Whey Protein Isolate

(73 products)

Whey protein isolate is the most filtered form of whey — more protein per scoop, less lactose, less fat — which is why it's the powder we recommend most often on the shop floor. This collection covers Canadian favourites like Limitless Pharma Whey Protein Isolate, PVL IsoGold, Perfect Sports Diesel New Zealand Whey Isolate, Allmax Isoflex, and Beyond Yourself Isolate, plus ready-to-drink options like Ryse Clear Whey and CBUM RAW isolate shakes. Orders over $100 ship free anywhere in Canada from our BC warehouses.

How much of each scoop is protein, from the labels. Flavours can differ slightly, so check the label of the one you pick. For cost per 25 g of protein, see our whey protein isolate buying guide.

Whey Protein Isolate FAQ & Buying Guide

Which whey isolate should I choose?

If you want value per serving, the 5 lb tubs of Limitless Pharma or Beyond Yourself Isolate are hard to beat. PVL IsoGold and Allmax Isoflex are long-running Canadian favourites, and Perfect Sports Diesel uses New Zealand-sourced whey. For something lighter, Ryse Clear Whey drinks like juice rather than a milkshake.

When is the best time to take whey isolate?

Any time that helps you reach your daily protein target — post-workout is popular because isolate digests quickly, but a scoop at breakfast or between meals works just as well for supporting muscle repair and maintenance.

How does whey isolate compare to regular whey protein?

Isolate goes through extra filtration, so it's typically 85–90% protein with minimal lactose and fat. Regular whey concentrate is cheaper but slightly lower in protein and higher in lactose. If dairy tends to bother your stomach, isolate is usually the better-tolerated option.

Is whey isolate good for cutting?

It's a popular choice when calories are tight, since you get more protein for fewer calories per scoop, which helps you maintain muscle while eating in a deficit.
