WPI or WPC Protein? What's the diff? Which is better? | SUPPLEMENTS
The main difference between a Whey Protein Isolate (WPI) and a Whey Protein Concentrate (WPC) is the protein content.
A WPC has a lower protein percentage. It can vary anywhere from 35-80% protein on average. WPCs are usually slower digesting and are great for cooking with.
WPIs are a more concentrated form of WPC, filtering out and isolating the protein component. They tend to have the highest protein content percentage, usually over 80%, and are usually also virtually lactose free. They tend to have lower carbs, thinner mix, and digests faster, making it perfect for after training.
So what is a whey protein blend?
Well, it’s simply a blend of both WPI and WPC. What you get out of it depends on the dominant protein in the blend, but are usually a medium cost per serve in comparison to a WPI (most expensive) and a WPC (least expensive whey blend).
