Quick answer: The Viome vs Function Health debate is a bit of a trap, because they are not measuring the same thing. Viome sequences your gut microbiome and cellular RNA from a stool (and sometimes saliva) sample to suggest foods and supplements. Function Health runs a large annual blood panel reviewed against clinical ranges. If what you actually want is a yearly full-body blood baseline you can track over time, our pick is Superpower: 100+ blood biomarkers, plain-language scores, and an action plan for $199 a year, which undercuts Function Health while covering the same screening job.

Viome vs Function Health vs Superpower: they answer different questions
The first thing to get straight in any viome vs function health comparison is that you are choosing between two different categories of test, not two versions of the same one. Buy the wrong category and the price difference stops mattering, because you paid for an answer to a question you were not asking.
Viome is a microbiome and RNA company. Function Health and Superpower are blood-biomarker companies. The honest way to decide is to start from the health question in your head, then match it to the test that answers it.
Viome: gut microbiome and RNA, not bloodwork
Viome analyzes a stool sample (and in some panels saliva) using RNA sequencing to profile your gut microbes and cellular activity, then turns that into food and supplement recommendations. Its flagship is marketed as a full-body intelligence test, but the input is your microbiome, not a blood draw. Viome does not measure cholesterol, fasting glucose, thyroid hormones, or a CBC, so it cannot replace standard bloodwork. Treat Viome pricing as per-kit or subscription and check the provider for the current number, since it runs frequent promotions and we will not quote a figure we have not verified.
Viome test reviews tend to split along one line: people who love a concrete food list walk away happy, while people expecting clinical blood markers feel the RNA-to-recommendation leap is hard to verify. Both reactions are fair. It is a personalization tool, not a diagnostic panel.
Function Health: the thorough annual blood membership
Function Health is a $365-per-year membership built around blood testing: 160+ biomarkers, two draws per year plus a urinalysis, and a 6-month retest built into the plan. That cadence is its strongest feature. Two scheduled draws plus a urinalysis make it the most clinically thorough of the three on the blood side, and the breadth of markers is genuinely deep.
The trade-offs are price and polish. At $365 it is the priciest option here, and its AI chat layer is newer than the rest of the experience. If you want maximum marker coverage and a built-in retest and the cost does not faze you, Function Health earns its keep.
Superpower: the full-body blood baseline at $199
Superpower is a $199-per-year membership: one comprehensive annual blood draw covering 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. It is built to give a health-conscious adult a clean yearly baseline and then track it, not to diagnose disease. (Membership runs $399 in New York and New Jersey because of state lab rules.)
Against Function Health it is the value play on the blood side: a bit fewer markers, one draw instead of two, but roughly half the annual price and a friendlier results layer. Against Viome it simply does a different job, the one most people picturing a full-body test actually have in mind.
Viome vs Superpower: microbiome RNA or full-body bloodwork?
This is the comparison most people mean when they search viome vs superpower, so it deserves a clear call. They overlap almost nowhere. Viome tells you about your gut ecosystem and which foods may suit it. Superpower tells you what your blood says about your metabolism, organs, hormones, inflammation, and nutrient status.
If your main concern is digestion, bloating, or building a personalized diet, Viome is the more relevant buy and Superpower will not give you a microbiome readout. If your concern is the broader stuff (cholesterol creeping up, blood sugar, thyroid, vitamin D, a yearly baseline to watch as you age) then Superpower is the right tool and Viome will not touch those numbers.
The genuinely informed move, if budget allows, is to treat them as complementary rather than competing: Superpower for the blood baseline, Viome for the gut layer. They are not rivals so much as different instruments.
Price and value: the real annual math
On the two blood memberships the numbers are simple. Superpower is $199 a year for 100+ biomarkers and one draw. Function Health is $365 a year for 160+ biomarkers, two draws, and a urinalysis. So Function Health gives you roughly 60% more markers and a second draw for roughly 80% more money.
Whether that premium is worth it comes down to one question: do you need the second draw and the extra marker depth this year, or do you mainly want a solid baseline you can trust and revisit? Most people in the screening-and-tracking bucket get what they need from the $199 tier, which is why Superpower is our default recommendation for this audience.
Viome sits outside this math entirely. Its pricing is per kit or subscription and aimed at diet personalization, so comparing its cost to a blood membership is comparing a recipe app to a lab report. Check Viome directly for current pricing before you buy.
Which one is right for you
Here is the short version of the three-way call, based on the job you are hiring the test to do.
- Choose Viome if your priority is your gut microbiome and a personalized food and supplement plan, and you understand it is not bloodwork.
- Choose Function Health if you want the deepest annual blood panel available here, two draws plus urinalysis, and the $365 price is fine.
- Choose Superpower if you want a comprehensive full-body blood baseline with plain-language scores and an action plan, at the best price of the three blood-screening options at $199 a year.
For the largest group of readers, a health-conscious adult who wants to know where their blood markers stand and watch them year over year, Superpower is the cleanest fit on value and usability. Function Health is the upgrade when you want maximum depth, and Viome is a separate purchase for the gut question.
One caveat that applies to all three: none of these services is a diagnosis. Any result that lands outside the normal range should be reviewed with a clinician before you act on it.
Full-body lab membership: 100+ biomarkers, doctor-reviewed, tracked over time.

Frequently asked questions
Is Viome better than Function Health?
Neither is strictly better, because they test different things. Viome profiles your gut microbiome and RNA to suggest foods, while Function Health runs a 160+ biomarker blood panel reviewed against clinical ranges. If you want bloodwork, Function Health (or Superpower at a lower price) is the right category. If you want gut and diet personalization, Viome is.
What do Viome test reviews generally say?
Common themes users report are that the personalized food and supplement lists feel novel and actionable, but that some buyers expected clinical blood markers and were surprised the test does not include them. The recurring lesson across viome test reviews is to know going in that it is a microbiome tool, not a blood panel.
How does the viome vs superpower decision actually break down?
Viome answers gut and diet questions from a stool or saliva sample. Superpower answers blood questions (metabolism, organs, hormones, inflammation, nutrients) from one annual draw of 100+ biomarkers for $199 a year. They barely overlap, so the choice is really about which question you want answered, and many people end up wanting both.
Can I replace a doctor’s blood test with any of these?
No. Superpower and Function Health are screening and tracking services, and Viome is a personalization tool, so none of them diagnoses disease. They are useful for spotting trends and starting conversations, but any out-of-range result should be confirmed and interpreted with a licensed clinician.
