Is SiPhox Health at-home testing accurate?

SiPhox uses needle-free at-home capillary collection processed in a CLIA-certified lab, and it correlates well with standard testing for many markers, though capillary samples can be less precise for some, such as certain lipids. Superpower uses a standard venous blood draw.

Does Superpower cost less than SiPhox Health?

Not always. SiPhox can cost less at entry, with membership from $125 per testing period, while Superpower is $349 a year for 150+ health metrics plus a protocol, care, and prescription access. Your SiPhox total depends on how often you retest and which panels you add.

Does SiPhox Health include a care team or prescriptions?

No. SiPhox offers an AI assistant and optional paid coaching, with no included clinician care team and no prescription access. Superpower includes on-demand care-team access and prescription access, available through the marketplace when clinically appropriate.

Can I use an HSA/FSA for Superpower?

Yes. Both Superpower and SiPhox are HSA/FSA eligible, so you can put pre-tax funds toward your membership.

Is Superpower worth it?

The value is in acting on results, not just collecting them. Superpower reports that 60% of members said Superpower identified something previously missed or overlooked by a doctor. Messaging that care team is part of the membership rather than a coaching credit you buy per session.

Superpower vs SiPhox Health: Features & Pricing (2026)

Key takeaway:

SiPhox Health is a needle-free, at-home biomarker service: capillary collection with its EasyDraw device, membership from $125 per testing period, and flexible monthly, quarterly, or biannual retesting across a panel of 29 biomarkers on Longevity Essentials up to 59 on Ultimate 360. However, if you're looking for a fuller venous baseline with more post-testing actionable support, Superpower is $349/year and tests 150+ whole-body health metrics across an initial ~90 biomarker draw plus a built-in follow-up that retests ~60 of them, pairing a personalized action plan with on-demand care-team messaging between tests rather than a single scheduled appointment, and 36.3% of Superpower members reduced their biological age score between their first and second year.

What is Superpower, and what is SiPhox Health?

Superpower and SiPhox Health are both biomarker testing companies. A biomarker testing company offers blood-based testing on a periodic basis. Biomarkers are measurable signals in your blood, things like cholesterol, blood sugar, and hormones.

Some platforms stop at data and a report. Others turn results into a plan you can act on. Two questions separate them: how much do they measure, and what do they help you do next?

Superpower and SiPhox answer those differently. One is a full membership with care built in; the other is a convenient self-serve tracker whose cost scales with how often you test.

What does Superpower include?

Superpower includes a full annual membership, from an initial venous draw through on-demand care-team access. Superpower follows a simple path:

Join for $349 a year.
Give your initial venous blood draw at a lab, or at home for an added fee.
Receive ~90 health metrics in your dashboard.
Get a personalized action plan.
Give a built-in follow-up draw later, retesting ~60 biomarkers.
Message your care team on demand.

Both draws happen at any of 2,000+ partner locations across 40+ states, or at home for an added fee. Results arrive in your dashboard 5 to 10 business days after each one.

Among those results is a biological-age score, included in every membership. It's a single number for your whole body, so an optional OrganAge add-on breaks it into nine organ-level scores, across systems like metabolism, inflammation, liver, and kidney health, showing you which ones are pulling the total up or down.

You can shop a supplement marketplace with member-exclusive pricing, and prescriptions are available through the marketplace, when clinically appropriate, priced separately.

What does SiPhox Health include?

SiPhox Health includes an at-home kit with needle-free capillary collection, processed through a CLIA-certified lab. SiPhox is built for convenience. You order a kit, collect a sample at home with its needle-free EasyDraw upper-arm device, then mail it to a CLIA-certified lab. There's no vein draw and no lab visit, which is its genuine edge.

Results come back in 7 to 10 days, paired with AI-generated insights and supplement recommendations. Its broadest tier, Ultimate 360, runs 59 biomarkers, against 29 on Longevity Essentials, and you can retest monthly, quarterly, or every six months. Human coaching is an optional paid add-on, not an included care team.

What biomarkers do the Superpower and SiPhox Health memberships measure in 2026?

Superpower reports 150+ tests across two draws — ~90 from an initial venous draw, plus a built-in follow-up retesting ~60 of those markers — while SiPhox Health measures 29 biomarkers on Longevity Essentials up to 59 on Ultimate 360 per at-home capillary kit. The two count on different bases. Superpower's headline is a two-draw total; SiPhox's is the size of a single panel. In both, repeat testing re-runs markers already on the panel rather than adding new ones.

	Superpower	SiPhox Health
Counted from	Initial venous draw of ~90 biomarkers, plus a built-in follow-up that retests ~60 of those same markers	One at-home capillary kit: 29 biomarkers on Longevity Essentials up to 59 on Ultimate 360, with retests repeating that same panel
Accuracy vs. venous	Venous draw is the reference standard	Correlates well with venous methods for markers like HbA1c, glucose, and CRP, but research has found weaker correlation for some lipids

*Superpower's 150+ combines direct lab measurements with calculated metrics like LMR, MLR, and Ferritin:Albumin, spanning an initial draw and a built-in follow-up retest of the same markers. Both run through CLIA-certified labs.

What support and next steps do Superpower and SiPhox Health offer?

This is where the two diverge most. Superpower includes on-demand access to a care team you can message about your results, plus prescriptions are available through the marketplace, when clinically appropriate, priced separately, including TRT. A curated supplement marketplace offers member-exclusive pricing.

SiPhox works differently. It gives you AI-generated insights and supplement recommendations, with human coaching as a paid add-on. There's no included clinician care team, and no prescription access.

SiPhox hands you data and suggestions; Superpower keeps testing and action under one roof. 93% of members rated their Superpower Health Action Plan as more useful or even life-changing compared to their yearly checkup.

What are the official 2026 membership prices for Superpower and SiPhox Health?

SiPhox can cost less at entry, with membership starting at $125 per testing period for one of four core panels.

Superpower: $349/year, HSA/FSA eligible.
SiPhox Health: membership starts at $125 per testing period; pricing scales with cadence and panel choice — the broader Ultimate 360 panel adds $125, and a GLP monitoring panel adds $75; also HSA/FSA eligible.

Who is Superpower best for, and who is SiPhox Health best for?

The final word: does Superpower or SiPhox Health fit you?

SiPhox Health wins on entry convenience: needle-free at-home collection with flexible retesting, from $125 per testing period. If low-friction data tracking is all you want, it delivers.

But it stops there, at data and recommendations, and the needle-free format comes with a trade-off. SiPhox's broadest panel runs 59 biomarkers, against ~90 on Superpower's initial venous draw, and capillary samples correlate less well with venous methods for some lipids. Convenience answers what your numbers are; turning that into a next step is left to you.

Superpower: a fuller panel and built-in care vs. SiPhox's needle-free convenience

SiPhox Health's needle-free convenience leaves the next step up to you: track your numbers over time, then decide on your own what to do about a marker that moved or an insight its AI flagged. Superpower folds testing and action into one $349/year membership: ~90 health metrics from an initial venous draw, plus a built-in follow-up retesting ~60 of those same markers, 150+ tests across the two. Each round lands with a personalized action plan, and on-demand care-team messaging carries you between them. SiPhox's $125-per-testing-period model gives you the numbers and the recommendations, then leaves the deciding to you.

Starting with a full picture, not just a single data point, is the better place to begin a health journey. Start your Superpower blood test and see where your numbers actually stand.
