Know Your Whey Protein

by Jerry Teixeira March 24, 2014 0 Comments

With so many different types of proteins on the market, it can be hard to know what is the difference between two types of proteins, which protein is best for you and when you should consume your protein.

Since introducing Whey-Pro 5, I have received many questions about protein and more specifically the types of protein inside Whey-Pro 5. So, I’ve written up this article to discuss the differences and benefits for each of three whey protein types on the market and inside Whey-Pro 5.

Currently on the supplement market, there are three types of whey proteins; hydrolysed whey protein, whey concentrate protein and whey isolate protein.

All athletes alike, not just bodybuilders, need extra protein in their diets to counteract the damage that training can do to their muscles, to aid muscle regeneration/recovery and to boost muscle growth. Whey protein is often the protein powder of choice because the body can break it down and use it with ease.  Whey protein is a ‘fast protein’ and this means that it can be broken down, digested, absorbed and delivered to the working muscles; very quickly. Below are a few of the key benefits of Whey protein:

  • It increases glycogen stores in the muscle and in the liver
  • It contains cysteine, which is important in the breakdown of glutathione. Glutathione is a strong antioxidant, boosts immune function and aids muscle growth
  • Increased levels of glutathione have a strong correlation with an increase in peak power and improved work capacity up to 30 seconds
  • It can help to reduce % body fat while preserving and building lean body mass

Hydrolyzed Whey Protein (HWP)

Hydrolyzed whey protein is a variety of whey protein isolate, and this is marketed as being the highest quality of whey protein. Hydrolyzed proteins are partially broken down into peptides, which break apart the bonds that link them to the amino acids.  This creates pre-digesting peptides from the intact proteins. This creates the fastest absorbing whey protein of the three types of whey proteins, however, it's the most expensive of the three whey proteins and HWP is can taste bitter compared to concentrate and isolate whey proteins. Some manufacturers claim that HWP is digested quicker by the body post-exercise, then absorbed and used more efficiently by the skeletal muscle. HWP has a faster increase in blood amino acid concentration and higher insulin response when compared to ‘intact’ protein; post exercise. This process enhances their bioavailability, improves muscle protein synthesis and inhibits muscle degeneration. Other benefits of HWP include the following:

  • The large spike in blood amino acids and insulin caused by consuming HWP can happen without eating large amounts of carbs and increased calories. This is important for in helping to maintain lean muscle mass while trying to cut weight and general weight maintenance, as surplus carbs and calories unless used can be stored as body fat.
  • HWP makes you feel less bloated and you can consume a meal sooner and utilise the ‘anabolic window’ post exercise more effectively.
  • All of the potential allergens, like lactose, have been destroyed within HWP. This is good news for athletes who suffer from any of these allergies!

This type of protein is considered the fastest absorbing of the three whey proteins. However, it can be a lot more expensive than the isolate and concentrate whey proteins, which in their own right are also fast digesting proteins. Therefore, is the trade-off in taste and a massive increase in cost enough justified for the minimal digestion impact of the HWPs?  Many researchers believe that hydrolysed proteins are an excellent and quick form of digestible proteins, but so are the other protein types, which also have excellent amino acid profiles. That is why Whey-Pro 5 uses a blend of whey proteins, to bring our customers some of the benefits of the absorption of HWP while keeping costs down. 

Whey Concentrate Protein (WCP)

Whey concentrate protein is the most popular type of whey protein used in manufactured protein powers. It is less expensive to make compared to hydrolysed and isolate whey proteins because it only goes through the first stage of the protein creation process.

Many top bodybuilders and athletes consider this form of whey protein to be sub-standard, of a poorer quality and less effective when compared to the other two forms of whey proteins. The main reason why many sports performers feel that is of a lesser quality is that it contains more fats, carbohydrates and lactose along than the other two forms of whey protein.

However, many also like whey concentrate protein do to it’s more naturally and whole food substance, great taste and price. If you don’t mind a few additional grams of fats, carbs and you don’t have an issue with lactose, then this type of protein is the most economical option for you. Small amounts of whey concentrate protein are added to give Whey- Pro 5 a little more substance and taste without loading up on fats, carbs or lactose.

Whey Isolate Protein (WIP)

This type of whey protein is most commonly considered the standard in premiere sports protein powder and supplements. The ion exchange is a process that is used to concentrate the protein content in the powder. WIP has the purest constitution and contains the greatest amount of proteins to fat/carbs ratio and has been filtered to remove the lactose, creating one of the purest proteins available. WIP is considered to be in the middle between whey concentrate protein and Hydrolyzed whey protein in the amount of processing, speed of digestion and cost of protein. This form of protein is considered the standard for sports protein and the most abundant protein found in Whey-Pro 5.

Fundamentally, the big difference between whey isolate and hydrolysed whey protein is that the HWP has been put through the ‘hydrolyzation’ process. This does speed absorption of the protein, but also drastically, increases cost as well. This is why Whey-Pro 5 contains a blend of proteins, to give you a solid protein blend to help with your lean muscle recovery, maintenance and growth while keeping the cost reasonable.

With these fast absorbing whey proteins inside Whey-Pro 5, Whey-Pro 5 is designed to be consumed when you need protein fast. Although you can have Whey-Pro 5 anytime you like, the best time is between meal, before a workout or after a workout.

So, next time you go out to grabbing some protein is to ask yourself these two quick questions.

  1. What time of day am I planning to take this protein?
  1. Are the proteins inside the best types of proteins for when I plan to have this protein?

I hope this clears things up a bit and good luck! If you have any questions or suggestions be sure to leave a comment in the comment box.
