SelfDecode excerpt
What if there was a “magic powder” that purifies the water, enriches the soil, and removes nuclear waste? What if that same powder could detox your body, boost your gut health, prevent free-radical damage, fight infections, and more? Well, zeolite might do it all, but clinical evidence remains limited.
What is Zeolite?
Zeolite is a complex mineral which forms in the contact of volcanic lava and water. This process can take thousands or even millions of years; scientists estimate that the first zeolite minerals formed over 300 million years ago.
“Zeolite” is a common name for over 240 unique structures (or frameworks), of which 40+ occur in nature. The most common types of zeolite include [1]:
Clinoptilolite
Mordenite
Analcime
Chabazite
Natrolite
Stilbite
Ancient Romans used zeolite B.C. to build bridges. Then it fell into oblivion and found its way back in 1756 when Swedish mineralogist Axel Cronstedt first described and named it.
He merged two Greek words: zéō, meaning “boiling” and líthos, meaning “stone.” Zeolite released plenty of steam when heated and thus reminded Cronstedt of a “boiling stone” [2].

Structure and Components
In a clash of scalding lava and cold seawater, zeolite forms a unique cage-like structure and negative surface charge. Aluminum and silicon make the basis of this structure, but it often includes other elements such as oxygen, tin, zinc, and titanium.
Tiny cages enable zeolite to act as a “molecular sieve,” filtering molecules based on their particle size. Negative surface charge loosely binds minerals – such as sodium, potassium, and calcium – and replaces them with large ions and heavy metals [3].
In other words, zeolite can pick up plenty of “bad stuff” and replace it with “good stuff.”
Zeolite is a mineral compound created when lava hits seawater. Its structure, primarily made of aluminum and silicon, has been likened to a “molecular sieve.”
Production
Fast forward from its re-discovery, miners are now producing around 3 million tons of zeolite each year. China leads the way, followed by South Korea, Japan, and Jordan. Natural zeolites are abundant but often contaminated with other minerals, quartz, metals, etc.
The industry mostly relies on synthetic zeolites, which are pure and have uniform structures. Some of them don’t exist in nature, such as Zeolite A.
Industrial Uses
Thanks to its unique physical properties, zeolite has found uses in [1, 3]:
Farming: removes odors and helps manage wastewater
Agriculture: controls moisture and provides minerals
Public health and ecology: purifies water and helps remove nuclear waste
Household: in deodorizing agents, cleaning products, and personal care
Chemistry: speeds up chemical reactions
Traditional & Medical Uses
Traditional medicine recognizes clay eating (geophagia) as a natural detox method. Zeolite has similar properties and traditional uses [4].
In modern medicine, doctors and researchers use zeolite for [4, 5, 3, 6]:
Separation and detection of biomarkers
Controlled drug delivery
Imaging methods such as NMR (nuclear magnetic resonance)
Skin and bone tissue engineering
Wound treatment and bleeding control
Detox Properties
Zeolite can bind and remove a wide range of toxins from the human body, drinking water, and waste materials. Its tiny cages and surface charge trap heavy metals, natural and chemical poisons, radioactive elements, microbes, metabolic products, and more [7, 8, 9, 10].
Thanks to these potent detox properties, zeolite can [3, 11, 12, 13]:
Reverse oxidative damage
Maintain a healthy microbiome
Kill bacteria and viruses
Boost the levels of minerals and trace elements
Repair skin lesions and stop bleeding
For these reasons, it’s often used to detox heavy metals and other toxins from the body.
Zeolite does it all in the gut without being absorbed, which makes it safe for human use with a few notable exceptions (see “Side Effects & Interactions” below).
Zeolite has a reputation as a detox aide because its unique surface structure binds to many potentially dangerous toxins.
Health Benefits of Zeolite
Preliminary research on zeolite showed great results, but solid clinical evidence for most conditions is still lacking. The following studies should encourage further investigation before we make any definite conclusions. Remember to speak with a doctor before taking zeolite supplements. They can not replace medical treatment for any health condition.
Note: Clinoptilolite is the most common type of zeolite for medical uses. All potential benefits refer to clinoptilolite unless stated otherwise.
Effective For:
1. Bleeding
Uncontrolled bleeding is the 2nd leading cause of death in severe injuries and accidents.
The US military uses zeolite-based product (QuickClot) to stop severe bleeding on the battlefield. Backed up by solid clinical evidence and real-life effectiveness, this product has also found application in civil medicine [14, 15, 16, 17].
Animal studies have confirmed its efficacy, too [18, 6, 19].
A mixture containing zeolite and clay (CoolClot) significantly decreased bleeding time in dogs with a life-threatening injury. In human blood samples, it enhanced clotting by 40% [13].
Clinoptilolite stopped uncontrolled bleeding in almost 70% of treated rats and increased their chance of survival by 60% [20].
Zeolite is considered an effective clotting aide to stop severe bleeding on the battlefield. Quick topical application can save lives.
Possibly Effective For:
2. Detox
Heavy Metals
In a clinical trial on 33 volunteers, zeolite enhanced the elimination of aluminum, arsenic, lead, mercury, and other heavy metals. People who took liquid zeolite (30 drops a day) had significantly higher levels of these metals in their urine samples. Lab analysis confirmed that zeolite wasn’t contaminated, attributing the results to heavy metal detox [21].
In studies on mice, zeolite enabled lead elimination and protected the brain from oxidative damage caused by this heavy metal. It reduced the levels of lead in organs by up to 91% [22, 23].
In rats, clinoptilolite stimulated aluminum detox and stopped it from reaching the blood [24].
Cadmium is another heavy metal that can cause anemia and impair different organs. In cadmium-poisoned pigs, zeolite prevented anemia and protected the liver. However, it didn’t impact the cadmium concentration in the kidneys [25].
Cell studies have confirmed the ability of zeolite to bind and remove heavy metals such as lead, arsenic, and mercury [26, 27, 28].
Brain Damage & Mood
Brain cells are particularly sensitive to heavy metal poisoning. Heavy metals can damage neurons and trigger anxiety, depression, anger, and attention problems [29, 30, 31].
The ability of zeolite to detox lead, mercury, aluminum, and other heavy metals makes it a promising complementary approach to the above-mentioned mood disorders. However, no studies have investigated the impact of zeolite on mood yet [30, 21, 23, 24].Alcohol
In 12 healthy drinkers, clinoptilolite (5 g) reduced blood levels of alcohol by up to 43%. It blocked alcohol absorption when combined with a drink [32].
In another clinical trial, 25 volunteers took zeolite (2.25 g – 4.5 g) the morning after the “night out.” It was too late for alcohol detox, but their hangover symptoms improved by 40-50% [33].
Fungal Toxins
Aflatoxins may contaminate foods and endanger human health, especially the liver [34].
Clinoptilolite was able to detox chickens from aflatoxin and protect their liver, bile duct, and kidneys. Immune system organs such as the thymus also suffered less damage [35].
Given to cows, zeolite lowered levels of aflatoxin in their milk, which is a major source of human poisoning. In test tubes, zeolite could remove aflatoxin from water (60%) and animal feed (80%) [36, 37, 38].
Zeolite protected chickens against another vicious fungal toxin, ochratoxin A. The animals ate more, gained weight, and recovered faster [39, 40].
Radioactive Elements
Zeolite porous structure is a perfect trap for large radioactive elements. In rats and sheep, clinoptilolite blocked the absorption of radioactive cesium and reduced its concentration in animals’ organs [41, 42].
Clinoptilolite can bind radioactive atoms in nuclear waste and help solve this burning ecology issue [9].
Other Toxins
Nitrates are toxins that can contaminate drinking water and disturb the health of humans and animals. In cows, zeolite reversed the metabolic damage caused by nitrates [43].
Additionally, clinoptilolite detoxed rats from organophosphates (nerve poisons). The fact that some pesticides belong to this group reveals the importance of zeolite detox properties [44, 45].
Zeolite can bind to various dangerous toxins and poisons and prevent them from being absorbed and doing damage in the human body.
3. Gut Health
“Leaky gut” means that toxins, microbes, and inflammatory molecules can leak from the gut into the bloodstream. This may cause fatigue, autoimmune diseases, depression, and more [46].
In a clinical trial of 52 endurance athletes, zeolite (1.85 g daily for 12 weeks) tightened the intestinal wall and prevented leaking. It also had a mild anti-inflammatory effect on the gut [47].
In mice with ulcerative colitis, a type of IBD, clinoptilolite was able to repair gut damage. It proved equally effective as a standard IBD drug (5-aminosalicylic acid). Tests verified that mice didn’t absorb zeolite particles into the bloodstream [48].
Zeolite showed similar action in a study on pigs with gut inflammation [49].
The buildup of urea, ammonia, and gases in the gut may lead to ulcerative colitis, IBS, and even colon cancer. High levels of urea in the blood (uremia) can be life-threatening. Zeolite binds both urea and ammonia, potentially offering protection against these gut toxins [50, 51, 52, 53, 54].
According to limited clinical evidence, zeolite may be helpful in cases of “leaky gut.”
4. Gut Microbiome
The positive impact of zeolite on gut bacteria contributes to the above benefits but also helps relieve diarrhea and improves overall health.
Cuban doctors have developed a drug for diarrhea (Enterex) made of clinoptilolite. They proved its safety and efficacy in 4 clinical trials and additional cell experiments. The ability of clinoptilolite to restore healthy gut flora played a crucial role in this effect [55].
When added to chicken feed, zeolite cut the number of harmful bacteria in their gut without disturbing the good bacteria. Chicken infected with Salmonella, a major cause of food poisonings, recovered faster and suffered less oxidative damage [56, 11, 57].
Another natural zeolite, chabazite, showed similar action in dogs. It even raised the number of probiotic Lactobacillus and Bifidobacterium strains while fighting intestinal pathogens [10].
In cell studies, zeolite inhibited the growth of 2 viral strains (coxsackievirus and echovirus) that invade us through the gut [58].
Zeolite may promote the growth of beneficial gut bacteria and inhibit the growth of pathogenic bacteria and viruses.
5. Oxidative Damage
Cigarette smoking poisons the entire body and increases the risk of cancer and cardiovascular diseases. Oxidative stress plays a key role in the adverse effects of smoking [59].
In a clinical trial on 85 smokers, clinoptilolite (5.4 g daily for 1 month) potently enhanced antioxidant defense, similar to vitamin E [12].
Other types of natural zeolite showed comparable effects in 25 people: they boosted glutathione levels and protected lipids from oxidative damage [60].
In chickens and diabetic rats, zeolite [61, 62]:
Boosted antioxidant enzymes (glutathione peroxidase, superoxide dismutase-SOD)
Increased total antioxidant capacity
Protected the organs from injury
Zeolite’s ability to bind to toxins may confer a role in combating oxidative stress.
6. May Relieve Acid Reflux and Stomach Ulcers
In gastroesophageal reflux disease (GERD), acid reflux damages the esophagus, causing heartburn and other unpleasant symptoms [63].
In a clinical trial on 25 people with GERD, clinoptilolite (1.5 g daily for 2 weeks) relieved heartburn, pain, and discomfort by 45-55% [64].
The same protocol protected another 23 patients from stomach ulcers caused by a common NSAID drug, naproxen [64].
Insufficient Evidence For:
The following purported benefits are only supported by limited, low-quality clinical studies. There is insufficient evidence to support the use of zeolite for any of the below-listed uses. Remember to speak with a doctor before using zeolite, and never use it in place of something your doctor recommends or prescribes.
7. Wound Healing
In a Russian clinical trial, zeolite enhanced the cleaning and recovery of burn wounds and improved overall complaints. Important note: patients consumed zeolite and didn’t apply it on the wounds. This study doesn’t reveal essential details such as dosage and sample size [65].
Zeolite loaded with nitric oxide (NO) boosted wound healing in rats. It killed bacteria and fungi while protecting skin cells [66].
Patches with faujasite (natural zeolite) and copper showed similar effects. They also enhanced oxygen supply and skin regeneration [67, 68].
Another excellent combination for wound healing may be zeolite + silver. Patches with silver-zeolite can inhibit the growth of dangerous microbes, such as [69, 70, 71]:
P. aeruginosa, which can cause hospital-acquired infections
E. coli, known for causing ulcers and infecting wounds
S. aureus and MRSA, hard-to-treat strains of bacteria
Candida albicans
Because of its blood clotting and antibacterial activity, some researchers have been investigating whether zeolite can help with wound healing.
8. Cholesterol and Blood Lipids
In a clinical trial on 41 patients, micronized (fine-ground) zeolite lowered blood levels of the “bad” cholesterol (LDL) and blood lipids, while raising the “good” cholesterol (HDL). After 8 weeks (6-9 g daily), these values improved by 20-25% [72].
The lack of a control group in this study prevents us from drawing reliable conclusions.
9. Oral Hygiene
In 11 volunteers, a mouth rinse with silver-zeolite (zeolite packed with silver ions) greatly reduced dental plaque formation [73].
In a cell study, silver-zeolite cut candida growth and acid production, two major causes of dental plaque and oral infections [74].
Additionally, zeolite can eliminate volatile odors and thus combat bad breath [75].
10. Liver Protection
The antioxidant power of zeolite may be crucial for liver protection.
In rats with partially removed liver, clinoptilolite provided antioxidant support by boosting glutathione and protective enzymes. As a result, blood markers of oxidative damage dropped [76].
In a cell study, clinoptilolite reversed the liver-damaging effects of adriamycin, an anticancer drug. It suppressed inflammatory proteins (NF-κB, TNF-alpha, and IL-1B) and prevented cell death [77].
As described above (see “Detox”), zeolite also protects against liver-damaging aflatoxins.
Zeolite’s antioxidant activity and ability to bind toxins may give it a role in liver health.
Benefits of Zeolite for the Skin
Due to its detox and antibacterial properties, zeolite may benefit the skin in different ways. Many would-healing and personal care products have zeolite as their main ingredient.
11. Personal care
In a clinical trial on 39 volunteers, deodorant spray with 10% silver-zeolite showed a strong and lasting (24 h) effect against armpit microbes, which produce unpleasant odors. A spray with a control substance failed to achieve this [78].
In cell studies, zeolite eliminated viruses and volatile odors. It stopped the growth of the HSV-1 (Herpes simplex) virus, which causes cold sores [75, 58].
Zeolite forms a protective film on the skin, acting as a natural sunscreen. In one cell study, zeolite even reversed oxidative damage triggered by another sunscreen ingredient, titanium-dioxide [79].
These properties make zeolite a central ingredient in various personal care products, most of which are available on the market.
12. Inflammation and Allergies
In mice, a mixture of natural zeolites trapped histamine and other triggers of inflammation, decreasing skin swelling by 57% [80].
One cell study verified the ability of zeolite to bind histamine and thus relieve inflammation and allergic reactions [81].
Air pollutants may trigger inflammation, allergies, and autoimmune issues. Since zeolite can bind to toxins and heavy metals, it might reduce the detrimental impact of pollution on the skin too.
In animals and cells, zeolite has shown the potential to reduce skin inflammation and bind to histamine.
Cancer Research
The findings discussed below stem from animal and cell-based studies. They should guide further investigation but shouldn’t be interpreted as supportive of the anticancer effects in humans until more research is done. Zeolite supplements aren’t approved for cancer prevention or treatment [82].
According to a review of studies on animals with different types of cancer, zeolite may [83, 84]:
Shrink tumors and prevent their growth
Improve overall health and prolong the lifespan
Boost the effects of chemotherapy
Both oral and skin treatment showed the above benefits.
Clinoptilolite cut the number of melanoma (skin cancer) metastases in mice and boosted their immune response [85].
In cell studies, zeolite loaded with an anticancer drug (5-fluorouracil) was able to kill stomach and colon cancer cells. Adding zeolite enhanced the potency of this drug [86, 87].
The ability of zeolite to bind radioactive elements, fungal toxins, and other cancer-causing substances also makes it a promising candidate for future cancer research.
Zeolite Side Effects
The list of side effects below is not a definite one, and you should consult your doctor about other potential side effects, based on your health condition and other factors.
In clinical trials, zeolite caused no significant side effects [47, 64, 72, 12, 60].
One safety review also found no dangers related to zeolite consumption. That said, human and animal trials revealed it can cause lung inflammation and damage when inhaled [89, 90].
Since zeolite binds heavy metals and other toxins, some people voiced concerns about potential poisoning from contaminated supplements. However, zeolite has a high affinity for those toxins and keeps them trapped under all conditions [91, 92, 4].
In one study, large amounts of zeolite in chicken feed caused gut inflammation. Rough-ground zeolite (large particles) reduced the number of blood cells in mice [93, 94].
IMPORTANT: Only certain types of natural zeolite are suitable for human consumption. Others, such as erionite, may even be cancerous [95, 96].
No studies have confirmed the safety of zeolite in children, pregnant or breastfeeding women. These groups may want to avoid it just in case.
Zeolite is generally considered safe, but animal studies have indicated the potential for gut inflammation. Furthermore, the safety profile of zeolite is incomplete in pregnant women and children.
Food and Drug Interactions
Food
Zeolite’s super-binding properties come with a price. Although it prefers heavy metals and environmental toxins, essential nutrients may also end up trapped inside its tiny cages.
In a study on pigs, clinoptilolite blocked the absorption of protein from food. Zeolite A (synthetic) decreased blood levels of calcium, phosphorus, iron, and other minerals [97, 98].
Most other studies didn’t observe nutritional deficits.
Drugs
Supplement-drug interactions can be dangerous and, in rare cases, even life-threatening. Always consult your doctor before supplementing and let them know about all drugs and supplements you are using or considering.
Zeolite binds complex organic toxins but also drugs with similar structures. For example, it can remove antibiotics, which is great for water purification but dangerous if you’ve been prescribed antibiotics. The same goes for supplements and drugs with iron [98, 99].
Zeolite may change gut pH value (acidity) and thus interfere with different medications, especially with controlled release dosage forms [100].
In one study on mice, immunostimulatory effects of zeolite provoked a graft-vs-host reaction, which can be detrimental after organ transplantation. Hence, zeolite shouldn’t be used after transplantation or combined with immunosuppressants [85].
To stay on the safe side, make sure not to combine zeolite with any drugs or supplements.
Zeolite could potentially bind to and inactivate prescription medications. It should therefore not be combined with any drugs.
Takeaway
“Zeolite” stands for volcanic minerals that form in the contact of molten lava and (sea)water. Thanks to their structures, these minerals can bind a wide range of environmental toxins and metabolic products.
Clinoptilolite is the most common natural zeolite with potential health benefits. It may help you detox, boost your gut health, stop bleedings, and combat free radicals. The evidence is insufficient when it comes to liver protection, anticancer effects, and Alzheimer’s disease.
Zeolite is safe for human consumption but can damage the lungs if inhaled for a longer time. Children and pregnant women may want to avoid it. Don’t combine zeolite with any drugs or supplements, and make sure to consult your doctor first.
Antibacterial and detox properties of zeolite can benefit the skin, too. Available products include wound dressings, deodorants, soaps, toothpaste, face masks, and more.
