet, your energy levels will peak and fall during the day giving you cravings. Using whey protein isolate can smooth out these peaks and troughs and stop your body craving fatty foods during the day.

How Can You Make Whey Protein Isolate Taste Better

Most people dont mind the taste of pure unflavoured whey protein isolate, but there are a few people out there that cant stand the taste of whey protein isolate and like to add there own flavor to it. If you are someone that doesnt like the taste of pure unflavoured whey protein isolate then i suggest mixing cocoa  powder or vanilla flavouring with the whey protein isolate giving it a delicious taste. Most people say that mixing there whey protein isolate with chocolate/cocoa is the best option. whey protein isolate mixed with chocolate does taste very nice, if your not a chocolate fan then you can also make a fruit smoothie. by blending the whey protein isolate with fruits of your choice you can get that great tasting whey protein isolate shake you wish for.

Whey Protein Isolate daily intake

Whey Protein isolate should be taken 2-3 times daily with each serve consisting of atleast 30g. whey protein isolate should be consumed evenly throughout the day giving your muscles the protein the require. induviduals should consume 1g of whey protein isolate per kilo of your bodyweight. for example if you weigh 90kg you should be taking around 90g of protein daily, remember if your a bodybuilder that should nearly be doubled. whey protein isolate should be taken with high protein foods, high protein foods can assist whey protein isolate giving you muscle size and strength.

When Should Whey Protein Isolate be taken

whey protein isolate should be taken immedietly upon waking, during sleep your muscles are starved from whey protein isolate so having a whey protein isolate shake when waking is a very important factor. the next important time to take whey protein isolate is after a workout, whey protein isolate should be taken immedietly after a hard workout, whey protein isolate will help rebuild your muscles after the rigors of your intense workout. The most important time to take whey protein isolate is before bed, studies have shown that 40% of muscle size increases during the sleep phase. that is why whey protein isolate should be taken along micellar casein before bed. due to whey protein isolate being a fast release protein micellar casein should be taken with the whey protein isolate so while your asleep the slow release proteins will last until morning. 

Whey Protein isolate VS Protein

Not all proteins are created equal. The source of a particular protein can make a large difference to its effectiveness and efficiency.

Protein Digestibility Corrected Amino Acid Score (PDCAAS)- The official method for measuring the quality of proteins in the Protein Digestibility Corrected Amino Acid Score (PDCAAS). This measures the amino acid profile of the protein against that require by humans and gives a score from 0 to 1. Whey protein isolate scores a perfect 1, meaning Whey protein isolate provides all the amino acids required by the body. This score makes whey protein isolate the best protein around.

Biological Value- The quality of a protein as determined by the PDCAAS is only part of the story. A protein may have all of the amino acids required but this is immaterial if the protein cannot be absorbed easily. Biological Value is a percentage score showing how much of the protein is absorbed by the body. Whey protein isolate, along with whey protein concentrate and whole egg protein, has a perfect score of 100.

Speed of Absorption- As well as the complete absorption level, it is important that the protein can be absorbed as fast as possible to aid recovery after training. Whey protein isolate and whey protein concentrate is digested exceptionally quickly which makes it ideal as a post-workout liquid meal.

Fat Levels- If you are on a low calorie diet, a protein’s level of fat will certainly be a consideration. The bigger of an issue this is for you, the more important the purity of the protein. Again, whey protein isolate ranks above any other protein in this area, whey protein isolate has the lowest fat level compared to whey protein isolate, hydrolysed whey protein and all other protein powders.

Taste- On a more practical level, different proteins have a different taste. This is obviously a matter of personal preference, but many people quite enjoy the mild, milky taste of whey protein isolate.

Should You Use Whey Protein Isolate Or Whey Protein Concentrate  

So if after reading this article you still cant decide if whey protein isolate or whey protein concentrate should be used then i suggest using whey protein isolate. even though whey protein isolate is more expensive, i believe that it is more beneficial than whey protein concentrate. the famous bodybuilder ronnie coleman once said "Never sell yourself short on protein, if you sell yourself short on protein dont expect to get any results".

Whey Protein Isolate Frequently Asked Question

What is whey protein isolate?

Whey protein isolate is a high quality whey protein powder from cow's milk. Whey protein isolate is more soluble than casein and also has a higher quality rating. It is often referred to as the "Gold Standard" of protein as it is the most nutritious protein available.

 How is whey protein made?

Whey protein isolate is a co-product of the cheese making process. Listed below is a brief description of the steps involved in making pure whey protein isolate.

1. Fresh milk is tested, approved by Quality Assurance experts and pasteurized.
2. The casein, or "curd", and a portion of the milk-fat are separated out to make cheese.
3. The remaining liquid whey goes through a series of fine, specialty filters to separate the whey protein from the lactose and other ingredients in the liquid whey.
4. Concentrated liquid whey enters an ion exchange tower to further concentrate and purify the whey protein. Ion exchange is a gentle process and does not denature, or "break down", the whey protein isolate.
5. Next, the product enters a drying tower to remove water.
6. The final step is to package the pure whey protein isolate powder into various size containers for use.

Is there a difference between whey protein concentrate and isolate?

Yes, there may be a large difference between whey protein isolate and whey protein concentrate. Whey protein isolate is the most pure and concentrated form of whey protein available. It contains 90% or more protein and very little (if any) fat and lactose. Whey protein concentrate has anywhere between 29% and 89% protein depending upon the product. As the protein level in whey protein concentrate decreases the amounts of fat and/or lactose usually increase.

Is whey protein isolate good for athletes and people who exercise?

 Whey protein isolate is a high quality, complete protein, with all the essential amino acids. Whey protein isolate is also the richest known source of naturally occurring branched chain amino acids (leucine, isoleucine and valine). These are important for active individuals, individuals who exercise and professional athletes. The body requires higher amounts of branched chain amino acids from whey protein isolate during and following exercise as they are taken up directly by the skeletal muscles versus first being metabolized through the liver, like other amino acids. Low BCAA levels in whey protein isolate contribute to fatigue and they should be replaced in one-hour or less following exercise or participation in a competitive event. Many athletes consume whey protein isolate both before and immediately after exercise or an event to help repair and rebuild lean muscle tissue.

 Is whey protein isolate compatible with a low-carbohydrate diet?

Yes. Whey protein isolate is not only compatible with low-carbohydrate diets it is an ideal choice. Be sure to select whey protein isolate which provides high quality protein without the carbohydrates and fat like in whey protein concentrate often limited in low carbohydrate diets.

Will whey protein isolate help me lose weight?

Adding whey protein isolate to the diet is a great way to jump-start a weight loss program. Whey protein isolate is a key ingredient in numerous weight loss and meal replacement products and whey protein isolate (with no fat or carbohydrates) is often the preferred choice. Studies have found that individuals who combine diets with leucine rich protein foods, like whey protein isolate, and exercise have more lean muscle tissue and they lose more body fat because of the impact of whey protein isolate. As they lose fat their metabolic rate increases and they naturally burn more calories each day. Another way that whey protein isolate helps manage weight is by promoting a feeling of fullness. One recent study showed that whey protein isolate was superior to casein, the other protein in cow's milk, in promoting satiety.

How does whey protein compare to other types of proteins?

whey Protein isolate foods are not equal and can vary in a number of ways including the following: Number and quantity of essential amino acids in whey protein isolate, Digestion and absorption rates, Fat content in whey isolate protein, Taste and Purity. Whey protein isolate is a very high quality complete protein with rich amounts of all the essential amino acids. Whey protein isolate is the purest form of whey protein, which is why whey protein isolate is absorbed so quickly and efficiently into the body.

How does whey protein compare to soy protein?

Here are some of the differences between whey protein isolate, whey protein concentrate and soy protein.

• Whey protein isolate is a nutritionally complete protein. It contains bioactive ingredients, like immunoglobulins and lactoferrin, that help support the immune system.
• Athletes prefer whey protein isolate to soy protein due to its rich abundance of branched chain amino acids and its quick absorption rate. These are important to help repair and rebuild muscles after a workout or competitive event.
• Whey protein isolate has a fresh, neutral taste compared and will not change the taste of foods you add it whey protein isolate.
• Whey protein isolate does not contain isoflavones or any other components with potential hormonal effects.

I eat a lot of fish, chicken, eggs, soy and beef. Why do I still need whey protein isolate?

Healthy diets should regularly include high quality, low fat sources of protein, like whey protein isolate. Calories do count and you want to make sure that you are getting the most benefit from the calories you consume. Compared to other proteins, on a gram-to-gram basis whey protein isolate delivers more essential amino acids to the body but without the fat or cholesterol. Nutrition experts recommend a diet with a variety of protein foods but for optimal results make sure that one of them is whey protein isolate.

Can I get enough whey protein by drinking milk?

 Milk is a highly nutritious beverage however, it only contains about 1% of whey protein isolate. In order to get all the benefits of whey protein isolate, you need to take a concentrated whey protein isolate powder like whey protein isolate.

Are all whey proteins the same?

No. There may be a major difference in the qualify of whey protein isolate based upon the following factors:

• whey protein isolate Source of Milk
• Whey protein isolate Production Method
• Whey protein isolate Type of Cheese Produced
• Whey protein isolate Individual Manufacturer Specifications
• Whey protein isolate Added Ingredients

What individual components are found in whey protein isolate?

Whey protein isolate is a combination of a number of individual protein components. In recent years new technology has allowed manufacturers to isolate and further purify many of these for use in new and exciting nutrition and oral care products.
