- Conclusion & Thanks to the Researchers
In veterinary medicine, the search for effective treatment methods for tumor diseases in dogs is of great importance. A promising study was conducted at the Faculty of Veterinary Medicine in Zagreb under the direction of Prof. Dr. sc. Ljiljana Bedrica. The aim of this study was to evaluate the effectiveness of clinoptilolite zeolite in various tumors in dogs. As part of the study, 51 dogs were thoroughly examined and subsequently treated with clinoptilolite.
And all these studies have, among other things, led to the approval of clinoptilolite zeolite as a feed additive. Thank you for that!
Mammary Gland Tumors
The treatment of mammary gland tumors was investigated in 10 female dogs aged 6 to 14 years. Particularly remarkable results were achieved with adenocarcinomas: smaller tumors completely disappeared after 3 to 4 weeks of clinoptilolite intake, while larger tumors shrunk to half their size after 4 weeks. Mixed mammary carcinomas showed no reduction after 3 months but remained stable. One year after the removal of these tumors, no recurrence symptoms occurred.
Skin and Mucous Membrane Tumors
Skin and mucous membrane tumors were treated in 10 dogs aged 6.5 to 13 years. All tumors disappeared after a certain period of clinoptilolite intake, but reappeared after discontinuation of the preparation. One week after resuming intake, the tumors receded again.
Prostate Tumors
The study of prostate tumors included 6 dogs. Already one week after the start of clinoptilolite treatment, the disease symptoms completely disappeared.
Lymphomas
The influence of clinoptilolite on lymphomas was investigated in 8 dogs. All dogs showed significant improvement after 3-4 days and behaved normally again after one week. After one month, their blood count had also normalized.
Lung Tumors
Lung tumors were diagnosed in 3 dogs. After one month of clinoptilolite treatment, the tumors were reduced by half. Two dogs survived another year, while one dog, who took the preparation irregularly, died after three months.
Osteosarcomas
Osteosarcomas were found in 3 dogs. One dog died two months after diagnosis, while two dogs have been taking clinoptilolite for one and a half years and are still alive.
Various other Tumors
In various other tumors, an improvement in the general condition was observed in all dogs.
Conclusion: Clinoptilolite Zeolite - Hope for Dogs
The results of this study are promising and suggest that clinoptilolite could be an effective supplement for the treatment of tumor diseases in dogs. While some tumor types completely disappeared or significantly shrank, the general health of the dogs improved in all cases. These results offer hope and open up new perspectives in veterinary oncology.

So: I found this article on Research Gate. For all who like to read the original text. Clinoptilolite zeolite was used, among other things, in 22 dogs suffering from various tumors.
Twenty-two dogs participated in the experiments. They belonged to different breeds and weighed between 3 and 42 kg. The animals were of both sexes and between 5 and 14 years old. The data for the 14 dogs in which an improvement in the disease was observed are presented in Table 2 and can be found on pages 19-21 in the study. I have linked them for you.
I have also translated the ABSTRACT of the study for you:
- "Natural silicate materials, including zeolite clinoptilolite, have shown diverse biological activities and have been successfully used as a vaccine adjuvant and for the treatment of diarrhea. We report a new use of finely ground clinoptilolite as a potential adjuvant in cancer therapy. Treatment of mice and dogs with various types of tumors resulted in an improvement in general health, an extension of life span, and a reduction in tumor size. Local application to skin cancer in dogs effectively reduced tumor formation and growth. Toxicology studies in mice and rats showed no adverse effects. In vitro studies showed that finely ground clinoptilolite inhibits protein kinase B (c-Akt), induces the expression of tumor suppressor proteins p21WAF1/CIP1 and p27KIP1, and blocks cell growth in several cancer cell lines. These data suggest that clinoptilolite treatment could affect cancer growth by attenuating survival signals and inducing tumor suppressor genes in treated cells."

I have another study here by Prof. Dr. sc. Ljiljana Bedrica. It shows how healing zeolite is on the skin of dogs after burns and, above all, how a zeolite-optimized feed supports the healing process. All scientifically conducted at the Faculty of Veterinary Medicine in Zagreb.
VIDEO: Here you can watch Professor Dr. Bedrica, veterinarian and researcher. She talks about zeolite. In her native language. For all of you who understand Croatian.
Conclusion: A Thank You to Veterinarians and Researchers
Our beloved animals are more than just companions – they are an expression of our love for life itself. The groundbreaking study on the effectiveness of clinoptilolite in canine tumors, conducted at the Faculty of Veterinary Medicine in Zagreb, gives us and our four-legged friends new hope.
Special thanks go to the dedicated veterinarians and researchers who made this pioneering work possible. Their tireless dedication and deep understanding of the needs of our animals have led to these remarkable results.
We also always thank Mr. Timohir Lelas, who prolonged the tribomechanical grinding method for zeolite, which means prolonged, he created it. or developed prototypes to maturity. And Prof. Hecht, who patiently and clearly explained to us how zeolite boosts self-regulation in the bodies of our animals. Their insights and efforts have significantly contributed to clinoptilolite being recognized as a valuable supplement in the treatment of canine tumors.
This research is a ray of hope for all animal lovers and shows how science and love can go hand in hand to improve the lives of our beloved animals. Thanks to everyone involved, and to clinoptilolite zeolite – for the hope it gives us.

Diesen Untersuchungsergebnissen wollte ich immer schon einen eigenen Blog widmen. Jetzt ist es soweit gewesen. An dieser Stelle unser Danke an Frau Doktor Vesna Lelas für ihre Forschung mit Zeolith an Hunden. Dass Zeolith unterstützend wirkt, ist mittlerweile recht bekannt. Wenn eine Untersuchung mit Zahlen vorliegt ist es dann wunderbar!
