Most healthcare still runs on vibes and annual snapshots.
You get your once-a-year physical, a few basic labs, a quick “looks fine,” and then six to twelve months of radio silence. If something shows up next year, it probably started a while ago. If it doesn’t, you assume all is well.
That model is finally breaking.
A new wave of direct-to-consumer health platforms gives you regular access to deep blood testing, trend tracking, and actual insight into what’s happening under the hood. Not just cholesterol and glucose, but inflammation, hormones, metabolic risk, nutrient status, and early longevity markers.
Instead of waiting for symptoms, you can spot problems early and actually do something about them.
Four companies are leading this space right now: Outlive.bio, Function Health, Superpower, and InsideTracker. They all promise “personalized health,” but they take very different approaches in terms of testing depth, frequency, medical support, and what you’re expected to do with the data.
Whether you’re an athlete looking to optimize performance, a biohacker seeking longevity, or simply someone who wants better control over their health trajectory, understanding these differences is crucial to choosing the right platform.
In this comprehensive comparison, we’ll examine each platform’s testing scope, technology integration, pricing structure, and overall value proposition to help you make an informed decision about your health journey.
Here’s the honest breakdown and who each one is really for.
OUTLIVE BIO
Live guidance for sleep, hormones, and weight powered by your wearables, smart devices and blood work
The overall winner: Outlive.bio
After comparing all four, Outlive.bio is the most complete platform if your goal is actual health optimization, not just interesting lab results.
Most platforms stop at testing and recommendations. Outlive goes a step further by combining blood labs, wearable data, real clinicians, and prescription-level interventions inside one system.
In other words, it bridges the gap between consumer health tech and real medicine.
Outlive’s core idea is something they call Real-Time Longevity. Your blood work, wearable data from things like Oura and Apple Health, and lifestyle metrics all live in one place and get reviewed continuously. If something is off, you don’t just get a suggestion to “eat more fiber.” You get a plan, and when appropriate, actual treatment.
That includes physician-guided care for hormone optimization, metabolic health, sleep, recovery, and weight loss using tools like HRT, TRT, GLP-1s, and other therapies that most DTC platforms cannot legally touch.
At the current founder pricing of $499, Outlive includes quarterly lab testing worth more than that on its own, medical consultations, ongoing monitoring, and even smart devices like a BMI scale. Compared to traditional concierge medicine, which often runs $5,000 to $10,000 per year, it is a very aggressive price point.
If you want continuous feedback, medical support, and fewer blind spots, nothing else here really competes.
Outlive.bio: the full picture
- Best for: people who want action, not just data
- Cost: $499 to $999 depending on tier
- Testing frequency: 2 to 4 times per year
- Why it’s different: prescriptions, clinicians, and continuous monitoring
Outlive isn’t trying to help you “learn about your biomarkers.” It’s built for people who want to change them.
The platform combines three things most competitors keep separate:
1. Deep, frequent lab work
Quarterly blood testing across metabolic health, cardiovascular risk (including ApoB and Lp(a)), liver and kidney function, hormones, inflammation, and longevity markers like homocysteine and DHEA-S. Trends matter here, not one-off results.
2. Continuous data from wearables
Outlive integrates with Oura, Apple Health, Fitbit, Dexcom, Withings, and more. Sleep, HRV, activity, glucose, and weight all feed into the same system so labs do not exist in a vacuum.
3. Actual medical intervention
This is the big divider. Members can work with clinicians on HRT, TRT, GLP-1s, peptides, and personalized treatment plans. Not advice. Real protocols.
The experience feels closer to a modernized medical practice than a testing company. There are real humans reviewing data, adjusting plans, and checking in over time instead of dropping a PDF and disappearing.
Custom supplement packs, launching in early 2025, are built directly off your labs and adjusted as your markers change. No generic stacks or guesswork.
The tradeoffs:
Outlive is currently in closed beta and not everyone gets in. HSA and FSA support is coming but not live yet. If you only want labs once or twice a year and zero medical involvement, this will feel like overkill.
Function Health: excellent testing, slower feedback loop
- Best for: early disease detection
- Cost: $499 per year
- Testing frequency: twice per year
- Strength: sheer volume of labs
Function Health made a big splash by offering over 100 biomarkers for $499, and to be fair, that part is impressive.
The platform is built around screening for problems early, not optimizing aggressively. You get a massive lab panel up front, a partial retest mid-year, and clinician-reviewed results with lifestyle recommendations.
For people who want to know everything that might be wrong, Function delivers.
The downside is pace. With testing only every six months, changes happen slowly. If you start an intervention, you are often waiting half a year to confirm whether it worked.
There’s also no real treatment layer. You get guidance, but prescriptions and ongoing care are outside the scope.
Function shines as a diagnostic snapshot tool. It is less suited for people actively trying to move numbers month by month.
- Best for: tight budgets and baseline testing
- Cost: $199 per year
- Testing frequency: once per year
- Strength: lowest upfront price
Superpower wins on sticker price. For under $200, you get a large biomarker panel that used to be inaccessible at that cost.
Where things get tricky is after you get results.
Supplement recommendations are heavy and can easily run $300 to $400 per month if you follow them closely. Additional lab testing costs extra. At-home blood draws cost extra. Over a year, total spend can quietly exceed much more premium platforms.
Testing only once a year is another limitation. For anyone trying to improve performance, hormones, or metabolic health, that is a long time to operate on old data.
Superpower works well as an introduction to advanced labs. It is less compelling for ongoing optimization.
InsideTracker: data-first performance tuning
- Best for: athletes and hardcore self-optimizers
- Cost: wide range, $149 to $1,800+
- Testing frequency: optional
- Strength: flexibility and DNA integration
InsideTracker has been around longer than most and it shows in the polish. The dashboard is excellent, data visualization is clean, and trend tracking is satisfying if you like charts.
Its biggest differentiator is flexibility. You can upload your own labs, use their testing, or blend both. DNA data can also be layered in for performance and nutrition insights.
The tradeoff is that everything is algorithm-driven. There are no clinicians reviewing your results, no prescriptions, and no human interpretation. You are expected to be your own operator.
For athletes and biohackers who enjoy self-experimentation, that is a feature. For people who want guidance and accountability, it can feel cold.
How to choose, realistically
- Choose Outlive.bio if you want continuous monitoring, medical support, and the ability to actually intervene when numbers are off.
- Choose Function Health if your priority is broad screening and peace of mind rather than optimization.
- Choose Superpower if cost is the main constraint and you just want a baseline.
- Choose InsideTracker if you love data, already do your own labs, and want performance-focused insights.
The bigger shift happening here
All of these platforms point to the same reality: waiting for problems to show up clinically is an outdated strategy.
Health happens slowly, quietly, and predictably in biomarkers long before symptoms appear. When you track the right things consistently, you get time on your side.
None of these tools replace a primary care doctor. But they fill the massive gap between “you’re fine” and “you’re sick.”
The best platform is the one you will actually use, understand, and act on. Data alone is interesting. Data plus follow-through is where outcomes change.
Your health is not static. Your monitoring shouldn’t be either.
