Function Health + SuppCo + Terra now cover the basics of biomarker tracking and supplement rating well. What they still don’t do: combo-stack reasoning (creatine + collagen interactions, magnesium glycinate vs threonate selection), women’s-cycle awareness, multi-modality integration (acupuncture, hypnotherapy, gait work), or clinical-protocol feedback loops with a credentialed practitioner.
The biomarker-and-supplement category just grew up
Through Q2 2026, three structural events reshaped the clinical-longevity tooling category:
- Function Health continued scaling its at-home bloodwork-plus-app model, with a clearer push into supplement recommendations
- SuppCo launched as a dedicated supplement-rating engine — Consumer Reports for supplements — with individual-product scoring
- Terra consolidated its position as the biomarker-data-integration layer connecting wearables, labs, and apps
For DAOM clinicians evaluating which tools to integrate into clinical practice, and for patients comparing these tools to multi-modality care, this piece names what each does well, what the collective gaps remain, and how to choose what’s right for your situation.
What Function Health does well (still)
Function’s 100+ marker comprehensive panel at-home, twice-yearly retest cadence, and clean app interface remain category-leading. The lab-orchestration work is still the strongest in the consumer space.
What’s new in Q2 2026:
- Tighter supplement recommendations now appear in-app post-results
- Clearer trend visualizations across multiple test cycles
- Better integration with select wearable data (via Terra-style middleware)
What still hasn’t materialized:
- A clinical-practitioner feedback loop. Function provides the data; you’re on your own to interpret deeply and intervene.
- Combo-stack reasoning. The app rates individual supplements; it doesn’t tell you what happens when you stack creatine + collagen, magnesium glycinate + threonate, or NAC + glutathione.
- Women’s-cycle awareness. Single-snapshot bloodwork without cycle-phase context misses what perimenopausal patients need most.
What SuppCo brings (and where it stops)
SuppCo’s individual-product rating model is a real category contribution. They evaluate single supplements on quality, evidence, and ingredient transparency — and the rating model is more rigorous than what existed before.
Where SuppCo doesn’t extend:
- Combo logic. Two SuppCo-5-star supplements taken together may have anti-correlated mechanisms. Individual ratings don’t capture this.
- Personalization. A 5-star magnesium isn’t 5 stars for you if your blood marker is already mid-range. Quality does not equal fit.
- Sequencing. When during your protocol do you add this supplement? Drop it? Cycle it? SuppCo doesn’t answer.
- Practitioner integration. Standalone rating tool, not connected to clinical care.
SuppCo is genuinely useful as a quality screen. It doesn’t replace the clinical-judgment layer.
What Terra connects
Terra is wearable + lab + app data middleware — the layer that makes Function bloodwork talk to your Oura ring talk to your sleep app talk to your supplement tracker. It’s infrastructure, not a consumer product.
Where Terra wins: It reduces the data-friction tax of running a longevity protocol. You don’t manually copy bloodwork numbers into spreadsheets anymore.
Where it stops: Terra moves data; it doesn’t reason about it. The interpretation layer is still missing.
The remaining category gaps (as of May 2026)
Five gaps that none of the major tools currently fill:
- Combo-stack reasoning. What 3-5 supplements give you 80% of the benefit for your specific bloodwork?
- Women’s-cycle awareness. Bloodwork phase, supplement timing, and intervention sequencing all change for perimenopausal/menopausal patients.
- Multi-modality integration. Bloodwork can flag inflammation, but only acupuncture + nervous-system rehab + targeted nutrition together resolve it. Single-vector apps miss the integration.
- Functional specialty panels. Beyond the standard 100+ marker panel — most users don’t know what specialty test to run when.
- Clinical-protocol feedback loop. A credentialed practitioner integrating data with intervention, then re-measuring, then adjusting.
What this means for patients
If you’re a patient with stable biology, simple goals, and budget for membership tools, Function + SuppCo + Terra gives you a strong starting stack. You’ll learn a lot about your own biomarker trends and supplement options.
If you have complex chronic conditions (Long COVID, MCAS, perimenopause, post-concussion, hormone imbalances, autoimmune patterns), or you’ve already tried the consumer-tooling layer and plateaued, you’ll likely need a clinical-integration layer that the consumer apps don’t provide.
That’s the gap AI Longevity Pro is designed to close when it launches to beta on June 1. It pulls biomarker data (via Terra-style integration), reasons about combo-stack logic, accounts for women’s-cycle phase, and integrates back into the multi-modality framework I use at the Tustin clinic — connecting the consumer tools to actual clinical interpretation.
Common questions
Q: Should I use Function + SuppCo + Terra together?
Yes, if you want the comprehensive consumer tooling. Function for bloodwork, SuppCo for supplement quality screening, Terra to keep your wearable + lab data in sync. Plus a clinical practitioner for interpretation.
Q: Is Function Health worth $499/year?
For most patients running a longevity protocol seriously, yes. Twice-yearly comprehensive panels at $499 is competitive with conventional labs at half the marker depth.
Q: When does SuppCo actually save money?
When it stops you from buying 3 mid-quality supplements you were stacking for the same benefit, and points you toward 1 high-quality one. Probably saves 20-40% on a typical supplement budget over 12 months.
Q: What’s AI Longevity Pro and why should I wait for it?
AI Longevity Pro is launching to beta June 1, 2026 (official July 1). It’s the clinical-interpretation layer the consumer tools are missing — built on the Four Layers framework I use at the Tustin clinic. Waitlist-only until June 1.
