Biological Age vs Chronological Age: How Much Control Do We Really Have?

We understand age as the number of years that have passed, moving in one direction only. It’s fixed, measurable and, in practical terms, outside our control. However, there has been much attention over recent years around another way to measure and think about ageing. You may be familiar with the term biological age. Rather than simply reflecting years lived, it reflects how the body is functioning, and is shaped by underlying processes such as metabolic health, inflammation, cellular repair and the efficiency with which energy is produced and used. Many of these processes are described within what is often referred to as the Hallmarks of Aging.

These are the systems that influence how we feel day to day, including energy, resilience and the ability to recover.

Why people age differently

This helps explain something most people recognise. Two people of the same age can feel (and look) very different. One may feel well, active and mentally sharp, while the other feels persistently tired, slower to recover and less resilient to stress. Chronological age doesn’t fully account for that difference, but biological age begins to. The question, and the real interest here, is how much influence we have over this.

The role of genetics

For a long time, ageing was thought to be largely predetermined. Genetics clearly play a role, particularly in shaping susceptibility to certain conditions and, at the extremes, longevity itself. But a growing body of research now suggests that for most people, genetics are only part of the picture. Large population studies, including data from the UK Biobank, suggest that lifestyle and environmental factors may have a greater influence on health outcomes than genetic predisposition for most people.

Lifestyle and environmental influence

Lifestyle and environmental factors appear to have a greater influence on how the body functions over time. The way we eat, move, sleep and recover all interact with the biological systems that underpin ageing. These patterns, repeated consistently over years, influence processes such as inflammation, metabolic regulation and cellular maintenance. Over time, this is what shapes how we feel, not just how old we are.

A shift in perspective

This moves the conversation away from age as something that simply happens, and towards something that responds to how the body is supported. It doesn’t suggest that ageing can be stopped or avoided, but it does suggest that we have more control over the process than we may have thought.

Can biological age change?

There is also increasing interest in whether biological age can change over shorter periods of time. Some studies have explored the impact of combined dietary and lifestyle interventions on markers associated with ageing, including DNA methylation patterns. Some intervention studies have reported measurable changes in these markers over relatively short periods, although this remains an emerging area of research. What is clear, and consistent across the literature, is that the foundations matter. Diet, physical activity, sleep and the management of chronic stress all influence the systems that underpin energy, recovery and resilience. These are not short-term interventions, but patterns that accumulate over time.

Where targeted support fits

Within that context, there can also be a role for more targeted support. Nutritional status, absorption and individual requirements are not always optimal, and this can influence how effectively these systems function. Where appropriate, supplementation can sit alongside the fundamentals, not as a replacement, but as an additional layer of support.

Where CAMINO sits

This is where CAMINO sits. The focus is not on altering age itself, but on supporting the underlying biology that contributes to how the body functions over time. By supporting processes related to energy production, recovery and resilience, with clinically studied active ingredients, the aim is to influence how people feel day to day, and how those patterns are sustained.
