This peer-reviewed review discusses clinical studies on hydrolyzed marine collagen showing a 9% increase in dermal collagen density and improvements in skin wrinkling, echogenicity, and collagen morphology after 90 days of supplementation. It highlights promising anti-aging effects but notes limited long-term data and the need for robust safety studies. The evidence supports potential regenerative properties, though recommendations remain cautious due to preliminary findings.

This Frontiers in Nutrition article reviews over 60 clinical studies on collagen supplementation, including hydrolyzed forms, indicating improvements in skin elasticity, joint function, and exercise recovery, especially with co-supplements like vitamin C. It covers marine-derived collagen in the context of anti-aging and regenerative applications. Advances in biosensors and delivery systems are highlighted for precision monitoring and therapy.

The report projects the global marine collagen market to grow from USD 1.0 billion in 2025 to USD 1.92 billion by 2034 at a 7.5% CAGR, driven by fish byproduct utilization, beauty/nutrition demand, and Type I collagen dominance (62% share) for skin health in the US and globally. US market trends emphasize anti-aging supplements, sustainability, and supply chain innovations. North America sees strong growth in ingestible beauty products.
