What Does Bentonite Clay Do For Your Body?
What is Bentonite Clay?
Bentonite clay is a naturally occurring clay composed primarily of montmorillonite, which is a type of smectite (ref). It forms from the weathering of volcanic ash, most often in the presence of water. Bentonite has a high cation exchange capacity and can absorb water easily, making it expand like a sponge. People have used bentonite medicinally for centuries, and it has a long history of traditional use in natural remedies.
There are several types of bentonite clay. Sodium bentonite is one common type and has excellent swelling ability. Calcium bentonite contains more calcium and is commonly used for industrial purposes. According to WebMD, key properties of bentonite clay include: ability to absorb toxins, help
protect the body from harmful organisms, and potentially aid in nutrient absorption (ref).
How Does Bentonite Clay Work?
Bentonite clay has powerful absorption and adsorption properties that allow it to attract and remove toxins and impurities (1). It has a strong negative electrical charge, while toxins and impurities have a positive charge (2). This allows the clay to bind to them electrostatically when they come in contact. According to research, bentonite clay has a high ion-exchange capacity and surface area, which gives it excellent toxin binding abilities (1).
Specifically, bentonite clay works through a process called adsorption, where molecules of toxins attach to the surface of the clay particles (2). The toxins get trapped within the clay’s layered structure and are then eliminated from the body. The clay’s absorption capacity also allows it to absorb oils and sebum from the skin, helping remove dirt and bacteria (2). Overall, bentonite clay’s unique chemical structure gives it the remarkable ability to absorb, adsorb, and bind toxins both internally and topically.

Benefits of Bentonite Clay
Bentonite clay provides several health benefits when used internally or topically. Some of the main benefits include:
Detoxification
Bentonite clay is known for its ability to remove toxins and impurities from the body. It has a strong negative ionic charge, which bonds to the positive ions of toxins and helps absorb and remove them before they can be absorbed into the bloodstream (1). This detoxifying effect may help remove heavy metals, chemicals, and impurities from the gut and skin.
Skin Clarifying
Applying bentonite clay to the skin provides cleansing, soothing, and clarifying effects. The clay can help absorb oils, remove dead skin cells, and lift out impurities from pores to reduce acne and improve skin clarity (1). Its antibacterial properties may also help soothe skin conditions like eczema, psoriasis, and rashes (2).
Digestive Aid
When ingested in appropriate doses, bentonite clay can help absorb toxins and impurities from the digestive tract. Its absorbent nature may help reduce symptoms of diarrhea and relieve occasional constipation by promoting regularity (2). Some evidence suggests bentonite clay may also help eliminate certain toxic pathogens like aflatoxin from the gut when bound to it (1).

Using Bentonite Clay Internally
When taken orally, bentonite clay can act as a detoxifying agent and promote gut health. However, it’s important to start with small doses and gradually increase intake to avoid side effects.
According to research, most recommendations suggest starting with 1/2 teaspoon of bentonite clay mixed in water or juice once per day. This low dose helps assess tolerance. The dose can then be slowly worked up to 1-2 teaspoons taken 1-3 times per day. It’s best to take bentonite clay on an empty stomach, at least 1 hour before or after eating (source).
To maximize detoxification effects, some natural health experts recommend doing a bentonite clay detox for 2 weeks at a time, taking doses spread throughout the day. Then taking a break for 1-2 weeks before doing another round. Always drink plenty of water when consuming bentonite clay internally to help flush out toxins (source).
It’s important to note that bentonite clay can interact with certain medications. Check with your doctor before consuming, especially if taking prescription drugs regularly.
Using Bentonite Clay Topically
One of the most popular uses of bentonite clay is topically on the skin in the form of masks and packs. When applied topically, bentonite clay can provide many benefits for skin health, appearance, and wound healing.
Bentonite clay masks and skin packs can help absorb excess oil and sebum from the skin’s surface (source). This helps reduce shine, balances oil production, and minimizes the appearance of pores. The clay is able to draw out impurities without stripping the skin of its natural oils. Using a bentonite clay mask 1-2 times per week can be an effective part of an acne-fighting skin care routine.
In addition to drawing out impurities, bentonite clay also delivers minerals to the skin including calcium, copper, and zinc (source). This makes it helpful for soothing acne breakouts, blemishes, and irritation. The anti-inflammatory properties of bentonite clay reduce redness and inflammation associated with breakouts. It may also help speed healing and reduce the appearance of acne scars over time.
When applied topically as a paste, bentonite clay can help speed wound healing, reduce inflammation, and fight off infection (source). Its absorptive powers draw out dirt and debris from injuries, while delivering antimicrobial, skin-soothing minerals. Applying a bentonite clay poultice can protect scrapes and cuts from environmental irritants during the healing process.
Bentonite Clay Side Effects
While bentonite clay is generally safe for most people when used in moderation, there are some potential side effects to be aware of:
Constipation Risks – Bentonite clay has strong absorbent properties and can absorb water from the digestive tract, potentially leading to constipation in some people. Those with pre-existing constipation or dehydration should use caution when ingesting bentonite clay internally (1).
Drug Interactions – Due to its absorptive nature, bentonite clay may bind to certain medications and prevent proper absorption when taken simultaneously. It is recommended to space out medication and bentonite clay ingestion by at least 2 hours (2).
Avoid Use When Pregnant or Breastfeeding – There is not enough research to establish the safety of bentonite clay for pregnant or breastfeeding women. It is best avoided or used minimally during pregnancy and breastfeeding (3).
Heavy Metal Risk – Some bentonite clay products may contain traces of heavy metals like lead or arsenic, which can be harmful with repeated or excessive use. Choosing a reputable brand that lab tests for heavy metals can minimize this risk (1).
Skin Irritation – Topical use of bentonite clay masks may cause redness, itching, or irritation in those with sensitive skin. Doing a patch test before wider application can help identify potential irritation (2).
Overall, bentonite clay side effects are uncommon when used occasionally and in moderation. But some people should use extra caution or avoid use altogether. Speak with a doctor before using bentonite clay if you have any concerns.

How to Choose a Bentonite Clay
When choosing a bentonite clay, it’s important to consider the type and quality of the clay. There are two main types of bentonite clay:
- Sodium bentonite: This type of clay swells more in water and is more effective for detoxing. It’s often referred to as “swell clay.”
- Calcium bentonite: This doesn’t swell as much in water. It’s sometimes called “non-swell clay.”
In most cases, sodium bentonite is preferred for health uses because of its stronger detox properties. However, some people prefer calcium bentonite if they find sodium clay too strong 1.
When looking at brands, choose a reputable company that sources pure, high-quality bentonite clay. Look for a clay that’s unlabeled as “food-grade” or “safe for ingestion” 1. The clay should be a very fine, smooth powder with no grittiness or impurities. It should also have a grayish or cream color.
Ideally, the bentonite clay should be sourced from an area with clean water and minimal contamination. Many reputable brands source their clay from regions like Wyoming or regions of Europe 2.
Always check reviews and the company’s reputation. Higher quality, purer bentonite clays may cost more, but are worth it for safety and effectiveness.
