Our verdicts
Zero Carb Whey Protein Isolate
Isopure Zero Carb does exactly what the name promises: 25 g of isolate protein with no carbs or sugar, plus a vitamin and mineral boost. It is a sensible pick for strict low-carb and keto eaters, but the lack of third-party certification, the artificial sweetener and a price well above rivals such as ISO100 keep it out of the top tier.

Clear Whey Isolate
Clear Whey Isolate is a smart option if milky shakes put you off: 20 g of certified whey protein in a light, juice-style drink for about 80 calories. Expect some foam and a learning curve with mixing, and sample flavors before buying the large tub, since taste reviews are genuinely split.
