Collagen peptides from marine by-products: From waste to functional ingredients.
Collagen peptides are getting a serious upgrade, and it’s all thanks to marine by-products that used to be tossed out as waste. Researchers are now turning fish skins, bones, and even invertebrate shells into functional ingredients packed with bioactive potential. This isn’t just about cleaning up the seafood industry. It’s about building a sustainable supply chain for research peptides that can be fine-tuned for specific uses.

“Collagen peptides from marine by-products: From waste to functional ingredients. Ashaolu TJ(1). Author information: (1)Institute for Global Health Innovations, Duy Tan University, Da Nang 550000, Viet Nam.; Faculty of Medicine, Duy Tan University, Da Nang 550000, Viet Nam.

The valorization of marine by-products represents a critical intersection of environmental sustainability and the burgeoning wellness industry. This review provides a comprehensive assessment of recent literature in the past five years concerning the production, bioactivity, and application of collagen peptides (CPs) derived from marine processing side streams. It critically examines the entire value chain, from the diverse vertebrate and invertebrate sources to the extraction and hydrolysis methodologies that dictate the final product's physicochemical and biological properties. A detailed analysis of the clinical evidence supporting the efficacy of marine CPs in dermatological, musculoskeletal, and bone health is presented, highlighting a clear hierarchy of validation. We also explore a spectrum of other promising bioactivities, including antioxidant and antihypertensive effects, which are primarily supported by preclinical data. Major challenges, such as inconsistent clinical outcomes, are deconstructed through a root cause analysis that links variability in raw materials and processing to a lack of product standardization. Finally, critical knowledge gaps were identified while proposing a future research trajectory focused on elucidating structure-function relationships, optimizing processing for targeted peptide profiles, and conducting methodologically robust clinical trials. The central idea is that this area of research is moving from the discovery of a valuable bioresource to precision to unlock its full potential as a source of evidence-based nutraceuticals. This review also underscores the industrial potential of marine collagen peptides in promoting sustainable bioprocessing and creating high-value nutraceuticals, aligning with circular economy goals.

Here’s the deal: The last five years have seen a surge in studies exploring how to extract, hydrolyze, and optimize marine collagen peptides. The goal? Pinpoint the exact processing methods and sources that deliver peptides with the best biological properties. The review covers everything from the nuts and bolts of extraction to the science behind what makes some marine collagen peptides more effective than others.
Key takeaway: Marine collagen peptides aren’t just for skin creams and bone health anymore. Preclinical data is stacking up on antioxidant and antihypertensive effects, hinting at even broader research opportunities. Clinical results are promising, especially for skin and joint studies, though there’s still work to be done standardizing raw materials and processing methods.
Researchers are targeting:
Dermatological, musculoskeletal, and bone health research
Antioxidant and blood pressure support (early-stage data)
Sustainable production methods that align with circular economy goals
Challenges remain, mostly around consistent sourcing and standardization. But the field is shifting from basic discovery to precision research. The next step is dialing in structure-function relationships and running stronger clinical trials.
