Quick answer: The Function Health cost is $365 per year, which buys 160+ biomarkers, two blood draws annually, a urinalysis, and a 6-month retest. That is genuinely thorough, and for clinically minded people it earns its price. But if your goal is a once-a-year full-body baseline you can actually track, Superpower covers 100+ biomarkers, 17 health scores, and an AI concierge for $199 per year, which is the better value for most people who just want a clear annual snapshot.

How Much Is Function Health? The Real Annual Number

Function Health pricing is refreshingly simple on the surface: $365 per year for the core membership. That is one flat annual fee, not a per-test charge, and it covers more than most people expect from a direct-to-consumer lab. So when people ask how much is Function Health, the honest one-line answer is $365 a year for the base plan, with the real total depending on the add-ons you choose.

For that $365 you get 160+ biomarkers, two blood draws per year, a urinalysis, and a built-in 6-month retest so you can see whether anything you changed actually moved the needle. The platform flags out-of-range results in plain language and gives you a clinician-reviewed report. On a pure marker count, that is one of the deepest panels in the consumer space.

The catch with how much Function Health costs is that the headline number is the floor, not the ceiling. The base membership is comprehensive, but the more specialized add-on tests (advanced cardiovascular markers, certain hormones, toxin and heavy-metal panels) sit outside the flat fee. None of that is hidden or dishonest, but it does mean your true first-year spend can climb past the $365 sticker if you bolt on extras.

What the $365 Function Health Membership Actually Includes

It helps to separate what is bundled from what is optional, because that distinction is where most of the confusion about Function Health cost comes from.

Bundled in the $365

Two draws a year is the standout. Most DTC services give you one annual snapshot; Function builds in a second draw plus a 6-month retest window, which is meaningfully better if you are treating your bloodwork like an ongoing project rather than a one-time photo. The 160+ marker panel and urinalysis are also part of the flat fee, along with the clinician-reviewed result summaries.

Not bundled (the add-ons)

Specialized panels are charged separately. If you came specifically for an advanced lipid breakdown, a deep hormone workup, or environmental-toxin testing, budget for that on top. This is normal for the category, but it is the part people forget when they compare a $365 membership to a $199 one. Always price the add-ons you personally need before deciding.

Bottom line on what you get: Function Health is more clinically thorough than most rivals, and the two-draws-plus-retest cadence is real value for anyone actively managing a metric. The AI chat layer exists but is newer and less mature than what some competitors now offer.

What Do the 160+ Function Health Biomarkers Actually Cover?

A marker count on its own tells you almost nothing, so it is worth knowing what that 160+ figure buys across the body. The point of a panel this wide is not to collect numbers, it is to see several systems at once so a value that looks fine alone can be read against the values around it.

Metabolic and blood sugar. Fasting glucose, HbA1c, and insulin, the trio that catches insulin resistance years before it reads as diabetes. Insulin in particular is one a standard physical usually skips, and it is often the earliest sign that metabolism is drifting.

Cardiovascular and lipids. Not just total cholesterol, but the breakdown into LDL, HDL, and triglycerides, plus advanced particle and inflammation markers on the deeper panels. This is the area where Function’s extra depth is most defensible, because heart risk hides in the detail the basic panel leaves out.

Thyroid and hormones. Beyond a lone TSH, the actual thyroid hormones, and a sex-hormone read that shifts with age and drives energy, mood, libido, and body composition. These are the markers people most often add on for.

Inflammation, nutrients, and organ function. High-sensitivity CRP for quiet systemic inflammation, vitamin D, B12, folate, iron and ferritin for the deficiencies behind fatigue and low mood, and kidney, liver, and a full blood count for the organs doing the silent work. The urinalysis adds a kidney and metabolic cross-check most competitors do not bundle.

The reason breadth matters is context. A low ferritin means one thing on its own and another next to a high CRP. A normal glucose reads differently beside a rising insulin. That cross-read is exactly what a single-marker kit can never give you, and it is the real argument for paying for a wide panel rather than chasing one test at a time.

The True First-Year Function Health Cost (Worked Example)

Sticker prices lie a little in this category, so it is worth running an actual first-year number instead of trusting the headline. Take a fairly typical buyer: someone who signs up mainly for cardiovascular and hormone insight rather than just a generic panel.

Start with the $365 base membership. That alone covers the 160+ markers, the two draws, the urinalysis, and the 6-month retest, so a person who wants nothing more than the standard panel genuinely pays $365 and stops there. But the buyer above usually wants the advanced cardiac markers (the deeper particle and inflammation set that the base panel does not fully cover) plus a fuller hormone workup. Once you layer those specialty panels on, the all-in first-year figure commonly lands somewhere north of the sticker rather than on it.

The point is not that Function Health is overpriced. It is that the $365 you see in the ad is the entry fee for the core experience, and the moment your reason for testing is a specific concern (heart, hormones, toxins) you should price that concern, not the headline. Build your own number before you compare it to anything else. A baseline-only shopper and a deep-dive shopper are buying two different products at two different prices, even though both start at the same $365 line.

What Do the Function Health Add-Ons Actually Cost?

This is the part of Function Health pricing that trips people up, so let us be precise about the shape of it even without quoting a figure that changes over time. The base membership is a flat annual fee. The add-ons are priced individually, and they fall into a few predictable buckets.

• Advanced cardiovascular panels. The deeper particle-level and inflammation markers that go beyond the standard lipid read. If heart risk is your reason for testing, this is the add-on most likely to matter, and the one worth pricing first.
• Expanded hormone workups. Fuller sex-hormone, adrenal, or thyroid panels beyond the bundled baseline. Common for anyone managing energy, fertility, perimenopause, or a testosterone question.
• Toxin and heavy-metal testing. Environmental exposure panels that sit well outside a routine checkup. Useful for a specific concern, rarely needed for a general baseline.

None of this is hidden or deceptive. The catch is simply that the $365 you saw in the ad is the entry fee, and the moment your reason for testing is a specific concern rather than a generic snapshot, your true number is the base plus whichever panels answer that concern. The practical move is to write down the one or two questions you actually want answered, price only the add-ons that answer them, and ignore the rest. A baseline shopper and a deep-dive shopper are buying two different products at two different prices, even though both start on the same $365 line.

Function Health Cost vs Superpower: The Annual Math

Here is the comparison most readers are really running. Both are annual memberships aimed at the same buyer: a health-conscious adult who wants a full-body picture once or twice a year.

Function Health is $365 per year for 160+ biomarkers, two draws, a urinalysis, and a 6-month retest. Superpower is $199 per year for 100+ biomarkers (about 150 once you count calculated ratios), one comprehensive annual blood draw, 17 plain-language health scores, a personalized action plan, and an AI concierge you can actually chat with about your results.

The honest read: Function Health gives you more raw markers and a second draw. Superpower gives you a cleaner once-a-year baseline, the interpretation layer (those 17 scores plus the action plan) that turns numbers into next steps, and it does it for $166 less per year. For someone who wants depth and a mid-year recheck, the extra spend on Function is defensible. For the much larger group who wants one clear annual snapshot they can understand without a clinician translating it, Superpower wins on value.

One thing the raw marker count hides: more numbers do not automatically mean more clarity. Function hands you a deeper data set, but you still have to know which of those 160+ lines matter for you. Superpower bets the other way, fewer markers but a built-in scoring and action layer, so the trade is depth of data versus depth of interpretation. Most first-time testers underestimate how much the interpretation side is worth until they are staring at a wall of slightly-off values with no idea which one to act on.

One pricing note that affects both: state lab rules matter. Superpower is $199 in most states but $399 in New York and New Jersey because of stricter direct-to-consumer lab regulations. If you live in either state, re-run the math before assuming the $199 figure applies to you.

How Do the Two Draws and 6-Month Retest Actually Work?

The two-draws-plus-retest cadence is the single feature that most justifies Function’s higher price, so it is worth understanding what it does rather than treating it as a marketing line. Most direct-to-consumer services hand you one annual snapshot. Function builds in a second draw and a retest window roughly six months later, which turns a photo into a short film.

Here is why that matters in practice. Say your first draw shows an elevated fasting glucose and borderline triglycerides. You change something, cut refined carbs, add walking after meals, lose a few pounds, and six months later you retest. Now you can see whether the change worked instead of guessing until next year. That feedback loop is the entire reason a tracker pays for the extra draw, and it is genuinely valuable if you are actively managing a metric.

The flip side is just as important. If you are not planning to change anything and recheck it, the second draw is capacity you paid for and will not use. A once-a-year baseliner gets almost no benefit from a mid-year retest, because there is no intervention to measure. This is the clearest place where the same product is a bargain for one buyer and an overspend for another, and knowing which one you are is worth more than any marker count.

Timing note. Six months is a sensible interval for most lifestyle changes to show up in bloodwork. Some markers move faster, glucose and triglycerides can shift within weeks, while others like HbA1c reflect a rolling average and need the full window to tell you anything real. Retesting too early is a common way to spook yourself with noise.

Is the Function Health Annual Membership Worth It?

Worth it depends entirely on which type of tester you are, and this is where Function Health pricing either makes sense or quietly overcharges you.

Function Health is worth $365 if you are a tracker

If you have a metric you are actively working on (cholesterol, fasting glucose, a thyroid number, a hormone you are managing) the two-draws-plus-retest structure is the whole point. You test, you change something, you retest at 6 months, you see if it worked. That feedback loop is exactly what the membership is built for, and at $365 it is fairly priced for that job.

It is probably overkill if you are a baseliner

If you mostly want to know roughly where you stand once a year and catch anything obviously off-range, you are paying for a second draw and a deeper marker count you may never act on. That is the classic mismatch: buying clinical-grade thoroughness when what you actually wanted was a clear annual checkpoint. In that case a leaner, cheaper full panel does the same useful work for less.

Themes users commonly report across this category line up with that split: people who treat results as a project love the depth, while people who wanted a simple yearly number sometimes feel they over-bought. Neither group is wrong; they just had different jobs to do. Be honest with yourself about which one you are before you pay, because the answer changes which price is the smart one.

How Do You Avoid Paying for a Bad Draw?

Whichever service you choose, a wide panel is only as trustworthy as the blood draw behind it, and small prep mistakes can distort several markers at once. Since you are paying real money for the numbers, it is worth getting them clean.

• Fast beforehand. Glucose, insulin, and the lipid panel need an empty stomach to read true, so an overnight fast of roughly 8 to 12 hours with water only is standard. Follow the specific instructions the service sends.
• Draw in the morning. Testosterone and cortisol follow a daily rhythm and run highest early, so a morning draw is both more accurate and easier to keep comparable across future draws.
• Pause high-dose biotin. Biotin, common in hair and nail supplements, can interfere with certain thyroid and hormone assays. Many labs advise stopping it a couple of days ahead.
• Skip hard exercise and alcohol the day before. An intense workout can transiently bump liver enzymes, and alcohol affects liver values and triglycerides, so an easy day gives a cleaner read.
• Do not test right after an illness. Inflammation markers spike during and after infection, so waiting until you have been well for a couple of weeks avoids a distorted baseline.

Consistency matters as much as the rules. If you are going to track year over year, draw under similar conditions each time, same fasting state, similar time of day, so your trend line reflects real change rather than testing noise. A cheaper panel drawn carefully beats an expensive one drawn on a bad day.

The Cheaper Alternative That Still Covers the Essentials

If the Function Health cost feels like more than you need, the alternative we keep recommending is Superpower, and the reason is specific rather than generic.

For $199 a year, Superpower gives you a comprehensive annual draw of 100+ biomarkers (about 150 with calculated ratios), then does the work most services skip: it translates those numbers into 17 health scores and a personalized action plan, and lets you chat with an AI concierge about what any result means. It is a screening and tracking service, not a diagnostic clinic, and it is upfront about that. For the person who wants a yearly full-body read they can actually understand and act on, that combination at $166 less than Function is the sweet spot.

The deciding question is simple. Want maximum marker depth and a mid-year retest, and willing to pay for it? Function Health at $365 is legitimate. Want one clear, interpreted annual baseline without paying for a second draw? Superpower at $199 is the smarter buy.

Whichever you choose, treat the results as information, not a diagnosis. Any biomarker that lands outside the normal range should be reviewed with a licensed clinician before you make decisions about treatment, medication, or major lifestyle changes. These services screen and track; they do not replace your doctor.

How Does Function Health Cost Compare to Testing Piecemeal?

A fair way to judge either membership is against the alternative most people default to: ordering tests one at a time when a symptom or worry pops up. That path feels cheaper because each order is small, but it rarely is once you add it up, and it gives you far less.

Consider a common year. You feel tired, so you get iron and thyroid checked. A few months later a physical flags cholesterol, so you pay for a lipid panel. Later you wonder about blood sugar and order an HbA1c. Three separate visits, three separate fees, three snapshots taken on different days under different conditions, and no single view that reads them against each other. You have spent real money and still cannot see how your ferritin, your CRP, and your glucose relate.

That is the quiet case for a bundled membership at either price point. Function’s $365 or Superpower’s $199 buys the whole board at once, drawn on the same day, interpreted together. The piecemeal route often costs more than it looks and delivers less clarity, because the value of a panel is in the cross-read, not the individual line. If you are the kind of person who ends up ordering scattered tests anyway, pricing a single annual panel against that habit usually makes the membership look like the disciplined choice rather than the expensive one.

Frequently Asked Questions

How much does Function Health cost per year?

The Function Health cost is $365 per year for the core membership, which includes 160+ biomarkers, two blood draws, a urinalysis, and a 6-month retest. Specialized add-on panels are priced separately, so your real first-year total can be higher if you add extras.

What is included in Function Health pricing?

Function Health pricing bundles 160+ biomarkers, two annual draws, a urinalysis, a built-in 6-month retest, and clinician-reviewed result summaries into the $365 flat fee. Advanced or specialty tests sit outside that fee and cost extra.

Is Function Health worth the cost?

It is worth it if you are actively tracking and changing a health metric, because the two-draws-plus-retest cadence is built for that. If you just want a once-a-year baseline, you are likely paying for depth you will not use, and a leaner panel like Superpower at $199 delivers the essentials for less.

Is Function Health or Superpower cheaper?

Superpower is cheaper at $199 per year versus $365 for Function Health, a $166 difference. Superpower covers 100+ biomarkers with 17 health scores and an action plan; Function offers 160+ markers and a second draw. Note Superpower is $399 in New York and New Jersey due to state lab rules.

Are there hidden fees with Function Health?

There are no hidden fees in the strict sense, but the $365 covers only the core panel. Specialized add-on tests (advanced cardiovascular, certain hormone, and toxin panels) are charged on top, so price the specific extras you want before assuming $365 is your total.

Does Function Health accept insurance or an HSA?

Function Health is a direct-to-consumer membership, so it is generally paid out of pocket rather than billed to insurance. Many people can use HSA or FSA funds for this kind of testing, but eligibility depends on your plan and administrator, so confirm before you assume the membership is covered.

Can you cancel Function Health after one year?

Yes. It is an annual membership, not a long-term contract, so you can decline to renew after your year. The thing to weigh is that the value compounds with tracking, so a one-year-and-done user captures the least benefit relative to what they paid.

Is $365 a good price for 160+ biomarkers?

On raw marker count it is competitive, and the bundled two draws, urinalysis, and 6-month retest add real value for a tracker. The honest caveat is that more markers do not automatically mean more clarity. If you will not act on the extra depth, a leaner panel like Superpower at $199 covers the essentials for $166 less.

How much should I actually budget for my first year?

Start at $365 for the base membership, then add the cost of only the specialty panels that answer your specific concern, cardiovascular, hormone, or toxin. A pure baseline shopper pays $365 and stops. A deep-dive shopper should price their add-ons first and expect a higher all-in number, so build your own figure before comparing it to any competitor.
