Quick answer: The Function Health refund policy offers no money-back guarantee on its annual membership fee. Once you pay, that fee is non-refundable under standard terms. You can cancel future renewals at any time, but the membership year you already paid for is not returned. Lab draw fees and some add-on costs follow a separate policy, and the window to dispute a charge is narrow, so the financial risk sits entirely on the front end.

Does Function Health have a refund policy or money-back guarantee?

No, Function Health does not offer a money-back guarantee on its membership. The company treats the annual fee as payment for access to the platform and a scheduled panel of lab tests, not as a subscription you can trial and cancel for a full refund. This matters because the fee structure means you are committing roughly $499 to $549 (2026 pricing) to a full year upfront, and that sum is gone the moment the payment clears. See the full breakdown of what you pay in our function health cost breakdown.

Where the policy gets nuanced is with add-on tests and supplemental draws. If you purchase an optional add-on test and the specimen fails at the lab before analysis, Function Health will typically re-draw at no charge or issue a credit. That is not a refund in the consumer sense; it is a quality-of-service remedy. The distinction is important: you cannot decide two weeks in that the membership was not worth it and expect your $499 back.

Function Health has also offered a limited introductory rate (around $299 to $399) to early members and through certain promotional channels. Those discounted purchases carry the same no-refund terms, so the lower entry price does not come with extra flexibility on cancellation.

How to cancel your Function Health membership

Canceling Function Health prevents your annual membership from auto-renewing; it does not cut off access mid-year and it does not trigger any refund. The steps as of mid-2026 are:

  1. Log in to your Function Health account at functionhealth.com.
  2. Navigate to Account Settings, then Membership.
  3. Select Cancel Renewal (the wording may show as “Do not renew” or similar).
  4. Confirm the cancellation through the prompt. You should receive an email confirmation within a few minutes.
  5. If you do not see the option or receive no confirmation email, contact support at support@functionhealth.com directly and request cancellation in writing.

Keep that confirmation email. If a charge appears on your card at the next billing anniversary, the email is your documentation for a dispute with your credit card issuer. Disputes filed within 60 days of the charge are far more likely to succeed than those filed later.

One thing members get wrong: they assume that canceling through their bank or PayPal is equivalent to canceling with Function Health. It is not. Blocking a charge at the card level may work once, but it does not formally close your account, and the company may still consider your membership active. Always cancel through the platform itself first.

What happens to your membership after cancellation

After you cancel the renewal, you retain full access to your Function Health dashboard, your historical lab results, and any scheduled draws that fall within the membership year you already paid for. The account does not go dark the moment you hit cancel. You are simply opting out of the next billing cycle.

Practically speaking, if you paid in January and cancel in August, you still have access through December. Your results do not disappear after the membership ends, but platform features that require an active membership (like ordering new tests or accessing physician review for new draws) would become unavailable at expiration.

Function Health does not currently offer a pause or freeze option. If you want to stop paying but plan to return, your only option is to cancel and re-subscribe later, potentially at whatever the current rate is at that time. Early members locked in rates well below current pricing, so this is a real consideration for anyone on a grandfathered plan.

Is any part of the Function Health fee refundable?

In practice, almost nothing is refundable, but there are narrow exceptions worth knowing.

Charge type Refundable? Notes
Annual membership fee No Non-refundable under standard terms once paid
Add-on test (ordered but not yet drawn) Sometimes Contact support before the lab appointment; no guarantee
Add-on test (failed specimen / lab error) Yes (credit or re-draw) Quality remedy, not a consumer refund
Duplicate charge / billing error Yes Submit proof to support; standard 5 to 10 business day resolution
Charge after confirmed cancellation Yes (dispute eligible) Dispute with credit card issuer if support does not resolve in 72 hours
Promotional or gift membership No Same terms as standard membership

One scenario that does sometimes produce a partial remedy: if you joined and Function Health failed to schedule your blood draw within a reasonable window due to a coverage gap in your area, you may have grounds to request a credit. That is not published policy, but it has come up in member forums. The company expanded its phlebotomy network significantly through 2025 and into 2026, so coverage gaps are less common, but rural members still encounter them.

The real financial risk before you join

The no-refund structure shifts all the risk to the buyer. Here is what that means in dollars: if you pay $499, complete zero draws (because you moved, got sick, or simply did not follow through), you lose $499. There is no prorated refund, no credit toward a future service, and no consumer protection pathway unless there was a billing error or the company failed to deliver the promised service.

Compare that to walking into Quest Diagnostics or Labcorp for a la carte testing. A comprehensive metabolic panel costs roughly $15 to $60 cash-pay. A lipid panel runs $25 to $80. You pay per test, per draw, and you owe nothing if you reschedule. The Function Health annual model is a better deal if you actually complete both annual draws and use the physician review feature. It is a worse deal if you complete none.

The math improves significantly if you factor in what you actually get. Function Health bundles over 100 biomarkers per draw (two draws per year), physician review, and trend tracking. Replicating that a la carte at Quest would cost $800 to $2,000 depending on the test mix. So the value case is real, but it depends entirely on follow-through. Read our full function health review for a detailed look at whether the panel is worth the commitment.

One thing worth noting: HSA and FSA funds can be used to pay for Function Health membership, which means pre-tax dollars reduce the effective cost by your marginal tax rate. A $499 membership costs a person in the 22% bracket roughly $389 in after-tax dollars. That does not change the no-refund terms, but it changes the out-of-pocket pain if you do not follow through.

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 blood test review reviewed in full.

How Function Health cancellation terms compare to Superpower

Superpower, the closest direct competitor at roughly $199 per year, also does not offer a money-back guarantee on its membership fee. However, the lower price point changes the risk calculus substantially. You are committing $199, not $499, and the per-draw value of 100-plus biomarkers with physician review is arguably comparable on a cost-per-biomarker basis.

Cancellation on Superpower works similarly: cancel renewal through your account settings before the next billing date, keep your results after expiration, and do not expect a refund on the current year. The structural terms are nearly identical. The difference that matters to someone weighing the financial risk is the initial dollar commitment.

Policy point Function Health Superpower
Annual price (2026) ~$499 to $549 ~$199
Money-back guarantee No No
Cancel renewal anytime? Yes Yes
Access after cancellation? Through paid period Through paid period
Prorated refund? No No
HSA/FSA eligible? Yes Yes
Draws per year included 2 1

What people get wrong about the cancellation process

Four misconceptions come up repeatedly in member forums and support threads.

Misconception 1: Canceling stops your current membership. It does not. Cancellation stops auto-renewal. You keep access through the end of the period you paid for. Some members cancel expecting an immediate account freeze, then panic when they still see charges or active access. That is normal behavior, not a billing error.

Misconception 2: Downgrading or pausing is an option. As of mid-2026, Function Health has no published pause or downgrade tier. Some members have negotiated an extension or credit in cases of documented hardship (job loss, medical leave), but that is not a standard policy and is not guaranteed.

Misconception 3: Contacting your bank first is the fastest solution. Filing a chargeback before contacting Function Health support typically violates terms of service and may result in account closure without any further access to your historical lab data. Always exhaust the internal support route first (email, 48-hour response window is typical). Only escalate to a bank dispute if support fails to resolve a legitimate billing error within a week.

Misconception 4: The trial or waitlist period included a trial refund window. Function Health ran a waitlist model for its first two years where members paid at signup but waited months for a slot. Some members assumed that waiting period was a trial. It was not. Payment was collected upfront and the no-refund terms applied from the moment of purchase, regardless of how long the wait was.

If you regret joining: practical options short of a refund

You paid, you cannot get the money back, but you have not had your blood drawn yet. Here is how to extract maximum value from a membership you are not sure about.

First, schedule both draws before you cancel the renewal. The annual membership includes two comprehensive draws. If you get both done, you have 200-plus data points on your biomarker baseline, which is genuinely useful health data regardless of what you decide about year two.

Second, use the physician review. This is the feature that most members underuse. Each draw includes a clinician review of results. A 20-minute conversation about your lipid subfractions or thyroid panel is worth something, even if you later decide the annual cost is not sustainable.

Third, export your data. Download your results as PDF before your membership lapses. Some of the biomarkers Function Health runs (like Lp(a), ApoB, fasting insulin) are not routinely ordered by primary care physicians. Having a baseline on paper, even years later, is clinically useful. Talk to a clinician about your results to understand the long-term significance.

Fourth, list your remaining membership access. Some members who cannot use a service mid-year have transferred access with Function Health’s knowledge, though this is not a published feature. If you are months into a membership you cannot use, it is worth asking support whether account transfer is possible.

FAQ

Can you cancel Function Health at any time?

Yes, you can cancel the auto-renewal at any time through your account settings. Canceling does not immediately terminate access; you keep all membership benefits through the end of the period you already paid for. There is no penalty or fee for canceling early.

Does Function Health offer a free trial?

No. Function Health does not offer a free trial. You pay the full annual fee at signup. There is no trial period, no trial draw, and no way to test the platform before committing financially.

Is Function Health refundable if I never got my blood drawn?

Generally no. The membership fee covers platform access and the right to schedule draws, not the draws themselves. Even if you never completed a blood draw, the standard terms do not entitle you to a refund. If you believe the company failed to provide the service as described (for example, no phlebotomy availability in your area for a sustained period), that is a stronger basis for requesting an exception, but it is not guaranteed.

How to cancel Function Health membership step by step?

Log into functionhealth.com, go to Account Settings, select Membership, then choose Cancel Renewal or Do Not Renew. Confirm the prompt and save the confirmation email you receive. If the option is not visible, email support@functionhealth.com with a written cancellation request before your renewal date.

What happens to my Function Health data if I cancel?

Your historical lab results remain accessible on the platform through the end of your paid period. After expiration, access to the dashboard may be limited or removed, depending on the account status. Download all PDFs of your results before your membership expires so you retain them regardless of what happens to your account.

Does Function Health charge a cancellation fee?

No. There is no fee to cancel your Function Health membership renewal. You simply stop the next annual billing cycle from occurring. The charge you already paid is not refunded, but nothing additional is deducted for canceling.

Can I dispute a Function Health charge with my bank?

You can dispute any charge with your card issuer, but it is strongest for billing errors (duplicate charge, charge after confirmed cancellation) rather than dissatisfaction with a service you agreed to purchase. If you dispute a valid charge and lose, you may also risk account closure. Exhaust internal support channels first. Disputes filed within 60 days of the statement date are most likely to succeed at the bank level.

Is Function Health a subscription that auto-renews?

Yes. Function Health is an annual subscription that auto-renews at the then-current price unless you cancel before the renewal date. The renewal charge will appear on the same payment method used at initial signup. Check your membership settings a few weeks before your anniversary date to avoid an unexpected charge.

Does Function Health offer any discounts to reduce the upfront risk?

Occasionally. Function Health has offered promotional pricing through physician referral programs, corporate wellness partnerships, and limited-time campaigns. These discounts do not change the refund terms, but a lower entry price reduces the financial exposure. There is no published referral discount openly available on the main site as of mid-2026, but employer benefit portals and some concierge medicine practices have negotiated group rates.
