Getting older is guaranteed. How you age is not.

Ageing is one of the few things in life that’s truly guaranteed. But the way you age (how your body functions, your risk of disease, and the quality of your years) is far more flexible than most people realise.

That’s where the concept of biological age comes in. Unlike your calendar age, which simply tracks how many birthdays you’ve had, your biological age measures how well (or poorly) your body is ageing on the inside. And it’s now a key part of Everlab’s diagnostic reporting in the Everlab App.

What is biological age?

Biological age is an estimate of the “wear and tear” happening in your body at a cellular level. While you might be 55 on paper, your cells could be functioning more like those of a 45-year-old — or, if risk factors are stacking up, a 65-year-old.

It’s not about appearances or vanity. It’s about what’s happening beneath the surface: how resilient your cells are, how your organs are coping, and how much hidden risk may be building.

In other words, biological age gives you a deeper answer to the question: “How am I really ageing?”

The beauty vs. biology trap.

Conversations about ageing often get stuck on the outside — wrinkles, skin, hair, appearance. But while there’s nothing wrong with caring about how you look, biological age is about something much more important: your long-term health.

When you know your bio age, you gain insight into your body’s resilience. A younger biological age usually means your systems are functioning better and your risks of chronic disease are lower.

Why biological age matters for prevention

One of the most powerful things about biological age is its link to chronic disease risk. The same biomarkers that are used to calculate bio age are also relevant to conditions like:

• Heart disease
• Type 2 diabetes
• Cancer
• Dementia
• Osteoporosis

That means your bio age isn’t just an interesting number. It’s a signal of what’s happening inside your body — and whether you might be heading toward disease or staying on a healthy trajectory.

How we calculate biological age at Everlab.

No biological age calculation is perfect. But the science is strong enough to give meaningful insights when applied carefully. At Everlab, we calculate biological age using nine clinically-validated biomarkers that capture key aspects of your health:

• Albumin
• Creatinine
• Glucose
• C-reactive protein (CRP)
• Lymphocytes
• Mean cell volume
• Red cell distribution width
• Alkaline phosphatase
• White blood cells

These are combined to create a single estimate of your biological age. But importantly, this is only the beginning. In total, our diagnostic process measures over 100 biomarkers across your blood, scans, and physical assessments. Biological age is one lens in a much bigger picture — one that helps your doctor build a prevention plan designed specifically for you.

Can you change your biological age?

The most empowering part of biological age is that, unlike your calendar age, it can be slowed — and even reversed.

Research shows that simple, consistent lifestyle changes can reduce biological age while also lowering the risk of chronic disease. Some of the most effective levers include:

• Fibre-rich foods → support gut health and metabolic function
• Minimising ultra-processed foods → reduce chronic disease risk
• Lean protein → maintain muscle and metabolism
• 30 minutes of cardio daily → aim for Zone 2 for endurance and heart health
• Resistance training twice per week → preserve muscle mass and bone strength
• Reducing alcohol intake → support healthier ageing overall

These aren’t fads or extremes. They’re sustainable changes with long-lasting impact.

Why we added bio age to the Everlab App.

At Everlab, our mission is to make prevention visible, measurable, and actionable. Biological age is a powerful way to help you see the bigger story of your health — and track whether your actions are making a difference.

From the moment you log into the Everlab App, you’ll see your biological age on your dashboard alongside other key metrics. Over time, you’ll be able to see how it shifts as you make changes and follow your personalised prevention plan.

This isn’t about chasing youth or aesthetics. It’s about giving you confidence that your efforts are working, and reassurance that you’re staying one step ahead of disease.

The real win: feeling the difference.

Your biological age will shift throughout your life — sometimes up, sometimes down. But the real win isn’t just a lower number on a screen. It’s the energy, clarity, and resilience you feel day to day.

By measuring and managing your biological age alongside more than 100 other biomarkers, we’re able to give you something far more valuable than reassurance: a plan for a more healthy years.

Because getting older is guaranteed. But how you age is up to you.
