Kelp and other macroalgae move from snacks into protein-forward CPG: pasta, burgers, even sports nutrition.
What happened
Atlantic Sea Farms, Akua, and Notpla are scaling US East Coast seaweed supply chains as food brands seek climate-resilient protein.
Why it matters
Seaweed grows without freshwater, fertilizer, or arable land; it also absorbs carbon while it grows. The unit economics finally pencil out at scale.
Market impact
It's a hedge against soy and pea protein supply volatility, and a story brands can tell on-pack without invoking 'plant-based' fatigue.
Consumer insight
Younger consumers associate seaweed with health and sushi, not weird hippie food. This offers a clean perception slate to build on.
Strategic takeaway
Ingredient buyers should evaluate kelp-derived protein and fiber for 2027 launches. Supply will tighten as more brands move.
