What is Bentonite Clay?

Bentonite clay is harvested from ancient volcanic ash deposits that typically have landed in a marine environment. Over time, the ash weathers and ages to become bentonite clay. For thousands of years, humans have used bentonite clay to promote health internally and externally, as well as supporting healthy crops and livestock.

What is bentonite clay and where does it come from

Just like living organisms, rocks and minerals are organized into groups based upon physical and chemical characteristics. Bentonite clay belongs to a mineral family called smectites.

  • Smectites: a group of phyllosilicate minerals (specific configuration of silicon or sometimes aluminum, and oxygen molecules).
  • Bentonite clay: a smectite clay named for the region where the mineral was originally found (near Benton Wyoming).
  • Montmorillonite clay: a smectite clay named for the where the mineral was originally found (near Montmorillon, France). Same clay as bentonite, just named for its region of discovery.

The names bentonite, montmorillonite, and smectite are sometimes used interchangeably by manufacturers.

What Makes Smectite Clays Special?

Smectite clays are made of plate-like grains with a rather large surface area. This unique physical structure gives them some incredibly useful chemical characteristics.


Smectite clays are very adsorptive. Adsorption is a solid substance’s ability to hold gas or liquid molecules as a thin film on its surface. With a large surface area and a naturally negative charge, smectite particles can gather and store a large quantity of positively charged cations.


Smectites like bentonite and montmorillonite are also very powerful absorbers. Absorption is a solid substance’s ability to completely soak up and retain gas or liquid molecules.

Toxin Binding

According to the National Institute of Health (NIH), these clays can also bind to harmful toxins more efficiently than even charcoal. By binding to both man-made and naturally occurring toxins, smectites can prevent living tissues from absorbing harmful substances.

Clay for Animal and Soil Health

Clay particles store minerals in a way that makes them biologically available to living organisms. Through adsorption and absorption, they can attract essential minerals and electronically exchange them with living tissues. They can also bind to substances that would otherwise irritate and harm these same tissues. The NIH study mentioned above has found that bentonite clay can:

  • Prevent and treat skin lesions, ulcers, and rashes
  • Treat digestive upset
  • Support gut microbe colonies
  • Increase gut nutrient absorption
  • Boost immune response
  • Improve renal health and kidney function
  • Regulate thyroid health
  • Act as a natural antibiotic for some harmful bacteria strains
  • Reduce the bioavailability of toxins

Clay particles also produce a wide range of plant health benefits:

  • Stabilizes soil (especially important for loose, sandy soils)
  • Improves soil moisture
  • Stores positively charged nutrients to exchange with plant roots

Redmond Clay Conditioner

The winning combination of volcanic ash deposit and marine environment created the Redmond clay and mineral deposit in central Utah. Redmond Conditioner is harvested from this incredibly unique resource, and has spent millions of years attracting over 60 trace minerals from the surrounding deposit. For over 50 years, farmers have enjoyed the many health and productivity benefits of our clay and mineral mixes.
