Helvy
Full transparency
Who pays for something shapes what it tells you. So here it is, plainly: Helvy is paid by the people it tests, not by advertisers or supplement brands. That single fact is why we can tell you to save your money when your results are fine.

How Helvy makes money
You buy a blood test
Our panels start from £99. That price covers the kit, the analysis at a UKAS-accredited UK laboratory, and the plain-English report that reads your results back to you. This is the main way Helvy is paid.
You join the Helvy Plan
Some people choose an ongoing plan that retests over time and tracks how their markers move. It is a subscription you can cancel — not a lock-in, and never a requirement to get your results.
How we don't
We do not sell ads
There are no display ads, no advertorials, and no third parties paying to appear in our guides. Our guides are not for sale.
We are not paid by supplement brands
No supplement company pays us to recommend it. When a result points to a genuine gap, we say what the evidence supports — and if your levels are fine, we tell you to save your money.
We do not sell your data
Your health data is Special Category data under UK GDPR. We never sell it, and we never share your individual results with an advertiser, insurer or employer.
We do not pay for reviews
We do not buy testimonials or incentivise ratings. Any review programme we run pays no one to say something they do not believe.
Why we tell you this
The honest version is the whole point. When our income depends on your test and nothing else, the incentive is to be right and to be clear — not to sell you a supplement you don't need or an upgrade your results don't justify.
