Despite years of medical advances, cancer remains one of the leading causes of death worldwide, with millions of people diagnosed and dying each year. In Hungary alone, cancer is called tens of thousands of lives each year. Although many treatments have been introduced, the improvement in the time people usually survive after diagnosis remains moderate. In response, researchers have been looking for new ways to support standard cancer care. One of these methods is to change the balance of natural hydrogen in the body by lower hydrogen in drinking water, called deuterium, a stable hydrogen isotope that contains neutrons in addition to the usual protons. This approach may offer promising new directions in cancer treatment.
Dr. Gábor Somlyai, a scientific team at HYD LLC, and his co-authors, have collaborated with Szeged University to publish a new study. This milestone is achieved after 35 years of research and international scientific cooperation. The publication evaluates clinical data and examines how this unique water in conventional cancer therapies affects patient outcomes. Their results are published in the Journal of Medicine Biomedicine. The team reviewed experiences from a large number of Hungarian cancer patients who drank the dehydrated water while receiving traditional treatments. Their research is particularly important because it relies on real-world data, which means that actual patient experiences outside of clinical trials have been collected over more than three decades.
The results show that the patient’s lifespan is significantly longer. On average, those who drink this special water have a lifespan of more than five times the national average. Even when they start drinking water, they survive much longer than expected. For those who still have cancer when they start drinking water, their results are still much better than usual. Those who are already in relief, which means that cancer is not active at the moment and when they start drinking water, the cancer lives significantly longer, suggesting that this may help prevent cancer recovery.
“Using water with lower deuterium levels allows us to interact with very basic levels of cellular function, which opens the door to new types of treatment and better understand how cells perform,” explains Dr. Somlyai. In short, this approach involves reducing the amount of deuterium in the body, which is believed to help slow or stop cancer cell growth.
The idea is based on the observation that the higher deuterium to hydrogen ratio appears to send signals that make cancer cells grow. Normal drinking water has more deuterium than this special water. Early experiments with animals and cells in the laboratory showed that lowering deuterium levels could prevent tumor growth. Tumors are tissue abnormalities caused by uncontrolled cell growth. This large-scale study now shows similar results for actual patients, supporting the idea that drinking deuterium-sinked water can help people when added to standard treatment.
Researchers also found that how long people drink water and how long after the diagnosis are important. Those who drink for several months and start shortly after being diagnosed have the best results. “Patients who started drinking within a few months of diagnosis always showed strong survival results,” Dr. Somlyai noted.
Dr. Somlyai and his team made it clear that poor water cannot replace standard treatments such as surgery, chemotherapy or radiation. Chemotherapy is a drug treatment that uses powerful chemicals to kill cells growing rapidly in the body, while radiation therapy uses high-energy particles or waves to destroy or destroy cancer cells. Instead, it works with them to help patients do better. Even for patients with advanced cancer, there will be no serious side effects. In fact, water appears to reduce some of the harmful effects of chemotherapy and help patients feel better overall. Details of the protocol used can be found in the book of Dr. Somlyai.
Dr. Somlyai summed up the potential of this approach, believing that this unique water was introduced early and used regularly, and that it could significantly reduce cancer deaths. This could mean saving many lives every year. The study has a great reason for conducting more large-scale testing and considering water as a useful supplement to existing cancer treatments. To achieve this, Dr. Somlyai’s team aims to develop registered medicine in partnership with investors and pharmaceutical companies.

About the Author
Gaber Solei In 1982, he graduated from Szeged University biologist between 1982 and 1990. From 1983 to 1986, he received a scholarship from the Hungarian Academy of Sciences, serving as a graduate student and earning a doctorate. In 1988, he defended his paper on molecular biology. That same year, Dr. Somlyai stayed at Georg-August University in Göttingen for six months and received a DFG scholarship. Starting from the end of 1988, he held a postdoctoral fellowship at the University of Missouri (USA), where he worked in genetic engineering and genetic maps.
After Albert Szent-Györgyi, a scientist at the Hungarian Nobel Prize winner – he said the real cause of cancer should be searched on a molecular level – Dr. Solei began surveying senior researchers at the Hungarian Institute of Oncology in 1990 to study the biological importance of naturally occurring belonging to Botteber.
In 1993, he founded Hyd LLC. Anticancer research and drug development are carried out according to proprietary procedures for deuterium depletion. Between 1993 and 1997, he was the scientific director of Hyd Ltd. and since 1997 he became CEO of the company. He has been the president of Hyd Pharma Co since 2012, Hyd Pharma Co. Hyd LLC’s parent company.
In 2000, his book “Defeat Cancer”! Appeared in Hungary. Since then, it has been published in Romania, Japan, the United States, South Korea and China. In 2021, his second book, Deuterium Depletion – A New Way to Cancer Treatment and Health Preservation, appeared in Hungary in print and e-book form. Since then, the book has been published in English, Chinese, Japanese and German. Gábor Somlyai has written many scientific publications and is a recognized speaker at international conferences. Gábor Somlyai is the inventor of numerous international patents granted by most developed countries.
