FAQ

Zeolite is a natural volcanic mineral that was formed millions of years ago when glowing lava flowed into the sea. This created tiny cavities and channels in the rock - a microporous structure that makes zeolite an extraordinary mineral. It can bind pollutants, release minerals, and act as an ion exchanger (i.e., exchanging harmful substances for useful minerals). The most important natural type of zeolite for humans, animals, and soil is clinoptilolite zeolite.

Three things differentiate us: raw material, milling process, and control.
Our clinoptilolite comes from the best mining region in Europe — Eastern Slovakia — and is not blasted, but gently extracted. It contains at least 80% pure clinoptilolite.
The milling process is crucial: We use Air2Air Activation Technology — a tribomechanical process in which zeolite particles collide with each other due to airflow and grind themselves. No metal abrasion, no crushed crystal lattices. The result: an average particle size of 14–35 µm and an active surface area of over 600 m² per gram.
Everything is in one hand — from production to you. We are regularly inspected unannounced by the Austrian feed authority.

It's simple: the magnet test. Put zeolite in a glass of water, stir, and hold a magnet to the outside of the glass. If a black cloud forms—these are metal impurities from incorrect grinding. You don't want such zeolite in your body, on your skin, or in your animals' feed.
Many products are advertised as "ultra-fine"—always check the actual particle size (d50 value). A product with a d50 = 95 µm is not ultra-fine, even if it is advertised as such. STEINKRAFT zeolite has a d50 value of 14 µm.

Yes. Clinoptilolite zeolite is 100% natural, without chemical additives and generally compatible with organic farming.
As a feed additive, it is approved throughout the EU under the identification number E568 — confirmed by EFSA opinions 2012 and 2013. For the exact classification in your own operation, we recommend consulting with the responsible organic control body.

Preferably in BPA-free plastic containers or glass containers. Zeolite is hygroscopic (= absorbs moisture) — therefore, never store it in paper bags. Store in a dry, cool place, protected from light. When stored correctly, zeolite has an almost unlimited shelf life.

The Swedish mineralogist Axel F. Cronstedt first described zeolite in 1756. He observed that the mineral began to bubble when heated — and therefore named it zeolite (= boiling stone, from the Greek zein = to boil, lithos = stone). Zeolite became known worldwide after the Chernobyl reactor disaster in 1986 — at that time, about 500,000 tons of natural zeolite were used for decontamination.

STEINKRAFT offers specific products for dogs (DOGKRAFT) and cats (CATKRAFT). Zeolite supports digestion, detoxification, and general vitality – as a feed additive mixed into the food.

As a general guideline: 0.5% of the daily feed amount, maximum 1%. Start with half the amount and gradually increase to the full dosage within 5–7 days. Important: Always provide plenty of fresh water. DOGKRAFT Zeolite has an average particle size of 14 µm — so you need less than with coarser products.

Zeolite should be administered at least 2 hours before or after medication, as it can bind active ingredients from medications. For chronically ill animals, always consult with a veterinarian.

Yes. Zeolite can also be given to cats—either in their drinking water or mixed wet with their food. Cats are often pickier than dogs; administering it with drinking water is usually easier. Please contact us for a customized dosage recommendation.

For skin and mucous membranes (= moist tissue layers in the mouth, on the tongue, in the throat), the following applies: below 10 µm (micrometer = thousandth of a millimeter). Coarser powders can have an abrasive effect on sensitive areas and also do not penetrate deep enough into pores and skin structures.

LIFEKRAFT Zeolite has an average particle size of 8 µm – which is fine enough for daily oral hygiene, face masks and application on the oral mucosa. Important: Only use products under 10 µm for these applications

Yes – as a peeling, as an additive in your day cream or as a mouthwash, it can be used daily without problems. We recommend the face mask 1-2 times a week. The detox bath once a week. You can use zeolite as a foot powder or deodorant as often as you like.

The simplest option: Mix 2 tsp of LIFEKRAFT Zeolite powder with a little water or chamomile tea to form a creamy paste. Apply to cleansed face, leave on until dry (approx. 10–15 minutes), gently wash off with warm water. Then finish with a cream.

You can also add honey, aloe vera gel, yogurt, avocado or turmeric – depending on your skin type and concerns.

and has no mint flavor – you get used to it surprisingly quickly. Afterward, your teeth feel unusually smooth.

If you don't want to miss the mint flavor: simply add a pinch of zeolite to your toothpaste. Both work.

Important: Always spit it out, do not swallow – the zeolite has absorbed bacteria and toxins, which should leave the body.

Zeolite acts on the main causes of acne: excess sebum (= oily secretion of the sebaceous glands), bacteria, and inflammation. Its microporous structure adsorbs (= binds to the surface) excess oil directly from the pores. At the same time, bacteria like Staphylococcus aureus bind to the zeolite surface.

There is no large-scale clinical study exclusively on zeolite for acne – but its active properties are scientifically proven, and many customers report significantly clearer skin after regular mask application.

No – provided you use zeolite with a grain size under 10 µm. LIFEKRAFT zeolite with 8 µm is not abrasive to tooth enamel. On the contrary: the silicon it contains and the ion exchange (= exchange of charged particles between the mineral and the environment) can remineralise (= restore minerals to) and strengthen tooth enamel in the long term.

Many of our customers report this – and it makes scientific sense. Zeolite has an antimicrobial effect (= acts against bacteria) and binds inflammatory mediators (= substances that trigger and amplify inflammation). Regular brushing with zeolite and targeted application to inflamed areas can soothe the gums and support natural healing

An animal study (Turkoglu et al., 2024) showed that tribomechanically activated clinoptilolite powder was as effective in reducing inflammatory skin reactions as standard medical therapy – without side effects. While clinical studies in humans still need to confirm this, the results are promising.

For sensitive skin: Zeolite with 8 µm is gentle enough for daily use. As a bath additive (2 tablespoons in a full bath), it has a particularly soothing effect – zeolite noticeably softens the water through ion exchange.

Dissolve 1 level teaspoon of LIFEKRAFT Zeolite Powder in 125 ml of water, stir well. Take a sip, rinse and gargle for 1–2 minutes, then spit it out. Repeat with the next sip, for a total of 3–5 minutes.

Best done first thing in the morning after waking up – we detoxify intensively overnight through the oral mucous membranes, and these substances should be removed as early as possible.

Yes – zeolite is very compatible with aloe vera, chamomile tea, coconut oil, jojoba oil, honey, turmeric, and other natural ingredients. If you use medicinal skincare products – for example, retinoids (= vitamin A derivatives for acne treatment) or benzoyl peroxide (= antibacterial active ingredient against acne) – please briefly ask your doctor, not because zeolite is dangerous, but to rule out interactions.

Zeolite itself is a natural mineral with no additives. However, special caution is advised for children: The powder should not be swallowed. For gentle external use – for example, in a foot bath or as a face mask under supervision – it is generally suitable. If in doubt, please consult a pediatrician.

The basic mineral is the same – high-quality clinoptilolite from Eastern Slovakia, tribomechanically activated by Air2Air Activation Technology. The difference lies in the grain size and declaration:

LIFEKRAFT Zeolite (8 µm) – declared as a cosmetic product, for external human use

STEINKRAFT / HORSEKRAFT / DOGKRAFT – declared as feed additive E568, for animals

Please always use the product specifically declared for the respective application area.

Zeolite can be directly incorporated into the soil (BODENKRAFT PUR powder or granules), sprayed on as a foliar fertilizer (GRÜNKRAFT), or mixed into the watering can (AM+PLUS). For raised beds, we recommend a layer of zeolite granules in the bottom layer of soil — this permanently improves water retention and nutrient availability.

As a soil amendment: work approx. 100–300 g per m² into the topsoil. In pots: 10–20% of the substrate. As a foliar fertilizer: spray diluted according to product instructions. Zeolite has a long-lasting effect — one treatment lasts for several years.

Yes. Zeolite does not weather or break down—it remains permanently in the soil and improves water retention capacity,
nutrient availability, and soil structure in the long term. A single application is effective for many years.

Yes — and it's even highly recommended. Zeolite binds the ammonia (= nitrogen) in the compost, prevents its outgassing, and makes the finished compost richer in nutrients. At the same time, zeolite buffers the moisture in the compost pile. AM+PLUS further accelerates the composting process.

No — zeolite does not replace fertilizer, but it makes fertilizer more efficient. Nutrients are bound in the soil instead of being leached out and are slowly released to the plant. In practice, this means less fertilizer for the same or a better effect. Many farmers report that they need significantly less fertilizer after zeolite treatment.

• BODENKRAFT PUR (Zeolite): Work directly into the soil with a seed drill, spreader, or cultivator — as a permanent soil improvement
• GRÜNKRAFT CALCIUM / Zeolith Pur: Spray onto leaves as a foliar fertilizer with a field sprayer or drone
• AM+PLUS: Into irrigation water (1:100), into liquid manure (0.1 L per m³), or via foliar spraying

That depends on the crop, soil, and goal. Contact us directly — we will calculate the right amount for your farm.

The fine silicate particles on the leaf surface stimulate microorganisms that absorb nitrogen from the atmosphere and make it available to the leaf. The result: dark green, lusher leaves — naturally supplied with nitrogen. In addition, the particles form a natural barrier against mites and aphids, as they mechanically disrupt their respiratory organs — without chemicals.

Lime is the engine for all other nutrients. Without the correct pH value (= acidity), plants cannot absorb fertilizer — even if it is present. Lime regulates the pH value, activates soil life, and makes nutrients available to plants. STEINKRAFT lime has a plant availability of up to 96% due to the tribo-mechanical grinding process.

AM+PLUS are active microorganisms from Austrian organic production. In arable farming, they are used for soil revitalization (1:100 with water), as a foliar spray, and for slurry treatment. They promote humus formation, make nutrients available to plants, and improve soil structure long-term. In combination with zeolite, they unleash their full potential.

Yes. All STEINKRAFT agricultural products can be used in organic production according to Regulation (EU) No. 2018/848. For the exact classification in your own operation, we recommend consulting your organic certification body.

• STALLKRAFT Litter (Zeolite + Lime + Organic Herbs): For all livestock as stable bedding — cattle, pigs, sheep, goats, poultry
• TIERKRAFT Zeolite: As a feed additive for cattle, pigs, sheep, and goats
• GÜLLEKRAFT N-FIX: For slurry enhancement — binds NH₃, reduces odor, increases nutrient content
• AM+PLUS Active Microorganisms: For stable air nebulization, slurry treatment, and feeding

Yes. Clinoptilolite-zeolite is approved as a feed additive (E568) for all animal species throughout the EU. In practice, it is successfully used in cattle, pigs, sheep, goats and poultry. The recommended dosage is max. 1% of the total daily feed intake — best mixed with moist feed.

STALLKRAFT litter binds ammonia (NH₃) directly at the source — in the manure, before it escapes into the air. This keeps the litter drier, reduces germs, improves the stable climate and protects the respiratory tracts of animals and humans. 100–200 g/m² of floor area are recommended; refresh as needed. The powder can be easily mixed with straw litter.

Zeolite binds ammonium nitrogen (NH₄⁺) in slurry and prevents its outgassing as ammonia (NH₃). The nitrogen remains bound in the slurry and is fully available to plants when applied. Result: up to 80% nitrogen utilization in the field – significantly more than without treatment. At the same time, odor pollution is significantly reduced.

Yes. Zeolite and bentonite can bind aflatoxins and other mycotoxins (mould toxins) in the digestive tract of livestock and safely excrete them. This has been proven in numerous studies for cattle, pigs, and poultry—even if the feed appears outwardly unremarkable.

As bedding in cubicles, zeolite keeps resting surfaces dry and binds ammonia. Less moisture means fewer germs and thus a positive effect on hoof health and Mortellaro. Many farmers report significant improvement after regular STALLKRAFT application.

AM+PLUS are active microorganisms (photosynthetic and lactic acid bacteria, as well as yeasts), produced by Loidholdhof in Upper Austria from organic Austrian herbs. In the stable, they are used for stable air nebulization: 0.2 liters of AM+PLUS per 10 liters of water, sprayed at least 3 times a week. This reduces odor, germs, and flies — and starts the healthy fermentation process in the manure, which significantly improves slurry quality.
