Lumino Diatomaceous Earth Pure Fresh Water (DE) is not earth or dirt. It is the fossilized remains of microscopic shells created by one-celled aquatic plants (diatoms). Over the eons, as these diatoms fossilized, they retained their tubular shape and holes. Their shape and hardness produce extremely pure and consistent DE. There are different grades of DE in the marketplace. Of the 600 deposits in the U.S., only four are considered Food-Grade by the FDA. Lumino DE is almost pure white and consists of 89-94% silicon dioxide plus 28 trace minerals.
There are also two basic original sources: fresh water and salt water. These fresh water deposit began eons ago as pure snow. The snow’s run off provided the water source the diatoms lived in. Diatoms in fresh water form a harder shell than those in salt water. The silica in Lumino DE is amorphous. This is silica in its naturally occurring state. It is a trace mineral every mammal on the planet needs for survival. The silica in DE becomes crystalline when it is exposed to extreme heat through volcanic activity or commercial manufacturing.
