What is Whey protein, the Benefits & why is our IsoBlend protein sooo good?

Here we explain what whey protein is, what the benefits are when using it alongside training and we also introduce our new whey IsoBlend!




Whey is a by-product of cheese and yoghurt production. When cheese and milk are produced, the liquid residue left behind is the source of whey and another form of  protein called casein.

The whey is suspended in the liquid along with other materials. This has to then be separated from the liquid by filtering and then heating processes to extract the Whey Isolate.

Whey protein is one of the biggest sources of food protein available today and is considered to be the most nutritional valuable protein available.

Whey protein is also considered a complete protein as it contains all 9 essential amino acids. A large proportion of our cells, muscles, and tissue are made up of amino acids, meaning they carry out many important bodily functions. Including muscle development and maintenance.

This is why whey protein has a huge presence in nutritional markets for sports supplementation, as supplementing your training alongside consuming a good quality whey protein can help improve muscle protein synthesis and promote the growth of lean tissue mass.

We do usually get an intake of protein via our diets, however, when training it is very beneficial to supplement the diet with the extra proteins that we require due to the breakdown of muscle fibers.  This will aid muscle recovery and growth. Trying to consume the levels of protein that you require through diet alone can be both difficult and expensive, therefore Whey protein powders can be a very useful tool to boost protein intake. 


There are two forms of whey protein

Whey protein concentrate (WPC)

 WPC is processed in a cheap and cost-effective manner. In this process, some of the carbohydrates and fats remain. This form of whey is used in the majority of protein-based products due to the lower cost of producing it, and as a result, people using these products may experience minor weight gain. As the filtration and separation process is relatively simplified, more of the lactose (sugars) in WPC remain, which is why it is not suitable for people who are lactose intolerant. 

Whey Protein Isolate (WPI)

WPI is produced by refining the cheese making by-product. This is done with microfiltration, and heat treatment to further separate the whey from the undesired fats, carbs, cholesterol and lactose. WPI is less common in sports supplements as it requires more costly manufacturing processes. Due to the optimum quality of isolate, it means it is far easier to absorb within the body and is an option to consider for people who are lactose intolerant 

More about Whey IsoBlend by Grilla Fitness

Whey IsoBlend has been created for those who take their training seriously and require only the highest of quality proteins for recovery and muscle development. 

IsoBlend contains approximately 83% of protein per serving, of which approximately 50% is in isolated form, which means it is ideal for fast absorption and is extremely low in calories and carbs. Due to the low lactose content  it could potentially be an ideal solution for those who are lactose intolerant. 

To further promote the health benefits of our IsoBlend, we have incorporated a number of digestive enzymes with the following benefits

  • Alpha-amylase: Helps by starting the digestion process by breaking down carbohydrates
  • Neutral protease: breaks down many forms of proteins which mean it is absorbed more efficiently within the body
  • Lactase: Used to aid persons with intolerance’s to lactose, assisting the digestion of dairy products
  • Lipase: Is key for the digestion of fats which some say can also promote weight loss. Other benefits include lessening the symptoms of IBS and boosting nutrient absorption.
  • Cellulase: Helps with the digestion of plants and vegetables


Grilla Fitness IsoBlend comes in four great flavors, Strawberry Swirl, Vanilla Ice Cream, Chocolate Chunk and for something a little different Milk bottles! We have ensured with our flavorings that you will enjoy the experience of drinking them as well as the physical benefits!

Who is it for?

Those who wish to increase strength, gain muscle, aid effective muscle repair and lose body fat.

If you require only the best of supplements to complement your training and fitness regime, why not give our IsoBlend a try!
