BPI Sports ISO HD

Bloating after a shake is common enough that plenty of people just put up with it. BPI Sports ISO HD takes a different route, pairing a high-grade isolate with enzymes that help you actually digest it.

The protein is whey isolate and hydrolysate, giving 25g per scoop for 130 calories with just 2g of sugar and 1.5g of fat - roughly 83 percent of the calories arriving as protein. Added digestive enzymes are there to reduce the heaviness that trips people up with dairy protein, and BPI Sports puts the product through third-party testing.

The 2.2KG tub gives 69 servings, which covers daily use across a long block.

It comes in Chocolate Brownie, a richer flavour than the standard chocolate most isolates default to.
