Best Biological Age Test in New Zealand

At For Youth, you can order one of the most accurate biological age tests in New Zealand — The Clock. Powered by DNA methylation analysis, it measures how fast your body is truly ageing on a cellular level, not just how many candles are on your cake. As we age, our biological systems slow down and become more vulnerable to stress, disease, and inflammation. By understanding your biological age, you gain insight into how your lifestyle is affecting your long-term health. The Clock is a simple, saliva-based test designed to give you clear, science-backed results — so you can take control of your ageing process and make changes that matter.

Frequently Asked Questions

What is a biological age test?

A biological age test measures how fast your body is ageing on a cellular level, which can differ from your actual (chronological) age. It’s a more accurate indicator of your overall health and long-term resilience.

How does a DNA methylation test work?

A DNA methylation test analyses patterns of methyl groups attached to your DNA — changes that strongly correlate with ageing. By examining these patterns, it calculates your biological age with high accuracy.

What are the benefits of taking a biological age test?

It helps you track how lifestyle changes, supplements, diet or exercise are impacting your ageing. It can also motivate healthier habits and give early insights into your long-term health trajectory.

Is a saliva-based biological age test accurate?

Yes — especially when based on DNA methylation. Saliva-based tests like The Clock use well-established methods and deliver results comparable to blood-based epigenetic tests.

Why choose The Clock by For Youth?

Many biological age tests bundle in extra health scores or upsell coaching — but For Youth’s The Clock focuses on what matters: your biological age. It's saliva-based, private, and powered by gold-standard DNA methylation science — giving you accurate, actionable results with no unnecessary add-ons.
