The Surprising Ingredient Making Waves In Food, Beauty & Sustainability

Once considered a part of the ocean backdrop, kelp is emerging as a very hot commodity. One of the most promising regenerative resources available today, its applications span food, supplements, beauty, soil health, and beyond. 

In this comprehensive guide, we’re exploring what makes Alaskan kelp unique, how it supports the body internally and externally, why the super-ingredient should be on your radar screen and the innovative products bringing it into everyday life.

What is Alaska kelp & what makes it a standout?

In case you need to start at the baseline, kelp is a large, nutrient-rich marine algae that grows in underwater forests along coastlines. It serves several functions. It creates a vital ecosystem for ocean life, providing resources for marine organisms and coastal communities. For centuries, humans have harvested kelp for a variety of uses, from food to traditional medicine. 

More recently—with the emergence of eco-friendly marine farming—it’s also being grown for use in supplements, food, beauty products, and so much more. 

Alaska, in particular, is becoming an epicenter of kelp cultivation. Since starting commercial kelp farming in 2017, Alaska’s kelp industry has expanded significantly. Alaska kelp is sourced through a combination of wild harvesting and thoughtfully managed kelp farms, supported by clean waters, rigorous standards, and a deep heritage of coastal stewardship. Sustainability and responsible resource management is literally written into Alaska’s state constitution.

Alaska’s unique marine ecosystem

Alaska’s cold coastal waters are nutrient-rich, providing a healthy ocean ecosystem with minerals that support kelp growth. 

The result is kelp that boasts benefits that reach far beyond traditional seaweed.

All of these factors make Alaska-grown kelp uniquely positioned as a nutrient-dense, future-focused ingredient—one that supports people, products, and the planet in measurable ways.

While Alaska kelp species share similar nutritional values, not all kelp is the same. Alaska’s waters produce several valuable species, each with its own characteristics and uses. A few key species include: 

Environmental benefits of Alaska kelp farming

No deep dive on Alaskan-grown kelp is complete without a spotlight on its sustainability benefits. As a regenerative crop, it offers a rare opportunity to produce more while taking less from the environment—and kelp cultivation works in harmony with its surrounding ecosystem.

It’s an ingredient that doesn’t just minimize impact, but it actively contributes to healthier oceans and more resilient coastal communities.

Alaska kelp uses 

Alaska kelp’s potential is vast. Here is a spotlight on a few of the many uses: 

Agriculture

Interestingly, Alaska kelp can actually support agriculture on land too. For example, it can be used as a fertilizer, biostimulant, and even a component in animal feed. These applications leverage kelp’s natural compounds to enhance soil structure, improve nutrient uptake, and support plant resilience.

Pacific Kelp Company produces a liquid kelp biostimulant called KelpEdge that supports root development, soil health, and crop productivity, offering a more sustainable option for growers.

Food & dietary supplements

One of the most traditional and widely recognized uses of kelp is simply eating it—and today, its use is expanding beyond its history in coastal cuisines. Alaska kelp shows up as a food ingredient, flavor enhancer, thickening agent, and dietary supplement, thanks to its natural umami flavor and dense nutrient profile.

Delicious, briny, and thoroughly nutrient-dense, the culinary uses of Alaska kelp are endless. For example, Barnacle Foods turns Alaska kelp into pantry staples like hot sauce, chili crisp, seasonings, and more—showcasing how simple it is to incorporate kelp into everyday cooking.

Skin, hair & beauty

Beauty is big business, and as consumers become more ingredient-savvy, brands are searching for solutions that are effective, sustainable, and buzz-worthy. Used in topical formulas, Alaska kelp can support both skin and hair health through its antioxidants, plant compounds, and naturally occurring minerals.

Brands like Eirwen leverage sugar kelp to support hydration, radiance, and barrier function—using its marine polysaccharides to help attract and retain moisture while antioxidants and minerals contribute to resilience and visible glow.

Alaska kelp: Why it’s more than a trend

As part of a larger shift toward regenerative resources that nourish people, Alaska kelp harvesting and farming can support circular economies and aid in restoring ecosystems. It stands at the convergence of tradition and innovation, making it one of the most versatile and impactful ingredients to date.
