Isolate vs Whey Protein

The difference between isolate and whey protein is that isolates are whey that is processed further to reduce the lipid (i.e., fat) and lactose content leaving only the protein isolate. Whereas the whey differs from the formula. They possess a different portion of lactose in them, depending on the usage guidelines.

Isolate vs Whey Protein

As a small chunk of the population does have a food sensitivity and tolerance level for lactose sugar, isolates come in handy to serve its need.

Interestingly people have even started using whey protein powder to incorporate in their daily diet with different dessert recipes such as cookies and pancakes.

Comparison Table

Parameters of ComparisonIsolateWhey Protein
CompositionIsolates contain 90% protein and about 5.5% water.Commonly, around 25g of protein per one heaping scoop. Possess around 30-80% protein.
Protein percentageRelatively higher than whey protein, around 90% or more percent by weight.80% protein by weight.
UsageIdeal for calorie deficit diet plans.Ideal for muscle building.
Carbohydrate & fat levelsCarbs and fat content are lower than whey protein.It contains a significant amount of carb and fat.
AbsorptionContains minimal lactose, hence easily digested and absorbed by the body.Contains lactose and fats, thus requires more time to absorb.  

What is Isolate?

Whey protein isolates are a more processed or concentrated version of whey.

The whey protein is concentrated through further microfiltration and then ultra-filtered to remove the lactose content and carbohydrates present in the whey protein to make it easy to adsorb.

The lactose content is as least as 0.8g per 100g of isolate, thus making it a perfect source of protein to moderate lactose intolerants.

The taste of isolate is usually flavorless if it is not processed with flavors thus it is usually tasteless in its original state. The isolates are recommended to be consumed within an hour to terminate the dispersion of protein in the beverage.

It also consists of a very negligible amount of cholesterol, fat, and lactose. Some companies later add lactase which helps in faster digestion and adsorption.

What is Whey Protein?

Whey proteins or concentrates come under the primary step of purification. It contains a negligible amount of protein when compared to that of isolate.

This water undergoes further purification processes to pasteurize the liquid whey to kill the bacteria and other microbes present in it.

Whey protein possesses certainly a lot of benefits including protein provision, it also provides various healing properties, nutritional supplements, and weight gain.

There are researches available that claim that whey protein could help in increasing immunity in children suffering from asthma.

Main Differences Between Isolate and Whey Protein

  1. Whey protein may contain some traces of cholesterol and lactose.
  2. Whey and isolates both can be consumed in moderations to lose weight, to quench the protein requirement.
