Quick answer: The best Function Health alternatives 2026 has to offer are Superpower (best overall value at about $199/year for 100+ biomarkers and ratios with clinician review), InsideTracker (best for athletes), Labcorp OnDemand (best pay-as-you-go), and Marek Health (best for optimization-focused men). Function Health now charges $365/year and includes 160+ lab tests across the year (about 100+ on your annual draw plus a 60+ marker mid-year retest). Most alternatives on this list match it on the markers that matter for the annual draw, and several cost less. The right choice comes down to whether you want a membership, a one-time draw, or a concierge physician layer on top.

Why People Are Searching for Function Health Alternatives

Function Health built real momentum after Peter Attia and others amplified the idea of annual comprehensive blood panels. But the service still has friction that pushes users to look elsewhere. Function cut its membership to $365/year in 2026 (down from $499), which helped, but it remains a membership-only model with no ongoing physician access between draws. Draws happen at Quest Diagnostics locations, and Function added at-home draws after acquiring Getlabs in 2026, so logistics improved. The bigger friction is structural, not just price.

There is also a category question: Function Health is fundamentally a data product. You get a dashboard and doctor-interpreted highlights, but the service does not prescribe, treat, or manage your care. That is fine for some users. Others want a clinician who can actually order a follow-up test or write a prescription based on what they find. Understanding that distinction is the first step toward picking the right Function Health alternative for your situation.

One more thing worth knowing: in early 2026 Function Health filed a false-advertising suit against rival Superpower over how the “100+ biomarkers” figure is counted, arguing some of that total comes from calculated ratios rather than separate lab measurements. The case shows how openly contested this category has become, with well-funded services pushing hard on price and biomarker breadth. For you as a consumer, the practical takeaway is to read what each “100+” claim actually includes, which we break down below.

How We Ranked These Function Health Competitors

Every service on this list was evaluated on four dimensions: biomarker count per draw, physician review quality, price per year for a typical user, and the logistics of actually getting blood drawn. A service that tests 150 biomarkers but requires you to drive to a single location in one city is not a practical alternative for most readers. We also weighted whether the membership structure delivers compounding value year over year, meaning trend tracking and longitudinal comparison, which is the core promise of the category.

Price ranges reflect 2026 cash pricing for a single adult. HSA and FSA dollars are accepted by most of these services, which effectively gives you a 22 to 37 percent discount depending on your tax bracket.

The 9 Best Function Health Alternatives, Ranked

1. Superpower (Best Overall)

Superpower runs a 100+ biomarker and ratio panel, has results reviewed by a licensed clinician, and tracks your numbers year over year for about $199/year (note: $399 for members in New York and New Jersey). That is well under the cost of Function Health, and the price-to-depth ratio is what puts it at number one on this list. For a clear-eyed comparison, see our Superpower vs Function Health breakdown.

The draw is done at a Quest or Labcorp location near you, which covers the vast majority of the US, with at-home draw available for an added fee. You schedule online and get a requisition form. Most users report results within a few days. The clinician review is not a chatbot: a real doctor flags abnormals, explains what is moving in the wrong direction, and notes what to discuss with your primary care provider. Read the full Superpower blood test review for the complete panel breakdown and what the draw actually looks like.

Where Superpower is not perfect: it is a data and guidance product, not a prescribing platform. If you want testosterone pellets or tirzepatide, you are going elsewhere. For the majority of people who want annual comprehensive lab work with smart interpretation, it covers the bases better than anything else at this price. See the how much does Superpower cost breakdown for a full price comparison.

2. InsideTracker (Best for Athletes and Performance)

InsideTracker tests up to 48 biomarkers on its Ultimate plan and cross-references results against age- and sport-matched peer data, which is genuinely useful if you train seriously. In 2026 it runs on a membership model: a $149/year membership, with each Ultimate blood test about $340 on top, so a year of Ultimate lands near $489. The standout feature is the personalized action plan that links your specific abnormals to peer-reviewed diet, supplement, and training interventions.

The limitation: the biomarker count is lower than Function Health. You are paying for the interpretation infrastructure and the peer comparison database, not breadth of testing. For a competitive athlete who wants to know exactly where their iron, cortisol, and Vitamin D sit relative to performance benchmarks, that trade-off is worth it. For a 45-year-old who wants a metabolic baseline, Superpower gives more data for less money.

3. Labcorp OnDemand (Best Pay-As-You-Go Option)

Labcorp OnDemand lets you order individual tests or bundles directly without a doctor’s order, at prices ranging from $29 to $299 depending on what you pick. The Wellness Complete Panel (about $149 to $199 depending on promotions) covers roughly 60 biomarkers including a lipid panel, CBC, CMP, HbA1c, thyroid, and iron. No membership required.

The big advantage over Function Health is flexibility. You are not locked into an annual subscription. You draw when you want, what you want. The big disadvantage is that Labcorp OnDemand does not provide physician interpretation. You get reference ranges and a PDF. If something is flagged, you are calling your own doctor. For healthy adults who just want periodic checks and know how to read a lab report, this is the most cost-efficient option on the list.

4. Marek Health (Best for Optimization-Focused Men)

Marek Health is a telehealth clinic that combines physician access, prescribing authority, and lab work under one roof. Its lab panels are tiered: Base around $250, Comprehensive around $450, Complete around $850, and an Executive panel around $2,000 for the most extensive work-ups. TRT programs typically run about $225 to $275 per month on top. Unlike Function Health, Marek Health doctors can prescribe TRT, peptides, and other interventions based on what they find.

This is the right choice if you are already in or considering hormone optimization and want your labs tied directly to a prescribing relationship. It is not the right choice if you want a neutral, unbiased baseline read. Marek Health sees a lot of patients who are already on or pursuing TRT, and the platform is built around that workflow.

5. Quest Health (Best Retail Accessibility)

Quest Diagnostics operates over 2,200 patient service centers nationwide and has a direct-to-consumer arm called Quest Health where adults can order tests without a prescription. Prices run from $35 to $250 depending on the panel. Their Heart Health Advanced Plus panel at around $149 to $189 covers the most important cardiovascular and metabolic markers. Quest also accepts HSA and FSA cards.

The draw at Quest is the most accessible option on this list geographically. If you live in a rural area where other services have no phlebotomy coverage, Quest is often the only viable option. Interpretation is self-serve, and there is no membership with trend tracking.

6. Levels Health (Best Metabolic Monitoring)

Levels pairs continuous glucose monitoring (CGM) with metabolic blood panels to give you a fuller picture of how your metabolic system behaves in real time rather than at a single fasting snapshot. Membership runs around $199 to $299 per year depending on the plan tier. The blood panel component covers core metabolic markers: fasting glucose, HbA1c, insulin, lipids, and inflammatory markers.

Levels is the right alternative if your main concern is metabolic health, pre-diabetes risk, or understanding how food affects your blood sugar. The CGM component is what differentiates it from every other service on this list. It is not a broad biomarker sweep, so it should not be your only annual lab draw if you want comprehensive data.

7. Everly Health (Best for Targeted At-Home Testing)

Everly Health (formerly EverlyWell) covers at-home finger-prick and saliva testing across 30-plus panels ranging from about $49 to $299. They also have a Women’s Health Test and Men’s Health Test that bundle hormones, thyroid, and key metabolic markers. Results come with a clinician-reviewed report. If at-home collection is your priority, compare it against the field in our roundup of the best at-home biomarker tests.

The convenience is real: no lab visit, no appointment, results in 5 to 7 business days. The limitation is accuracy on certain markers. Finger-prick collection introduces more variability than a venipuncture draw, which matters for biomarkers like lipids and insulin. For hormones and thyroid, the difference is smaller. Think of Everly Health as a screening layer, not a clinical-grade baseline.

8. 10x Health System (Premium Concierge)

10x Health is the high-end concierge end of this spectrum, typically pricing their comprehensive blood and genetic panel at $1,000 to $2,000+ depending on location and what is included. What you get for that price is a dedicated health coach, a physician consult to review findings, and a personalized supplement and lifestyle protocol. Biohacker influencers popularized this option.

The value proposition only holds if you actually engage with the coaching and protocol. As a pure lab draw, it is dramatically more expensive than the alternatives here. If you have already tried Superpower or InsideTracker and want a higher-touch relationship, it is worth considering. Read the full comparison at function health vs 10x health to see how the two premium options stack up directly.

9. Empirical Health (Best Budget Comprehensive Panel)

Empirical Health is a newer, physician-led entrant built around heart-disease prevention and long-term trend tracking. Its self-pay panel covers 100+ biomarkers, including ApoB, Lp(a), advanced lipids, hs-CRP, eGFR, and HbA1c, for about $190, one of the lowest prices for a panel this broad. Draws happen at 2,000+ partner labs nationwide with same-day or next-day scheduling. For a head-to-head breakdown, see function health vs empirical health.

Side-by-Side Comparison: Function Health vs Top Alternatives

Service Price/Year Biomarkers MD Review Trend Tracking Prescribing
Superpower ~$199 ($399 NY/NJ) 100+ (incl. ratios) Yes (clinician) Yes No
Function Health ~$365 160+ across year Clinician review Yes No
InsideTracker Ultimate ~$489 ($149 + ~$340) up to 48 Peer benchmarks Yes No
Labcorp OnDemand $29 to $299 per draw Varies No No No
Marek Health $199 to $500+ 30 to 80 Yes + prescribing Yes Yes
Levels Health ~$199 to $299 ~20 blood markers Partial Yes No
10x Health $1,000 to $2,000+ Comprehensive + genetics Yes + coaching Yes Sometimes
Empirical Health ~$190 100+ Yes Yes No

What Function Health Gets Right (and Where It Falls Short)

Before dismissing Function Health entirely, it is fair to note what they do well. The panel breadth, with 160+ tests spread across an annual draw and a mid-year retest, is genuinely comprehensive for a membership product. The dashboard UX is polished and the trend charts are well-designed. The result highlights are reviewed by real clinicians. For users who are already paying for concierge medicine or a health-focused financial plan, the $365 annual fee may fit naturally.

The core complaint, documented across Reddit, consumer reviews, and comparison threads, is the price-to-value ratio when you compare it to competitors testing a similar number of markers for less. Over five years, Function Health at $365/year runs about $1,825, while Superpower at $199/year runs about $995. That roughly $830 gap buys a lot of follow-up testing or specialist visits if something abnormal turns up. See our full function health cost analysis for the math.

Function Health also does not offer prescribing, doesn’t integrate with most EHR systems, and hasn’t yet built out the coaching or intervention layer that competitors like Marek and 10x have. Talk to a clinician about any abnormal results you get, regardless of which service you use. The lab membership is the starting point, not the treatment plan.

Cheaper Than Function Health: What You Actually Sacrifice

The honest answer is: often very little. The services priced below $250/year that make this list give up almost nothing on biomarker count compared to Function Health. Where the gap shows up is in software polish and brand recognition, neither of which affects the quality of your data.

At the Labcorp OnDemand level (no membership, pay per draw), you sacrifice trend tracking and interpretation. If you are disciplined enough to keep your own spreadsheet and comfortable reading reference ranges, this trade-off is practical. Most people overestimate their own discipline here. A structured membership with automated trend tracking produces more actionable longitudinal data than a folder of PDFs you periodically forget to open.

One genuine sacrifice at the lower price point: some services that are cheaper than Function Health use capillary (finger-prick) collection rather than venipuncture. For some biomarkers this matters. Lipid panels, ApoB, insulin, and IGF-1 are all more accurate from a proper venous draw. If your goal is clinical-grade data that a physician can actually act on, venipuncture from a Labcorp or Quest draw site is the standard to insist on. Superpower, InsideTracker, and Labcorp OnDemand all use standard venipuncture at patient service centers.

Which Alternative Is Best for Your Specific Situation

The right alternative depends less on rankings and more on your specific need. Use this decision guide:

  • You want maximum biomarkers with physician review under $250/year: Superpower.
  • You train seriously and want peer-benchmarked performance data: InsideTracker Ultimate.
  • You want flexibility with no subscription: Labcorp OnDemand or Quest Health.
  • You are a man interested in hormone optimization and may want TRT: Marek Health.
  • You have metabolic concerns or want CGM integration: Levels Health.
  • You want screening convenience with at-home collection: Everly Health (confirm venipuncture option for key markers).
  • You want a high-touch concierge layer with coaching: 10x Health.
  • You want quarterly trend data more than an annual snapshot: Empirical Health.

Age also matters. Adults over 55 often benefit from quarterly or semi-annual draws rather than annual ones because key markers like kidney function, glucose, and PSA can move meaningfully in six months. Services that support more frequent draws (Empirical Health, Labcorp OnDemand) give older adults more useful frequency flexibility than annual-only memberships.

Medicare does not currently cover direct-to-consumer membership lab services, including Function Health and Superpower. If you are on Medicare, your annual wellness visit (AWV) includes a basic lab panel, and your doctor can order additional tests with a clinical indication. The DTC membership services are out-of-pocket regardless of insurance status, but HSA and FSA dollars are accepted by most of them.

FAQ

What is the best alternative to Function Health in 2026?

Superpower is the best overall alternative to Function Health in 2026 for most adults. It runs a 100+ biomarker and ratio panel, includes clinician review of results, enables year-over-year trend tracking, and costs about $199/year compared to Function Health’s $365/year. For athletes, InsideTracker is stronger on performance benchmarking. For men wanting prescribing access, Marek Health adds a clinical intervention layer.

Is there a cheaper version of Function Health that does the same thing?

Superpower comes closest to replicating Function Health’s core offering at roughly 45 percent less cost ($199 vs $365 per year). Both report 100+ biomarkers, provide clinician-reviewed results, and track your numbers over time. The main difference is that Function Health spreads its testing across an annual draw plus a mid-year retest and has a more polished consumer dashboard, while Superpower leads on entry price. Neither service prescribes or manages your care directly.

Can I get Function Health’s biomarker count without a membership?

Yes, but it takes assembly. Labcorp OnDemand and Quest Health let you order individual tests without a subscription. Building a panel that covers 80 to 100 biomarkers by cherry-picking individual tests typically costs $200 to $400 in a single visit depending on which markers you select. You will not get built-in trend tracking or physician interpretation, but the raw data quality is identical to any membership service since they all use the same reference labs.

Does Function Health use Quest or Labcorp for their draws?

Function Health uses Quest Diagnostics for most of their phlebotomy network in the US. This is worth knowing because it means the actual lab processing is identical whether you order through Function Health, Superpower, or Labcorp OnDemand. The differentiation between membership services is in the dashboard, physician review, and interpretation layer, not in the underlying lab chemistry.

Is InsideTracker better than Function Health?

InsideTracker is better than Function Health if you are a performance-focused athlete who wants biomarkers compared against sport-specific and age-matched peers. Function Health tests more biomarkers in total and, at $365/year, costs less than a year of InsideTracker’s Ultimate plan (about $489 with the membership). For general health baseline work with no athletic focus, Superpower offers more markers and clinician review at a lower price than either.

What is the best full body blood test alternative to Function Health?

For comprehensive full-body blood testing, Superpower covers the broadest range of clinically relevant biomarkers at the best price among alternatives. The 100+ biomarker panel spans metabolic, hormonal, cardiovascular, inflammatory, thyroid, and nutritional markers. 10x Health covers more if you add genetic testing, but at a dramatically higher price point that most users cannot justify for routine annual testing.

Do any Function Health alternatives accept HSA or FSA?

Most do. Superpower, InsideTracker, Labcorp OnDemand, Quest Health, and Everly Health all accept HSA and FSA payment. Marek Health also accepts HSA/FSA for lab work, though some of their clinical services may require itemized documentation for FSA reimbursement. Using pre-tax dollars effectively lowers the out-of-pocket cost by 22 to 37 percent depending on your tax bracket.

Are there alternatives to Function Health for people on Medicare?

Medicare Part B covers annual wellness visit labs ordered by your physician, including CBC, metabolic panel, lipids, and diabetes screening. Medicare does not cover direct-to-consumer membership services like Function Health, Superpower, or InsideTracker. If you want biomarkers beyond what Medicare covers and are willing to pay out of pocket, Labcorp OnDemand and Quest Health let you add tests without a subscription commitment, which is more flexible than committing to an annual membership when Medicare already covers the basics.

Is the best lab membership different from the best alternative to Function Health?

They overlap but are not identical. The best lab membership overall in 2026 for most adults is Superpower, which also happens to be the best Function Health alternative. But the best lab membership for a competitive athlete is InsideTracker, and the best for a man wanting hormone management is Marek Health. The category is maturing fast, and specialization is increasing.
