Learning how to improve your biological age is one of the most important steps you can take for your long-term health. The good news is that, with the right approach, it is possible to make meaningful, measurable improvements that support how your body functions and feels over time.
What Is Biological Age and Why Does It Matter?
Biological age is a measure of how old your body is at a cellular level, rather than how many years you have been alive. Two people born in the same year can have biological ages that differ by a decade or more, depending on their lifestyle, genetics, and health history.
Understanding your biological age gives you actionable data. It tells you whether your current habits are accelerating or slowing the ageing process, and it highlights specific areas where intervention can have the greatest impact.
How a Biological Age Test Can Track Your Progress
If you are serious about improving your biological age, testing is not optional. Without a baseline measurement, you have no way of knowing whether your interventions are working. A biological age test gives you the data you need to make informed decisions about your health.
At Regenesis, we offer a range of biological age testing packages in the UK designed to suit different budgets and health goals. Our tests are built around the GlycanAge test, a scientifically validated analysis that measures IgG glycans in your blood to provide an accurate insight into your immune system’s age.
The biological age test is particularly valuable because it reflects the cumulative impact of your lifestyle choices on your immune system. Unlike many other biological age markers, glycan patterns are highly responsive to positive lifestyle changes, making retesting a reliable way to confirm your progress.
Understanding the Cost of Biological Age Tests in the UK
One of the most common questions we receive is about the cost of a biological age test. At Regenesis, we offer four packages to make testing accessible at a range of price points.
-
- Basic Package (£299): Ideal for a straightforward biological age measurement.
- Standard Package (£398): Includes additional health markers alongside the core GlycanAge test.
- Premium Package (£897): A comprehensive assessment with detailed reporting and consultation.
- Ultra Package (£1,146): Our most thorough biological age testing option, covering a full spectrum of biomarkers.
The price for a biological age test reflects the depth of analysis included. We recommend starting with at least the Standard package to get a meaningful overview of your biological age and the factors driving it.
Prices are subject to change. Please contact us for the most up-to-date information.
How to Improve Biological Age Through Diet and Nutrition
Nutrition is one of the most effective ways to support improvements in biological age. A diet rich in anti-inflammatory foods, including leafy greens, oily fish, berries, and olive oil, directly supports cellular repair and reduces the oxidative stress that accelerates ageing.
Reducing ultra-processed foods, refined sugars, and excess alcohol has a measurable impact on inflammatory markers, which are closely tied to how quickly your biological clock ticks. Intermittent fasting and caloric restriction have also shown promising results in reducing biological age in multiple clinical studies.
Exercise as a Way to Improve Biological Age
Regular physical activity is arguably the single most effective lifestyle intervention for reducing biological age. Both aerobic exercise and resistance training have been shown to lengthen telomeres, reduce inflammatory cytokines, and improve mitochondrial function, all of which are key markers of cellular health.
We recommend aiming for a combination of moderate aerobic activity (such as brisk walking, swimming, or cycling) and strength training at least three to four times per week. Even modest increases in physical activity produce measurable improvements in biological age markers within eight to twelve weeks.
Did You Know?
Research found that a combination of diet and exercise reduced biological age by 2.2 years in older adults with obesity, demonstrating that meaningful, measurable change is achievable with the right approach.
Advanced Therapies to Help Improve Biological Age
Beyond lifestyle changes, regenerative therapies can support the process of improving biological age at a deeper cellular level. Mesenchymal stem cell therapy, for example, may help reduce inflammation and support tissue repair by introducing regenerative cells into targeted areas.
We also offer a range of mechanotherapy treatments, including photobiomodulation (red light therapy), PEMF therapy, and shockwave therapy. These energy-based treatments are designed to stimulate cellular activity, reduce inflammation, and support recovery, all of which may contribute to improvements in biological age over time.
Your Next Steps to Improving Biological Age
Knowing how to improve your biological age is the first step, but acting on that knowledge is what produces real results. A combination of targeted nutrition, regular exercise, and evidence-based therapies gives you the best chance of improving your biological age.
The GlycanAge test and our broader range of biological age testing packages give you the precise data you need to track your progress and stay accountable. Whether you are exploring a biological age test in the UK for the first time or looking to deepen an existing longevity protocol, Regenesis is here to support you at every step.

Frequently Asked Questions
Can you actually reverse biological age, or just slow it down?
It is possible to reduce biological age markers, not just slow their progression, with the right combination of lifestyle changes and clinical support. Targeted lifestyle changes and clinical interventions can lower biological age markers by two years or more, meaning your cells are measurably functioning younger than before.
How long does it take to improve biological age?
Most people begin to see measurable improvements in biological age markers within three to six months of consistent lifestyle changes. Retesting with the GlycanAge test at the six-month mark is a reliable way to confirm progress.
What is the GlycanAge test, and how does it work?
This test analyses IgG glycan patterns in a blood sample to measure how old your immune system is at a biological level. It is one of the most responsive and scientifically validated biological age markers currently available.
How much does a biological age test cost in the UK?
The biological age test at Regenesis starts at £299 for the Basic package and up to £1,146 for the comprehensive Ultra package. The cost reflects the depth of biomarker analysis and consultation included in each tier.
Is the biological age test available without a referral?
Yes, you do not need a GP referral to access a biological age test through Regenesis. You can book directly through our website and receive your results with a full clinical consultation included in most packages.
What lifestyle changes have the biggest impact on biological age?
The most impactful changes are a whole-food, anti-inflammatory diet combined with regular aerobic and resistance exercise. Reducing alcohol, improving sleep quality, and managing chronic stress also produce significant results and are some of the first steps when learning how to improve biological age over time.
Are stem cell therapies worth considering for improving biological age today?
For people with joint degeneration or significant inflammation, mesenchymal stem cell therapy offers a clinically supported option that may help address aspects of biological ageing at a cellular level. It works best as part of a broader programme that includes lifestyle optimisation and regular biological age testing.
