Whey Isolate

Whey isolate is whey protein further filtered to remove fat, lactose and carbs, usually 85–90% protein or more — the best choice when cutting or if you are lactose-sensitive.

It mixes easily, absorbs quickly and is low in calories. 25–30 g after training is typical. When choosing, check the protein percentage per serving and that there is no amino spiking (inflating protein with added amino acids).
