So which brand?

Breadth vs focus.

MyProteinGo with MyProtein if…

…you want range and the safe default. It is in the mix and competes across 3 fields, so there's a fit for most needs.

Optimum NutritionGo with Optimum Nutrition if…

…you care about its focus. It plays fewer fields (3) but is hard to beat where it does compete.

We don’t crown a winner. Pick the brand that’s strong where you’re actually shopping — when a brand doesn’t compete in a category, we leave it blank rather than invent a rank.
