Understanding your biological age can be a game-changer for assessing your overall health and longevity. Unlike chronological age, which is the number of years since birth, biological age reflects your body’s physiological and functional condition. This article explores the science of biological age, its relevance, and practical ways to calculate it using innovative tools and apps.
What is your biological age?
Biological age indicates how well your body is aging compared to the average person of your chronological age. While your chronological age progresses steadily, your biological age may advance faster or slower, depending on factors like genetics, lifestyle, and environmental exposure.
For instance
A 40-year-old person with excellent health markers might have a biological age of 30, signifying slower aging. Conversely, someone with poor health habits could have a biological age of 50, indicating accelerated aging.
Another example is Bryan Johnson, who has dedicated his life to longevity and takes an extremely structured approach to his routine. He follows a strict protocol that includes intermittent fasting, optimized sleep, intense training, and a whole range of supplements. He has reversed his biological age by 5.1 years, and his heart now functions like that of an average 37-year-old. Read the full blog here: Bryan Johnson Blueprint protocol
Chronological age vs. biological age
Chronological age: Simply put, this is the age in years from your birth date. It’s a straightforward measurement of time.
Biological age: In contrast, this is a reflection of your body’s health and vitality. It encompasses various markers, including cellular health, organ function, and metabolic performance.
Bio age and its implications
Biological age – or bio age – is more than just a number. It reflects how well your body is functioning compared to your actual age. It offers insights into:
Cellular health: The state of your DNA and cell function.
Lifestyle impact: Effects of diet, exercise, and habits.
Disease risk: A higher biological age might correlate with greater susceptibility to chronic illnesses.
How do you calculate your biological age?
Several methods can estimate your biological age. Some are based on advanced scientific models, while others use accessible tools like apps.
1. Using a biological age test
One of the most accurate methods is taking a professional biological age test. These tests measure biomarkers like DNA methylation, inflammation levels, and metabolic rate. For example, the Muhdo Biological Age Test offers a comprehensive analysis to determine your biological age.
2. Online questionnaires
Some websites offer simple questionnaires to estimate your biological age. These tools ask about your habits, diet, activity level, and other factors. While these assessments are quick and easy to use, they lack the precision of biomarker-based tests and should be viewed as general estimates rather than scientific evaluations.
If you’re curious about your biological age, there are several free biological age calculators available online. These tools use basic inputs like your chronological age, activity level, diet, sleep, and lifestyle habits to estimate how old your body is functioning biologically.
Here are some popular biological age calculator tools:
You can find more by searching “free biological age calculator” – most only require a quick questionnaire and provide instant feedback.
3. Purovitalis Aura App
The Purovitalis AURA app gives you a quick, science-backed health check using just your smartphone. With a short face video, voice recording, and selfie, the app analyzes over 20 biomarkers linked to your heart, brain, lungs, metabolism, and skin.
It uses clinically validated AI to detect early signs of issues like high stress, poor recovery, or cardiovascular strain – all in under 2 minutes. Your data stays private: it’s encrypted, face videos aren’t stored, and everything is deleted if you cancel.
What can AURA detect?
| Area | Insight |
|---|---|
| Heart & lungs | Heart rate, blood pressure, oxygen, stress |
| Brain & mood | Cognitive sharpness, depression signs |
| Metabolism | Inflammation, fatigue indicators |
| Skin health | Hydration, tone, signs of aging |
4. Metabolic age calculation
For a deeper dive into your biological metrics, you can combine the Aura app with wearable devices like the Apple Watch or other fitness monitors. These devices track data like heart rate variability, VO2 max, and calorie expenditure, which are key components in calculating your metabolic age. This integrated approach gives you a more dynamic and real-time understanding of your body’s functional age.
By combining apps, wearables, and tests, you can gain a nuanced understanding of your biological age. Whether you’re exploring quick questionnaires or leveraging advanced tools, the insights you gather can guide better health decisions.
Why biological age matters
Your biological age isn’t just a number; it’s a reflection of your health and longevity potential. Tracking it helps you:
- Identify areas for improvement.
- Adopt healthier habits.
- Monitor the effectiveness of lifestyle changes.
For instance, incorporating longevity hacks like intermittent fasting and regular exercise can significantly reduce your biological age.
Factors affecting your biological age
Biological age is influenced by several key factors, including:
- Lifestyle choices: Smoking, drinking, and poor diet accelerate aging.
- Stress levels: Chronic stress increases cortisol, leading to faster aging.
- Genetics: Inherited traits also play a role.
- Environmental exposure: Pollution and toxins can damage cells and DNA.

What is metabolic age?
Metabolic age evaluates how efficiently your body operates compared to others in your age group. A lower metabolic age often indicates better health and fitness. Improving metabolic health through regular exercise and a balanced diet can reduce your overall biological age.
How to improve biological age?
Reducing your biological age requires a comprehensive approach. Here are some practical strategies:
| Area | Why it matters |
|---|---|
| Prioritize nutrition | Nutrient-dense foods with antioxidants and healthy fats reduce inflammation and oxidative stress. Avoid processed foods and excess sugar. |
| Exercise regularly | Boosts heart health, muscle strength, and metabolism. Combine aerobic and strength training. |
| Optimize sleep | 7–9 hours of quality sleep helps the body repair and slows aging. Poor sleep speeds up decline. |
| Manage stress | Techniques like meditation and deep breathing reduce cortisol and support hormonal balance. |
| Take supplements | Supplements like NMN, spermidine, magnesium, D3 and omega-3 can support energy, cell repair, and longevity goals – especially if diet alone isn’t enough. |
