Function Health vs. Superpower vs. Jinfiniti

Function Health and Superpower look alike at first: a yearly membership, two blood draws and an app. The differences are in what each includes, what costs extra, and what happens after your results. Jinfiniti is here as a third model.

The short answer

Choose Function Health if

You want more included in the base price: Lp(a), homocysteine, thyroid antibodies, the omega-3 index and heavy metals are part of the 160+ tests, and first results arrive in about 48 hours.

Choose Superpower if

You want the lower price, an AI assistant and care team, and one app for add-on tests, supplements and prescriptions, and you are happy to pay for add-ons you need.

Consider Jinfiniti if

You want cellular markers neither publishes, such as intracellular NAD+, Klotho and senescence, with an expert consultation and a protocol built from your results.

Function Health vs. Superpower: the real differences

On price and draws, the two are close. These four points are where they part ways.

What the base price covers

Function Health includes Lp(a), homocysteine, thyroid antibodies, the omega-3 index, and lead and mercury. At Superpower, most of these are paid add-ons, and the omega-3 index is not listed.

Speed

Function Health says first results arrive in about 48 hours. Superpower says about a week.

Support after results

Function Health gives a clinician-written summary and protocols. Superpower gives an action plan, an AI assistant and a non-clinical care team of dietitians and coaches.

Add-ons and prescriptions

Superpower lists around 40 add-on tests with prices, plus a supplement marketplace and prescriptions through partner clinicians. Function Health offers MRI and CT at member prices.

What each costs over one year

Superpower’s base price is $16 lower. Add the tests Function Health already includes, and the gap can close quickly.

Function Health
$365/ year

Two lab visits, 160+ tests, clinician summary and protocols. Imaging extra.

Superpower
$349/ year

Two blood draws, action plan, AI and care team. Lp(a) $79, methylation panel $149, at-home draw $119.

Jinfiniti
$898/ panel

Cellular Essentials, with a free expert consultation. The Ultimate panel is $1,498.

Where Jinfiniti fits

If neither membership measures what you want to understand, Jinfiniti takes a different approach. It measures cellular markers that neither Function Health nor Superpower publishes, in its own CLIA-certified lab, and an expert reviews the results with you before you act.

The trade-off: Jinfiniti costs more per test, each retest is a separate purchase, and its panels leave out some standard screens, such as urinalysis, heavy metals and thyroid antibodies.

Questions about Function Health and Superpower

Short answers to what people ask most.

Function Health vs Superpower: which is better?

It depends on what you value. Function Health includes more in the base price, such as Lp(a), homocysteine, thyroid antibodies, the omega-3 index and heavy metals, and first results arrive in about 48 hours. Superpower costs a little less, adds an AI assistant and a care team, and puts add-on tests, supplements and prescriptions in one app. If you want cellular markers such as NAD+ or Klotho, neither publishes them; Jinfiniti does.

Which is cheaper, Function Health or Superpower?

As of September 29, 2026, Superpower is $349 a year and Function Health is $365 a year, and each includes two blood draws. Superpower’s lower price can change once you add tests that Function Health includes, such as Lp(a) ($79) or the methylation panel with homocysteine ($149). Superpower’s at-home draw is $119; Function Health’s at-home fee varies by location.

Does Function Health or Superpower test more biomarkers?

Function Health lists 160+ lab tests a year. Superpower lists 150+ biomarkers a year and says that total combines direct measurements with calculated values. The totals are close, so compare what is included for your goals instead of the headline number.

Do Function Health and Superpower both include Lp(a)?

Function Health includes Lp(a) in its membership. At Superpower, Lp(a) is a $79 add-on, as of September 29, 2026. Jinfiniti’s Cellular Essentials and Ultimate panels include Lp(a).

Which gives results faster?

Function Health says the first results arrive within about 48 hours of testing. Superpower says results take about a week. Jinfiniti results take 7 to 10 days.

Does Function Health or Superpower test NAD+ or Klotho?

No. As of September 29, 2026, neither published test list includes intracellular NAD+, Klotho or senescence markers. Superpower lists a marker called NADB, which measures exposure to 1,3-butadiene, not NAD+. Jinfiniti measures intracellular NAD+ on every core panel, and Klotho and senescence markers on the Ultimate panel.

Can I use HSA or FSA funds for Function Health or Superpower?

Both say their memberships are HSA and FSA eligible. Check with your plan, because eligibility depends on it.

Want the cellular picture, not only the standard panel?
