Opt Health Vs Function Health — The Full Comparison

Opt Health and Function Health both sell an annual membership built around a blood panel, and that is roughly where the overlap ends. Function Health runs 100+ biomarkers twice a year at partner labs and returns commentary on a dashboard. Opt Health runs a 55+ marker panel every 3–4 months, attaches a one-on-one physician consult, and prescribes from the results. One product ends at interpretation. The other begins there.

What each platform actually is

Opt Health

Opt Health sells a cash-pay membership at roughly $3,000 a year, aimed at adults over 40. The clinical side is run by physicians, and a one-on-one consult is inside the base price rather than sold per session. What you physically get is a 55+ marker panel covering hormones, metabolic markers, inflammation, and nutrients, drawn by an at-home phlebotomist in most markets, then a written protocol that can include testosterone replacement, peptides, GLP-1 medications, or a supplement stack. Labs are re-run every 3–4 months and the protocol is adjusted against them. Opt Health does not bill insurance, does not operate in-person clinics, does not offer imaging, and does not include the cost of any medication it prescribes.

Function Health

Function Health sells a $499 annual membership that launched in 2023 with Kevin Rose and Dr. Mark Hyman on the founder page. The clinical side is clinician-written commentary attached to results rather than a named doctor you meet. What you physically get is two draws a year at a Quest or LabCorp partner site covering 100+ biomarkers across heart, metabolic, thyroid, immune, nutrient, hormone, kidney, liver, blood count, and heavy metal categories, plus a full PDF and CSV export of the raw values. Function Health does not prescribe, does not manage a protocol, does not bill insurance, and does not include imaging. Live physician time is a separate $150–$300 purchase.

Side by side on the standard rubric

The same nine criteria applied to both platforms, with the values each one publishes.

What each actually costs

Opt Health has no stated one-time onboarding fee, so year two starts from the same ~$3,000 membership as year one. The variance sits entirely in medication. A member on a compounded GLP-1 at $200–$400 a month is carrying $2,400–$4,800 of annual drug cost on top of the membership; a member whose protocol is supplements and a sleep intervention may add almost nothing. That is why the realistic year-one range is quoted as $3,000–$6,000 and not a single figure. Year two moves in the same direction as the protocol: if a GLP-1 course ends, the ongoing number drops back toward the membership line.

Function Health also has no stated one-time onboarding fee, so its year two likewise restarts at $499. The realistic $750–$1,200 year-one figure assumes one add-on panel and one consult. Those are optional, and repeat buyers often skip the panel they already ran, which is the one case where year two lands under year one. The cost most people miss is geographic: if no Quest or LabCorp partner site is near your ZIP, a draw at a non-partner location adds $30–$80, twice a year. Nothing in Function Health pricing covers a medication, because Function Health does not write one.

Where Opt Health leads

• Physician time in the base price. A one-on-one consult with a physician is part of the membership rather than a $150–$300 line item.
• Prescription pathway. TRT, peptides, GLP-1 medications, and supplement protocols are written from your own lab values inside the same relationship.
• Retest frequency. Labs re-run every 3–4 months against Function Health's two included draws a year, which is the cadence dose adjustment needs.
• Draw logistics. At-home phlebotomy in most markets removes the trip to a partner lab and the ZIP-code dependency that goes with it.
• Between-visit access. A care team is reachable in the app for day-to-day questions rather than only at scheduled points in the year.

Where Function Health leads

• Panel breadth. 100+ biomarkers in the base membership against Opt Health's 55+. More organ systems are covered in a single draw.
• Entry price. $499 for the year is the lower barrier by a wide margin, and it is the whole obligation if you buy no add-ons.
• Raw data export. Results download as PDF and CSV in full, so the values move with you to any clinician or spreadsheet you like.
• A la carte depth. Advanced heart, cancer screening, hormone deep-dives, and food sensitivity panels are available at $100–$400 each when a specific question comes up.
• No ongoing commitment. One year of membership produces a usable snapshot, and nothing about the product assumes you return.

Trade-offs to weigh

Opt Health trade-offs

• The membership is the smaller half of the bill. Quoted year-one spend runs to $6,000 and above once TRT, GLP-1, or peptide costs are added, so ~$3,000 is a floor rather than a total.
• Narrower panel. 55+ markers skips coverage that a 100+ panel includes, and the physician is reading a curated set rather than a wide sweep.
• Telehealth only. There is no in-person clinic and no imaging, so anything requiring a physical exam or a scan goes to a provider outside the membership.
• The prescriber leaves with the membership. Canceling mid-protocol ends the relationship that is writing the prescriptions, which matters most for anyone titrating testosterone or a GLP-1.

Function Health trade-offs

• No prescriber. An out-of-range result produces commentary and a recommendation to see a physician; sourcing that physician and paying for them is on you.
• Two draws a year is a slow feedback loop. With a 7–14 day turnaround and six months between panels, you cannot use the included testing to check whether a dose change worked.
• The $499 headline understates typical spend. Most users land at $750–$1,200 once one panel and one consult are added, and heavy add-on use passes $1,500.
• Draw depends on your ZIP. Testing runs through Quest and LabCorp sites, and a non-partner location adds $30–$80 per draw.

Who should pick each

Pick Opt Health if: you are over 40, something concrete is wrong — energy, sleep, weight, or hormone symptoms — and you want a physician who will prescribe against your labs rather than hand them back. You are comfortable with roughly $3,000 before medication, you want reassessment every 3–4 months, and you would rather one relationship handled it all than assemble a testing service, a cash-pay doctor, and a pharmacy yourself.

Pick Function Health if: you are asymptomatic or already under a clinician's care, and what you want is the widest possible view of your biochemistry for the least money. You will read the results yourself or hand them to a doctor you already have, you do not expect to need a prescription from this purchase, and you value owning a downloadable data set more than owning a treatment plan.

Who should pick neither

Both platforms are cash-pay products for people who want more than a standard annual physical. If a specific, diagnosable problem is driving you, the cheaper and faster route is usually a clinician who can order the relevant test through insurance. These are the situations where a third option fits better.

• An in-network primary care workup. Persistent fatigue, unexplained weight change, or a family cardiac history can be worked up on insurance, and a covered CBC, CMP, thyroid panel, and lipid panel answer a lot for a copay.
• A specialist referral. Suspected thyroid disease belongs with an endocrinologist and a strong family history of early heart disease belongs with a preventive cardiologist. Neither platform replaces that.
• Hone Health — if testosterone is the only question, a hormone-focused telehealth program costs less than a full optimization membership.
• Lifeforce and Superpower — the mid-tier clinician-led option and the other $499 broad-panel option, listed alphabetically.

Can you use both?

Stacking works mechanically and costs about $3,500 a year before medication and add-ons. The usual pattern is one Function Health panel for breadth, then an Opt Health membership for the treatment loop. The problem is duplication: both memberships include a blood draw, both cover hormones, metabolic markers, inflammation, and nutrients, and you are paying twice for the overlapping portion. The 55+ marker Opt Health panel is not a subset of Function Health's 100+ list in every category, but the shared coverage is large enough that a second annual membership rarely earns its price on data alone.

The defensible version is sequential rather than simultaneous. Buy one Function Health year first for the wide sweep, including the organ systems an optimization panel does not prioritize, then let it lapse and move to Opt Health with those results in hand. That gives the physician a broader starting picture than the 55+ panel alone, costs $499 once rather than annually, and avoids a second draw covering ground you already have. Running both indefinitely only makes sense if you want an annual wide-net screen that your treatment panel genuinely does not include.

What the rubric does not capture

Nine rows cannot show who you actually talk to. At Function Health the interpretation is written, arrives with the results, and is the same document for every member with that value; there is no person on the other end unless you buy a consult. At Opt Health the interpretation happens in a scheduled conversation with a physician who has your history in front of them. The difference is not accuracy — a flagged hsCRP is a flagged hsCRP either way — it is who carries the next step. On one platform that person is you.

Speed of change is the second invisible column. Function Health's included cadence is two draws a year, so the fastest you can confirm that an intervention moved a marker is roughly six months, and only if the timing lines up. Opt Health's 3–4 month reassessment exists specifically so a dose can be adjusted against fresh values. If nothing about your protocol is changing, the slower cadence costs you nothing. If you are titrating anything, six-month feedback is not a feedback loop.

Month six feels different from month one on both, in opposite directions. Function Health is most valuable at the start, when a first full panel surfaces things you did not know; by month six there is nothing new until the next draw, and engagement drops to reading old numbers. Opt Health is least valuable at the start, when you have paid a full membership for one consult and one panel, and accrues value as the protocol gets adjusted. Judging either at the wrong point in the year produces the wrong answer about whether it was worth the money.
