When you’ve heard of billionaire Bryan Johnson, you’ve seemingly encountered the phrase “bio age testing.”
Johnson, the topic of the Netflix documentary Don’t Die, says he’s on a quest to attain the bottom attainable “organic age” (often known as bio age).
He reportedly spends hundreds of thousands annually on anti-aging remedies—dozens of each day dietary supplements, weekly acid peels for his pores and skin, injections to spice up collagen manufacturing, hyperbaric oxygen remedy, and plasma infusions extracted from his 17-year-old son’s physique.
To find out what’s working, Johnson has undergone quite a few assessments to evaluate his bio age. Johnson says these assessments present his age is now 5.1 years youthful than when he launched into his anti-aging quest.
Apparently, he’s ageing in reverse.
Granted, not everybody’s shopping for it. A New York Occasions exposé, for instance, claims Johnson’s organic age, in actuality, has elevated by 10 years.1
Nonetheless, Johnson’s “don’t die” campaign is gaining traction.
Bio age assessments are a frequent matter on standard podcasts by Peter Attia, Joe Rogan, and Andrew Huberman. Google “bio age testing” and also you’ll see dozens of adverts for mail-order blood or urine testing kits that declare to disclose your organic age, tempo of ageing, and extra. With costs tumbling into affordability, it’s pure to surprise…
Do you have to or your shopper join bio age testing?
If that’s the case, which take a look at is greatest? Simply as importantly, what must you do with the knowledge?
On this story, you’ll study:
What’s your bio age?
Your organic age (bio age) refers to how your cells operate. It’s not essentially the identical as your chronological age, which refers back to the variety of candles in your birthday cake.
For instance, let’s say Chang, a 50-year-old man, works at a desk, spends his free time in entrance of the TV, lives in probably the most polluted metropolis on this planet, eats a sweet bar for lunch, and smokes. However, Jabari, a unique 50-year-old man, hits the health club a number of occasions every week, lives within the mountains, doesn’t smoke, relishes his 5 servings of veggies a day, meditates, and spends most evenings in his backyard.
Genetics apart, you’d be sensible to wager that Jabari’s bio age is youthful than Chang’s.
How do these assessments measure bio age?
Bio age testing kits measure a number of organic markers of ageing, often known as biomarkers.
For instance, some assessments give attention to the scale of your telomeres, the protecting caps on the ends of chromosomes. Others measure DNA methylation, a physiological course of that chemically alters DNA.
As soon as an organization isolates and measures these markers out of your blood or urine, it plugs the bio information right into a formulation that calculates your bio age.
Nevertheless, for those who see a health care provider with any regularity, you’re seemingly already monitoring some biomarkers of ageing. For instance, biomarkers resembling blood stress, levels of cholesterol, and blood glucose will help predict your threat of future heart problems, a number one reason behind untimely demise.
What’s the purpose of biomarker testing?
Biomarker testing will help you monitor your wellness proactively quite than ready for illness signs to seem.
For some, it additionally serves as a motivator. When you study you will have the bones of somebody 20 years older, this will provide the nudge it is advisable begin energy coaching constantly.
As well as, biomarkers present goal information, permitting you to trace and consider numerous health-related actions quantitatively. By monitoring your blood stress, you may study that constant train helps, however your late-afternoon vitality drink does the alternative.
5 FREE biomarker assessments
You don’t must be a billionaire (or perhaps a millionaire) to trace biomarkers of ageing.
On this part, we’ll cowl a number of massively underappreciated, scientifically validated assessments you should utilize to achieve perception into your bio age—for FREE.
Earlier than scientists developed high-tech blood-based bio age assessments, researchers used these free assessments to calculate the tempo of ageing within the folks they studied.
FREE biomarker take a look at #1: Get off the ground
People who find themselves fitter and stronger are inclined to dwell longer.2
That’s as a result of muscle groups do extra than simply transfer us round. In addition they secrete anti-inflammatory substances, assist to control blood sugar, gradual mobile ageing, defend the liner of the arteries, and extra. All this helps cut back the danger of age-related illnesses, resembling kind 2 diabetes, hypertension, and coronary heart illness, a phenomenon we discover in our article, The New Science of Muscle.
Associated to energy, your skill to stability can also be key. When you’re middle-aged or older and might’t stand on one foot for no less than 10 seconds, your threat of dying within the subsequent seven years is double that of somebody who can stand for longer, in accordance with a examine of 1,700 folks.3
The Sitting-Rising Check (SRT) is one method to assess each energy and stability on the similar time.
Individuals with low scores on this take a look at have a better threat of dying from heart problems, in accordance with a 12-year examine of 4,200 adults between the ages of 46 and 75.4
▶ How you can measure it
Decrease your self to the ground together with your legs in a crisscross place. Then, together with your legs in the identical place, stand again up. As you stand, discover for those who should use part of your physique—hand, shin, knee—as leverage.
To attain your self, begin with 10 factors. Then, for every physique half you used to face, deduct a degree. Subtract a half level for those who grew to become unsteady or misplaced your stability.
Remember that this (and different assessments) function a proxy on your health. A low rating signifies that your stability and coordination, muscle energy and energy, and mobility could all require some consideration.
FREE biomarker take a look at #2: Squeeze a ball
Just like the SRT take a look at, your grip energy gives perception into your general health. If the muscle groups in your fingers are weak, the muscle groups all through your physique usually tend to be weak, too.
Poor grip energy may predict future muscle weak spot. In a single examine, folks with a weak grip have been extra more likely to stroll slowly and be unable to rise from a chair, full rigorous home tasks, or climb a flight of steps 25 years later.5
Low grip energy has additionally been related to:6
Low bone mineral density
Elevated threat of falls
Poor dietary standing
Despair
Poor sleep, cognitive operate, and/or high quality of life
Elevated threat of coronary heart illness, most cancers, and untimely mortality
In accordance with one examine, grip energy was a greater indicator of longevity (or lack thereof) than blood stress.7
▶ How you can measure it
Seize an ordinary tennis ball, and squeeze as onerous as you possibly can, for so long as you possibly can.
When you can handle 15 to 30 seconds earlier than your grip fatigues, you’re doing tremendous. Ninety seconds places you properly above common—something over 90 ranks you solidly within the upper-third percentile.
When you’re beneath 15, remember that this take a look at can also be only one indicator of your general energy. (And squeezing balls to enhance grip energy with out coaching the remainder of your physique is unlikely to make vital enhancements in your general well being and health.)
A hand-held dynamometer—out there to be used at most occupational therapists’ and a few gyms—may take a look at grip energy. (When you’re prepared to shell out some money, you should purchase your personal for someplace between $100 and $500.)
FREE biomarker take a look at #3: Stand on one foot
A capability to stability on one foot for an prolonged interval will help cut back your threat of falls, one of many main causes of injury-related demise amongst older adults.
As well as, many alternative bodily programs—the eyes, interior ear, skeletal muscle groups, and mind—should work collectively that will help you keep upright.
Circumstances like diabetes, coronary heart illness, and most cancers can all have an effect on stability. Consequently, an incapability to face on one foot can function a warning signal for eroding well being and health.8
▶ How you can measure it
Stand close to a wall or chair for security. Maintain your eyes open and fingers in your hips. Then, carry your dominant leg and begin timing your self. As soon as you place your foot down, cease the clock. Repeat the take a look at together with your non-dominant leg.
Upon getting your occasions, evaluate them to the next averages, from a examine out of Duke College, to see how you probably did in comparison with your age-matched friends.9

FREE biomarker take a look at #4: How you are feeling
Typically why you’re drained, such because the morning after binge-watching the previous few episodes of a thriller. When you compensate for your sleep, the weariness lifts.
That’s not the identical factor as fatigue, which describes persistent exhaustion that worsens over time and interferes with life. Along with feeling bodily drained, somebody who’s fatigued feels mentally uninteresting and emotionally exhausted.
Consider fatigue as an early signal that one thing’s off, particularly for those who don’t know the trigger.
Let’s say you’ve already dominated out the same old suspects like an excessive amount of caffeine, dehydration, an excessive amount of alcohol, medicine unwanted effects, power stress, or an excessive amount of or too little train. What’s left is probably going a sleep problem or a growing well being drawback resembling anemia, weight problems, melancholy, most cancers, or diabetes, to call a number of.
When you’re 60 or older, fatiguability—or how worn out you are feeling after an exercise—may predict longevity.
In accordance with analysis out of the College of Pittsburgh Medical Heart, the upper somebody scores in fatiguability, the upper their threat of demise sooner or later.10 Different analysis has linked excessive fatiguability with declines in gait velocity, strolling skill, and different assessments of health.11
▶ How you can measure it
To measure fatigability, use a software referred to as the Pittsburgh Fatigability Scale. Utilizing a 0 (no fatigue) to five (excessive fatigue) scale, charge how fatigued you assume you’d really feel after finishing the next actions:
Exercise
Length
Rating (0 to five)
Leisurely strolling

Add all scores:
When you rating lower than 15, you’re doing properly. Scores between 15 and 24 are a warning signal. Something 25 and above is considered extreme, and value mentioning to your healthcare skilled.12
FREE biomarker take a look at #5: Physique composition
Regardless of standard perception, each too little and an excessive amount of physique fats can affect well being for the more severe, as we discover in our infographic, Is physique fats good or dangerous for you?
An excessive amount of fats raises the danger for:
Too little muscle raises threat for:
Coronary heart illness

Your muscle mass additionally performs a task, which is why somebody’s physique composition issues greater than their weight.
The gold commonplace strategies that estimate physique composition—underwater weighing, air displacement (Bod Pod), and dual-energy X-ray absorptiometry (DEXA)—definitely aren’t free.
Nevertheless, a latest examine decided {that a} good old school (and low-cost) tape measure can present a comparably correct estimate of physique composition.13
▶ How you can measure it
To make use of a tape measure to maintain observe of your physique fats proportion, measure:
The widest a part of your neck
The narrowest a part of your waist (For some folks, this will likely be on the navel. For others, it may be barely above the navel)
The widest a part of your hips
Make sure the tape is comfortable however not so tight that it cuts into the pores and skin. Upon getting your measurements, plug these numbers—alongside together with your age, intercourse, top, and weight—into our FREE Physique Fats Calculator, which is able to take it from there.
Physician-approved biomarker assessments
Relying on the place you reside on this planet, the next assessments will not be free. Nevertheless, as a part of routine preventative care, your insurance coverage may cowl them.
Physician-approved take a look at #1: Blood panel
In case your main care physician recommends yearly blood work, it’s for good motive.
By maintaining tabs on a number of blood markers, you possibly can see in case your well being is trending towards kind 2 diabetes or coronary heart illness, each main causes of untimely mortality.
Many blood markers can be influenced comparatively rapidly (inside 6 to 12 weeks) by way of way of life modifications, complement protocols, or drugs. This makes them sensible instruments for monitoring whether or not numerous way of life or medical modifications are working.
▶ How you can measure it
When you’re not already doing so, think about having the next blood markers examined yearly. Then, speak to your well being care skilled about what your numbers imply. They could use the next numbers, alongside together with your blood stress, to calculate a heart problems threat rating.
Blood marker

Complete ldl cholesterol
< 200 mg/dL*
LDL
< 100 mg/dL for these with out coronary heart illness< 70 mg/dL for these with a historical past of coronary heart assault or stroke

Physician-approved take a look at #2: Bone density
When researchers examine wholesome super-agers aged 90 and older, robust bones are one among their defining options.14
That could be as a result of, like muscle groups, bones are dwell organs that secrete substances that could be useful to general well being and longevity.15
For instance, bones secrete osteocalcin, a hormone that performs a task in bone reworking. When osteocalcin circulates within the physique, it’s thought to play a task in all the things from serving to muscle groups to supply ATP to regulating mind neurotransmitters.
Due to these assorted roles, it’s thought that, as bones put on away, osteocalcin ranges drop, contributing to many age-related well being issues, together with diabetes, low muscle mass, and cognitive points.16 17 (At the very least, that’s the idea. Most of this analysis has been accomplished on mice.)
Osteocalcin apart, lack of bone density can, in fact, result in fractures, which might improve your threat of demise for as much as 10 years after a break.18
It’s particularly vital to maintain tabs on bone well being for those who’re in any of those high-risk classes:
You’re feminine and went by way of menopause earlier than age 45.
You’ve been sedentary most of your grownup life.
You’re taking drugs resembling diuretics or stomach-acid blockers, that are linked with an elevated threat of osteoporosis.
You might have a historical past of nicotine use or extreme alcohol consumption.
You might have a medical situation, resembling diabetes or thyroid illness, that raises your threat.
You might have a household historical past of osteoporosis.
▶ How you can measure it
Twin-energy X-ray absorptiometry (DEXA) scans are a sort of X-ray that measures the quantity of bone mineral content material packed right into a sq. centimeter of bone.
Insurance coverage usually received’t cowl these scans for folks youthful than 65 except there’s a documented threat of growing osteoporosis. Out of pocket, the typical value is about $300.
If you obtain your DEXA outcomes, you’ll see a T-score that represents how your bone density compares to the typical bone density of a younger grownup with peak bone mass. A T-score of +1.0 to -1.0 means you will have regular bone mineral density for somebody your age. Something beneath -1.0 means you may need osteopenia (low bone mineral density) or osteoporosis (porous bones which can be vulnerable to fracture).
Industrial bio age assessments
You probably have some cash to burn, you possibly can study an terrible lot about your physique.
Right here, you’ll discover a fast run-down on among the extra high-tech assessments you may get and what they will inform you.
Nevertheless, earlier than we get into the main points, we wish to level out a number of caveats:
▶ Organic age can range over time, and by organ. Somebody could undergo a interval of accelerated ageing—saying, throughout a interval of intense stress—then their charge of ageing could gradual as they focus extra on restoration. Moreover, organs can age at totally different charges. For instance, somebody with coronary heart illness could have a comparatively older coronary heart than their kidneys. (Not all assessments measure particular person organ age, but it surely’s turning into extra frequent.)
▶ Industrial assessments received’t all the time precisely mirror the modifications you’re making. Till extra analysis helps the reliability of those assessments, consider your behaviors over remoted take a look at outcomes. When you’re consuming extra fruits and veggies, exercising extra constantly, managing stress, and in any other case slaying the wholesome way of life division, don’t sweat your outcomes. Give attention to doing the issues we all know enhance well being.
▶ If an organization pairs your take a look at outcomes with a tough promote for a proprietary and costly complement protocol, be cautious. It’s higher to share and focus on your outcomes with a trusted well being skilled than take well being recommendation from a profit-seeking stranger over the web.
Industrial take a look at #1: DNA methylation
DNA methylation is a organic course of that chemically alters DNA. As a result of the speed of methylation accelerates with ageing, it may be used to estimate somebody’s organic age and life expectancy, finds analysis.19 20 21
The Horvath Clock and DunedinPACE each measure particular biomarkers that can be utilized to raised perceive somebody’s methylation charge. Scientists developed these assessments to assist different scientists examine how numerous way of life elements, environmental exposures, and medicines have an effect on ageing. They didn’t develop the assessments as a means for the typical particular person to pinpoint their organic age. (Which hasn’t stopped corporations from promoting DNA methylation testing kits to the general public.) They value about $300.
When you determine to get one among these assessments, take into account your outcomes received’t provide you with a whole image of your well being and longevity. Growing old usually happens at various charges all through the physique. Your liver may age sooner than your coronary heart or mind, for instance. So for those who measure DNA methylation in your blood, that’s all about. Put one other means, a DNA methylation take a look at isn’t an alternative to your annual wellness checkup or blood work.
Industrial take a look at #2: Telomere evaluation
Telomeres—the protecting caps on the ends of chromosomes—put on away with age. The size of a telomere can predict what number of occasions a particular cell can divide earlier than dying.
Abnormally brief telomeres are related to a number of genetic illnesses. Because of this, when physicians suspect somebody may need inherited a genetic illness, they’ll order a particular kind of telomere take a look at—the flow-FISH take a look at—to measure the telomere size in all of the cells in a blood pattern.22 23
It’s extra debatable whether or not telomere assessments can predict ageing in wholesome folks.
Simply as importantly, the telomere take a look at marketed to the general public, often called the qPCR telomere take a look at, isn’t utilized in analysis or medication. These $100 assessments are tremendous for those who’re merely curious—simply don’t base well being and health selections in your outcomes.
Industrial take a look at #3: VO2 Max
For years, solely elite athletes cared about VO2 max, which describes the utmost quantity of oxygen that your physique can use throughout train.
Extra not too long ago, nevertheless, some consultants have recommended that VO2 max can function a measure for athletes and non-athletes alike to trace the speed at which their our bodies are ageing.
Individuals with excessive VO2 max have a tendency not solely to be extra bodily match but additionally much less more likely to develop coronary heart illness, diabetes, most cancers, or stroke.24 25 26 27
In an observational examine that adopted the well being outcomes of 5,107 Danish males over 46 years, males with above-average V02 max throughout center age lived a mean of 5 years longer than males with below-average V02 max. Every unit improve in VO2 max was related to a 45-day improve in longevity. The researchers recommended VO2 max could extra precisely predict all-cause mortality than excessive ldl cholesterol, weight problems, hypertension, and insulin resistance.28
You may consider V02 max as a canary and your ageing physique as a coal mine.
As you age, your chest wall turns into extra inflexible, the muscle groups that encompass the lungs weaker, and the oxygen-carrying blood vessels calcified and fewer elastic. The guts additionally squeezes with much less power, max coronary heart charge drops, muscle mass and energy decline, the mitochondria in cells and muscle groups lose their effectiveness, amongst different variations.
Along with elevating your threat for a lot of totally different illnesses, these modifications may have an effect on VO2 max, which tends to say no 10 % per decade beginning round age 30.29 30
Prior to now, the one method to reliably measure VO2 max was in a health lab.
You’ll put on a metabolic masks and a coronary heart monitor whilst you ran or cycled to exhaustion. The masks collected your expired carbon dioxide and monitored how a lot oxygen you sucked into your lungs. This lab-based testing remains to be probably the most correct method to measure V02 max in addition to different key health metrics resembling:
Max coronary heart charge, or the best variety of occasions your coronary heart can beat per minute throughout train
Ventilatory threshold 1, or the purpose throughout train when the physique switches from primarily utilizing fats for gasoline to utilizing a mixture of fats and glucose or glycogen (saved glucose) for gasoline.
Ventilatory threshold 2, or the purpose the place your physique strikes away from cardio metabolism (which makes use of oxygen) to anaerobic metabolism (which doesn’t use oxygen).
Tidal quantity is the quantity of air inhaled or exhaled throughout every breath
Relying on the place you reside, you may be capable to get your VO2 max examined for round $150.
Nevertheless, for those who don’t have entry to a VO2 max clinic, three considerably much less correct choices exist.
▶ The 1-mile stroll take a look at
Put on a coronary heart charge monitor as you stroll one mile on a flat floor, resembling a treadmill or working observe. As quickly as you full the mile, document your coronary heart charge and stroll time. Then, plug it into the next formulation to calculate your VO2 max:
132.853 — (0.0769 × Weight) — (0.3877 × Age) + (6.315 × Intercourse) — (3.2649 × Time) — (0.1565 × Coronary heart charge)
If that appears like an excessive amount of math, you may also use a free on-line software.
▶ The smartwatch take a look at
Many smartwatches will estimate your VO2 Max for you based mostly on info the watch gathers out of your exercises, intercourse, and age. In comparison with in-office testing, good watches can over- or underestimate V02 max, particularly in people who find themselves very out of practice or extraordinarily match.31
Due to this, you don’t essentially wish to use your good watch measurement to find out your present state of well being. Nevertheless, it could actually enable you to see tendencies. For instance, does your VO2 estimate drop after a number of weeks of skipping your traditional spin class? If that’s the case, that’s good info to have.
▶ The PR take a look at
Health efficiency correlates with longevity. When you’re getting sooner at working a sure distance or can go an extended distance than earlier than, you’re getting fitter and growing your probabilities of residing an extended, wholesome life.
One method to take a look at this: the 12-minute run take a look at, often known as the Cooper take a look at. (This can be a validated method to estimate VO2 max—and exhibits a few 90 % correlation with lab-based measurements.)
Right here’s the way it works:
Run as quick as you possibly can on a flat floor, resembling a treadmill set at a 1 % incline or working observe, for 12 minutes. After 12 minutes, document your distance. Then, plug it into one of many following formulation to calculate your VO2 max.
Distance in Miles
Distance in Kilometers
VO2 Max =
(35.97 x distance in miles) – 11.29
(22.351 x distance in kilometers) – 11.288
In lieu of doing math, you may also use a free on-line calculator.
How you can change your organic age
Attempt to think about the knowledge you collect about your physique as simply that—info.
It’s not an ethical judgment of who you’re as an individual.
Simply as importantly, it’s not a everlasting state of affairs.
When you’re weaker than different folks your age, you possibly can develop stronger.
In case your ldl cholesterol or blood glucose ranges are excessive, you possibly can take steps to decrease them.
In case your physique is ageing sooner than your birthdays, think about exploring key way of life modifications that will assist flip the state of affairs round.
You might have choices. Nevertheless, most individuals make two large errors in relation to longevity-related way of life modifications.
Mistake #1: Ignoring evergreen, big-impact methods
It’s the easy, boring, “I’ve heard this one million occasions earlier than” well being practices that, when accomplished constantly, add as much as an extended, wholesome life.
We’re speaking about issues like…
Consuming extra minimally processed meals and fewer ultra-processed meals
Consuming extra brightly coloured fruits and veggies
Shifting your physique frequently
Getting sufficient relaxation and sleep
Having fun with group, time in nature, and different actions that make life significant
Preserving alcohol consumption average
Not utilizing tobacco
Sporting sunscreen
Flossing
And that’s only a partial record.
In accordance with 1000’s of research, individuals who apply these and different high-impact methods not solely dwell longer, but additionally dwell higher. They’re stronger, happier, and fewer more likely to spend their later years disabled or in ache.
(When you’d prefer to see the place you stand in relation to large affect well being and longevity methods, take a look at our FREE Longevity Evaluation.)
Nevertheless, in relation to well being, health, and longevity, many individuals pursue choices with minimal affect (at greatest). They attain for the most recent, fashionable complement quite than taking steps to stop smoking, as only one instance.
Right here’s the factor: Massive rock methods require modifications in habits. If each day bodily exercise have been as simple as popping a tablet, walkers and cyclists would clog up the streets in your neighborhood.
(It’s exactly this motive why so many individuals want the assist of a licensed well being coach who has undergone coaching within the science of habits change.)
Mistake #2: Not turning information into motion
The info gathered from biomarker ageing assessments can provide you a way of management.
Nevertheless…
Knowledge, in isolation, doesn’t result in an extended life.
Gathering information with out altering your habits is like checking your reflection within the mirror, seeing spinach wedged between your incisors, and leaving it there.
It’s worthwhile to take away the spinach for the mirror test to be worthwhile.
Biomarker testing is identical.
When you don’t use your bio information to tell habits change, you’re losing your time and money.
Contemplate your biomarker information as a baseline or place to begin.
Then, use it to evaluate whether or not numerous way of life modifications or medical interventions are shifting you nearer to your purpose of residing an extended, more healthy life.
