North American Kelp is proud to supply quality seaweed-based ingredients to manufacturers and formulators of nutritional supplements, animal feeds, pet products, products for horticulture and agriculture, and so much more. Our products can easily be shipped world-wide for use in international facilities.

We make all our products from fresh, locally harvested, sustainable seaweed from natural Ascophyllum nodosum seaweed beds in the pristine waters off the coast of Maine. We have been wild harvesting the same areas for over 50 years, and as the nation’s largest processor we take great care to protect this natural resource. For more information on our harvesting and sustainability, see our informational video here.

Our processing facility is located an hour or less from the landing docks, which means you’ll always receive the freshest products from us.  Our seaweed products have always been 100% made in the USA from domestically sourced ingredients.

Our prompt processing preserves beneficial vitamins and minerals in our kelp meal, for an optimal additive to fortify products for people, animals, soils, plants, and crops. No other single-ingredient supplement brings as much to the table!

Our seaweed extracts and fertilizers contain powerful bioactive compounds naturally found in these same seaweeds. Using a process fine-tuned over decades, we concentrate these compounds and fortify them with the nutrients needed to take crop production and quality to the next level. Our seaweed extracts add value to both conventional and organic plant foods, fertilizers, plant protection products, and plant growth enhancers. These products are available as concentrated liquid seaweed products and soluble seaweed powders.

Kelp Meal

Our kelp meals are renewable, minimally processed single-ingredient sources of vitamins and minerals for people, animals, and plants. We use a gentle drying process that doesn’t just preserve nutrients, but also preserves the color and mild savory flavor of the seaweed for a palatable nutritious supplement. Our kelp meals can be used as ingredients in human and animal food preparation, dietary supplement formulations, and to enrich plant foods, natural fertilizers, and compost blends. Available in USDA certified organic, OMRI listed for organic use, or all-natural options. No fillers, additives, dyes, chemicals, or preservatives, just 100% pure, dried Ascophyllum nodosum.

Seaweed Extracts and Fertilizers

We extract and concentrate nutrients and potent biological compounds to produce plant nutrient products, fertilizers, and plant biostimulants. Our products are especially effective at managing plant stress, which is becoming an increasingly important and cost-effective way to maximize productivity and crop yield in both traditional and organic agricultural practices. Our seaweed extracts and fertilizers add value to both conventional and organic agricultural and horticultural products, and are available as both liquid seaweed products and soluble seaweed powders.

Our extracts are also available for white labeling. We can provide bulk product for repackaging, contact us for more information.

Liquid Seaweed Products

Formulated with ease of use in mind, our liquid seaweed products are concentrated and ready-to-blend. As close to a 100% seaweed extract you can get. We don’t add any additional chemicals, fillers, or additives aside from acids and preservatives (0-4-4 only) to stabilize. We prefer working with what nature gave us; pure, unadulterated Ascophyllum nodosum. Both are suitable for foliar, soil, and fertigation applications.

Liquid seaweed products are available in 2.5 gallon jugs, 55 gallon drums, and 275 gallon bulk totes.
