The wellness industry has built a $1.5 billion collagen market on claims that oral supplements reach skin and joints intact—a claim that contradicts basic digestive biology, yet persists because regulatory gaps let brands make efficacy assertions without clinical proof. Major retailers and influencers continue promoting collagen as a beauty and performance tool despite the absence of peer-reviewed evidence. The market demonstrates how consumer trust in wellness spaces has decoupled from scientific rigor. Collagen sits at the center of how the supplement industry operates: it captures consumer willingness to pay premiums for biologized solutions to aging and injury, regardless of whether the mechanism works.
