Traditional epigenetic clocks and DNA-methylation based biological age calculations

  • Developed for research purposes, not designed for consumer use [1]
  • Do not change even when users follow protocols known to extend lifespan such as exercise and calorie restriction [2, 3]
  • Poorly correlated with lived experience. Many studies have shown that lower epigenetic age is NOT linked to improvements in cardiorespiratory fitness, walking speed, muscle strength and various other functional measures [4 5 6].
  • Does not offer granularity as to which aspects of your health are bringing down your age and how to improve them, since it is just one overall number.
OUR MISSION

Help everyone live healthier for longer

Over the past century, we've nearly doubled our lifespan, yet the quality of life hasn't kept pace. That's where Zest comes in. Welcome to a future where we increase both lifespan and healthspan

Get Started

Zest Functional Age calculation:

  • Developed alongside leading researchers from the University of Cambridge specifically for use in consumer longevity science, not just in theoretical research.
  • Will change on a short-medium term basis (within 3 months) if you implement a health-optimizing routine.
  • Inherently linked to your physical and cognitive functionality, so as your fitness and performance improves, you will see that reflected in your Functional Age.
  • Offers a breakdown of how you scored in physical, cognitive and functional biomarkers to help you develop a targeted longevity protocol to improve your Functional Age.

What About Supplements?

ZEST PROVIDES YOU WITH THE TOOLS TO ORDER TRUSTED SUPPLEMENTS AND MONITOR YOUR PROGRESS

Research is still ongoing on which supplements are clinically proven to extend healthspan, and so we do not recommend specific supplements directly.

We do however recognize that everyone's threshold for evidence is different, and many people still wish to take novel longevity therapeutics. For these enthusiastic biohackers, we provide the technology to track supplement usage, log dosage and side effects, and monitor impact of supplements on various digital and blood biomarkers....

The 3 Pillars of Functional Age

Icon

Digital Biomarkers

  • Over 15 different digital biomarkers collected from your wearable device
  • These include markers such as VO2 max, resting and max heart rate, sleep data, mood, energy levels, circadian rhythm alignment and more
  • All digital biomarkers have been specifically selected due to their strong correlation with healthspan and lifespan
Icon

Functional Biomarkers

  • We collect these functional biomarkers once every 3 months when a user is prompted to re-test their functional age.
  • Collection is fully integrated in-app, in the form of clinically validated memory games such as the digit span memory test and sequence memory test.
  • These are unique to Zest and include markers such as mood, grip strength, and cognitive function
Icon

Blood Biomarkers

  • Our team of doctors and scientists developed our bespoke Zest Longevtiy Panel which is a simple finger-prick home blood test
  • This is a panel of 9 biomarkers proven in clinical trials to be linked to healthspan and lifespan
  • We are constantly updating this panel to ensure it is in line with the latest research, (for example we just added ApoB based on new evidence).

For these enthusiastic biohackers, we provide the technology to track supplement usage, log dosage and side effects, and monitor impact of supplements on various digital and blood biomarkers.

We also provide access to trusted high quality agents for those wishing to take supplements, however it is by no means a requirement of the Zest platform.

We know tracking progress can be hard.

Zest makes it easy

One of the biggest pain points of our clients is that it's difficult to know if what they're doing is making any difference. They often spend hundreds of dollars on gym memberships, supplements, and lifestyle interventions but have no way of measuring whether any of it is working. This makes it difficult to stay motivated or know what is a valuable spend and what is a waste of money.

At Zest, we have implemented accurate progress tracking of digital and blood biomarkers, and use machine learning to help pinpoint which elements of your longevity protocol are most effective and how you can maximise your performance while minimising wasted time and money.
