Animal Essentials Ocean Kelp is dried at a uniform low temperature by hot geothermal water fed through heat exchangers. This procedure ensures all the minerals and organic substances are preserved, prevents surface oxidation and browning of the meal as often seen in oil, coal-dried or sun-dried product. The use of the geothermal water also means the production process is very environmentally friendly. This Premium quality, USDA Certified Kelp is harvested from the icy waters of Northwestern Iceland where it naturally grows in a clean environment rich in alluvial minerals. It is harvested with the strictest international standards for sustainability, separation of raw material, traceability of products and contamination control at all stages of the production process.
