The Celtic Sea Salt Brand is recommended by doctors and culinary chefs worldwide. It is lower in sodium, certified kosher and more nutritious than table salt. Light Grey Celtic is a whole crystal (coarse), moist salt that is mineral-rich, completely unrefined and hand harvested. Dried by the sun and the wind; it retains the ocean’s moisture, locking in a vast array of vital trace elements. Light Grey Celtic gets its light grey hue from the pure clay lining of the salt beds where it is harvested.
