Chronological age counts the years. Biological age tells you how your body is actually functioning — years younger, or older, than your ID says.

No. A simple finger prick, done yourself, at home.

Yes — that's the whole point. One test is a snapshot. Every 3–6 months shows the trend.

Our team walks you through what it means, and what's worth discussing with your doctor.

No. Only DNA methylation — never your genetic code.

Saliva is easier to collect, but blood gives a more reliable read. Saliva samples contain a mix of cell types that can vary from person to person and day to day, which can shift the result. Blood-based testing — even from a simple finger prick — gives a cleaner, more consistent sample to measure against. That's why Oritov Age: Chronos R uses a finger prick rather than saliva: the ease of at-home collection, without the trade-off in reliability.

Blood tests can provide useful information, but they do not always give a complete picture of your vitamin and mineral status. Some nutrients are distributed differently throughout the body, meaning a blood measurement may not necessarily reflect what is available at the tissue or cellular level.

The same principle applies to many conventional health biomarkers. A result can fall within a laboratory’s “normal” range without necessarily reflecting what is optimal for long-term health. Reference ranges are generally based on population data and clinical thresholds, rather than defining an individual’s ideal level for healthy ageing.

Genetic testing has similar limitations. Looking at a small number of genetic variants cannot capture the full complexity of how multiple genes and other biological factors interact. A single genetic result therefore provides only one piece of the picture.

This is why we believe no single blood marker or genetic variant can fully describe how your body is ageing. A broader view of your biology can provide additional context beyond conventional measurements alone.

Biological age testing offers another perspective — looking at patterns across multiple biological markers rather than relying on one nutrient, biomarker or genetic variant.

Your chronological age is simply the number of years since you were born. Your biological age reflects patterns in your biology that may differ from your chronological age.

Epigenetic clocks estimate biological age by examining DNA methylation — chemical changes that help regulate which genes are active or inactive. These methylation patterns change over time and can also be influenced by factors such as lifestyle and environmental exposures.

An epigenetic clock analyses methylation at specific locations across your DNA and uses mathematical models to estimate biological age or other aspects of the ageing process.

This provides a different perspective from conventional health checks. Blood tests can measure individual biomarkers such as cholesterol, inflammation or kidney function, while an epigenetic assessment looks at broader patterns associated with biological ageing.

In simple terms: your chronological age tells you how long you have been alive. An epigenetic clock provides an estimate of how your biology is ageing.

Supplements can be useful, but they are not a substitute for a balanced diet or healthy lifestyle. Nutrient needs vary between individuals, and factors such as diet, age, lifestyle and nutrient absorption can all influence whether supplementation may be beneficial.

There are also limitations to relying solely on conventional recommended intake levels. These recommendations are generally designed to prevent deficiency and support basic health, rather than necessarily defining the levels associated with optimal long-term health and healthy ageing.

As we age, changes in digestion and nutrient absorption may also affect how efficiently the body obtains and uses certain nutrients. At the same time, modern lifestyles and dietary patterns can make it challenging to consistently obtain sufficient amounts of certain vitamins, minerals and other nutrients from food alone.

However, supplementation is not simply a matter of taking more. The form, dose, combination and individual need all matter, and taking unnecessary or excessive supplements may not provide additional benefit.

For this reason, supplementation is best considered as one part of a broader approach to healthy ageing, alongside nutrition, physical activity, sleep and other lifestyle factors.

The goal isn't simply to take more supplements — it's to understand what your body needs and make informed choices to support long-term health.

Research into ageing suggests that some aspects of ageing may be partially reversible, particularly at the cellular and molecular level. Scientists have explored approaches such as epigenetic reprogramming and the removal of senescent cells, with promising results in animal studies.

In humans, research is still at an earlier stage. Some studies have reported changes in epigenetic age, measured using epigenetic clocks, following interventions involving diet, exercise, stress management and certain compounds. These findings suggest that biological ageing may be modifiable, but they do not mean that a person's chronological age can literally be reversed.

For example, one study reported a reduction in epigenetic age following a combination of growth hormone, metformin and DHEA, while another reported changes in epigenetic age after an intensive lifestyle programme.

At OritovCare, this distinction is important: chronological age tells you how many years you have lived, while biological-age testing looks at biological markers associated with the ageing process. Changes in these markers can provide insight into how your body is ageing over time.

So, while science has not yet established a way to make an older human physically become young again, research suggests that some biological processes associated with ageing may be modifiable and, in certain measures, partially reversible.

Ageing is a complex process influenced by many factors, but there are things you can do today to support healthier ageing. The source describes two broad approaches: low-tech lifestyle interventions and high-tech biotechnology.

The lifestyle approach focuses on everyday factors such as nutrition, exercise, sleep, stress management, social connection and maintaining an active mind. The source also highlights preventive healthcare, avoiding smoking, maintaining oral health and being proactive about your own health.

Nutrition is presented as an important part of healthy ageing, with an emphasis on minimally processed foods, vegetables, legumes, mushrooms, fruits, nuts and seeds, while limiting excessive sugar, alcohol and highly processed foods.

Beyond lifestyle, emerging biotechnology is exploring ways to target biological processes associated with ageing, including mitochondrial health, cellular waste and epigenetic changes. These technologies are still being developed and are described in the source as a longer-term approach.

In simple terms, you cannot stop chronological ageing, but you can take steps that may support healthier ageing and potentially influence biological markers associated with ageing.

Ageing is not caused by a single process. Scientists describe it as the result of multiple interconnected biological changes that develop within our cells and tissues over time. These processes are commonly described as the Hallmarks of Aging.

The framework helps explain why our bodies change as we age. The original Hallmarks of Aging framework identified nine key processes, while newer research has expanded the framework to 12 interconnected hallmarks.

These include: Genomic instability, Telomere attrition, Epigenetic alterations, Loss of proteostasis, Deregulated nutrient sensing, Mitochondrial dysfunction, Cellular senescence, Stem cell exhaustion, Altered intercellular communication, Inflammaging, Microbiome dysbiosis, and Impaired autophagy.

These hallmarks are interconnected rather than isolated. Changes in one biological process can influence others, contributing to the broader ageing process. Understanding these mechanisms gives researchers a framework for studying how biological ageing occurs and how it might be measured or modified.

In simple terms: the Hallmarks of Aging provide a scientific framework for understanding the biological processes that contribute to how our bodies change as we grow older.
