What is Whey Protein Isolate?

For anybody looking to build muscle, or simply help their muscles recover after a grueling workout, protein is absolutely vital, as it plays a crucial role in protein synthesis, which is where new muscle proteins are synthesized to replace damaged muscle tissue. As protein is vital for muscle growth and repair, protein supplements are the most popular sports supplements in the entire world, especially whey protein. Typically, whey protein concentrates are more common than isolates, because they are cheaper. Whey isolate and concentrates are both derived from cow’s milk and are obtained when the milk is separated into cheese. However, whereas whey concentrates will typically be between 70 and 80% protein per serving, whey isolates will be around 90-97% protein per serving. This means that you get more protein per serving, and less (only 5%) fats and carbohydrates, than regular whey protein. Whey isolate undergoes highly advanced filtration processes, which are typically micro and ultra-filtration processes. This means that the protein molecules do not become denatured, and so obviously, as a result, they are still as potent and effective. The proteins are high in bioactive peptides, and lactose, fats, carbohydrates, and other unwanted ingredients, are filtered out.

How does it work?

From a bodybuilding standpoint, whey protein is vital for a number of different reasons. To begin with, protein is actually thermogenic, which basically means that it increases the metabolism as the body attempts to digest it and break it down. This proves useful for weight loss and energy production. However, it really comes into its own when it comes to building muscle. As we exercise, especially with lifting weights, our muscle fibres and tissues become damaged, worn down, and even destroyed, which is why we feel sore after training. We don’t actually build muscle by lifting weights at all, we actually destroy it. We build muscle when we let our bodies recover, providing they have the right nutrients to do so. Protein is required for a process known as protein synthesis to occur, which, as mentioned, is when the body creates new muscle proteins and tissues to replace the damaged ones as a result of our workouts. Without the protein and amino acids making up the protein however, our bodies wouldn’t have the tools required to build the muscle. Whey isolate ensures that we get even more pure protein, so the muscles and muscle cells can absorb more nutrients required for optimal muscle growth.

What are the main benefits of whey protein isolate supplements?

Some of the primary benefits associated with whey protein isolate, include:

More protein per serving

As mentioned, whey concentrates are cheaper because they contain less protein, and provide less protein per serving. Typically, whey concentrates will provide around 70 – 80% protein, some more, and some even less. Whey isolates however, are typically 90-97% pure protein, so you get more protein per serving, and as a result, your muscles are being fed more nutrients per serving.

Muscle growth and repair

As we said, in order for the muscles to grow and recover following a workout, the body needs the tools required to initiate the post-workout recovery process. With whey isolate, that is exactly what the body gets, making it a fantastic supplement for helping to pack on the muscle.

Rapid Absorption

When it comes to post-workout nutrition, timing is everything, as you do not want to miss the ‘anabolic window’ so you need to get nutrients into your muscles as soon as possible. Whey protein in general, is fast absorbing, but as whey isolate contains less lactose, fats, and carbs, these cannot slow down absorption, so the protein gets into your system even quicker.

Other benefits include:

  • Increased muscle mass
  • Increased strength levels
  • Improved post-workout recovery
  • Great taste
  • High concentration of protein per serving
  • Convenient
  • Promotes athletic ability
  • Reduced DOMS after training
  • Helps strengthen the immune system
  • And more...

How and when should it be consumed?

Adults: 1 Scoop(s) 1 time(s) per day. Mix product well in 1-2 cups of liquid (water, juice, etc.) immediately before consumption. Store in a cool, dry place.

Whey Protein Isolate VS Whey Concentrate

Whereas whey protein concentrate is still very beneficial, it does only provide typically around 70 – 80% protein per serving, as opposed to whey isolate. Whey isolate is of a higher quality and is a much purer whey protein, making it more beneficial, which is why it does tend to cost slightly more. Whilst the benefits are largely the same, whey isolate is considered superior as it provides a much purer and much higher protein content per serving.

What can it be stacked with?

As it is a highly popular bodybuilding supplement, a great bodybuilding stack could be: Pre-Workout supplements, Creatine Monohydrate, L-Leucine, Waxy Maize Starch, and Casein Protein at night, all along with the whey protein isolate.
