July 2026 in “Marine Drugs” In this mouse study, researchers found that orally administered low-molecular-weight fish collagen peptides significantly improved hair regrowth by both enhancing growth-promoting pathways and reducing inhibitory mechanisms.
December 2025 in “PubMed” This study suggests that low molecular weight fish collagen peptide may promote hair follicle growth and regeneration, improving overall hair quality in mouse models.
September 2023 in “Journal of microbiology and biotechnology” This study found that low molecular weight collagen peptide from fish may promote hair growth in both human cells and mice by activating the Wnt/β-catenin signaling pathway.
January 2026 in “International Journal of Peptide Research and Therapeutics” In this study, adults with mild-to-moderate hair damage taking GPVGPS Collagen® daily for 24 weeks showed significant improvements in hair luster, strength, thickness, and density compared to placebo, with no safety concerns reported.
This review reports that oral collagen peptide supplements may improve skin elasticity, hydration, and wrinkle appearance while also supporting hair and nail health and wound healing, but emphasizes the need for longer, high-quality studies due to current research limitations and variability in findings.
