What Is The Difference Between Impact Whey & Impact Whey Isolate?


Impact Whey vs. Impact Whey Isolate


Whey protein contains protein, fat, carbs, vitamins and minerals. Due to its strong amino acid content and the ability to be absorbed by the body, it is ideal for building muscle. It has been shown to promote muscle protein synthesis, support fat burning, improve insulin sensitivity and suppress appetite. It has also been shown to increase the production of glutathione (antioxidant).

 

Protein powders are available in the form of whey concentrate or whey isolate. Both of these contain protein, however, isolate, which is made of whey concentrate, undergoes further processing to yield a product with a higher protein concentration.

What Is Whey Concentrate?

 

Whey protein is created when liquid portions of milk are pushed through a refined filter. The material that is then left behind and left to dry forms whey protein concentrate. This form of whey varies on the amount of fat and carbohydrates in the form of lactose.

 

The variation of protein can range between 30-80% and include numerous protein subtractions. According to evidence, these peptides need to remain in their natural, undenatured form to exert these properties.


What Is Whey Isolate?

 

While whey concentrate has the protein content of approximately 80%, the content within whey isolate is greater at 90%. This is due to cross-flow microfiltration, which causes the protein to separate from fat and lactose. Whey isolate is a common choice for those that are on low-fat diets as it is lower in fat compared to whey concentrate.

 

Whey isolate is also much lower in lactose, which makes it ideal for those with an intolerance. As whey concentrate is further processed and purified into whey protein isolate, the structure becomes degraded and loses some of its biological activity. However, the amino acid structure and sequence doesn’t change when the protein becomes denatured and will not affect the muscle building qualities. All large proteins are broken down during digestion into amino acids therefore whether this happens in the gut or in a manufacturing process it is irrelevant.

 

The choice of whey that you go for should depend on your goals, budget and allergies. As whey concentrate has a significantly higher amount of lactose, if you are lactose intolerant, it is beneficial for you to opt for the isolate. However, as there is much more processing to make isolate this makes it more expensive.
