We Know Seaweed

An early pioneer in the animal nutrition and plant biostimulants industries, North American Kelp has grown from humble beginnings as the Samoset Algae Co. in 1971 into the premier domestic processor of Ascophyllum nodosum in the USA and role model for the ethical, ecology-first management of a natural seaweed resource.

Our Products

Our products all start the same way: with locally & responsibly harvested brown seaweed, processed fresh year-round. Our process is tailored for the abundant, nutritious and bioactive-rich species Ascophyllum nodosum, allowing us to tap into decades of research and industry knowledge to bring you the best seaweed products.
