Whey Protein Isolate Questions

Grams of Protein per serving

November 20, 2015

So I was reading the label on one of the sample packs they sent and on the label is says 25g of protein but then towards the bottom it says 28.19g of whey isolate. What caused the loss of protein or is the 28.19 the actual amount?

The 28.19g of WPI contains whole food factors other than strictly protein. If you add up the amount of carbs, fat, and other micronutrients, it will equal 28.19g. The fat, carbs, calcium, cholesterol, phosphorus, potassium, etc. are all contained in the whey protein isolate, they are not additives.

It seems odd because unfortunately Nutrabio is one of the few companies to be so clear with their labels. If every company did it that way, you may find an even bigger discrepancy between the amount of whey, and the actual protein content.

Most isolates are usually only 90% protein - thus the 28.19 turns into 25.3g protein. The difference is mostly lactose (milk sugar) and counted as fat and carb.
