Why the DunedinPACE Clock Is the Future of Longevity Testing
Discover why the Blueprint Speed of Aging test is the most advanced tool to measure how fast you’re aging and which organs need the most attention.

Today, we want to share info about the science behind Blueprint’s Speed of Aging test. Recently, Bryan Johnson shared a detailed breakdown of why this test is different from all others, how the underlying science has evolved over the past decade, and what makes DunedinPACE the most reliable way to measure how fast you’re aging.
We did the Speed of Aging test back in January and received a biological age of 29.1 years old, despite having a chronological age of 45. The report also revealed individual ages for eleven key organs, with our lungs coming back as the youngest. Thank you years of distance running! This test provided clear, actionable insights and confirmed what other biomarker tests had hinted at, but with more precision and context.
From fun fact to serious science
We’ve had ways to test biological age for a while, but not all clocks are created equal. Bryan’s post walks through the evolution of biological age testing and why third-generation tests like DunedinPACE are a breakthrough.
First Generation: Horvath and Hannum
These clocks were trained on datasets of people at various chronological ages. They predicted age well but lacked strong ties to health outcomes or longevity.
Second Generation: GrimAge and PhenoAge
These improved on the first generation by training against health biomarkers and mortality risk, offering more meaningful predictions but still based on single-time-point snapshots.
Third Generation: DunedinPACE
DunedinPACE is the first test built from data tracking the same people from age 3 to 51. It is not just a prediction of age but a measurement of how quickly or slowly you are aging in real time.
What makes the Blueprint Speed of Aging test different
Bryan highlights four major advantages of DunedinPACE that make it stand out from all other clocks:
- Minimizes environmental noise
Because it follows the same individuals across decades, it avoids distortions caused by differences in where and when people lived. - Measures speed, not age
Rather than saying you are “biologically 43,” it tells you how fast you are aging. That makes it ideal for testing how interventions impact your trajectory. - Top predictor of real-world outcomes
It outperforms other clocks when it comes to forecasting mortality and age-related decline. - Consensus-backed across studies
In a review of 16 biological clocks across 51 intervention studies, DunedinPACE consistently aligned with the majority or was the only one to detect a meaningful change in biological age.
Final thoughts
The Blueprint Speed of Aging test is not just about knowing how old you are on the inside. It gives you real-time feedback on whether the lifestyle choices you’re making are helping or hurting. I took it back in January, and it gave me insight into both my overall aging speed and the condition of each organ system.
This is the future of health tracking. If you’re serious about optimizing your body and extending your healthspan, start here. The science is ready when you are.

Are You Poisoning Your Pet Without Knowing It? Blueprint Quantified Just Went Live
New lab results from Blueprint Quantified reveal alarming levels of glyphosate and heavy metals in top-selling dog and cat foods across the US.

Today, a quiet revolution in pet food transparency has begun. Bryan Johnson just unveiled a new initiative called Blueprint Quantified, a database that publicly tests food for toxins. The first focus: pet food. And the early findings are eye-opening for anyone who has ever trusted a brand from the pet store aisle.
This isn’t just another watchdog effort. Anyone can fund a test, and if a company already claims their product is clean, your money gets refunded. It’s a crowdsourced attempt to rapidly audit all US dog and cat foods using ISO-certified lab testing and it’s long overdue. And with this foundation in place, human food testing is likely next.
The Pet Food Contaminant Crisis
Out of 22 mass-market pet food products tested (12 dog foods and 10 cat foods), all but one contained glyphosate, and every single one contained toxic heavy metals, arsenic, cadmium, lead, and mercury.
Some of the key findings:
- Glyphosate was detected in 21 out of 22 products.
- Eight products maxed out the upper detection limit of 1,000 ppm.
- One product (Wellness CORE+ Original) hit 118,000 mcg per serving, equivalent to the maximum tolerable human exposure for a 150-pound adult in just one dog food meal.
- Heavy Metals
- Arsenic: Detected in 100% of samples. One popular wet cat food (Sheba) contained 8.9 mcg per 38 g serving.
- Lead: Royal Canin Indoor Adult Cat Food contained 343 ppb, or 12.9 mcg per serving, 26 times higher than California’s Prop 65 daily limit for lead (0.5 mcg).
- Cadmium and mercury were present in all products at varying levels.
Which Brands Were the Worst Offenders
Top products by total heavy metal toxicity per serving:
- Wellness CORE+ Original (Dog): 43.4 mcg
- Nutro Natural Choice Small Breed (Dog): 42.6 mcg
- Blue Buffalo Homestyle Senior (Dog, wet): 35.6 mcg
- Royal Canin Size Health Medium Dog: 33.7 mcg
- Pedigree Small Dog “Grilled Steak & Veg” (Dog): 27.9 mcg
And the Cleanest?
In a surprising twist, Purina Friskies Surfin’ & Turfin’ (Cat) had no detectable glyphosate and the second-lowest level of total heavy metals across all products tested. It’s a reminder that price and branding don’t always reflect quality or safety.
Why It Matters
Chronic exposure to glyphosate and heavy metals can lead to inflammation, kidney and liver dysfunction, neurological issues, and even cancer, especially in smaller animals with less capacity to detoxify. According to toxicology data, the cumulative burden of even microgram-level exposures over time can have serious consequences for pet health.
The alarming part? Most of these brands are marketed as “natural,” “premium,” or even “veterinarian-recommended.” However, lab data doesn’t lie.
How Blueprint Quantified Works
- Search: Review tested products at blueprintquantified.com
- Fund: Pay to test your pet’s food (and next will be human food). If it already has published results or the brand claims it is clean, your money is refunded
- Scale: As more users fund testing, the goal is to rapidly test all US dog and cat food and then human food.
Anyone can participate. It’s the beginning of a transparent, community-led effort to hold companies accountable and protect our pets from daily toxic exposure.
Final Thoughts
If you feed your dog or cat commercial food, you deserve full transparency about what’s inside. Blueprint Quantified is paving the way for a future where clean food isn’t a marketing claim, it’s a verified fact. These early findings are a wake-up call, but also a rare opportunity. With real data in hand, we can make informed decisions and demand higher standards from the industry. It’s time to stop guessing and start testing. And as this expands beyond pet food, we look forward to seeing the same level of accountability brought to the human food supply.

The Power of Flavonoids: How Adding Them to Your Diet Can Support Healthy Aging
A diet rich in flavonoids may reduce frailty, improve mental health, and protect mobility, based on a study of 86,000 adults over 60 years old.
Today, we’re exploring how flavonoids, powerful compounds found in certain foods, can play a key role in supporting healthy aging. You’ve probably heard of flavonoids or seen foods with them in the Don’t Die Food Guide. However, you may not know exactly what they are or why they’re important.
These naturally occurring antioxidants, found in a variety of fruits, vegetables, and plant-based foods, offer a wide array of health benefits. From reducing inflammation to protecting brain function and mobility, flavonoids are a critical part of a healthful diet. Let’s dive into why incorporating these flavonoid-rich foods, like those included in Bryan Johnson’s own diet, is essential for healthy aging.
The Flavonoid Benefits Backed by Science
A large study, examining over 86,000 adults aged 60 and above, found impressive results. The individuals who consumed the highest amounts of flavonoid-rich foods had:
- A 15% lower risk of frailty
- A 12% lower risk of physical disability
- A 12% lower risk of mental health issues
These findings support the idea that flavonoids are not just good for you, they may be a key component in promoting healthy aging. By reducing the risk of frailty and disability and improving mental well-being, flavonoids help preserve quality of life in later years.
What Are Flavonoids and Where Can You Find Them?
Flavonoids are compounds that give many fruits and vegetables their vibrant colors, and they have potent antioxidant properties. These antioxidants help combat free radicals, which can damage cells and accelerate aging processes in the body.
Bryan Johnson, who advocates for a flavonoid-rich diet, lists his top sources:
- Extra Virgin Olive Oil: Rich in flavonoids and healthy fats, this oil is an excellent addition to any meal.
- Berries: Blueberries, blackberries, and strawberries are high in flavonoids, making them perfect for smoothies, snacks, or salads.
- Pomegranate and Grape Seeds: Packed with flavonoids and other beneficial compounds, these can be added to meals or eaten as snacks.
- Walnuts: Not only do they provide flavonoids, but they’re also a great source of omega-3 fatty acids.
- Cocoa (100%): Dark chocolate or raw cocoa offers a rich source of flavonoids.
- Matcha: This green tea powder contains a high concentration of flavonoids and is a great alternative to coffee.
How Do Flavonoids Work in the Body?
Flavonoids exert their benefits by reducing oxidative stress and inflammation in the body, which are two key contributors to the aging process. By lowering inflammation, they help protect the cardiovascular system, brain health, and overall mobility. The compounds also support the gut, immune system, and can even reduce the risk of chronic diseases such as heart disease, diabetes, and certain cancers.
A recent study further reinforces the impact of flavonoid consumption on aging. The study followed participants over several years and found that higher intake of flavonoid-rich foods led to a significantly lower risk of frailty, impaired physical function, and poor mental health. Notably, these benefits were most pronounced in women, but men also saw some positive effects, particularly related to mental health.
Final Thoughts
Including flavonoid-rich foods in your diet could be a simple yet effective strategy for promoting healthy aging. Whether it’s blueberries in your morning smoothie or a drizzle of extra virgin olive oil on your salad, small changes can lead to meaningful long-term benefits. While further research is needed, especially to explore sex-specific associations, the current evidence supports flavonoids as a powerful tool in preserving physical and mental well-being as we age.

Why International Travel Is Brutal for Your Health and What You Can Do About It
Discover how international travel disrupts your sleep, metabolism, and mental health, and learn science-backed tips to protect your longevity on the road.
Today, we are uncovering the hidden health toll of international travel. Bryan Johnson recently posted research-backed insights revealing just how damaging frequent long-haul flights can be, from increased risk of blood clots to cognitive and metabolic dysfunction. If you care about healthspan and performance, this one is for you.
Inside Bryan’s Sleep Deprivation Experiment
Bryan Johnson recently returned from 11 days abroad and shared a candid, unfiltered account of how quickly sleep deprivation can dismantle even the most disciplined routines. For someone who has spent years optimizing every aspect of his biology, this personal experiment revealed just how dangerous disrupted sleep can be and why it matters for anyone who values high performance, emotional stability, and healthspan. Here’s what he experienced:
I just returned from 11 days of international travel, during which I was sleep deprived.
It was shocking to experience how ferociously cravings for bad foods spiked.
It took me back to my early entrepreneur days when it felt impossible to stop my bad eating habits. When you're sleep deprived, you become an animal and you can do little about it.
For the first few days, the cravings were present yet manageable. By day 5, they were getting irritatingly strong and by day 9, they were overwhelming.
The science of sleep deprivation and bad decision making is solid. After one night of inadequate sleep (4 to 5 hrs):
+ PFC drops by 10-20% (self-control)
+ a hyperactive 25-30% increase to eat addictive foods
+ devalue future rewards and high risk decisions
Lose one night’s sleep and your brain’s CEO (PFC) takes a 12% pay cut while the candy-craving intern gets a 25% raise.
In just a few days time of poor sleep, I became a different person.
I chose to do this experiment as I wanted to experience the effects of sleep deprivation given that I've been sleeping very well for years now.
Sleep deprivation makes you a little insane.
Though this all, I couldn't stop thinking about how most (or all?) of our world leaders are chronically sleep deprived. Culture culture wants to demands it. It's honestly concerning.
The Science Is Clear: Travel Breaks Your Body
Recent studies have shown the following:

- 3x higher risk of blood clots when flying more than 12 hours within a 4-week span
- 1.7 to 3.7 times higher risk of anxiety, depression, and alcohol dependence with 21 or more travel nights per month
- 9 days required to restore metabolic and blood glucose control post-travel
- Sleep architecture and timing may take more than 15 days to normalize
- Travelers eat worse, exercise less, and fall out of routines, compounding the health damage
Experimental studies even show that jet lag impairs neurogenesis and leads to long-term cognitive deficits in animals. A massive study using 1.5 million nights of data confirmed that international travel disrupts sleep duration, timing, and quality at nearly every stage.
Tips to Travel Internationally Without Sacrificing Your Health
If travel is unavoidable, here is how to make it less destructive:
#1 Use Time Zone Strategy
- Shift your sleep schedule 2 to 3 days before departure to match your destination
- Use melatonin short-term to ease jet lag, ideally under medical guidance
#2 Move During the Flight
- Walk and stretch every 2 hours to reduce clotting risk
- Hydrate aggressively to prevent blood viscosity increases
#3 Protect Your Metabolism
- Avoid sugary or processed meals on the plane
- Use Blueprint’s Longevity Mix Travel Packs and Essential Supplements to stay consistent with your nutrition stack
#4 Keep Sleep Sacred
- Bring eye masks, earplugs, or white noise apps to control your environment
- Try to sync with local time immediately on arrival and get sunlight exposure in the morning to reset your clock
#5 Maintain a Routine
- Schedule a daily walk, light workout, or breathwork session even if short
- Bring Blueprint’s Daily Stack Travel Packs and EVOO travel bottles to maintain continuity in your regimen
Blueprint Travel Packs
Travel Packs are designed to help you stay consistent with your longevity protocol while on the go. Whether you’re flying across time zones or navigating disrupted routines, these convenient packs include pre-portioned servings of essential nutrients, supplements, and high-polyphenol extra virgin olive oil to support metabolic health, sleep, and inflammation control. Available in formats like the Daily Stack, Longevity Mix, and EVOO Travel Packs, they make it easy to maintain your Blueprint no matter where you are in the world.
Final Thoughts
International travel disrupts more than your calendar. It compromises your body at every level. From clotting risks to brain fog, the data makes one thing clear: travel is a performance tax. But with a little planning and the right tools, you can defend your health against the chaos of jet lag and time zone whiplash. Use these strategies to travel smarter, protect your biology, and keep building a future you will not want to escape from.
