Zeolite for Animals: Your Comprehensive Guide to Understandable and Well-Founded Information - Zeolite Knowledge for Dogs and Cats

What is zeolite?

Zeolite is a naturally occurring mineral that has formed over millennia through the reaction of volcanic ash with alkaline water. It belongs to the aluminosilicate group and is characterized by its unique crystalline structure, which makes it an effective adsorbent . This structure consists of an open network of channels and cavities that allows the zeolite to bind specific molecules and ions to its surface (adsorption).

Origin and discovery of zeolite

Zeolite was first discovered in 1756 by Swedish mineralogist Axel Fredrik Cronstedt. The name "zeolite" comes from the Greek words "zeo " (to boil) and " lithos " (stone) and refers to the mineral's ability to release water when heated. This discovery marked the beginning of zeolite's diverse applications in various fields, from water treatment to use in technological additives for optimizing animal feed . And that's what this is all about.

Structure and properties of zeolite

Zeolite's unique structure is based on a network of silicon and aluminum atoms arranged in a tetrahedral pattern. See the image above. This porous structure, with its cavities and channels, gives zeolite its ability to adsorb and bind specific molecules and ions to its surface . This property makes zeolite particularly valuable for binding and removing unwanted substances , which contributes to the optimization of feed because it binds contaminants at the surface.

There are various types of zeolites that differ in their composition and structure. For use in animal feed, a specific type of zeolite is used, which is considered particularly suitable (capable of binding the most) to achieve the desired optimization: clinoptilolite zeolite. This is also the only type approved for use as a feed additive.

Zeolite as an alternative to antibiotics in animal husbandry

In recent decades, research has increasingly focused on the use of zeolite in animals, particularly due to growing concerns about antibiotic-resistant germs . The overuse of antibiotics in animal husbandry has led to the emergence of multidrug-resistant bacteria, endangering both animal and human health. Zeolite, or clinoptilolite, offers a natural solution, as this powder acts as an antibacterial agent and can be used without the risks of antibiotic resistance.

The role of clinoptilolite zeolite in animal nutrition

Clinoptilolite zeolite is a natural mineral that, due to its unique structure, acts as an ion exchange resin and detoxifying agent . It has proven particularly effective in animal nutrition, as it promotes intestinal health and binds toxins and heavy metals, thus relieving the body of toxins. These properties make it a promising supplement for the diets of farm animals and companion animals, as it not only supports overall health but can also improve growth , feed conversion, and nutrient absorption .

Research on the benefits of zeolite

Several studies have shown that clinoptilolite zeolite can significantly improve the health benefits of animals. One study found that zeolite stabilizes the intestinal flora and possesses anti-inflammatory properties . It has also been shown to reduce tumor formation in dogs and extend overall lifespan . This demonstrates that zeolite is not only beneficial as a feed additive but also has the potential to be used as a supportive therapy for serious conditions.

Zeolite as a response to antibiotic resistance

Given the threat of antibiotic-resistant germs, zeolite is increasingly gaining attention in veterinary medicine. Clinoptilolite's ability to work without side effects such as resistance makes it an ideal alternative for combating infections and promoting animal health . The EU has already approved zeolite as a feed additive, and studies demonstrate its safety and effectiveness, particularly for detoxification and digestive support .

I've summarized the first study again in detail, for those of us who enjoy experimental designs and details, especially because this study emphasizes the safety of zeolite in its summary. Even for pregnant dogs.

Summary of the study (Januškevičius et al. 2013): Investigation of the influence of zeolite on the digestion and health of dogs

Experimental setup

• Number and type of dogs: A total of 10 adult female German Shepherds were examined. All dogs were 2–4 years old, weighed approximately 25–30 kg, and were clinically healthy. .

• Study duration: The study extended over several months , from the bitches' resting state through pregnancy and into the lactation phase . Initially, the bitches were observed in the non-pregnant state (resting phase), then in the middle of their approximately 63-day pregnancy, and finally in the middle of their lactation period. During the entire period, the dogs received the food assigned to them (with or without zeolite supplement) depending on their group.

• Zeolite type and quantity: Clinoptilolite (a naturally occurring zeolite) was used as the zeolite. The dosage was 1.5% of the feed (based on dry matter) in the test group's diet. The zeolite powder was mixed into the commercial complete feed (a dry feed with ~24% protein, 13% fat, 3% crude fiber, and ~14.7 MJ/kg energy). .

• Aim of the study: To investigate the influence of zeolite on the digestion and health of dogs. In particular, the aim was to examine how the addition of clinoptilolite to food affects the stool consistency , nutrient intake (digestibility of the food), and selected blood values ​​of the dogs. The bitches were observed in different physiological phases (rest, pregnancy, lactation) to determine possible differences depending on the condition .

• Control and test groups: The dogs were divided into two groups of 5 animals each .
  Control group: received the normal complete feed without zeolite supplementation . Test group: received the same feed, but with 1.5% clinoptilolite added. Both groups were kept under identical conditions to clearly attribute any differences to the feed supplementation.
  

  Key findings of the study: Zeolite in dogs

  • Stool consistency: The zeolite-fed dogs had firmer stools than the control dogs. Specifically, the zeolite group's stools were drier (less moisture) —about 2–3% more dry matter than the control group in all phases. This effect was evident both at rest, in mid-pregnancy, and during lactation. The zeolite-treated dogs' stools were more compact and had a less odor than those of the control dogs. .

  • Nutrient utilization: The addition of 1.5% zeolite led to slightly improved digestibility of some nutrients. During the non-pregnant state (resting phase), dogs in the zeolite group were able to absorb slightly more nutrients from the feed than the control dogs—for example, approximately 1–3% higher absorption rates for organic matter, crude protein, and nitrogen-free extractives (carbohydrates). During pregnancy, there were hardly any differences between the groups (zeolite showed no significant effect on nutrient intake). During the lactation period, zeolite again improved the digestibility of certain components: in particular, more total dry matter (+5%) and minerals (crude ash, +2%) were absorbed from the feed in the zeolite group than in the control group. Overall, these improvements were moderate but showed a trend toward more efficient feed utilization with zeolite supplementation.

  • Blood values ​​and health: No adverse health effects occurred – all blood values ​​measured in the dogs remained within the normal reference range. However, slight beneficial changes in some blood parameters were observed in the zeolite group. After two months of resting feeding, the zeolite-fed bitches had higher total protein levels in the blood (+5.6%) , lower blood sugar levels (-16%) , and lower cholesterol (-5%) compared to the control group. Calcium levels were also increased (+13%) compared to the control group. Similar trends were observed during lactation: in the middle of the lactation period, the total protein in the blood of the zeolite dogs was highest (around 67 g/L, ~6% more than in the control animals) and their glucose and cholesterol levels were lower .

  • All of these differences were statistically significant but remained within the physiologically normal range. During pregnancy, the blood counts of the two groups differed little , and no abnormalities were observed.
    In summary, the blood analyses indicated that the zeolite supplement is well tolerated and contributes to an improved metabolic state (higher protein and calcium, and fewer “stress” parameters such as glucose and cholesterol). .

  Relevance for dog owners

  For dog owners considering using zeolite to support their pet's well-being , this study provides some useful guidance. It's positive to note that the clinoptilolite supplement (1.5% of the feed) was well tolerated : The dogs remained healthy, and there were no negative effects on their blood counts or behavior. On the contrary, the zeolite demonstrated certain beneficial effects : The dogs had firmer, less odorous stools , which indicates improved digestion and can make everyday tasks easier, for example, with stool intake or disposal. Furthermore, more efficient nutrient utilization was observed, meaning the animal utilized its food better. Slightly elevated protein and calcium levels in the blood of the zeolite-treated dogs indicate that nutrient supply or metabolism is being supported. Also good. And during the rest period, the test group dogs had fewer stress markers in their bodies. That's really perfect.
