Which is cheaper, Isopure or MyProtein?

MyProtein is significantly cheaper, especially during the brand's frequent 35 to 55 percent off sitewide sales. MyProtein Impact Whey Isolate runs about $0.027 per gram of protein at sale pricing. Isopure Zero Carb runs about $0.058 per gram at standard pricing. The gap is real but Isopure does run major-holiday promotions.

Which is a true zero-carb isolate?

Only Isopure Zero Carb hits literally zero carbs per serving. MyProtein Impact Whey Isolate has 1 g of carbs per serving, which is close to zero but not exactly zero. For strict keto protocols where every carb matters, Isopure is the only choice. For most cutting protocols, both effectively deliver the same macro profile.

Which has better flavor, Isopure or MyProtein Impact Whey Isolate?

Isopure is widely considered the flavor benchmark for whey isolate. Dutch Chocolate, Creamy Vanilla, Cookies & Cream and Toasted Coconut are class-leading. MyProtein Impact Whey Isolate has improved meaningfully in recent years with Salted Caramel and Chocolate Smooth being top picks. Isopure still has the edge for overall taste experience.

Is MyProtein actually a quality brand at the lower price?

Yes. MyProtein is owned by The Hut Group and operates under strict UK manufacturing standards. The brand publishes Informed Sport batch testing results and uses standard high-quality dairy sourcing. The price advantage comes from European-scale operations, direct-to-consumer distribution and aggressive promotional pricing rather than ingredient corner-cutting.
