Whey Protein Isolate

Whey protein isolate is whey that's been filtered further to remove more of the fat, carbohydrate and lactose. That leaves more protein in every scoop, usually 80–90%, compared with roughly 70–80% in a standard whey concentrate. Our range includes isolates, clear whey isolates and hydrolysed isolates from brands such as BioTechUSA, Weider, Trec Nutrition, Rule One, SciTec, Reflex Nutrition and Trained by JP.

Is whey isolate right for you?

Isolate is a good choice if you:

  • are cutting or counting calories and want the leanest protein shake
  • find standard whey heavy or bloating, as isolate is lower in lactose (though not lactose-free)
  • want a shake that's very low in sugar and fat

A popular example is BioTechUSA Iso Whey Zero, with 21g of protein and 93 calories per 25g scoop. If you'd rather have a creamier, cheaper everyday shake, a concentrate such as Skill Nutrition Whey may suit you better. Read whey isolate vs whey concentrate for a full comparison.
