How does the test work?
  1. Zest will deliver a test kit to your door. We provide instructions on how to take a finger-prick blood sample and send this back to our lab in the pre-paid envelope. 
  2. Download the Zest app and create your account.
  3. Test cognitive and functional performance in app. 
  4. Our lab will send your test results to your app, showing you the blood biomarkers that are impacting your rate of aging and where to improve.
  5. Zest will incorporate this digital and functional data, alongside your blood test data to give you a measure of your Functional Age, accurate to within 2 years. .
How will my results help me?
  1. Your Functional Age score will establish how well each of your body’s systems (cardiac, joints, kidney, liver and brain) are aging.
  2. Once we know this, the Zest App will provide tailored recommendations for you to improve this score and slow your rate of aging. 
  3. Recommendations will include, exercise targets, brain exercises, sleep improvements, supplement protocols and more to unlock a healthier lifestyle.
How often should I test?
  1. The Zest Functional Age score can be improved within three months, due to the incorporation of our functional and digital biomarkers. 
  2. No other test on the market is this sensitive. 
  3. We recommend testing, implementing lifestyle changes for 6 months and then testing again to see the improvement.
What countries do you ship to?

The Zest app is downloadable from all countries. Currently our blood tests and supplement packs are currently only available in the USA and Canada.

Zest Longevity Panel
Biomarkers

This test is comprised of the 9 biomarkers which have been shown repeatedly in the literature to be the most closely linked to health span and lifespan.

Using the results of this blood test alone, we can predict age to within 5 years of accuracy. When you combine these blood test results with digital and functional biomarkers through our app, the accuracy improves to within 1 year of a user’s chronological age, making it one of the most accurate biological clocks on the market. The field of longevity is rapidly evolving, and we are committed to adapting our panel based on new developments in the research (hence our recent addition of ApoB to the panel).

Biomarkers included in panel:
LDL
Blood
Chemical symbol for LDL's

LDL (low-density lipoprotein) cholesterol is another type ofblood lipid. High amounts of LDL cholesterol can significantly increase your risk of developing cardiovascular disease, dementia, and other chronic conditions.

CRP
Digital
Chemical symbol for LDL's

hsCRP is a high-sensitivity test for C-reactive protein (CRP), a protein that is elevated in states of inflammation. Increased levels of CRP correlate with an increased risk of cardiovascular disease, diabetes, kidney disease, and dementia.

Albumin
Functional
Albumin chemical symbol in green

Albumin is a blood protein that plays a crucial role transporting compounds around our body and helping to control blood pressure and pH. Albumin levels show how well your liver and kidneys are functioning. Low levels correlate with age and an increased risk of all-cause mortality.

ApoB
Blood
Chemical symbol for APOB in green and yellow

Apolipoprotein B-100 is a protein that helps carry fat and cholesterol through your body. It is a new and improved way of measuring cardiovascular risk and is thought to be a better predictor than LDL cholesterol levels, particularly for younger people. It is a newly popular biomarker which we have recently added to our panel as we strive to remain at the leading edge of longevity research.

Triglycerides
Blood
Chemical symbol for triglycerides

Triglycerides are a type of lipid found in the bloodstream. They are used as a source of energy, but high levels are harmful for your health. High triglyceride levels significantly increases risk of developing cardiovascular disease and diabetes, which are both linked to shorter lifespan and healthspan.

HDL
Blood
chemical symbol for HDL's

Cholesterol is a blood lipid (or fat) that is crucial for energyproduction and transport. HDL (high-density lipoprotein) cholesterol is a form that is generally beneficial to your health and longevity. High HDL levels will reduce your chances of developing chronic diseases including cancer, diabetes, cardiovascular disease, and dementia.

HbA1c
Blood
Chemical symbol for HbA!c

HbA1c is a longer term blood glucose level. It measures the amount of glucose bound to red blood cells in your circulation. Since the lifespan of a red blood cell is around 3 months, it gives us a snapshot of what your blood glucose levels have been like across the past 3 months. Higher values of HbA1c increase the risk of diabetes, cardiovascular disease and death of any cause.

Fasting glucose level
Blood
Chemical symbol for glucose

Fasting blood glucose is a measure of how much glucose - the main compound the body uses for energy - is present in your blood when you have been fasting for at least 8 hours. High blood glucose increases your risk of diabetes, cardiovascular disease, cognitive decline, and other age-related diseases.

Oestradiol
(Female only)
Blood
Chemical symbol for oestradiol

Oestradiol is the primary form of the major female sex hormone oestrogen. Oestradiol levels begin to decline around the onset menopause, which can result in bone weakness and decline in reproductive health. Low oestradiol levels can reduce your bone density and cause unpleasant symptoms such as hot flushes and mood swings, as well as increase the risk of cognitive dysfunction.

DHEAS
(Female only)
Blood
Chemical symbol for DHEAS

DHEAS (dehydroepiandrosterone sulfate) is the compound that the body uses to make testosterone and oestradiol, making it crucial for sexual function as well as bone, muscle and reproductive health. DHEAS levels naturally decrease with age which can cause fatigue, mood swings, and sexual or reproductive dysfunction. Low levels of DHEAS increase your risk of osteoporosis, stroke, cardiovascular disease, and cognitive dysfunction.

Testosterone
(Male only)
Blood
Chemical symbol for testosterone

Free testosterone is a measure of how much testosterone is circulating in the blood and able to act on your organs. Free testosterone levels naturally decrease with age, causing bone and muscle weakness, low libido, mood disorders, and increased risk of metabolic syndrome. Maintaining high testosterone levels is a powerful way to combat aging and lengthen your healthspan.

SHBG
(Male only)
Blood
Chemical Symbol for SHBG

SHBG (sex hormone-binding globulin) is a protein that binds to testosterone and other sex hormones in the blood, thereby helping to regulate their levels. In males, SHBG levels naturally rise with age, meaning less available testosterone and other sex hormones, causing bone and muscle weakness, low libido, and mood disorders. High SHBG levels have also been linked to an increased risk of Alzheimer’s disease.

Why combine NMN & TMG

NMN has been proven to provide anti-aging benefits by enhancing the function of common proteins (Sirtuins and PARPS), through NAD+ production.

NMN is clinically proven to improve: 

  • Energy production in mitochondria
  • Oxidative stress
  • DNA damage
  • Cognitive impairement
  • Inflammatory conditions


TMG has been approved by the FDA to lower homocysteine in our blood plasma which can help fight off cardiovascular issues.

NMN & TMG work together as NMN-induced NAD+ production requires the use of the methylation process, supported by TMG. TMG is known as a  methyl group donor. NMN and TMG together offer one of the best ways to activate and support the healthy function of our internal anti-aging processes.

Essentials blend bottle on a blue background

What is NMN?

NMN (Nicotinamide mononucleotide) stands as the hero of longevity supplements.  Derived from niacin (Vitamin B3),  NMN helps to boost NAD+ in your cells. This can lead to a boost in your cellular energy levels,  improved cognitive health for a sharper mind, improved cardiovascular health through better vascular function, and an improved metabolism.

Zest’s Pure NMN Capsules use Enteric Coated Acid-Resistant non-GMO capsules that are designed to resist stomach acids and absorb in the small intestine, improving the bioavailability of the NMN by 30% compared to regular capsules.

What are the effects?

NMN and in turn NAD+  affect energy levels, sleep quality, mental focus, fatigue levels and metabolism, to slow your rate of aging.

Essentials Blend bottle on a yellow and white background

What is TMG?

TMG, or Trimethylglycine, is a compound derived from beets and other plants. Also known as betaine, TMG plays a role in supporting methylation processes in the body. It is often included in supplements for its potential benefits in promoting liver health, cardiovascular function, and overall cellular methylation.

Trimethylglycine operates in the body as a methyl donor for various crucial biological processes. By donating methyl groups, TMG supplements aids the conversion of homocysteine to methionine, contributing to a balanced methylation cycle.  It also ensures supplements the use up methyl groups (such as NMN) can work effectively.

What are the effects?

TMG improves the efficiency of NMN supplements, and acts to improve mood, detoxification in the liver, reduce joint inflammation and promote muscle development.

Why did we build Functional Age?

Many tests take a single proxy for biological age (Inflammation age, DNA methylation etc.) However, these tests were not designed to give insight into an individuals personal longevity, but for research purposes, predominantly in animal models.

Imagine a scenario where an individual in their 60’s receives an age score in their 20’s. The data is not actionable nor does it provide insight on how to improve your healthy lifespan.

Epigenetic clocks can’t actually tell you much about your own health. That’s because they were designed to assess large groups of people, not individuals. Consequently, their results can be unreliable. (NY Times 2024.)

To tackle this problem Zest has created the only multifaceted age testing system, from the ground up, Functional Age.  We benchmark the biomarkers linked to aging and pull data from your blood, wearable device, and functional performance tests. Then provide analysis that is actionable and relevant to the individual taking the test, not the mouse or yeast trial that other common tests were developed for.

If you have excellent blood biomarkers, but warning signs present in your cognitive performance, Zest will detect it, rather than telling you that you are fit to live to 120. Giving you the necessary information to optimize this area and create a truly personalized action plan for your aging journey.

  • Your chosen longevity supplement stack, delivered monthly.
  • Zest longevity blood panel delivered every 3 months. This is an at-home finger-prick blood test consisting of the 9 blood biomarkers most closely linked to healthspan and lifespan.
  • Access to the Zest app.
  • Zest biological age calculation (coming soon).

The supplement subscription only includes supplements and app access, no blood tests. Without the blood biomarkers, we are unable to calculate biological age.

Mainstream supplements are typically designed to augment ingredients which you could regularly find in your diet to help you meet your daily recommendations. Longevity molecules are different because:

1) you don’t find any of these ingredients in your regular diet and
2) there are no established daily recommendations of these ingredients.

These ingredients have come out of recent cutting-edge research on how to biologically slow the aging process. There aren’t any government guidelines recommending certain levels of these ingredients to promote health, since they are so new and they target the aging process as a whole rather than focusing on a specific disease. Our ingredients cannot be found in most supermarkets or drug stores.

  • At 7.2 g grams per dose, we have the highest amount of pure active ingredients of any other longevity company on the market, so you’re actually getting therapeutic doses that make a difference.
  • We have the purest and highest quality ingredients, and provide purity reports and 3rd party Lab Testing as well as sourcing information for all ingredients.
  • We don’t mess around with vitamin gummies, green juice blends, or other influencer fads which aren’t backed by science. We only supply the real deal, high quality and therapeutic doses backed by 100+ clinical trials.
  • We separate our supplement packs into hydrophobic and hydrophilic to optimize absorption and reduce gastrointestinal upset. This means the ingredients are actually getting into your cells, unlike for many multivitamin companies which just cause you to make expensive pee.
  • We have expertly curated our supplement stacks to target all 12 root causes of aging, making you biologically younger on the inside.

Zest’s functional age calculation is the most accurate and holistic biological age score on the market, and the only one which takes into account your cognitive function as well as your physical health. We use a combination of blood biomarkers, digital biomarkers and functional biomarkers (including memory tests) which we run through our machine learning algorithm to give you the most accurate and research-backed biological age measurement yet. Our blood test includes markers for your cholesterol levels, hormone levels, liver enzymes, and other tests grounded in 100+ years of research (the OG science, not just the latest fads). We then add this to our digital biomarkers such as resting heart rate, sleep, mood, VO2 max score, and other metrics which give real insight into your day to day functionality. Finally we include grip strength and some cognitive tests as part of our “functional biomarkers” and together this makes up the data that goes into our functional age algorithm to give you a result for your biological age.

At Zest, we want to make longevity easy. We have a team of medical doctors and longevity scientists constantly examining the latest literature to determine which ingredients should go into the ultimate life-extending supplement stack. We continuously update these packs as new research emerges to ensure the ingredients you’re taking are at the forefront of medical and scientific research. No need to spend hours doing your own research, we are the experts and we have you covered! Just subscribe to the membership and Zest takes care of the rest.
