Protein Isolate

Guides and comparisons How to compare whey protein products

Whey protein isolate powders in many flavours, including clear isolates that mix into a light, juice-like drink. Isolate is whey filtered further than a concentrate to a higher share of protein; the nutrition table shows what that means for each product in protein, carbohydrate, fat and lactose per 100 g. Compare the protein per serving together with the scoop size in grams, and the price per kilogram of protein rather than per tub. Blends of isolate with whey concentrate or egg protein list each protein on the ingredient list.

Frequently asked questions

What is the difference between whey isolate and whey concentrate?

Both come from milk whey. An isolate is filtered further, which raises its share of protein and lowers the share of other milk components such as lactose and fat. How large the difference is depends on the product, so compare the protein, carbohydrate and fat per 100 g in the nutrition tables.

Is whey isolate lactose-free?

Not automatically. Filtering removes most of the lactose, but an isolate can still contain some. If you need to avoid lactose, check the nutrition table and the label of the exact product for a lactose statement.

What is clear whey isolate?

A whey isolate made to mix with water into a clear, light drink instead of a milky shake. Clear isolates are usually fruit-flavoured; compare their protein per serving and per 100 g like any other isolate.
