Six services, one honest breakdown. Superpower, Function Health, InsideTracker, OneTwenty, Marek Health, and Ulta Lab Tests — what each costs, what you actually get, and who each one is right for.
The direct-to-consumer biomarker testing market has consolidated around a handful of meaningful options. The table below covers the six services worth considering in 2026 — organized by what they are and what they cost.
| Service | Price | Draws/yr | Biomarkers | ApoB | Lp(a) | Cancer mkrs | Rx access | Best for |
|---|---|---|---|---|---|---|---|---|
| Superpower | $199/yr | 1 | 100+ (150 w/ratios) | ✓ | Add-on | ✗ | ✗ | Entry-level longevity baseline |
| Function Health | $365/yr | 2 | 160+ | ✓ | ✓ | ✓ | ✗ | Comprehensive annual monitoring |
| InsideTracker | $149–$489/yr | 1–2 | Up to 48 | ✓ | Higher tiers | ✗ | ✗ | Athletic optimization + DNA |
| OneTwenty | $499/yr | 4 (quarterly) | 78 baseline + targeted | ✓ | Selected panels | ✗ | ✓ | Continuous care + coaching |

Superpower covers the longevity fundamentals — ApoB, full hormone panel (testosterone, estradiol, DHEA-S, SHBG), thyroid (TSH + free T3/T4), inflammatory markers (hsCRP, homocysteine), nutritional status (Vitamin D, B12, ferritin), and complete metabolic and CBC panels — at the lowest price in the market. The AI dashboard is polished, results come with plain-language explanations, and the biological age score gives you a concrete number to optimize toward. One honest caveat: some of the advertised “100+ biomarkers” include algorithmically derived ratios rather than direct measurements — the subject of a pending lawsuit filed by Function Health in January 2026. Lp(a) and omega-3 index require add-ons.
Function Health is the most thorough consumer biomarker service at a non-concierge price. Two annual draws, 160+ directly measured markers, cancer screening markers (PSA, CEA, AFP, CA-125), heavy metals (lead, mercury, arsenic), ANA autoimmune screen, and Lp(a) and omega-3 index included in the base panel. The twice-yearly cadence is the key differentiator — the only service in this price range that enables a test-intervene-retest loop within a single membership year. Trade-offs: no historical lab import, the AI protocol builder is newer than Superpower’s, and there is no home draw option. Founded by Dr. Mark Hyman and backed by $298M in Series B funding.
InsideTracker, founded in 2009 by researchers from MIT and Tufts University, was the original direct-to-consumer biomarker platform. Its differentiation today lies in DNA integration (genetic testing layered with blood data), wearable sync (Apple Watch and others), and a legacy of longevity science credibility. The marker breadth is narrower than Function or Superpower — up to 48 biomarkers on the Ultimate tier — but the action plan quality and InnerAge biological age calculation are well-regarded. Pricing is tiered and adds up quickly: the $149/year membership covers platform access only; actual testing runs $340–$489 additional depending on panel. Total annual cost for a serious user is $489–$638.
OneTwenty (formerly Outlive.bio) is the most integrated option in this comparison — less a pure testing service and more a continuous health optimization system. The $499/year Core membership includes quarterly biomarker testing (78 markers at baseline, then 20–40 targeted markers every 90 days), AI health coaching, wearable data integration (syncing continuous signals from Oura, Whoop, Apple Watch), and access to affiliated physicians who can prescribe when warranted. It is currently in beta, with full launch expected July 2026. The quarterly testing cadence is meaningful: it’s the only service that enables rapid intervention tracking. Trade-offs: newer platform with less track record, beta-stage product polish, and prescription access varies by state.
Marek Health is a different category from the services above — a telehealth clinical optimization practice, not a pure testing subscription. Founded by Derek from More Plates More Dates on the premise that you cannot optimize what you do not measure, Marek pairs comprehensive LabCorp panels with physician and health coach oversight and the ability to prescribe treatments (TRT, peptides, GLP-1s, thyroid, and more). Four panel tiers: Base ($250), Comprehensive ($450), Complete ($850), and Executive ($2,000). A key technical differentiator: Marek uses LC/MS (liquid chromatography-mass spectrometry) for testosterone and estradiol — significantly more accurate than standard immunoassays, particularly important for women and anyone on hormone therapy. Annual costs for a managed patient easily reach $1,000–$2,500 between panels and consultation fees. Right for someone who wants a clinician actively managing their optimization protocol. Not the right fit if you just want data.
Ulta Lab Tests is the direct-to-consumer ordering platform — not a subscription, not a curated panel, not an interpretation service. You choose exactly which markers to test, pay per marker or panel, and get results from Quest Diagnostics in 24–48 hours. A comprehensive longevity panel covering all the markers that matter — ApoB, Lp(a), fasting insulin, full hormone panel, thyroid, inflammatory markers, and nutritional status — runs $150–$300 depending on selection. The right choice if you want to test more than once per year, if you already know which specific markers you need, or if you want to verify results from another service. No dashboard, no biological age score, no protocol — raw results delivered to you. Use our AI tool to interpret them.
Superpower at $199/year is the right entry point for most people in this situation. It covers the markers that matter most for longevity — ApoB, full hormone panel, thyroid, inflammatory markers, nutritional status — at a price that makes it easy to commit. The biological age score and polished dashboard make results easy to act on. You can always upgrade to Function Health after you have a baseline and understand what you want to track more closely.
The twice-yearly draw is what separates Function from everything in its price range. If you’re working on a specific cardiovascular marker, adjusting hormone protocols, or supplementing based on deficiencies, the mid-year retest is the only way to know whether anything worked within a single year. Function also belongs at the top of the list for anyone who wants cancer marker screening or heavy metal testing as part of their annual workup.
OneTwenty is built around the idea that testing alone isn’t enough — what matters is continuous feedback and guided action. If you want quarterly testing, AI coaching that integrates your wearable data, and physician access for prescription optimization, OneTwenty is the most complete product in this space. The caveat is that it’s still in beta as of mid-2026, and newer platforms carry product maturity risk.
InsideTracker’s strengths are its athletic performance orientation, its DNA add-on (which layers genetic data with blood results for more personalized recommendations), and its wearable integrations. If you’re training seriously and want a platform built around performance optimization rather than longevity risk reduction, InsideTracker is the best fit. Be aware that the total annual cost including testing is $489–$638 — higher than the membership price alone suggests.
Marek Health is for someone who wants a physician actively involved in interpreting results and prescribing protocols — TRT, peptides, thyroid optimization, or GLP-1 weight management. The testing panels are excellent and the LC/MS hormone methodology is more accurate than what subscription services use. But the annual cost is substantially higher, and the model works best for someone already committed to an active optimization protocol.
If you already know which markers you want, if you need to test more than twice per year, or if you want to verify specific results from another service, Ulta Lab Tests is the right tool. There is no dashboard or interpretation layer — results come raw. Pair it with our AI biomarker interpreter to get longevity-optimal range analysis on whatever you order.
Most of these services are unavailable or priced differently in New York, New Jersey, and Rhode Island due to state regulations on direct-to-consumer lab testing. Superpower charges $399/year (vs. $199) in NY and NJ. Function Health, InsideTracker, and Ulta Lab Tests are generally not available in those states. Marek Health operates in 47 states. Confirm availability at each service’s website before purchasing.
