Life Force vs Function Health vs Fountain Life

The price gap here is enormous, and it is the first thing to understand. Function Health is $365 a year for two panels. OneTwenty is $499 a year for quarterly testing plus monitoring, supplements, and prescription access. Life Force is $129 a month (or $1,449 a year) plus a $349 starter diagnostic, which puts year one around $1,900 before any medications or supplements. Fountain Life is in a different universe: its CORE tier runs roughly $3,000 to $10,500 depending on location, APEX is about $19,500 to $21,500 a year, and the EPIC tier is around $85,000 by application.

What you are paying for changes as you go up. Function and OneTwenty are accessible memberships. Life Force adds at-home convenience and a clinician relationship at a premium. Fountain Life is buying advanced imaging like whole-body MRI and coronary CT, which the others do not offer at all. The right question is not which is cheapest, but which level of testing, treatment, and imaging actually matches your goals.

A standard annual physical runs fewer than 20 markers and skips much of what matters for optimization: advanced cardiovascular risk, full hormone and thyroid panels, inflammation, and nutrient status. All four platforms go deeper, but in very different ways.

Function Health and OneTwenty are membership programs that test your blood regularly and build a plan from it, with OneTwenty adding wearable data, supplements, and prescriptions. Life Force sends a phlebotomist to your home, then pairs your results with a clinician who can prescribe hormones, peptides, or GLP-1s. Fountain Life is a clinic-based concierge program where the centerpiece is advanced imaging, whole-body MRI, coronary CT, and DEXA, completed in a single intensive day and interpreted by a dedicated care team. Different tools, different budgets, different goals.

These two get compared a lot, but they solve different problems. Function Health is testing-first: $365 a year for two broad panels, clinician notes, and an action plan, with no prescriptions. Life Force is treatment-first: a clinician who reviews your at-home results every quarter and can prescribe hormones, peptides, or GLP-1s, at roughly $1,900 in year one.

Choose Function Health if you mainly want thorough, affordable testing and will act on it yourself. Choose Life Force if you want a clinician relationship and prescription access without leaving home, and the premium fits your budget. If you want both the testing depth and the treatment, plus wearable data and delivered supplements, OneTwenty combines them for $499 a year, less than half of Life Force's annual cost.

At $499 a year, OneTwenty is priced near Function Health but does far more, and it does much of what Life Force does for less than half the cost. You get four lab panels a year, 500+ daily wearable signals, 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. The one thing it does not offer is the advanced imaging at the heart of Fountain Life, which is a different product for a different budget.

If you want a thorough annual snapshot, Function Health is cheaper. If you want whole-body imaging and have the budget, Fountain Life is in a class of its own. But for ongoing, hands-on optimization at a sane price, OneTwenty is the most complete option here.

The right pick depends on budget and goals. For thorough testing at the lowest price, Function Health wins at $365. For an at-home program with a clinician who can prescribe, Life Force is strong if the premium fits. For the deepest look inside your body through advanced imaging, Fountain Life stands alone, for those who can afford it.

But for most people who want ongoing optimization rather than a snapshot or a once-a-year scan, OneTwenty is the most complete option that does not require a concierge budget. Quarterly labs, 500+ daily wearable signals, an AI health coach, custom supplement delivery, and prescription access in one $499 membership, re-optimized every 90 days, available in all 50 states. It delivers most of what the pricier programs do, for a fraction of the cost.
