The possible role of deuterium (heavy isotope of hydrogen) in regulating cell division, mitochondrial metabolism & cancer.

TOPICS DISCUSSED:

• Deuterium Basics: Deuterium is twice as massive as regular hydrogen; natural water contains ~150 ppm, with stronger oxygen-deuterium bonds slowing reactions compared to oxygen-hydrogen.
• Mitochondrial Role: Healthy mitochondria produce deuterium-depleted metabolic water (~110 ppm from fat oxidation vs. ~150 ppm from carbs), helping maintain low cellular D:H ratios.
• Cell Growth Regulation: Lower deuterium slows cell division in vitro; cells sense small D:H changes, with higher levels (near/above 150 ppm) promoting growth.
• In Vitro Evidence: DDW (e.g., 25-125 ppm) can reduce proliferation and alters cancer-related gene expression.
• Animal Models: DDW caused tumor regression in mice with transplanted human cancers and showed possible efficacy in veterinary use for dogs and cats.
• Human Prostate Cancer: Phase 2 randomized study showed greater Prostate-Specific Antigen (PSA) reduction, tumor shrinkage, and better 1-year survival with DDW plus standard therapy vs. placebo.
• Dietary Modulation: Ketogenic/high-fat diets lower body deuterium from lipid oxidation.
• Broader Implications: Potential in neurodegeneration models; larger trials needed for registration as adjunct cancer therapy.

ABOUT THE GUEST: Gábor Somlyai, PhD is a molecular biologist who pioneered deuterium depletion studies at the National Institute of Oncology in Hungary. His primary work focuses on the role of deuterium in living organisms and the development of deuterium-depleted water for cancer therapy.
