Marine collagen is on track to become a $1.01 billion global ingredient category by 2031, up from $740 million in 2026, according to new forecast data from MarketsandMarkets™. The 6.6% compound annual growth rate signals sustained shelf momentum for CPG brands operating in the functional food, supplement, and beauty-from-within segments — and raises the stakes for category managers evaluating where collagen fits in their planograms.
What's Driving the Shelf
Clean-label positioning is the primary commercial tailwind. Shoppers increasingly equate marine-derived collagen — sourced primarily from fish skin and scales — with transparency and sustainability, attributes that outperform bovine or porcine collagen in consumer perception studies. Superior bioavailability, a function of smaller peptide particle size, gives marine collagen a clinical story that brand marketers can credibly merchandise in the functional foods aisle alongside protein powders, ready-to-mix drinks, and fortified snacks.
The natural and specialty channel has been the early velocity leader for marine collagen SKUs, where scan data consistently shows above-average turn rates relative to conventional collagen formats. But the ingredient is moving fast into the mass channel and club channel as established CPG players — ranging from supplement-focused national brands to private-label own-brand programs — build out collagen platforms to capture aging-consumer spend. End-cap placement and in-store display programs in the supplement and functional beverage sections are becoming competitive battlegrounds for TDP gains.
Category Implications for Retailers
For grocery retailers, marine collagen's growth trajectory creates both a slotting opportunity and a private-label imperative. Store-brand programs that lag on collagen SKUs risk ceding high-margin supplement real estate to national brands backed by trade promotion spending and MCB programs. Retailers with strong own-brand supplement lines — a category where private label has steadily taken share from national brands — should be evaluating marine collagen as a near-term formulation priority.
The functional food angle is equally significant. Marine collagen is increasingly appearing as a fortification ingredient in categories beyond traditional capsules and powders: think collagen-infused coffee creamers, protein bars, and even shelf-stable soups. CPG developers tracking functional food and beverage trends will find marine collagen converging with the broader better-for-you movement that has reshuffled planograms across center store over the past five years.
With MarketsandMarkets™ projecting steady six-plus percent annual growth through 2031, marine collagen is no longer a niche ingredient story. It's a category-management conversation — one that touches product development, sourcing strategy, and retail shelf architecture simultaneously.
