Marine Collagen Gains Recognition as Superior Supplement for Skin Health
New research indicates marine collagen, derived from fish skin, is proving to be a more bioavailable and effective supplement for improving skin health compared to other collagen types.
Collagen, a protein vital for skin’s strength and elasticity, naturally depletes with age, beginning in our early 20s. Experts describe collagen as the “scaffolding” of the skin, providing support and firmness. Types one and three are the most abundant in skin, with type one accounting for 80% and type three for 15%. Hydrolyzed marine collagen is rich in Type 1 collagen, the most prevalent in human skin, and is showing promising results in clinical trials. “Marine collagen is structurally closest to the collagen found in human skin, which makes it incredibly effective – particularly for improving skin health,” says Anna Lahey, founder of Vida Glow.
The key difference lies in its molecular size; marine collagen’s smaller peptides allow for easier absorption by the body, reaching the deeper layers of skin where new collagen is produced. Other forms, like bovine or porcine collagen, have larger molecular weights that limit absorption to the skin’s outer layer. This increased bioavailability translates to improvements in skin elasticity, reduced wrinkle depth, and enhanced hydration with consistent daily use. Maintaining skin health is increasingly important as the global anti-aging market continues to expand, projected to reach over $83 billion by 2030.
Beyond skin benefits, marine collagen supports overall structural integrity, contributing to stronger hair and nails, and offering broader health benefits as the body utilizes collagen throughout. “The body uses collagen throughout — so replenishing it doesn’t just show up on your face. It’s an investment in total wellbeing,” Lahey suggests. Further research into collagen supplementation can be found at the National Institutes of Health.
Researchers continue to investigate the long-term effects of marine collagen supplementation, with ongoing clinical trials expected to provide further insights into its potential benefits in the coming months.
