How does the age test from epiAge work?

The age test from epiAge offers an accurate determination of your biological age through an innovative process.

Your biological, or so-called epigenetic age, gives insight into how your body has aged until now.

This can help you draw conclusions about your health status: If your biological age is lower than your actual age, it indicates that you are well on your way to maintaining good health in the long term – even in old age. Conversely, if your epigenetic age is higher than your chronological age, it may be a sign that it's time to adjust your lifestyle.

The test is performed by analyzing so-called methylation markers around your DNA, which only requires a small saliva sample.

With the epiAge test kit, you can easily collect this sample and send it back for laboratory analysis. You will receive the assessment and your test result within 4 weeks.

Once your epigenetic age has been determined, you can monitor the effectiveness of your health promotion measures with great accuracy by carrying out a follow-up test.

The epiAge test offers very high accuracy thanks to its advanced sequencing technology.

It is also an ideal gift for anyone who wants to take control of their own life and health.

Why should I test my biological age?

Testing your biological age can offer several key insights and benefits:

  • Personal health insight: A biological age test gives a more accurate indication of your health than your chronological age alone. It reflects how your lifestyle, environment and genetics have collectively affected your body until now.
  • Guidance for lifestyle changes: If your biological age is higher than your chronological age, it may signal the need for changes in your lifestyle. Factors such as diet, physical activity, sleep quality, as well as smoking and alcohol consumption, can all have a significant impact on your biological aging process.
  • Measurement of health-promoting measures: By knowing your biological age before and after implementing certain health-promoting measures, such as an improved diet or increased physical activity, you can measure the effect of these measures with great accuracy. This provides a unique opportunity to see direct results of lifestyle changes or supplement regimens on your biological aging process.
  • Motivation for a healthier life: Discovering that your biological age is lower than your chronological age can be a great motivation factor to continue with healthy habits. In the same way, a higher biological age can motivate positive changes.
  • Prevention and proactivity: Understanding your biological age can inspire a more proactive approach to your health, focusing on prevention rather than treatment. This can lead to early detection and management of potential health problems before they develop.

Testing your biological age can therefore be a powerful tool to guide and inform your health and lifestyle decisions, and help you set targeted, personal goals to improve your long-term health and well-being.
