WPC vs WPC Comparison Chart
This is in fact a common question asked by many experienced or beginning exercise enthusiasts looking to supplement with whey protein.
It may even make you scratch your head as to why whey protein isolate carries a higher price tag, which we cover in greater detail here.
Let’s dive in.
What is Whey Protein?
Are you familiar with the process of making cheese? No? Well, imagine you are.
When cheese is pressed through one of its many cheese-making stages, the liquid by-product strained from the cheese is called whey.
This whey is then dehydrated into a fine powder through low-temperature, ultra-filtration processes, which protects the protein content and retains nutrients.
Whey Protein Concentrate
Whey Protein Concentrate (WPC) is the cheaper of the two, containing 80-85% of protein content, and the rest containing carbohydrates and fats.
WPC generally has a better flavour profile due to the higher carb and fat content, although due to the presence of lactose, makes it unsuitable for lactose intolerant individuals.
For lactose intolerance, WPI is generally the recommended option.
Whey Protein Isolate
Whey Protein Isolate (WPI) is the expensive counterpart of the two, containing approximately 90% protein content, and the rest being trace carbohydrates and fats.
WPI is generally more expensive due to the extra filtration it goes through during the manufacturing process.
This extra filtration process makes WPI extremely low in lactose, and is generally recommended for individuals with lactose intolerance.
Fun fact: Designer Physique WPI contains less than 1% lactose!
