Our approach
An NHS blood test checks about ten markers against ranges designed to detect illness. You can be "in range"and still feel tired, foggy, or undertrained — because "not sick" is a low bar. The thresholds were never meant to tell you how to feel your best.
We test fifty-plus markers — hormones, thyroid, inflammation, vitamins, minerals, metabolic, liver — and read them against the optimal ranges longevity researchers use, not the wider ranges designed to catch frank disease. Results land in five days, reviewed by a GMC-registered doctor, written in plain English you can read without a medical degree.
Then we tell you what to do about it. Not a generic "supplement stack" pulled from a quiz. Just the three or four things your blood says you actually need — and a follow-up test in three months to prove it worked.
The Helvy team
Why ranges matter
Your GP uses wide reference ranges designed to catch disease. You can sit inside "normal" and still feel terrible — because the range was never built to tell you how to feel your best.
We read your results against the tighter ranges used by longevity researchers and sports medicine physicians. The difference is the gap between not sick and actually thriving.
Vitamin D
nmol/L
In range — but suboptimal
Ferritin
µg/L
In range — but dragging energy
Vitamin B12
pmol/L
Optimal — you're thriving
TSH
mIU/L
In range — but sluggish thyroid
Illustrative example. Optimal ranges sourced from longevity medicine literature.
The Protocol
01
Test
A finger-prick at home — three minutes. Drop the sample in the post in our prepaid envelope. Processed at UKAS-accredited UK laboratories the day it arrives.
02
Understand
Fifty-plus markers reviewed by a GMC-registered doctor, written up in plain English with performance ranges. You see what's optimal, what's borderline, and what needs attention — no medical degree required.
03
Optimise
A short list of supplements personalised to what your blood actually shows. Three or four things, not thirty. A follow-up test in three months to verify it worked.
What arrives
Your kit arrives in discreet packaging within two working days. The whole process — from opening to posting — takes about three minutes. No appointment. No clinic. No waiting room.
Samples are collected via a simple finger-prick lancet and posted back in the prepaid envelope. They reach the lab the next working day. Results land in five.
Kit contents
Collection tube
Pre-labelled, barcoded to your order. Holds the sample for transport to the lab.
Lancets
Single-use, spring-loaded. A brief press on the fingertip — most people barely feel it.
Alcohol wipes
To clean the collection site before and after. Sterile, individually wrapped.
Plasters
Small adhesive plasters for after collection. The puncture is tiny.
Instructions card
Step-by-step visual guide. Clear enough that you won't need the video — but the video exists too.
Prepaid return envelope
First-class Royal Mail. Drop it in any postbox. No printer, no label, no trip to the post office.
Free delivery. Discreet packaging. No branding on the outer box.
What we test
Your GP checks around ten. We test across every system that affects how you feel, perform, and age — from hormones and thyroid to heart risk markers most NHS panels miss entirely.

Total biomarkers in our Performance panel
A standard NHS check covers ~10. We test five times more.
Your results
Every biomarker rated against the optimal ranges, not just the disease thresholds your GP uses. You see what is thriving, what is borderline, and what needs attention.
Plain English. No jargon. One page of priorities instead of thirty pages of numbers.

Turns out my Vitamin D was half what it should be. No wonder I felt rubbish every winter. Two months of the right supplement and the difference is night and day.
I was spending £80 a month on supplements I didn't need. Helvy showed me I only actually needed three things. Saved money. Feel better.
My recovery was awful despite doing everything right. The blood test showed my ferritin was tanked. Fixed it in six weeks.
I told my GP I was tired all the time. They said I was fine. Helvy found my B12 was borderline and my thyroid was sluggish. Finally got answers.
Examples based on typical outcomes.

Your GP typically tests about ten markers, using ranges built to catch disease. Helvy tests fifty-plus markers, read against the narrower ranges longevity researchers use to spot what is keeping you below your best. We are not trying to diagnose disease. We are trying to surface what is holding you back.
It's a simple finger-prick — three minutes at home. No needles, no clinic visits. Most people say it's easier than expected.
We only recommend supplements that directly address what your blood test shows is low or suboptimal. If your levels are fine, we'll tell you to save your money. It's that simple.
Great news — you'll know you're in good shape. We'll still show you where you could optimise further using performance ranges, but we'll never push supplements you don't need.
Every blood test is processed by a UKAS-accredited UK laboratory and reviewed by a GMC-registered doctor before you see your results.
