About
Layne Norton is a nutritional scientist and competitive powerlifter known for rigorous evidence standards and willingness to publicly challenge supplement industry claims. His content frequently debunks overhyped products and calls out weak study designs.
Our approach to his mentions
Norton is one of the most valuable voices in our model because his skepticism is informed, not reflexive. When he's cautious about a product, it usually means the evidence has real gaps. When he supports something (creatine, protein, caffeine), the case is strong.
When the evidence changes, we’ll tell you.
