Function Health vs. Geviti: Which Health Optimization 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. 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. 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.

Function Health: A Quick Overview

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. At $499 a year, it’s budget-friendly and even accepts HSA/FSA cards.

Core Benefits

1. Wide Biomarker Range
   Function Health’s first panel covers more than 100 biomarkers, including detailed LDL fractionation, thyroid hormones (T3, T4, TSH, and antibodies), and advanced urinalysis. You’ll see a broad snapshot of metabolic, cardiac, and autoimmune markers in one go.
   
2. Straightforward Data Dashboard
   Test results appear in an easy-to-read interface so you can spot trends and track changes over time.
   
3. Cost-Effective Entry Point
   An annual fee of $499 for two lab sessions (one full, one follow-up) offers a clear, upfront cost structure that’s easy to manage.
   

Main Limitations

1. Limited Follow-Up and Treatment
   Function Health delivers lab data and basic guidance. If you need hormone therapy or deeper medical interventions, you’ll have to bring your results to a separate provider.
   
2. 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.
   
3. Only Partial Coverage of Some Markers
   You get advanced LDL details and autoimmune screens, but certain nutrients and hormones (like vitamin B12 or progesterone in men) aren’t a main focus. Additionally, most hormone panels are tested only once a year.
   
4. Wearable Integration
   Currently, there’s no direct link with devices like Apple Health, Oura, or Whoop, 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 twice-yearly 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 peptide therapy, or exploring hormone optimization.

Core Benefits of Geviti

1. Broad Yet Targeted Biomarker Coverage
   Every six months, Geviti measures 94–96 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). While Geviti may not break down LDL into small, medium, and peak sizes like Function Health, it covers all the primary markers you need to make informed health decisions.
   
2. In-House Interventions & Personalized Plans
   Unlike Function Health, Geviti offers direct medical guidance. If your tests show a hormonal imbalance, Geviti can prescribe relevant therapies (such as peptides or hormone treatments) and adjust your regimen in real time.
   
3. At-Home Test Kits & Wearable Integration
   Many members choose at-home blood draws for added convenience, and Geviti’s platform can integrate data from devices like Apple Health and Oura, giving you a more continuous view of your well-being.
   
4. Unlimited Coaching & Check-Ins
   With Geviti, you don’t just get numbers; you also have ongoing access to health coaches and clinicians who help you interpret, adapt, and optimize your care plan between testing rounds.

Pricing and Value

Geviti's membership costs $110–$130 per month, which includes all lab work, results consultations, and access to the personalized interventions at wholesale cost. That might seem like more than Function Health’s yearly membership, but when you factor in unlimited coaching, medical follow-ups, and in-house treatment options, many members find the added services worth the investment.

Biomarker Breakdown: A Closer Look

Here’s a quick overview of how Function Health’s 100+ tests compare to Geviti’s 94–96. 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.
• Autoimmune Markers: Tests like ANA and rheumatoid factor.
• Comprehensive Urinalysis: Repeated two times a year.
• Omega-3/6 Ratios: Reflects fatty acid balance.

Geviti Highlights

• Twice-Yearly Consistency: All 94–96 markers tested each round, ensuring a more thorough recheck every six months.
• B12 & 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.

Which Health Optimization Program Is Right For You?

1. If You Want the Broadest Possible Lab Snapshot in One Shot
   Function Health’s first panel (with over 100 biomarkers) is compelling—especially if you’re curious about advanced LDL size patterns or specific autoimmune markers. Just remember that it doesn’t come with in-house treatment or continuous support.
   
2. If You Want Actionable Data and Regular Check-Ins
   Geviti’s approach aims to give you an in-depth look at relevant biomarkers twice a year, then put a plan into motion right away. Whether it’s adjusting hormones, adding personalized supplements, or introducing peptides, you’ll have a dedicated team to guide you through every step.
   
3. If Convenience Matters
   Geviti’s at-home testing can be a game-changer for those with an on-the-go lifestyle. If you’d prefer a more traditional lab visit experience, Function Health may be best as 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 from a Quest or LabCorp).
   
4. If Cost is Your Top Priority
   Function Health’s $499 annual membership stands out for budget-focused consumers who mainly want data. However, for a more hands-on plan that includes medical treatment, Geviti 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—some of which are quite specialized—but leaves most treatment and follow-up in your hands. Geviti, on the other hand, offers a robust system that tests all critical markers twice a year and provides direct interventions, comprehensive coaching, and the ease of at-home labs and specialty testing.

If you’re looking for an all-in-one solution—one that not only delivers lab results but also turns those results into a real plan for longevity—Geviti is likely the better fit. But if you’re comfortable self-managing your care and want maximum biomarker variety in a single snapshot, Function Health may do the trick.
