Diatomaceous Earth, Fossil Shell Flour

Diatomaceous Earth, also known as DE and Fossil Shell Flour, is the fossilized remains of hard shelled, one celled plants called Diatoms. These plants lived in the oceans and other bodies of water that once covered the western part of the United States. The Diatoms served as a food source for aquatic life. When they died, their shells drifted to the bottom of the body of water. Millions of years later, huge deposits of Diatomaceous Earth were discovered after the water receded.

There are hundreds of sources of Diatomaceous Earth and most deposits are from salt water sources. The ones found in fresh water sources are of extremely high purity. It is so pure it is called food grade Diatomaceous Earth. Only 4 sources of over 600 deposits can be called food grade.

Freshwater diatomite is mined from dry lakebeds and is mostly hydrated amorphous silica. Perma-Guard food grade Diatomaceous Earth contains less than .5% crystalline. The saltwater form contains a highly crystalline form of silica that can be dangerous if inhaled. When you purchase Perma-Guard food grade Diatomaceous Earth, you are assured you are getting the finest quality Diatomaceous Earth available.

Perma-Guard uses only Diatomaceous Earth from fresh water deposits. Perma-Guard held the original patents in 1962 for use as a food additive. Thousands of animal owners and breeders have discovered incredible benefits by adding food grade Diatomaceous Earth or Fossil Shell Flour to their animal's food.
