Frequently asked questions

Is Myprotein better than Optimum Nutrition?

It depends on the SKU. Compare live Index /100 (formulation checks, sugar, value) and $/25g on this page — brand reputation alone is not a score.

How does WheyIndex score these brands?

Index /100 weights protein delivery (45%), same-market/category value (35%), and testing evidence (20%). Affiliate relationships never change scores. See /how-the-index-works.
