Collagen supplements fail to deliver on bold health promises, study reveals
Collagen supplements have long been marketed as a solution for smoother skin and healthier joints. Yet recent research suggests these claims lack strong scientific backing. A new meta-analysis has found little evidence to support the advertised benefits, raising questions about their real value.
The latest review of studies on collagen supplements found no clear advantages for human health when excluding industry-funded research. Many earlier trials suffered from weak methods, such as small participant groups, brief durations of just 8 to 12 weeks, and a reliance on self-reported feedback rather than precise measurements. Even when modest improvements appeared, they were often limited to skin hydration rather than deeper structural changes.
The evidence suggests collagen supplements deliver little more than placebo-level effects. With most studies showing only minor hydration improvements—and none proving lasting structural benefits—consumers may find better results from a nutrient-rich diet. For now, the scientific consensus remains clear: whole foods remain the most reliable source of protein for skin and joint health.
