Whey Protein Isolate vs Whey Protein Concentrate

Milk protein is comprised of casein and whey. Casein is unsuitable for many due to digestion issues, whereas whey protein, with heavily reduced fats and lactose, is generally more tolerated. Whey protein is the richest natural source of the essential building blocks for muscles, branched-chain amino acids (BCAAs). It is a complete protein in that it contains all 20 amino acids, unlike many other proteins such as soy. Look at the table below and find out which one is for you.

In More Detail



How is it made? Bare Blends unique Native WPI is produced directly from skim milk via a chemical and heat free micro filtration process, rather than the double pasteurized byproduct of the cheese making industry. Bare Blends’ Whey Protein Concentrate (WPC) is produced as a liquid by-product of cheese making process in the chemical and pesticide-free grazing hills of New Zealand.
What is it?
  • Bare Blends’ premium Native Whey Protein Isolate (WPI) is a high-protein filtered milk product containing very little lactose, fats, and carbohydrates.
  • Unlike other whey proteins, it is processed directly from milk and is NOT a byproduct of the cheese making industry.
  • It has a higher concentration of amino acids and less calories than WPC.
  • WPC is the closest to the natural form of whey. It contains small amounts of fats and carbohydrates, and has a higher lactose content than WPI.
  • It is a complete protein in that it contains all 20 amino acids, unlike many other proteins such as rice and soy.
  • Much of the natural amino acid profile and immune boosting factions retained in WPC are typically lost in other whey proteins.
