Marek vs Geviti vs Function Vs Mito Health: Functional Medicine Compared

These five do not price the same way, so comparing a single number is misleading. Mito Health is a one-time $399 test. Function Health is a $365 yearly membership that includes two panels. Geviti is a membership starting around $67 per month (billed $400 every six months for the Lite tier), rising to about $130 to $150 per month for tiers that add prescriptions. Marek Health charges roughly $225 per month for its coaching program, with lab panels billed separately, so real first-year spend often runs $2,500 or more. OneTwenty is $499 per year, with medications and supplements billed as needed.

The more useful question is not the sticker price but how often you are actually tested for it, because that determines whether you get a yearly snapshot or an ongoing picture of your health.

A standard annual physical usually runs fewer than 20 markers, leaving out advanced cardiovascular risk markers like ApoB and Lipoprotein(a), full hormone and thyroid panels, inflammatory markers, and nutrient status. Every platform here tests those deeper markers. The differences come down to three things: how often they test you, whether they only test or also treat, and whether they fold in data from your wearables and daily life.

On one end, Mito Health and Function Health are testing-first platforms that give you a thorough panel and a plan. In the middle, Geviti adds a membership cadence and prescription access on higher tiers. Marek Health is a hormone-optimization specialist with the deepest diagnostics and a treatment menu to match. And OneTwenty sits at the far end, combining quarterly labs with continuous wearable data, supplements, prescriptions, and a plan that is actively re-tuned every quarter.

These two are the closest match in this group, so it is worth isolating. Both test 100+ biomarkers and both include clinician interpretation. The difference is structure. Mito Health is a one-time $399 test with an AI advisor and a 1:1 consult, ideal for a thorough baseline. Geviti is a membership starting around $67 per month that includes two panels a year and, crucially, at-home blood draws in major metros.

Choose Mito if you want a single deep snapshot with strong interpretation and a biological-age readout. Choose Geviti if you want ongoing twice-yearly testing and the convenience of a draw at home. And if you want more frequent testing layered with wearable data and the ability to actually treat what the labs find, that is where OneTwenty goes further than either.

At $499 per year, OneTwenty is not the cheapest entry here, but it is the only one doing continuous optimization rather than periodic testing. For that price you get four lab panels a year, 500+ daily signals from your wearables, a 24/7 AI Health Coach, custom supplements formulated from your results, and prescription access through licensed clinicians, with your protocol adjusted every 90 days. Marek goes deeper on hormones but costs far more and is unavailable in New York. Function and Mito test thoroughly but cannot treat. Geviti adds convenience but tests half as often and skips wearables.

If you only want a single snapshot, a cheaper one-time test will do the job. If you want your health actively managed and adjusted as your body changes, OneTwenty is the only option here built for that, and it works in all 50 states.

The right platform depends on what you want. For the deepest hormone work, Marek Health is unmatched, if you can afford it and live outside NY, NJ, and RI. For comprehensive screening at a fair price, Function Health is the value pick. For at-home convenience, Geviti. For a single thorough baseline, Mito Health.

But if you want a platform that does not just test you and hand you a report, one that monitors your biology continuously and adjusts your plan as your body changes, OneTwenty is the clear choice. Quarterly labs, 500+ daily signals from your wearables, an AI health coach, custom supplement delivery, and prescription access, all in one membership, re-optimized every 90 days, available in all 50 states. No other platform here combines testing, monitoring, and treatment this completely.
