Kelzyme® was founded in the 1980s and trademarked in the 1990s under different names to mine, license, test and market the deposit of fossilized sea kelp discovered in Northern Nevada. Since then, Kelzyme has grown as a company and now makes its unique product available to commercial agricultural growers and home gardeners looking for a simple and organic alternative. The Kelzyme® offices are located in Brooklyn, New York & Mill City, Nevada with our production facilities in Northern Nevada.
