The Best Function Health Alternatives for 2026
The best alternative depends on what you want to change: the markers, the support after results, or the way you pay.
Jinfiniti Precision Medicine publishes this guide and is one of the seven options. Every company is assessed on the same criteria, from its own public information.

Why people look for Function Health alternatives
Function Health gives a broad annual screen at a low price, and for many people that is enough. Others want something the model does not offer.
More time with a clinician
Function Health gives a written clinician summary, and a provider calls about critical results. Some people want scheduled consults.
Different markers
Its published list does not include intracellular NAD+, Klotho or senescence markers.
An epigenetic age
Some people want DNA methylation clocks rather than a standard blood panel.
No membership
Some people prefer to pay per test, with no yearly renewal.
Where they live
Function Health does not serve Rhode Island, Hawaii or Puerto Rico, and prices differ in New York and New Jersey.
Every option sells longevity or biomarker testing direct to US consumers. We compared each on the same points: what it measures, collection, support after results, retesting, price and availability, using the company’s own website.

The alternatives, one by one
Same four questions for every company: who it suits, how it differs, what it does well, and where it falls short.
Superpower
Best for: A yearly membership like Function Health’s, with an AI assistant and a care team.
- How it differs
- The closest match to Function Health’s model: 150+ biomarkers a year across two blood draws, with add-on tests, peptides and prescriptions available.
- What it does well
- Similar breadth at a slightly lower yearly price, an action plan after every test, and 2,000+ Quest locations or an at-home draw.
- Limitation
- At-home blood draws cost extra, and pricing may differ in New York and New Jersey.
Lifeforce
Best for: An ongoing, clinician-led program, including hormone care and prescriptions.
- How it differs
- On the monthly plan, a phlebotomist comes to your home every 3 months to test 50+ biomarkers, and each draw is followed by a 45-minute telehealth consult.
- What it does well
- Regular clinician contact, health coaching and at-home collection as standard.
- Limitation
- A smaller panel (50+ biomarkers) and an ongoing monthly fee.
InsideTracker
Best for: Performance-minded people who want nutrition, exercise and supplement guidance from blood data.
- How it differs
- You pay per blood test (up to 48 biomarkers) plus an annual platform fee, and get an action plan, an AI guide and wearable sync.
- What it does well
- A detailed, adjustable action plan, and blood testing in the US and Canada.
- Limitation
- Biological age (InnerAge) costs extra, and no clinician consult is listed.
TruDiagnostic
Best for: Research-grade epigenetic aging clocks to track whether an intervention works.
- How it differs
- A DNA methylation test, not a standard blood panel. A finger-prick blood spot gives biological age, pace of aging (DunedinPACE) and ages for 11 organ systems.
- What it does well
- No lab visit, and a deep read of more than 1,000,000 methylation sites.
- Limitation
- No standard blood results, results take 3 to 4 weeks, and no consumer consult is listed.
NOVOS
Best for: Tracking your pace of aging over time, without a membership.
- How it differs
- One finger-prick sample gives biological age, pace of aging, organ ages and telomere length, in a 55-page report.
- What it does well
- A one-time purchase, a lower price for multiple kits, and a free AI longevity coach.
- Limitation
- No standard blood results, guidance comes from an AI coach rather than a clinician, and it ships to the US and Canada only.
Tally Health
Best for: A needle-free way to benchmark how you are aging.
- How it differs
- A cheek swab measures DNA methylation to estimate your epigenetic age.
- What it does well
- A painless at-home test. The membership adds action plans, a daily supplement and a retest every 6 months.
- Limitation
- No blood panel, results take 6 to 8 weeks, and no clinician consult is listed.

For people who want the cellular picture, and a plan
Jinfiniti’s model centers on measurements that mainstream panels rarely include. Intracellular NAD+ is a molecule your cells use to make energy and repair DNA. ROM and TAC show the balance between oxidative stress and your antioxidant defenses. Klotho is a protein linked to kidney function and healthy aging. Senescence markers track cells that have stopped dividing but still send out inflammatory signals.
Jinfiniti
Best for: Cellular markers that mainstream panels rarely include, and help turning results into a plan.
- How it differs
- Every core panel measures intracellular NAD+ and oxidative stress (ROM and TAC). The Ultimate Longevity Panel adds Klotho, senescence markers and inflammatory cytokines. Samples run in Jinfiniti’s own CLIA-certified lab.
- What it does well
- A free expert consultation with each panel, a protocol built from your results, and retesting to check the response.
- Limitation
- A higher price per test than the membership services, and each retest is a separate purchase. Results take 7 to 10 days. The panels leave out some standard screens on Function Health’s list, such as urinalysis, heavy metals and thyroid antibodies.

Questions about Function Health alternatives
Short answers to what people ask most.
What is the best alternative to Function Health?
It depends on what you want to change. Superpower is the closest like-for-like option. Lifeforce suits people who want regular clinician consults. Jinfiniti suits people who want cellular markers such as intracellular NAD+ and Klotho, with an expert consultation and a protocol. TruDiagnostic, NOVOS and Tally Health suit people who mainly want an epigenetic age test.
Which Function Health alternative offers more clinician support?
Of the options here, Lifeforce offers the most scheduled clinician time: on its monthly plan, each quarterly blood draw is followed by a 45-minute telehealth consult. Superpower offers a care team for one-on-one support. Jinfiniti includes a free expert consultation with each panel.
Which alternatives measure NAD+, Klotho, or cellular aging markers?
Of the companies on this page, only Jinfiniti publishes tests for intracellular NAD+, Klotho and senescence markers, as of September 29, 2026. If by cellular aging you mean epigenetic age, TruDiagnostic, NOVOS and Tally Health measure DNA methylation instead.
Is there a Function Health alternative without a membership?
Yes. Jinfiniti and NOVOS sell tests as one-time purchases. TruDiagnostic and Tally Health offer a single test or a subscription. InsideTracker charges per test plus an annual platform fee.
Which options support retesting over time?
All of them, on different schedules. Function Health and Superpower include two tests a year. Lifeforce retests every 3 months on its monthly plan. InsideTracker recommends every 3 to 6 months. Tally Health members retest every 6 months, and NOVOS suggests every 6 to 12 months. With Jinfiniti, you retest after you act, so you can see whether the plan worked.
How do the alternatives compare on total annual cost?
For one year, as of September 29, 2026: Function Health is $365 and Superpower is $349, each with two blood draws. InsideTracker is $489 for one test or $761 for two. TruDiagnostic is $998 for four tests on its subscription. NOVOS is $598 for two kits. Lifeforce is $599 on its Core Annual plan, or $1,449 a year on its full annual plan. Tally Health’s membership is $129 a month. One Jinfiniti Cellular Essentials Panel is $898. Prices change often, so check before you buy.
