Quick answer: Superpower vs Everlywell is really a choice between two different jobs. Superpower is a $199-per-year membership built around one comprehensive annual blood draw of 100+ biomarkers, plain-language health scores, and a tracking dashboard, so it is the better pick if you want a full-body baseline you can follow over time. Everlywell sells targeted at-home kits priced per test, which is the smarter buy when you only need to check one or two specific markers. For most people building a yearly health picture, we recommend starting with Superpower; keep Everlywell in your back pocket for one-off questions.

Superpower vs Everlywell: the core difference in one line
Everlywell is a store of individual tests. Superpower is a membership that draws a wide panel once a year and then helps you make sense of it. That single distinction drives almost every other decision here, so it is worth sitting with before you compare prices.
Think of it like this. Everlywell is buying the one ingredient a recipe calls for. Superpower is stocking a full pantry and getting a meal plan. Neither is wrong. They solve different problems, and the cheaper option is not automatically the better one once you account for what you actually want to learn from a Superpower blood test or any other panel.
How Superpower works and who it fits
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.
Superpower is a $199 per year membership. That fee covers one comprehensive annual blood draw measuring 100+ biomarkers (about 150 once you count calculated ratios), 17 plain-language health scores, a personalized action plan, and an AI concierge you can chat with about your results. In New York and New Jersey the price is $399 because of state lab rules, so check your state before you assume the lower number.
The point of Superpower is breadth plus continuity. You get metabolic markers, hormones, organ and kidney indicators, inflammation, and more in a single draw, then a dashboard that trends them year over year. It is a screening and tracking service, not a diagnostic clinic, so it is built for the healthy-but-curious person who wants a baseline rather than someone chasing a specific diagnosis.
Where it shines: you do not know which markers matter yet, you want the whole picture, and you want to watch numbers move after you change your diet, training, or supplements. That last part is the quiet advantage. A single test tells you where you are today. A tracked baseline tells you whether what you are doing is working.
How Everlywell works and who it fits
Everlywell sells at-home single-marker and small-bundle test kits, priced per kit, processed through CLIA-certified labs with results delivered online. You order the specific kit you want, collect a sample at home, mail it in, and read your result through their portal. It is clean, well-designed, and genuinely useful when your question is narrow.
Looking at Everlywell reviews across the category, the themes users commonly report are a smooth ordering experience, easy at-home collection, and clear digital results for the specific marker tested. The trade-off people also note is scope: a single kit answers a single question, so costs add up fast if you start buying three or four of them to approximate a broader panel.
Where Everlywell shines: you already know what you want to check (for example a thyroid marker, vitamin D, or a specific hormone), you want it done from home without a clinic visit, and you do not need a 100-marker context around it. For that targeted job, a per-kit purchase is often the most sensible spend.
At-home test kits for specific markers (metabolic, thyroid, hormones) shipped to your door.
What breadth actually buys you: the markers a single kit misses
The abstract argument (membership versus per-kit) gets concrete the moment you look at what a 100-plus marker draw contains that a one-marker kit never will. Individual markers rarely tell a clean story on their own. They earn their meaning in context, next to the other numbers that rise or fall with them. That context is the real product Superpower is selling, and it is worth seeing what sits inside it before you decide whether one Everlywell kit will do.
Metabolic markers work as a group, not alone
A fasting glucose kit can come back at, say, 96 mg/dL and look fine, since the standard normal range runs roughly 70 to 99 mg/dL. But glucose is a snapshot of one morning. HbA1c, which reflects your average blood sugar over about three months, tells a slower and often more honest story, with under 5.7 percent generally considered normal and 5.7 to 6.4 percent flagged as prediabetes. Add fasting insulin and the calculated insulin-resistance ratio, and you can catch a metabolism drifting the wrong way years before glucose alone crosses a line. A single glucose kit cannot do that. The panel can, because it reads the group together.
Cholesterol is more than the four numbers you already know
Most people have seen total cholesterol, LDL, HDL, and triglycerides. Fewer have seen ApoB, which counts the actual number of artery-clogging particles, or Lp(a), a largely genetic risk marker you usually only need to measure once in your life. Those two are frequently absent from a basic lipid kit and from a routine physical. When they show up next to your standard lipids, a “normal” cholesterol result can look different, and that is exactly the kind of insight a full panel surfaces that a targeted kit does not.
The quiet markers: iron, vitamin D, inflammation, thyroid
Ferritin (your iron-stores marker), vitamin D, B12, high-sensitivity CRP for inflammation, and thyroid values like TSH are the ones that most often explain vague, real symptoms: fatigue, low mood, poor recovery, brain fog. On a wide panel they get read side by side, so a low ferritin sitting next to a borderline thyroid and a low vitamin D starts to look like a pattern instead of three disconnected footnotes. Order any one of them as a standalone kit and you get the number, but not the pattern. Standard reference ranges for these vary meaningfully between labs, which is another reason a single out-of-context value is easy to misread.
None of this makes Everlywell wrong. It makes the choice honest. If your question genuinely is “what is my vitamin D,” a kit answers it cleanly. If your real question is “why am I tired and is anything drifting,” you want the group, not the single line.
Price and value: where the math tips
On paper Everlywell can look cheaper because you only pay for what you order. The math tips once you need breadth. Everlywell uses per-kit pricing that varies by test, so check the provider for current pricing on the specific kit you want. The moment you find yourself adding a second and third kit to cover metabolic, hormone, and inflammation markers, you are often spending in the same range as a Superpower membership, but without the dashboard, the health scores, or the year-over-year tracking.
So the value question is not “which is cheaper per test.” It is “how many markers do I actually want, and do I want to track them over time?” One or two markers: Everlywell usually wins on cost and convenience. A full baseline you plan to revisit: Superpower’s $199 for 100+ markers is hard to beat on cost-per-insight.

How to prepare so the numbers are actually real
Whichever route you pick, the result is only as good as the conditions you tested under. Direct-to-consumer testing puts you in charge of prep, and small mistakes quietly move numbers. Here is what changes a result, so you can control it instead of being surprised by it.
Fasting. Glucose, insulin, and the triglyceride portion of a lipid panel are fasting-sensitive. The standard guidance is 8 to 12 hours of water only before the draw. Eat breakfast first and your glucose and triglycerides can read higher than your true baseline. Water is not only allowed, it helps, because a well-hydrated vein is an easier draw and mild dehydration can nudge some concentrations up.
Time of day. Several hormones follow a daily rhythm. Cortisol is highest in the morning, and testosterone also peaks earlier in the day, which is why hormone panels are typically drawn in the morning. If you compare a morning draw one year to an afternoon draw the next, some of the change you see is the clock, not your body. Consistency matters more than the exact hour: draw at roughly the same time each year so your trend line is comparing like with like.
Exercise, alcohol, and illness. A hard workout in the day or two before a draw can transiently raise inflammatory markers and liver enzymes, so it is reasonable to keep the 24 hours before a draw easy. Alcohol the night before can affect triglycerides and liver values. And an active cold, flu, or recent infection raises inflammatory markers like CRP, so if you are sick, it is often worth rescheduling rather than testing a body that is mid-fight and reading a distorted picture.
Medications and supplements. Do not stop prescribed medication to “clean up” a test without talking to your prescriber. Do flag what you take, since biotin supplements in particular can interfere with certain lab assays, and high-dose vitamins can shift the very markers you are measuring. This prep discipline applies equally to a Superpower draw and an at-home Everlywell kit. The difference is only that a wide panel gives more numbers a chance to be thrown off by a sloppy prep, so it rewards doing it right.
The experience: collection, results, and follow-through
Collection is the most obvious lifestyle difference. Everlywell keeps everything at home with a self-collected sample, which many people prefer for convenience. Superpower centers on one comprehensive blood draw, which captures markers a finger-stick or home kit often cannot, at the cost of scheduling a draw.
Results tell a similar story. Everlywell gives you a clean readout for the marker you ordered. Superpower wraps your 100+ results in plain-language health scores, a personalized action plan, and an AI concierge that lets you ask follow-up questions about what a number means. If you have ever stared at a lab value with no idea whether it is good, that interpretation layer is the difference between data and direction.
One safety note for either service: any result outside the normal range should be reviewed with a licensed clinician. These are screening and tracking tools, not a diagnosis, and an out-of-range value is a reason to talk to a professional, not to self-treat.
Reading the report: what the scores do and do not tell you
The part that separates a membership panel from a stack of kits is not just the number of markers, it is what happens after the blood is drawn. Everlywell hands you a clean result for the marker you bought. Superpower groups your 100-plus results into 17 plain-language health scores by system, then layers an action plan and an AI concierge on top. It is worth being clear-eyed about what that interpretation layer is and is not.
What it does well: it turns a wall of reference ranges into a sense of direction. Instead of squinting at 30 metabolic values, you see a metabolic score and a short read on what is pulling it up or down. For someone who has ever held a lab PDF and felt nothing but mild dread, that translation from data to direction is the entire point, and it is genuinely hard to get from single kits bought one at a time.
What it does not do: replace a clinician. The scores and the AI chat are built for understanding and tracking, not for diagnosing a borderline or clearly abnormal result. Think of the concierge as a well-read study partner that helps you ask better questions, not as the doctor who answers them. A score that dips is a prompt to look closer and, if the underlying marker is off-range, to bring it to a professional. Used that way, the interpretation layer is the reason a wide panel is usable rather than overwhelming, which is exactly what a per-kit buyer trades away for a lower sticker price on a single answer.
Common misreads that trip people up
Getting more data creates a new problem: knowing what not to panic about. A few patterns come up again and again, and they apply whether your numbers came from a membership panel or a stack of single kits.
One flagged marker on a wide panel is normal. Reference ranges are built so that a slice of perfectly healthy people fall just outside them. Run 100-plus markers and it would be unusual for every single one to sit inside range. A lone, mildly out-of-range value is usually a reason to recheck and watch, not to diagnose yourself. This is precisely why breadth needs interpretation: more numbers means more statistical noise to read through calmly.
Labs and ranges vary. The same blood can produce a slightly different value at two different labs, and each lab prints its own reference range. That is why comparing an Everlywell result from one lab to a Superpower result from another is not always apples to apples, and why tracking within one service, year over year, gives a cleaner trend than hopping between providers for the same marker.
A single draw is a moment, not a verdict. Values move with sleep, stress, hydration, a recent meal, or a hard week. One reading tells you where you are on one day. This is the strongest argument for the tracked, repeat model: two or three data points across time tell you far more than any single heroic snapshot, which is the whole logic behind buying a baseline you intend to revisit.
Two quick scenarios to make the choice concrete
The curious 38-year-old with no clear symptom. You feel mostly fine but want to know your real numbers and whether your training and diet are working. This is the textbook Superpower case. You do not know which marker matters yet, so buying single kits is a guessing game. One wide draw maps the whole terrain, and next year’s draw tells you whether anything moved. Here, the membership is the honest spend.
The person with one specific question. Your doctor mentioned your thyroid last year and you just want to recheck TSH, or you started a vitamin D supplement and want to confirm it worked. You do not need 100 markers to answer that. A single Everlywell kit is faster, cheaper, and completely appropriate. Buying a membership here would be paying for 99 answers to questions you did not ask.
Our verdict: which should you buy?
If you want a complete, trackable picture of your health and you are not sure exactly which markers to chase, Superpower is the stronger choice. At $199 for 100+ biomarkers plus scores, an action plan, and a dashboard, it does the one thing single kits cannot: it gives you context and a trend line. That is why it is our default recommendation for anyone building a yearly baseline.
Everlywell earns its place when your need is specific. If you genuinely only want to check one or two markers from home and have no interest in a broad panel, a targeted kit is the honest, lower-cost answer, and there is no reason to oversell a membership you would not use.
A reasonable middle path many people land on: start with Superpower to map your full baseline, then use Everlywell for quick at-home rechecks of a single marker between annual draws.

Frequently asked questions
Is Superpower or Everlywell better for a full health check?
For a full health check, Superpower is the better fit. Its membership covers 100+ biomarkers in one draw with health scores and tracking, while Everlywell is built around individual kits that each test one or a few markers. If breadth and year-over-year trends matter to you, the Superpower blood test approach is more complete.
Is Everlywell cheaper than Superpower?
For a single marker, Everlywell is usually cheaper because you only pay for the one kit. Once you stack several kits to cover a broad panel, the cost often approaches Superpower’s $199 per year (or $399 in NY and NJ) without the dashboard or tracking. Compare based on how many markers you actually want, not the per-test sticker.
What do Everlywell reviews say about accuracy?
Everlywell uses CLIA-certified labs and delivers results online, and Everlywell reviews commonly highlight an easy ordering and at-home collection experience for the specific marker ordered. The recurring caveat users raise is scope rather than accuracy: a single kit answers a single question, so it is best for targeted testing rather than a whole-body baseline.
Can I use both Superpower and Everlywell?
Yes, and many people do. A common pattern is using Superpower once a year for the comprehensive 100+ marker baseline, then using an Everlywell kit for a quick at-home recheck of one specific marker between annual draws. They complement each other because one gives breadth and tracking while the other gives fast, narrow answers.
Do I need to fast before a Superpower or Everlywell test?
For the markers most people care about, yes. Glucose, insulin, and triglycerides are fasting-sensitive, so plan for 8 to 12 hours of water only before a Superpower draw, and follow the specific instructions on an Everlywell kit, since fasting rules depend on which markers the kit measures. Water is fine and actually helps the draw.
Why did one marker come back out of range on my panel?
On a 100-plus marker draw, a single mildly out-of-range value is statistically common and usually not alarming, because reference ranges are set so a portion of healthy people fall just outside them. Recheck it, look at related markers, and review anything clearly abnormal with a clinician rather than self-diagnosing from one line.
Can I compare an Everlywell result to a Superpower result for the same marker?
Loosely, but not exactly. Different labs can return slightly different values for the same blood and print their own reference ranges, so a marker measured through Everlywell one month and Superpower the next is not a perfect apples-to-apples comparison. For a clean trend on any single marker, track it within one service over time.
How often should I retest with Superpower?
The membership is built around a once-a-year comprehensive draw, which suits most healthy adults building and watching a baseline. If you are actively changing your diet, training, or supplements and want to confirm the effect, a targeted midyear recheck of the specific markers you are working on, often cheaper through a single kit, is a reasonable add.
