Quick answer: If you are wondering how much is Function Health membership, the answer is $499 per year as of 2026, billed annually with no monthly option. That fee covers two full blood draw panels per year, each measuring 100 or more biomarkers, plus a physician-reviewed results dashboard. There are no per-test surcharges within the included panel, but some add-on tests and the $99 referral gift credit system carry separate fees. For comparison, the competing Superpower membership runs about $199 per year for a similar 100-plus biomarker panel with doctor review included.
What Is the Exact Function Health Membership Price?
The standard Function Health membership price is $499 per year, and that is the only billing cadence the company offers. There is no month-to-month option, no quarterly plan, and no free tier. You pay once, get access for 12 months, and the membership auto-renews unless you cancel before the renewal date.
A founding-member rate of $299 per year was available during Function’s early waitlist phase, and some users grandfathered into that price still hold it. New signups in 2026 pay $499. If you see $299 quoted anywhere online, verify when that article was written, because that rate has not been publicly available for new members since late 2023.
There is also a waitlist dynamic worth knowing. Function has historically required prospective members to request an invitation rather than sign up immediately. Waitlist length varies; during high-demand periods it has stretched to several weeks. The price does not change based on waitlist position.

What Does the $499 Annual Fee Actually Include?
The membership fee covers two complete blood draw sessions per year, typically spaced six months apart. Each session tests 100 or more biomarkers from a single venous blood draw at a Quest Diagnostics or Labcorp patient service center. Function negotiates bulk lab rates directly with those networks, which is how they justify the flat-fee model.
Specifically included in the base membership:
- Two annual panels of 100-plus biomarkers, covering metabolic health, thyroid, sex hormones, inflammatory markers, complete blood count, lipid fractions, vitamins, heavy metals, and organ function markers.
- Physician-reviewed results: a licensed physician reviews your panel and flags anything outside optimal range, not just the lab reference range. This distinction matters. Lab reference ranges are built from averages of whoever got tested at that lab, which often skews sick. Function uses tighter functional ranges.
- Longitudinal tracking dashboard: every result is stored and graphed over time so you can see a biomarker trend across multiple draws.
- Unlimited messaging with the care team to ask follow-up questions about results, though this does not substitute for a clinical visit or formal diagnosis.
- Lab order and scheduling support: Function sends the order directly to Quest or Labcorp, so you show up with a barcode and skip the insurance authorization dance.
What is explicitly not included: prescription authority, formal diagnosis, specialist referrals, or any in-person clinical services. Function is a lab membership, not a primary care practice.
Are There Hidden Costs or Add-On Fees?
The base $499 covers the two standard panels, but Function does offer optional add-on tests that cost extra. These are tests outside the core 100-plus biomarker set, usually more specialized or expensive assays.
Common Add-On Tests and Approximate Prices
| Add-On Test | Approximate Cash Price | Why You Might Add It |
|---|---|---|
| Apolipoprotein B (ApoB) standalone | $25 to $45 | Included in some panels; confirm before ordering |
| Omega-3 index (red blood cell) | $70 to $110 | Not a standard lab test at most draw sites |
| Cortisol (4-point saliva) | $90 to $140 | Saliva, not serum, requires separate kit |
| Continuous glucose monitor (CGM) add-on | $99 to $149 per sensor | Optional wearable integration, not a blood draw |
| Advanced cardiovascular (Lp(a), sdLDL) | $40 to $80 | Deeper lipid fractionation |
The precise price for any add-on test depends on which lab processes it and regional rate variation. Function displays add-on pricing in the member portal before you confirm, so you are not surprised at checkout. That said, those costs are not trivial if you stack several add-ons across both draws in a year.
One cost people overlook: the referral gift credit. Function allows members to gift a trial or discount to a friend, often framed as a free introductory draw. The mechanics of that program and whether there is a cost to the gifter vary; check the current terms in your member portal. For context, our function health gift membership article explains how the gifting program works in practice.
Does Insurance Cover Function Health?
No. Function Health does not accept insurance, and the membership fee is not reimbursable through standard commercial insurance plans. The company operates on a direct-pay model specifically to avoid insurance contracting. The upside is that you do not need a physician referral or pre-authorization. The downside is that you are paying entirely out of pocket.
HSA and FSA eligibility: This is where it gets complicated. The annual membership fee itself is generally not an eligible HSA or FSA expense because it functions more like a wellness subscription than a diagnostic service ordered for a specific medical condition. However, if your physician orders Function testing as part of a documented treatment plan, the rules can shift. Some members have successfully submitted Function costs for HSA reimbursement with a letter of medical necessity from their doctor; others have been denied. The IRS rules here are genuinely ambiguous, and your HSA administrator has the final word, not Function Health, and not us.

Function Health vs. Superpower: Which Costs Less Per Biomarker?
The most direct competitor in the direct-pay lab membership space is Superpower, and the price difference is substantial: Superpower runs about $199 per year versus Function’s $499.
| Feature | Function Health | Superpower |
|---|---|---|
| Annual price | $499 | ~$199 |
| Draws per year | 2 | 2 |
| Biomarker count | 100+ | 100+ |
| Physician review included | Yes | Yes |
| Longitudinal tracking | Yes | Yes |
| Draw network | Quest / Labcorp | Quest / Labcorp |
| Insurance accepted | No | No |
| HSA/FSA eligibility | Ambiguous | Ambiguous |
| Waitlist required | Sometimes | No |
| Cost per biomarker per year | ~$2.50 (at 100 markers x2) | ~$1.00 (at 100 markers x2) |
On pure cost-per-biomarker math, Superpower is roughly 2.5 times cheaper for a comparable panel. The panels overlap heavily. Both test thyroid (TSH, free T3, free T4), complete metabolic panel, lipids including LDL particle quality, CBC, hormones, inflammatory markers like hs-CRP and homocysteine, and key vitamins including D and B12. The main differences are in presentation: Function has a more polished dashboard interface and a clinical brand that some users associate with Dr. Mark Hyman’s involvement as a co-founder. That brand value does not translate to more lab tests.
The $300 annual price gap compounds quickly. Over three years, you pay $1,497 for Function versus $597 for Superpower, a $900 difference for panels that pull nearly identical biomarkers. For most people spending their own money, the Superpower math is hard to ignore. Read the superpower blood test review to see the full panel list side by side.
The simplest way to actually get this done
Superpower is a full-body lab membership that runs 100+ biomarkers, has each result reviewed by a doctor, and tracks your numbers year over year (about $199/year). It is what we point readers to when they would rather get one clean, complete draw than chase single tests one at a time. Here is superpower reviewed in full.
Is the Function Health Cost Justified Compared to a La Carte Testing?
This is the real question for anyone weighing a Function Health membership. If you ordered these 100-plus tests individually through your primary care doctor and they were covered by insurance, your out-of-pocket would depend entirely on your plan. For the uninsured, ordering comparable tests a la carte at cash-pay labs like Walk-In Lab, Any Lab Test Now, or directly through Quest’s cash-pay portal would cost roughly $800 to $1,500 for a panel of equivalent breadth.
That makes Function’s $499 genuinely cheaper than assembling the panel yourself from scratch at cash-pay rates. The catch is that most people with insurance already get a subset of these tests (basic metabolic panel, CBC, TSH, lipid panel) through annual physicals, and those are usually covered at low or zero cost-sharing. Function’s value proposition is strongest for:
- People whose insurance-covered annual labs are too narrow (basic metabolic panel only, no hormones, no inflammatory markers, no vitamins).
- People between jobs or without employer coverage who would otherwise pay full cash rates for lab work.
- Individuals who see a concierge or direct primary care physician who does not have lab ordering privileges in major networks.
- Health-optimization consumers who want longitudinal tracking in a single dashboard rather than paper printouts from a hospital system.
If your PCP already orders a comprehensive panel covered by your insurance, the $499 Function membership may not add much diagnostic value. You would be paying for the dashboard interface and the functional medicine interpretation lens.
How Does Function Health Billing Work?
Function Health charges the full $499 at sign-up. There is no payment plan or installment option. The membership auto-renews annually, and Function sends a reminder email before the charge processes. To cancel before renewal, you need to do so through the member portal; the cancellation process is covered in detail in our function health cost guide, which also walks through the refund policy.
Credit card surcharges do not apply. Function accepts major credit cards and debit cards. Some members have used HSA debit cards at checkout; the charge goes through, but whether it is a valid HSA expense is a tax question your administrator decides retroactively, not a Function policy question.
For those with Chase Sapphire Reserve or similar premium travel cards, Function Health has at times been listed in the annual lifestyle/wellness credit program. The terms of those card credits change year to year, so verify directly with your card issuer before banking on it covering part of the fee.
What Do You Pay Per Draw Under a Function Membership?
With two draws included in the $499 annual fee, the effective cost per draw is about $249.50. That compares favorably to single comprehensive cash-pay panels at Quest or Labcorp, which run $150 to $400 depending on how many markers you include. The caveat is that you have to use both draws to get that per-draw value; members who only use one panel in a year are effectively paying $499 for a single draw, which is expensive relative to alternatives.
The practical answer: schedule your first draw within 60 days of joining and your second draw roughly six months later. Do not let the second draw lapse because the membership year reset will not refund unused draws.
Can You Gift a Function Health Membership and What Does It Cost?
Function Health offers a gift membership option. The gifted membership is typically priced similarly to the standard membership, around $499, though Function has run promotional gift pricing at lower rates during specific windows. The gift recipient gets the same full membership experience. The gifter pays at checkout; the recipient activates using a redemption link.
Gift memberships do not stack with a recipient’s existing membership for extra draws. If someone already has an active Function membership and you send them a gift, the activation extends their membership period rather than adding extra panels within the same year. For the complete mechanics, see function health gift membership.
FAQ
How much is a Function Health membership in 2026?
The standard price is $499 per year. There is no monthly plan. The founding-member rate of $299 was discontinued for new signups and is only held by early members who locked it in before 2024.
What does the Function Health membership include?
Two complete blood draw sessions per year, each covering 100-plus biomarkers, plus physician-reviewed results, a longitudinal tracking dashboard, and unlimited messaging with the care team. Add-on tests beyond the core panel cost extra.
Is Function Health worth the cost?
That depends on your insurance situation. For people paying cash who want broad biomarker tracking, $499 is cheaper than assembling a comparable panel a la carte at cash-pay labs. For people with insurance that covers comprehensive annual labs, it is harder to justify. The main value beyond the tests is the functional medicine interpretation and the tracking dashboard.
How does Function Health membership cost compare to Superpower?
Superpower charges about $199 per year for a comparable 100-plus biomarker panel with physician review. That is $300 less per year, or $900 over three years, for testing that covers very similar marker categories. The core difference is brand positioning and dashboard design, not meaningful differences in which tests you get.
Can you use FSA or HSA money to pay for Function Health?
The membership fee is in a gray zone for HSA and FSA eligibility. It does not qualify as a traditional medical expense under IRS rules unless you have a letter of medical necessity from a physician. Some HSA administrators approve it; others deny it. If you plan to use HSA funds, get a letter of medical necessity from your doctor and check with your HSA plan administrator before submitting.
Does Function Health cost less with a referral code?
Function Health has at various times offered referral discounts, but these change and are not guaranteed. Any referral savings would apply at sign-up; there is no ongoing discount for being referred. Check the current sign-up page for active promotions, and ignore any third-party coupon sites claiming specific dollar amounts, since those are typically outdated or fabricated.
What happens if you only use one of the two draws?
Unused draws do not roll over to the next membership year. If you only use one of the two included panels, the second draw expires at your renewal date. There is no partial refund for unused draws, so planning your draw schedule in advance matters.
Is there a free trial for Function Health?
There is no free trial. The $499 annual fee is due at sign-up. Function has offered waitlist incentives in the past, but a no-cost trial of the full membership is not part of the standard offering. Some users have accessed a single panel through a gifted trial from an existing member, which is the closest thing to a trial experience the company offers.
How much does Function Health cost for a second family member?
Each member needs a separate membership at the full price. There is no family plan or household discount. Two adults in the same household would pay $998 per year combined. At that price, evaluating whether a competing service with a lower per-person cost makes more sense for the household is worth the time.
What is the cancellation and refund policy for Function Health?
Function Health memberships can be cancelled through the member portal before the renewal date to stop future charges. Refund eligibility after the annual fee processes depends on whether you have used any draws. The general policy is that used services are non-refundable. For the exact current terms, see the function health cost page, which tracks policy updates.
