Bentonite clay contains montmorillonite, an aluminum phyllosilicate mineral with high cation exchange capacity that binds toxins and heavy metals. Its negatively charged surface attracts positively charged toxins in the digestive tract, facilitating their elimination through fecal excretion.
Reported Benefits (Provisional)
Origin & History
Bentonite Clay, also known as Montmorillonite, is a natural clay formed from volcanic ash. It is mined from deposits and processed for various health and beauty applications.
Research Narrative (Provisional)
Studies on Bentonite Clay focus on its detoxifying properties and ability to bind toxins. Some research supports its use in treating skin conditions and digestive health.
Preparation & Dosage

Nutritional Profile
Bentonite clay is not a nutritional ingredient in the conventional sense and provides negligible caloric, protein, fat, or carbohydrate value when consumed. It is a phyllosilicate clay mineral composed primarily of aluminum phyllosilicate (Al2O3·4SiO2·H2O), with montmorillonite as the dominant mineral phase (~70-90% of composition). Key mineral constituents include silicon dioxide (SiO2, ~54-60% by weight), aluminum oxide (Al2O3, ~16-20%), magnesium oxide (MgO, ~2-3%), calcium oxide (CaO, ~1-3%), iron oxide (Fe2O3, ~3-5%), sodium oxide (Na2O, ~0.5-2%), and potassium oxide (K2O, ~0.5-1%). Trace minerals present include manganese, zinc, copper, and selenium in sub-milligram quantities per gram. The clay carries a strong net negative electrical charge when hydrated, giving it a cation exchange capacity (CEC) of approximately 60-120 milliequivalents per 100g, which is the primary bioactive mechanism enabling binding of positively charged heavy metals (lead, mercury, cadmium, arsenic) and mycotoxins such as aflatoxin B1. Bioavailability of its mineral content is extremely low due to the tightly bound silicate crystal lattice structure; minerals are largely non-bioavailable for human absorption. Fiber content is negligible. The clay swells to approximately 12-15 times its dry volume upon hydration, forming a gel-like matrix critical to its adsorptive function. No significant vitamins are present.
Reported Mechanism (Provisional)
Montmorillonite's layered silicate structure creates a high surface area with negative electrical charge, enabling cation exchange with positively charged toxins like lead, mercury, and cadmium. The clay's swelling properties allow it to absorb up to 10 times its weight in water and dissolved substances. This binding occurs through electrostatic attraction and ion exchange mechanisms in the gastrointestinal tract.
Clinical Narrative (Provisional)
Human studies on bentonite clay are limited, with most evidence from small-scale trials and animal research. A study of 35 participants with IBS showed modest improvements in bloating and discomfort after 6 weeks of use. Animal studies demonstrate heavy metal binding capacity, but human detoxification claims lack robust clinical validation. More large-scale, placebo-controlled trials are needed to establish therapeutic efficacy.
