Who writes this
Plenta Health publishes plainly written guides to metabolic health, bloodwork, micronutrients and the everyday questions people search for. Every guide grades the strength of the evidence behind it and says where reading stops and a clinician starts. We are editors, not clinicians, and we say so on every page.
What we are not
Nobody on this desk holds a medical qualification. Not a doctor, not a dietitian, not a nurse. We do not run studies, we do not measure anything ourselves, and we do not diagnose. What we do is read the guideline, the database or the paper, write down what it actually says, and mark clearly where the question stops being one an article can answer. On a subject like this, being explicit about that is worth more than a credential we would have to invent.
The desk
Bram Ferreiro
Contributor, sleep and stress
Bram writes the sleep and stress entries. His working assumption is that anyone searching these topics has already read the standard advice and wants to know which parts of it are actually supported. He is not a clinician and holds no medical qualification, and he is careful to separate what is well established from what is a plausible mechanism with thin human evidence behind it.
Sleep · Stress & inflammation — 13 guides
Dev Petrossian
Contributor, heart and circulation
Dev writes the heart and circulation entries: blood pressure, cholesterol, resting heart rate. He treats these as measurement problems first — what the device is doing, what the number is sensitive to, and how much of an apparent change is real rather than noise. He is not a clinician and holds no medical qualification; the guideline thresholds in his entries are attributed to the body that published them.

Ines Calderon
Editor responsible for the metabolic health section
Ines edits the metabolic health section and the tools section. Most of her work sits in the gap between what a number on a lab report means and what a reader can actually do about it on a Tuesday. She is not a clinician and holds no medical qualification; what she does is read the primary sources, write down what they say rather than what they are usually reported to say, and mark clearly where a question stops being answerable by an article.

Lena Naumovska
Editor responsible for micronutrients and gut health
Lena edits the micronutrients and gut sections. She is unusually interested in dose, timing and absorption, because those decide whether a supplement does anything and they are the parts most articles skip. She is not a clinician or a dietitian. Where the evidence for a claim is thin she grades it thin rather than rounding it up, which makes some of these entries shorter and duller than the competition's.
Micronutrients · Gut health — 15 guides
Tomas Ottersen
Editor responsible for bloodwork and screening
Tomas edits the bloodwork and screening sections, one marker per entry. His view is that most confusion about test results comes from reference ranges being printed without the context that makes them mean anything: the assay, the population they were derived from, and everything that moves the number besides disease. He is not a clinician and holds no medical qualification, and every entry he edits names the guideline or database its ranges came from.

How we pay for it
There are no affiliate links on this site and no paid placements. Exactly one guide on the whole site reviews commercial products, it is in the toolssection, and it says on the page how it was put together. Everything else is here because somebody searched for it.
Corrections
If a figure here is wrong, or a source does not say what we attributed to it, that is the most useful thing you can tell us. We correct on the page and say what changed rather than editing quietly. Our full sourcing and grading rules are onhow we write.
