Coming from fossilized hard-shelled algae found in bodies of water, these diatomaceous earth powders are commonly used as a natural pesticide and to improve human and pet health. Like all supplements, the purported health benefits have not been evaluated by the FDA, but it is often recommended by naturopathic doctors.

Editor's Notes

August 28, 2019:

The usage of diatomaceous earth as a health supplement is not backed up by clinical studies, it remains a favorite of natural health practitioners and patients alike. When evaluating the best we looked for brands with a solid reputation for quality, especially in the food grade choices and certification by an official body, like being listed by the Organic Materials Review Institute (OMRI).

Diatomaceous Earth Food Grade takes the top spot for the company's meticulous attention to the food safety aspect for those whose primary usage will be as a health supplement. We also like that it comes in an eco-friendly recycled bag.

We decided to include two non-edible options, the St.Gabriel Laboratories Insect Dust and the Safe Brand 51703 for those looking for simple pest control, because these choices are priced less per pound. They make a great alternative to chemical-laden sprays for Fleas and Ticks or Bed Bugs.

5. St. Gabriel Laboratories Insect Dust
