Evidence-based, educational only

How we research

Every review explains what the published guidance says and attributes it to the body that publishes it, so you can check the current figure yourself. This is evidence-based general information, written to be educational, not medical advice, and never a substitute for your own clinician.

How we make money

At the time of writing this site carries no affiliate links and no advertising. No link earns a commission and no company pays for coverage. If that ever changes, the disclosure page will say so first and any paid link will be marked where it appears.

How an evidence review is researched

Every review moves through the same four steps, from source to plain-language draft, so the numbers you read are traceable.

Step 1

Start from the sources

Every review begins with published clinical guidance and names the body that issues it, not opinion or a single headline. We run no studies and no surveys of our own.

Step 2

Translate, do not dilute

We rewrite the findings in plain language, keeping the ranges, caveats, and uncertainty that the science actually carries.

Step 3

Accuracy check

Figures are presented as commonly cited ranges attributed to the body that publishes them, so you can check the current number at the source, and never as personal targets. This is evidence-based general information, not medical advice.

Step 4

Update and correct

When guidance changes or a reader flags an error, we verify it, fix it, and refresh the article’s updated date.

Editorial standards

The commitments behind every NourishMark review.

Education first: our reviews explain general evidence and never diagnose, prescribe, or replace your own clinician.
Guideline figures are presented as commonly cited ranges, not personal targets set for you.
We work from recognized clinical guidance and point you to the publishing authority rather than quoting a figure you cannot check. NourishMark is not a clinic, a lab or a practice, and the only clinician here is our named medical reviewer.
This site carries no affiliate links and no advertising. No link earns a commission. Nothing commercial influences medical accuracy or what we recommend.
Verified corrections are made promptly and the article’s updated date is refreshed.
