Which costs less, Everlywell or Function Health?

Function Health, at $365 a year against $399 for Everlywell 360. Function's price includes two draws, and Everlywell 360's includes one test. Both are HSA/FSA eligible. Everlywell also sells single kits outright, so one specific test can cost far less than either membership.

Does Everlywell or Function Health test more biomarkers?

Function Health does. Its annual draw lists 116-118 biomarkers and its mid-year draw rechecks around 60 of them, for 160+ lab tests across two draws. Everlywell 360 publishes 83 biomarkers on one test, which rises to 87-88 when white blood cell percentages and absolute counts are listed separately.

Do Everlywell and Function Health track biological age?

Both do. Everlywell's WellScore is a number between 50 and 100 built on nine biomarkers and delivered with Everlywell 360 results. Function Health includes a Biological Age test in its membership and runs it twice a year, so the main difference is how often you get a reading.

How quickly do Everlywell and Function Health deliver results?

Function Health's first results typically arrive within 48 hours of testing, though reviewers report three to four weeks for its clinician-reviewed plan. Everlywell 360 results usually take up to 9 days after lab work, and the Care Plan follows within 24 hours of results.

Can you see a clinician with Everlywell or Function Health?

Everlywell sells a 360 + Consult tier that adds a 1:1 meeting with a licensed provider, who can prescribe when medically appropriate. Function Health's clinicians review your results and your health history to build the analysis and action plan that comes with the membership.

Are Everlywell and Function Health HSA/FSA eligible?

Yes. Both memberships are eligible, though Everlywell's own-brand supplements are listed as ineligible. Insurance cannot pay for Everlywell 360. Reimbursement rules vary by plan, so confirm details with your plan administrator before you buy.

Everlywell vs Function Health: Features & Pricing (2026)

Key takeaway:

Everlywell 360 ($399/yr) is a lab testing membership built around one 83-biomarker test a year, a WellScore, and a clinician-reviewed Care Plan. Function Health ($365/yr) is a biomarker testing company that runs two draws a year, with a Biological Age test and a clinician-reviewed action plan. If you want somewhere to act on your results after the plan arrives, Superpower ($199/yr) goes beyond biomarker testing to be a true home for health. Alongside one draw of 100+ biomarkers, it adds direct wearable integration and a marketplace for supplements and compounded prescriptions (like peptides), with Superpower AI keeping the plan current.

What is Everlywell, and what is Function Health?

Everlywell sells a catalog of single tests and at-home kits, and its annual membership, Everlywell 360, is a lab-draw panel. One visit produces a full panel, a WellScore, and a Care Plan that a clinician has reviewed.

Function Health is a biomarker testing membership that schedules two lab draws a year, with clinicians reading your results against your health history.

Both end in a clinician-reviewed plan. They split on how many draws a year buys, and on how often your biological age gets measured.

What does Everlywell include?

A $399 Everlywell 360 membership covers one lab test, a biological age score, and a clinician-reviewed Care Plan. Fees at the lab are part of the purchase, and a 1:1 consult is sold on a higher tier.

Everlywell's own three-step process runs like this:

Schedule lab tests — Pick a lab draw site and book a collection time.
Review your results — See your numbers in a dashboard, with clinicians analyzing them.
Take action — Follow the Care Plan, or add a consult to talk through the results.

The visit works as a standard lab draw. Blood comes from a vein in your arm, you collect a urine sample yourself, and the knowledge base asks for a 9 to 12 hour fast. The consult tier, called 360 + Consult, brings a licensed provider who can prescribe when medically appropriate.

What does Function Health include?

Function Health members pay $365 for two draws, a results dashboard, and an analysis and action plan written by clinicians.

Function describes four steps from sign-up to follow-through:

Schedule tests — Share your health history, then book the first draw.
Get insights — Clinicians use that history to pick out the results that matter and the next moves.
Take action — Test again every 3 to 6 months, because Function sees health as a trend.
Monitor for life — Your results accumulate so patterns show up early.

Supplement advice comes through SuppCo, which became part of Function to tie your supplement routine to your biomarker data. Function lists no prescription access.

How do Everlywell's WellScore and Function's Biological Age test differ?

Everlywell hands you one aging score a year; Function Health reruns its biological age test in the middle of the year.

Everlywell's WellScore is a single number between 50 and 100, built from nine biomarkers and exclusive to Everlywell 360. It arrives with your results.

Function's Biological Age test is included in the membership and tested twice a year. Like the WellScore, it rests on phenotypic age.

The score itself is similar in kind. What changes is how many readings you get before the year ends: one at Everlywell, two at Function.

What biomarkers do Everlywell and Function Health measure in 2026?

Everlywell 360 publishes 83 biomarkers, and Function Health publishes 160+ lab tests across two draws.

Everlywell counts each white blood cell type once, though the panel reports a percentage and an absolute count for each. Everlywell does not label calculated markers, so the split below applies the same rule used for Function's list. Both columns include urinalysis.

	Everlywell 360	Function Health
Initial draw	87-88 biomarkers (78-80 distinct and 8-9 calculated)	116-118 biomarkers (102-103 distinct and 14-15 calculated)
Follow-up draw	None, Everlywell 360 runs once a year	Retests ~60 markers already on the annual panel, included
Headline count	83 biomarkers on one test	160+ lab tests across two draws

Function's annual draw is the longer panel, and its mid-year draw adds a recheck on top. Everlywell's list stops at one visit.

Function's add-ons include:

Heart, thyroid, and autoimmunity — Extended panels for the heart, metabolism, and thyroid, plus celiac and genetic heart risk tests.
Hormones, toxins, and cancer — Extended hormone health, heavy metals, PFAS, the GRAIL cancer test, and Alzheimer's detection.
Scans — Heart CT, lung CT, and MRI through Ezra.

Everlywell sells its single tests without a membership:

Cancer screening — Clairity Breast, the Galleri multi-cancer test, Caris Detect, and FIT colon screening.
Gut and food — Jona gut microbiome, food sensitivity, and celiac screening.
Sexual and hormone health — At-home and in-person STD panels, plus women's health, men's health, and testosterone tests.

What are the official 2026 membership prices for Everlywell and Function Health?

Everlywell 360 costs $399 a year, billed annually. Function Health costs $365 a year, which it markets as a dollar a day.

Extras sit outside both prices. Everlywell says additional labs and prescriptions are not included in the membership fee. At-home draws at Function cost a variable fee and exist only in select areas. In New York and New Jersey, Function collects an added fee at the facility on the day of the draw.

Everlywell also runs a second product, Everlywell+, at $39 a month, a separate plan from the annual membership. Both 360 and Function memberships are HSA/FSA eligible.

How fast do results and plans arrive?

Function Health delivers numbers sooner, and Everlywell delivers an interpretation sooner after those numbers.

Function says the first batch of results typically arrives within 48 hours of testing. It publishes no timeline for the clinician-reviewed plan, and reviewers report waits of three to four weeks.

Everlywell returns most 360 results within 9 days of lab work, and the Care Plan follows within 24 hours of the results.

Who is Everlywell best for, and who is Function Health best for?

Everlywell is best for:

People who want a single annual lab visit with a clinician-reviewed Care Plan.
People who want the option of a 1:1 consult that can lead to a prescription.
People who want to buy single kits, such as STD or food sensitivity tests, without a membership.

Function Health is best for:

People who want two scheduled draws and a biological age reading twice a year.
People who would rather see numbers within 2 days of the draw than wait for a plan.
People who want a longer annual panel at a lower membership price than Everlywell 360.

The bottom line

Everlywell 360 and Function Health both turn one payment into lab results and a plan a clinician has reviewed. Everlywell keeps it to a single annual test, with a Care Plan that follows within a day of results. Function Health spreads the year across two draws, rereads your biological age midyear, and returns its first numbers within 48 hours.

Both stop at the plan. Neither membership fee includes prescriptions. Everlywell sells its own vitamins, and Function offers supplement guidance through SuppCo.

Superpower costs $199 a year in most states, the lowest price of the three, against Function's $365 and Everlywell 360's $399. Function draws twice and lists 160+ lab tests, more than Superpower's 100+ biomarkers in one draw, so what Superpower adds is the follow-through. Superpower AI builds your Superpower Protocol from 100+ biomarkers from one draw, wearable data, and medical records. AI and care team support helps once results are in.
