What is the difference between zeolite powder and activated zeolite powder?

Both our zeolite powders, natural and activated, come from the same source and are the same micron size. We “activate” the zeolite powder that goes into the capsules and the 200 g jars of activated zeolite powder to make it easier for sensitive and very toxic people to process the zeolite. 

All clinoptilolite zeolites are hydrated aluminosilicates, which means they contain water within their structure. All water contains naturally occurring microbes.  The water and microbes are removed in a four-stage heating and cooling process.

Activating zeolite powder in this way gives it more surface area for the detoxifying cation exchange to take place. It also removes the microbes. Activated zeolite powder is your best choice if you are sensitive or very toxic.

Is your zeolite micronised or milled?

Yes it is. Micronisation is the process of reducing the average diameter of a solid material’s particles. Milling and grinding are the traditional techniques. Our zeolite undergoes a final process of air separation to ensure only the finest particles are retained. This process does not change the cubic/blocky particle shape whereas the alternative TMAZ process changes the particle shape to sharp and pointy, which should be avoided.

Is ‘nano zeolite’ more effective than Australian Certified Organic zeolite?

Natural zeolite (clinoptilolite) does not have to pass through the blood brain barrier to detoxify heavy metals and other toxic matter from the whole body. Zeolite powder is known to be safe and effective and many peer-reviewed medical studies have been published on the subject. Nano-sized zeolite remains untested.

Is it safe to ingest synthetic zeolite?

Synthetic zeolite is not safe to ingest in the long term because it releases aluminium into the body where it can accumulate. This does not occur with natural zeolite.

It states in the Critical Review on Zeolite Clinoptilolite Safety and Medical Applications in vivo:

“ … aluminum from the clinoptilolite materials does not enter the blood or accumulate in the body …”

“… aluminum released into systemic circulation was observed only in rats supplemented with synthetic zeolite A. The latter effect was attributed to the zeolite A lower stability in the acidic pH relevant for the human intestine in comparison to clinoptilolite materials.”

“In this study, authors also proved that clinoptilolite materials were efficient in the removal of aluminum from aluminum chloride-intoxicated rats in vivo. These observations may be attributed to the clinoptilolite stability …”


What happens when you take zeolite powder?

Zeolite captures and removes a wide range of heavy metal ions so when you take zeolite powder internally, it travels through the gastrointestinal tract collecting and binding these heavy metal ions and other toxins on the way. As it passes through the gastrointestinal tract, zeolite exchanges cations. According to Dr David Tomlinson BA BSc (Hons 1) PhD CChem MRACI MAIAST MAIFST, the Scientific Advisor at CMZ*:

“CMZ is a sodium zeolite. In the gastrointestinal tract CMZ binds to positively charged molecules including some toxins, and exchanges a sodium ion for each molecule bound. If the zeolite has been in the stomach at acid pH of 1 for any period of time the sodium ion would have already exchanged with an Hydrogen ion. After it has passed through into the alkaline part of the small intestine, the zeolite most likely would have reverted to the sodium form or may be binding an ammonium ion say, after digesting a meal.”

“From this it can be seen that heavy metals do not pass into the body from zeolite, as some people suggest, as Australian zeolite exchanges a sodium ion, not a heavy metal ion, for each molecule bound. I don’t know which ions are exchanged by American, Asian and European zeolites but they wouldn’t be heavy metal ions because that’s not the way zeolite works.”

Zeolite also removes heavy metals and other toxic matter from the parts of the body where it has been stored. I asked David Stevens, who at the time was completing a post graduate course in Medical Physics at the ANU in Canberra, to describe the process to me and he said:

“Most transportation in the body is the result of diffusion, where materials pass through membranes in the direction from higher concentration to lower concentration. Large particles can’t travel through cell walls, however atoms and molecules can. Heavy metals will pass from higher concentration to lower concentration (for example from bone into blood) until the concentration reaches an equilibrium (same concentration in the blood as in the bone).”

“The same thing happens between the blood and the gastrointestinal tract. A high concentration of heavy metals in the blood will pass through the blood vessel walls into the gastrointestinal tract as long as the concentration is lower in the gastrointestinal tract. Now, if the zeolite in the gastrointestinal tract adsorbs the heavy metals (which it does), the heavy metals are removed from the tract, leaving a low concentration there (in fact zero concentration), so more heavy metals pass into the gastrointestinal tract from the blood, thus removing them from the blood stream, so then the heavy metals pass from the bone (higher concentration) into the blood-stream (lower concentration).”

* CMZ is the source of our Australian Organic Certified zeolite powder.

Does zeolite remove heavy metals from all over the body?

While zeolite powder is travelling through the gastrointestinal system, it draws heavy metals and toxic matter into its structure. Zeolite draws toxic matter from other parts of the body by diffusion. Please click here for further information.

Is the Aluminium Content of Zeolite Harmful?

Zeolite is an aluminosilicate. Aluminium forms part of the zeolite structure but it is permanently bonded into the structure, making it unavailable and therefore harmless. Without the imbalance caused by the presence of aluminium, zeolite would not have the capacity for cation exchange and would not be able to take up heavy metals or other toxic matter.
The following information comes from the Critical Review on Zeolite Clinoptilolite Safety and Medical Applications in vivo:

In vivo, the acid concentrations of the intestine are substantially lower than those used in industrial activation process. For instance, gastric acid in the stomach contains HCl at 0.05–0.1 M. In such an environment, a certain release of Al species from the clinoptilolite surface may well be hypothesized even though aluminum from the clinoptilolite materials does not enter the blood or accumulate in the body as shown in athletes supplemented with zeolite-clinoptilolite supplement (Lamprecht et al., 2015) or healthy rats supplemented with different clinoptilolite materials (Kraljević Pavelić et al., 2017) where aluminum released into systemic circulation was observed only in rats supplemented with synthetic zeolite A. The latter effect was attributed to the zeolite A lower stability in the acidic pH relevant for the human intestine in comparison to clinoptilolite materials. In this study, authors also proved that clinoptilolite materials were efficient in the removal of aluminum from aluminum chloride-intoxicated rats in vivo.


Should I be concerned about the lead content in zeolite?

Zeolite contains heavy metals like lead and cadmium, that’s because that’s what they do … take up heavy metals but then they bind them so they are permanently unavailable. This means when you take zeolite you are not eating lead, cadmium, etc. The whole intact zeolite particle passes through your gastrointestinal tract gathering more heavy metals and other toxic matter as it goes.

Will taking zeolite deplete minerals from my body?

No, zeolite has a negative charge which attracts positive charged toxins. Calcium, magnesium and other nutrients are not positively charged so will not be taken up by zeolite.

Does zeolite contain minerals useful for maintaining good health?

The minerals which compose zeolite’s structure are permanently bonded within that structure and are not available to the body as a mineral supplement.

Will zeolite affect titanium implants in the body?

Zeolite will not travel through the body to remove titanium.

What is the daily dose for diabetes?

Overseas trials have shown that zeolite powder can help to regulate blood levels and can decrease the complications of diabetes. The best advice would come from a health practitioner who is familiar with zeolite as the dosage would differ depending on general health and weight.

Will zeolite remove fluoride from my body?

If you search this subject, you may find articles about a synthetic zeolite taking up fluoride but I can’t find any scientific evidence showing that natural clinoptilolite takes up fluoride, even though some people say that it does so.

Do you sell liquid zeolite?

No, we don’t sell liquid zeolite as it is not good value. Instead we sell the finest quality zeolite powder which you can mix with water to make your own liquid zeolite.

To make the equivalent of five bottles of liquid zeolite (one bottle contains approx 500 mg), add 1 level teaspoon Australian zeolite powder (2500 mg) to a large glass of water, stir.

Is your zeolite “micronised”?

Yes, even though we describe it as superfine it can also be described as micronised which means “to break into very fine particles”.

Do you clean your zeolite?

No, there is no need to clean Australian zeolite as it doesn’t contain dissolved salts. The companies who say they clean their zeolite would be supplying much younger zeolite which still contains dissolved salts, making cleaning necessary. Australian zeolite is ancient (more than 300 million years old) and time has naturally removed any dissolved salts which may have been present within its structure when it was much younger.

What is the difference between zeolite and bentonite clay?

Bentonite is an aluminosilicate and is described as a swelling clay. It has a two dimensional sheet structure into which toxic matter is absorbed. Its cation exchange capacity is (from memory) an average of about 60 meq/100 g and its pH level is approximately 10. Taking bentonite clay may give you a bloated feeling in your stomach as the clay swells in size on contact with water.

Zeolite is a hydrated aluminosilicate. It has a three dimensional structure. Each grain is riddled with tiny pores and channels where water is captured along with toxic matter. It is a lot more powerful than any clay, having an average cation exchange capacity of 150 meq/100 g. Its pH is 7.4.

Is your zeolite powder self-heating?

No, Australian zeolite is not self-heating as it is a sodium zeolite. Calcium zeolites from overseas are considered to be self-heating.

Is there any difference between the capsules and the powder?

The zeolite powder in the capsules has been “activated” by a process of heating and cooling which removes the water from the channels inside the zeolite to give more surface area for cation exchange to take place.

Is the micron size of the zeolite powder important?

Regardless of its particle size, zeolite travels through the gastrointestinal system and does not travel through the cell walls or into any other part of the body. An exception to this rule is nano-sized zeolite which would be small enough to do so but not enough is known about what would happen if this occurred. The only nano-sized zeolite I know of is produced in the Netherlands.

Is long time exposure to heavy metals linked to diabetes and obesity?

The Diabetes and the Environment Organisation provides information which
indicates that this may be true. Here is a link to the article:

What is the CEC of your zeolite?

Cation exchange capacity is measured in meq/100 g. When the tests to assess the CEC rating are carried out they are carried out over a range of time periods, from a minute or so to an hour. About 10 readings are taken and then they are averaged. Our CEC is an average of 150 meq/100g. When the CEC tests were carried out on our Australian zeolite the top readings over short periods were over 200. Always ask a supplier for the average reading.

There are more ways to rate a zeolite's quality other than just looking at the CEC. Mineralogy and stability are extremely important. Zeo Natural's zeolite is 85% clinoptiloliote and 15% mordenite, both of which are therapeutic. Stability is measured on the Moh scale which measures hardness. Our zeolite is hard at around 5 Mohs whereas US and Asian zeolites are much softer, and therefore not as stable, at around 2 Mohs.

What does zeolite powder detoxify?

Zeolite powder is a heavy metal binder. It will bind and remove a wide range of heavy metals, chemicals and VOCs. Zeolite powder is a very safe way to detoxify mercury, lead, aluminium, cadmium and other heavy metals.

Does zeolite remove parasites?

The information we have on parasites and zeolite is the quote below from a scientific study on animals. At this stage we cannot find any evidence that there have been studies on humans.
6. Impact on parasite infections
Considering the potential efficacy of zeolites against parasite infections, the results of the experiments first conducted in rats were encouraging for their use in other animal species as well. According to Wells and McHugh [127], the administration of clinoptilolite at the rate of 10% of a conventional diet facilitated the removal of parasites from the intestinal lumen of rats infected with the nematode Nippostrongylus brasiliensis.
