REVI CUSTOMERS

Different starting points. Clearer next steps.

Real experiences from early Revi members—and the findings that changed what they did next.

CLARITY INTO ACTION

Started monitoring his glucose

“At first, I thought this might be just another blood test. Instead, Revi showed me exactly what mattered and what to do next. I’m taking my health far more seriously now and have started monitoring my glucose.”

Harry E.

Business owner, 53

CONNECTED PATTERN

Connected diet, nutrients and hormone availability

“I follow a carnivore diet and had no idea I was low in several nutrients—or that under-fuelling might be affecting my hormone availability. Revi connected the findings to my routine in a way I could actually understand and act on.”

John C.

Self-employed, 37

INHERITED RISK

Prompted a conversation with his family

“Finding out my Lp(a) was high was a real wake-up call. Revi explained what it meant, what I could still control and why my family should consider getting tested too.”

Jonny K.

Founder, 37

After joining, you complete a short health and lifestyle intake form and book a venous blood draw with our laboratory partner. You will receive preparation instructions before your appointment, including whether you need to fast. Your laboratory results are then combined with your biometrics and current routine to build your Revi assessment.

You receive a private Revi report showing your longevity and system scores, the few opportunities expected to matter most, and an exact plan across nutrition, training, supplements and lifestyle. It also includes evidence-informed targets where change can be defensibly projected, focused retesting recommendations, GP flags and a one-to-one results review.

Most blood tests report individual results against laboratory reference ranges. Revi connects your biomarkers, biometrics and current routine across eight longevity systems, compares the opportunities across your full health picture and ranks the few changes expected to make the greatest difference from your starting position.

Each biomarker is assessed using the standard laboratory range and, where available, an evidence-informed Revi optimal zone. Related markers are combined into system scores, while patterns across your results, biometrics and routine are used to identify and rank your highest-impact opportunities. These scores are decision tools for health optimisation, not medical diagnoses.

The Revi Elite Baseline is a one-off complete assessment, personalised plan and results review. The Annual Membership includes everything in the Baseline, focused retesting at 24 weeks, an updated review and plan, and a new complete assessment when the annual membership renews.

No. Revi provides health education, interpretation and optimisation guidance; it does not diagnose conditions or replace medical care. Where a result may need clinical investigation, medication review or treatment, your report will clearly recommend discussing it with your GP or prescribing clinician.

Your results are treated as sensitive health data and used to provide your Revi assessment and associated services. Revi uses technical and organisational safeguards, limits access through its service providers, and sets retention periods for different data types. Full details on storage, access, retention and your rights are available in the Revi Privacy Policy.
