Geviti vs Function Health: Which Platform is Right for You?
Personalized health optimization is booming, and two major players, Function Health and Geviti, offer different takes on lab testing, follow-up care, and overall longevity support. If you've heard about both but aren't sure which is the better fit, this guide highlights the unique features of each program, including the biomarker breakdown, pricing, and the type of support you can expect.
Why Health Optimization Matters
Before diving into the details, let's set the stage: health optimization is about more than just blood tests and lab results. Functional health is a key component of modern health optimization, focusing on personalized healthcare approaches, longevity strategies, and comprehensive health management.
It's about a holistic approach to preventative healthcare, where you regularly measure biomarkers, receive personalized insights, and take immediate action to improve health outcomes. Functional medicine emphasizes prevention, early detection, and addressing root causes, offering a tailored and integrative approach that goes beyond conventional medicine.
With that in mind, understanding each platform's strengths, and where one might outshine the other, can guide you toward the best program for your individual goals. The landscape of preventative health and longevity medicine continues to evolve rapidly, with AI and technology enabling more data-driven, personalized health insights.
Function Health: A Health Snapshot
Overview
Function Health aims to help you "live 100 healthy years" by offering once-a-year comprehensive testing for over 100 biomarkers, plus a follow-up test of about 60 biomarkers several months later. Function Health was co-founded by Mark Hyman, a leader in functional medicine.
The initial Function Health panel includes 100+ biomarkers, with a follow-up panel of about 60 biomarkers 3 to 6 months later. The $365 annual membership fee covers access to over 100 lab tests each year. Function Health is HSA/FSA eligible.
Core Benefits
- Wide Biomarker Range
Function Health's first panel covers more than 100 biomarkers, providing a whole body assessment that includes kidney function, detailed LDL fractionation, thyroid, hormones, and advanced urinalysis. You'll see a broad snapshot of metabolic, cardiac, kidney, and autoimmune markers in one go.
- Straightforward Data Dashboard
Test results appear in an easy-to-read interface that helps you interpret your blood work and spot trends across multiple body systems over time.
- Cost-Effective Entry Point
An annual fee of $365 for two lab sessions (one full, one follow-up) offers a clear, upfront cost structure that’s easy to manage.
Main Limitations
- Limited Follow-Up and Treatment
Function Health delivers lab data and basic guidance. If you need interpretation, coaching, or treatment, you'll have to bring your results to a separate provider.
- No At-Home Testing
You must visit a Quest Diagnostics location for each draw, which can be inconvenient if scheduling or travel is a challenge.
- Only Partial Coverage of Some Markers
You get some advanced testing, like cholesterol particle size, but miss other important biomarkers like vitamin B12 and progesterone. Additionally, many essential biomarkers only get tested once per year, notably hormones, thyroid, and nutrients.
- Long Wait Times
It takes about 3-4 weeks to get bloodwork results back.
- No Wearable Integration
Currently, there's no direct link with devices like Apple Health, Oura, or Garmin, so your daily metrics remain separate from your Function Health results.
Geviti: A Comprehensive Health Optimization Solution
Overview
Geviti offers a more involved approach, combining comprehensive biomarker testing with ongoing medical support, coaching, and lifestyle guidance. Rather than just handing you data, Geviti makes it easy to act on it, whether that means adjusting your diet, starting custom supplements, or exploring prescription therapies.
Geviti offers two ways to use the platform: a free tier for a la carte testing and a Plus membership for the full clinical experience. The free platform gives you access to bloodwork, specialty tests, and supplements without a subscription. Plus members get everything included in the free tier, along with twice-yearly bloodwork, personalized video reviews from a dedicated Longevity Specialist, access to prescription therapies like HRT and peptides, and a 40% discount on supplements.
Geviti emphasizes at-home blood draws through mobile phlebotomy, offering a convenient alternative to traditional lab visits. Their comprehensive testing covers multiple systems of the body for a holistic assessment. Plus members also get wholesale pricing on peptides and discounts on supplements, making it more cost-effective compared to standard markups.
Core Benefits of Geviti
- Broad Yet Targeted Biomarker Coverage
Geviti's Longeviti Panel measures 100+ different markers, including everything from thyroid hormones (T3, T4, TSH) and metabolic markers (HbA1c, insulin) to essential vitamins (B12, Vitamin D) and advanced lipids (LDL, HDL, ApoB). Plus members get the exact same comprehensive test every 6 months, instead of a smaller second test. Test results are also available much sooner, typically in about 5-10 business days.
- In-House Interventions and Personalized Plans
Unlike Function Health, Geviti offers direct medical guidance. Plus members can meet with specialists 1-on-1 and get treatment right away. If your tests show a hormonal imbalance, Geviti can prescribe relevant therapies (such as supplements, peptides, or hormone treatments) and adjust your regimen in real time.
- At-Home Testing and Wearable Integration
Many members choose at-home blood draws for added convenience (available in most cities and suburbs), and Geviti's platform can integrate data from devices like Apple Health and Oura, giving you a more continuous view of your well-being.
- Coaching and Check-Ins
With Geviti Plus, you don't just get numbers. You also have ongoing access to a dedicated Longevity Specialist who helps you interpret, adapt, and optimize your care plan between testing rounds.
Pricing and Value
Geviti Free Platform: No monthly fee. Pay only for what you order. Free users can purchase the Longeviti Panel ($350), specialty tests, and supplements at retail pricing. Results come with an AI-generated health plan.
Geviti Plus Membership: $899 for 6 months or $1,529 for a year. Includes the Longeviti Panel every 6 months, personalized video reviews from your Longevity Specialist, a custom health and supplement plan, virtual appointments, access to HRT and peptides at provider discretion, 40% off supplements, and access to specialty testing.
Function Health, by comparison, has a fixed annual cost of $365. Both Geviti and Function Health are HSA/FSA eligible. Members can submit itemized invoices for reimbursement instead.
While you may spend more upfront with Geviti Plus, many members find the added services worth the investment when you factor in twice-yearly comprehensive testing, continuous specialist access, and in-house treatment options. If you'd otherwise pay separate doctors and specialists for guidance, bundling everything into one membership can actually be more cost-effective in the long run.
Biomarker Breakdown: A Closer Look
Geviti and Function Health are two companies at the forefront of advanced medical testing services, providing patients with access to comprehensive lab tests and diagnostics that go beyond traditional healthcare offerings. Both platforms offer extensive biomarker panels designed for health optimization and longevity, making it easier for individuals to gain deep health insights and personalized protocols. Biomarker testing through these services can help monitor early indicators of diseases such as diabetes, cancer, and cardiovascular issues.
Here's a quick overview of how Function Health's lab tests compare to Geviti's. While both panels measure many of the same items, like cholesterol, blood sugar, and sex hormones, each service has its unique extras.
Function Health Highlights
- LDL Fractionation: Breaks down LDL into small, medium, and large sub-particles
- Comprehensive Urinalysis: Repeated two times a year
- Omega-3/6 Ratios: Reflects fatty acid balance
- Smaller second test: Midyear test does not include hormones, thyroid, or key nutrients
Geviti Highlights
- Twice-Yearly Consistency (Plus members): All 100+ markers tested each round, ensuring a more thorough recheck every six months
- B12 and Progesterone: Direct measurement of vitamin B12 (rather than using a proxy like methylmalonic acid) plus progesterone testing for both men and women
- At-Home Convenience: Option for lab draws at home, which Function Health does not offer
- Follow-Through: Built-in support to address abnormal results immediately, including hormone therapy or peptide prescriptions (Plus members)
Which Health Optimization Program Is Right For You?
If You Want Testing Without Follow Up
Function Health's panels are simple and straightforward. If all you want is numbers, Function may be the right choice. Just remember that it doesn't come with in-house treatment or appointments with a specialist.
Geviti's free platform also works well here. You can purchase the Longeviti Panel or specialty tests a la carte without committing to a membership, and you'll receive an AI-generated Blueprint with your results.
If You Want Actionable Data and Regular Check-Ins
Geviti Plus is designed for this. You get an in-depth look at 100+ biomarkers twice a year, then a plan put into motion right away. Whether it's balancing hormones, adding personalized supplements, or introducing peptides, you'll have a dedicated Longevity Specialist to guide you through every step. Telehealth services like Geviti provide access to a wide range of lab tests that are often difficult to obtain through traditional healthcare channels, empowering you to take control of your health with detailed biomarker insights.
If Convenience Matters
Geviti's at-home testing can be a game-changer for those with an on-the-go lifestyle. From at-home testing to virtual appointments, Geviti comes to you. If you'd prefer a more traditional lab visit experience, Function Health may be a better fit since members are required to visit a Quest Labs location. (However, Geviti members also have the option to simply request a requisition and perform the blood draw at any Quest location nationwide.)
If You Want Custom Supplements
Geviti looks at your biomarkers and creates a custom supplement plan to address things like nutrient deficiencies, hormonal imbalances, gut issues, and more. Geviti partners with Xymogen, one of the most well-researched supplement companies in the industry, to provide professional-grade supplements to their members. Free and Plus members can purchase their supplement plan right from the Geviti app, and Plus members get a 40% discount. Function Health, by contrast, only provides basic nutrient recommendations and leaves the shopping, brand research, and purchasing entirely up to you.
If Cost is Your Top Priority
Function Health's $365 annual membership stands out for budget-focused consumers who mainly want data. Geviti's free platform also works well if you want to try a single test before committing. You can purchase the Longeviti Panel for $350 with no subscription required.
However, by bundling testing, consultation, and treatment all in one membership, Geviti Plus might be more cost-effective in the long run, especially if you'd otherwise pay separate doctors and specialists for guidance.
Conclusion
Both Function Health and Geviti are major contenders in today's health optimization market. Function Health provides a broad suite of biomarkers but leaves most treatment and follow-up in your hands. Geviti, on the other hand, offers a robust system that tests all biomarkers and provides direct interventions, comprehensive coaching, and the ease of at-home labs and specialty testing.
When it comes to health and longevity, relying on just one test is not sufficient. Ongoing, comprehensive testing is essential for accurate assessment and long-term results. A well-rounded, ongoing health optimization program may be the key to preventing chronic illness and boosting energy. Individuals are increasingly embracing data-driven programs that help them feel their best at every stage of life.
If you're looking for an all-in-one solution that not only delivers lab results but also turns those results into a real plan for longevity, Geviti is likely the better fit.
