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.
- Higher concentrations of active compounds and stronger functional properties
- Superior texture and overall stability
- Unpolluted waters for cleaner output
- Greater biodiversity with species not found elsewhere
- Traceability and strong regulatory oversight supporting responsible cultivation
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.
Alaska kelp nutrient profile: vitamins, minerals & health benefits
That highly specific ecosystem fosters a marine crop chock-full of compounds that are linked to metabolic health, cellular benefits, bone strength, and so much more.
Notable nutritional info
A nutrient-rich growing environment means Alaskan Kelp contains loads of good-for-you antioxidants, bioactive, and minerals. Plus, kelp is naturally high in dietary fiber.

9 full-body benefits
Put that all together and you’ll get a wide range of health perks, both internally and externally:
- Bone strength: Calcium1 and vitamin K2 work together to support bone density and healthy formation.
- Muscle health: Magnesium3 and potassium support skeletal muscle tissue and recovery.
- Metabolism management: Magnesium4 and iodine contribute to energy production and metabolic regulation.
- Thyroid support: Natural iodine5 helps maintain healthy thyroid hormone production.
- Inflammation modulation: Antioxidants and bioactive compounds can help support balanced inflammatory pathways.
- Cardiovascular health: Potassium6 helps maintain healthy blood pressure, while antioxidants support vascular function.
- Immune resilience: Folate7, vitamin A, and polyphenols play roles in cellular defense and immune response.
- Gut health & weight management: Fiber supports digestion, regularity, and fullness between meals.
- Skin support: Minerals8 and antioxidants contribute to hydration, elasticity, and environmental defense.
Alaska kelp species & their differences:
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:
- Sugar kelp: Golden-brown ribbons with a mild umami flavor; ideal for cooking and rich in micronutrients. Sugar kelp also has hydrating elements and antioxidant properties, making it a key ingredient in beauty products as well.
- Ribbon kelp: Long, structured blades with hearty texture for recipes like noodles, soups, and plant-based alternatives.
- Bull kelp: Known for its briny, pickled crunch and fiber content; historically relied on in coastal food traditions.
- Giant kelp: The fastest growing kelp species by biomass; full of nutritious compounds that are extracted and used as soil enhancers and fertilizers.
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.
- As it grows, kelp naturally absorbs carbon and helps reduce excess CO2 in the ocean, helping to buffer the effects of acidification.
- Kelp relies entirely on the nutrients already present in the ocean—there’s no irrigation, no pesticides, and no depletion of terrestrial resources.
- Kelp forests provide habitat for young fish and marine life, supporting biodiversity without disturbing existing ecosystems.
- Kelp farming bolsters working waterfronts and creates opportunities for coastal communities rooted in fishing and maritime heritage.
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.
