Whey Protein Isolate
Whey protein isolate goes through an extra filtration step that strips out most of the fat, carbs and lactose found in standard whey protein concentrate. The result is a powder that typically sits above 90% protein by weight, compared to 70 to 80% for concentrate. That means more protein per scoop and fewer calories from everything else.
Choose isolate over concentrate if you’re in a cutting phase and need to keep calories tight, if you’re tracking macros closely and want a cleaner protein source, or if lactose gives you issues. Isolate contains significantly less lactose than concentrate. If budget matters most and you’re not fussed about the extra few grams of fat and carbs, a budget protein will do the job at a lower cost per tub.
When comparing isolates, look at protein per serving rather than tub weight. A 2kg bag with 25g protein per 30g scoop gives you better value than a 1kg bag with the same spec. Price per serving is the real comparison metric, and every product on this page shows it. If you want something lighter and juice-style rather than a creamy shake, clear whey uses the same isolate base in a different format. For a protein that supports a calorie deficit with added ingredients, diet whey blends isolate with extras like green tea extract and CLA.
