Prove the bar does something.
A protein or functional bar makes a metabolic promise. Run a cohort on it for twelve weeks and we read the metabolic panel before and after — a measured profile shift that stands behind the claim, not a taste-test and a stock photo.
The claim at stake
"Supports metabolic health" needs more than a label. Functional-food claims live or die on evidence. A measured biomarker signature — the cohort's metabolic markers before and after — is the difference between a marketing line and a defensible one.
A promise on the wrapper
Taste panels, influencer posts and a health-halo — nothing a regulator, retailer or skeptic can check.
marketing · not measured
A measured profile shift
The cohort's own panels, before and after, read into a per-axis delta with significance — the claim, quantified.
paired · Δ · p-value
A claim you can defend
Evidence to put in front of retail buyers, regulators and partners — and an R&D baseline for the next formulation.

How the engine applies
One trial's panels in, a signature out. You bring the cohort's before/after lab panels; the engine reads the metabolic axis, computes the paired shift and significance, and returns a Signature Report that backs the claim.
The axis we read
For a metabolic bar, the metabolic panel. The axis depends on what the product does; for functional food aimed at metabolism, these are the markers that move.
Glucose & insulin
Fasting glucose and insulin — the base of any metabolic-flexibility read.
GLU · INSULIN
HOMA-IR
Insulin-resistance index derived deterministically from glucose and insulin.
HOMA-IR · threshold > 2.5
Triglycerides & HDL
The lipid side of metabolic response — often the first to move on a dietary change.
TG · HDL
HbA1c (if the window allows)
For longer cohorts, the glycation trend that a twelve-week panel starts to show.
HBA1C · trend
Who this is for
Any brand whose bar makes a functional promise. If the selling point is a physiological effect — not just the macros on the label — there's a biomarker that should move, and a cohort that can prove it.

Logos shown are market examples of each segment, to illustrate who the application fits — not Zenlo clients or partners, and no endorsement is implied. The fit is the claim type, not the logo.
What this is — and isn't
Evidence for a claim, not a health claim
We measure what moved in a cohort and hand you the trail. We don't manufacture the result, and we don't make medical claims on the product's behalf.
Illustrative application
This page shows how the engine would apply to a functional-food trial.
- No named client or product
- Numbers shown are example endpoints
- The real signature comes from your data
The cohort owns the result
The signature is whatever the panels say — up, down, or flat.
- Paired before/after, with significance
- Drivers named; nothing cherry-picked
- Reproducible from the same inputs
Not a medical claim
A measured biomarker shift is evidence, not a diagnosis or a treatment claim.
- For product substantiation & R&D
- Claims language stays the brand's responsibility
- Zero data retention on model calls
Turn your trial into a signature.
Send one trial's before/after panels and we return a Signature Report: the measured metabolic shift, with an evidence trail your buyers and regulators can check.
