In the hydrogen water group, the average telomere length increased from 0.99 ± 0.15 to 1.02 ± 0.26, while in the control group it decreased from 0.92 ± 0.27 to 0.79 ± 0.15.
In the journal "Experimental Gerontology" in November 2021 (volume 155), an article titled "The effects of 6-month hydrogen-rich water intake on molecular and phenotypic biomarkers of aging in older adults aged 70 years and over: A randomized controlled pilot trial" was published.
It's important to note that the study involved human participants, not animals.
The study involved 40 elderly people aged 70 and over.
Participants were randomly divided into two groups: one drank 0.5 liters of hydrogen-rich water (15 ppm of hydrogen) daily for 6 months, while the other consumed a control drink (0 ppm of hydrogen).
The study assessed molecular and phenotypic biomarkers of aging.
In the hydrogen water group, the average telomere length increased from 0.99 ± 0.15 to 1.02 ± 0.26, while in the control group it decreased from 0.92 ± 0.27 to 0.79 ± 0.15.
Improvements in DNA methylation and increased levels of brain metabolites in certain areas were also noted in the hydrogen water group.
Physical activity, measured by a chair rise test, also improved.
The study suggests that hydrogen-rich water could be a potential anti-aging agent, affecting several key aspects of aging, including telomere shortening.
Human genome information is stored only in the DNA strand. These 2-meter-long strands are housed in the nucleus of each cell, approximately 6 micrometers in size. 1 μm is one-millionth of a meter.
To tightly pack and still provide access to the DNA information, chromosomes exist - long DNA strands are packaged and organized within them.
Telomeres are segments at the ends of chromosomes. As cells divide, the size of telomeres decreases. A popular theory is that telomere shortening is one of the causes of aging. When the telomere is completely gone, the cell dies.
One of the first articles on this site described the potential use of hydrogen as an antioxidant to slow aging processes by affecting oxidation in mitochondria. Oxidative processes in mitochondria are one of the common theories of aging.
Another, now more prevalent theory, relates to telomere shortening. This study confirms the beneficial effect of hydrogen in this aspect.
