The verdict, both ways

Read it through both lenses: which brand to trust for the category you’re buying, and who’s the stronger maker overall. They can give different answers — and that’s the honest result.

Lens 1 · for the category you’re buying

If you already know what you’re buying, the category decides it — pick the brand that leads the shelf you’re shopping.

So which brand?

Breadth vs focus — and the right answer depends on the shelf.

Go with Nutricost if…

…you care about its focus. It plays fewer fields (2) but is hard to beat where it does compete.

Optimum NutritionGo with Optimum Nutrition 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.

We don’t crown a winner. Globally they may both be top-tier; locally, the category can flip the answer. 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.
