Where Diatomaceous Earth Forms

Food Grade Diatomaceous Earth forms by diatoms absorbing the mineral content within a water body to form a shell around their cell membrane.  These diatoms, in this particular case, absorbed a high amount of silica and low amount of metals within this particular body of water in the Reno, NV region of the United States.  Over thousands of years, these diatoms build up on top of each other forming a huge fossilized deposit.  As a result, these diatoms formed when dinosaurs roamed the earth!  Now, the diatom itself is a particular one called the Aulacoseira diatoms created in the Miocene Epoch


How Diatomaceous Earth Forms

The shell formed around the diatom’s cell is considered to be primarily amorphous silica.  Its shape and hardness have everything to do with how it works.  It hardness keeps it from dissolving like other hard minerals.  The diatom’s tubular shape and holes along the diatom’s wall allow it to absorb moisture, hence its use as an anti-caking agent!  Firstly, the important tubular shape of the diatom gives more surface area compared to other shaped diatoms.  Which means it has greater absorptive capacity with the holes that open to the center.  This allows the diatom to absorb unwanted fungus and bacteria within the gut!   Food Grade Diatomaceous Earth does not swell in the stomach and has no physical or chemical capability to absorb nutrients, medicines, or herbs.

Lastly, Food Grade Diatomaceous Earth is almost all silica at 89% and is pure white to off-white in color, showing its purity.  There are other mines of Food Grade Diatomaceous Earth here in the US and world.  You will find other mines, surprisingly,  have a product almost grey or red in color. Having higher amounts of iron and other metals is hazardous to ingest.  Food Grade Diatomaceous Earth is OMRI organic.
