A major review study encompassing roughly 8,000 participants found that consistent collagen supplementation improved skin elasticity and reduced osteoarthritis symptoms. Researchers also documented modest benefits for muscle and bone health among those taking collagen products.
Collagen is a structural protein abundant in skin, cartilage, and connective tissue. Supplement manufacturers have marketed collagen powders and capsules for years, but large pooled analyses provide stronger evidence than individual small trials.
The review aggregated data across multiple trials measuring dermatological and joint outcomes. Improved skin elasticity suggests measurable changes in skin biomechanics, while osteoarthritis symptom reduction addresses a common degenerative joint condition.
Scientists cautioned that supplement effects vary by dose, formulation, and baseline health status. The findings add to a growing body of nutrition research examining whether oral collagen can deliver clinically meaningful results beyond placebo effects.
