1. What this publication is
Naturally Immune MD is an evidence review. It examines natural ingredients, immunity and preventative skin health, and it grades how strong the evidence behind each claim actually is. It is published by Northbank Media.
The reason it exists is a gap. There is an enormous amount of writing about vitamins, botanicals, supplements and skincare, and almost all of it falls into two camps. One camp sells. The other debunks. Both are unsatisfying, because most ingredients are neither miraculous nor worthless: they have an evidence base of a particular shape, and that shape is the useful information. Describing it accurately is the whole job here.
2. How the reviews work
Every review opens with an overall evidence grade and a claim-versus-evidence table, because an ingredient does not have one evidence base. It has one per claim. Zinc is essential in deficiency and unhelpful above it. Vitamin D is necessary and oversold. Collapsing those into a single verdict destroys the only information a reader needed.
Grades are qualitative: Strong, Moderate, Limited, Insufficient. They describe the depth, consistency and independence of the human research behind a claim. They are not scores, ratings or rankings, and they cannot be bought. The full method is set out in how we grade evidence.
3. What we do not do
We do not invent study specifics. No fabricated author, journal, sample size, p-value or effect size appears anywhere on this site. Where we describe an evidence base we describe its shape: roughly how much controlled human research broadly exists, how large and how long it typically is, who funded it, what has been replicated and what is missing.
We do not review named commercial products or brands. Grades attach to ingredients and claims, which removes the mechanism by which a review site becomes a shop.
We do not take affiliate commission, sponsorship, samples or payment for coverage. We do not run sponsored posts and no company previews a grade before publication.
We do not give medical advice. This is a review of published evidence written for general readers. If you have a condition, a suspected deficiency, a changing mole or a reaction to a product, that is a conversation with a pharmacist, a GP or a dermatologist.
4. On tone
We try to write plainly and to say when something is weak, including when that undercuts a popular ingredient. Several categories reviewed here have very large markets behind them and carry Limited grades. That is not contrarianism. It is what the evidence supports, and we would raise those grades tomorrow if adequate independent trials appeared.
We also try to avoid the opposite failure. A Limited grade is not a claim that something does not work. It means nobody currently knows, and the correct response to not knowing is caution rather than certainty in either direction.
5. Who writes it
Reviews are researched and written by the editorial team at Northbank Media and reviewed before publication against the standards on this page and in our editorial policy. We do not present individual authorship as a credential, and we do not use the initials in the title to imply that any specific clinician endorses a particular conclusion. Where a question requires clinical judgement about an individual, we say so and point to the NHS, NICE or the British Association of Dermatologists rather than answering it.
6. Funding and the one disclosed exception
The publication is funded by its publisher. It carries no advertising, no affiliate links and no sponsored content.
There is one disclosed exception and it is described in full in the editorial policy. Four archive articles carry a single editorial link each to a named organisation. Those links were placed editorially, were never sold, and each of the four articles carries a publisher disclosure block naming Northbank Media at the foot of the page. Every other page on this site carries no commercial link at all and says so explicitly.
We consider that arrangement worth stating openly rather than burying, because a publication that grades other people's conflicts of interest has no business concealing its own.
7. Corrections and contact
If something here is wrong, we want to know. Tell us, with the page and the reason. Substantive corrections are made on the page. Every page carries the date it was last reviewed.
