How We Write Product Pages (And What We Leave Out)
Magnesium oxide is roughly 60 percent elemental magnesium by weight, while magnesium glycinate sits closer to 14 percent, and both figures are exactly the kind of thing we are allowed to print on a product page. The rule behind that is simple. A supplement is regulated as a food, not a drug, so our copy may describe structure and function: what a mineral does in the body and what it contributes to. The moment a page promises to treat, cure or prevent, it has crossed into drug territory, and we do not write pages that do that. It's a constraint, and we think it makes the copy better. That boundary isn't ours to redraw, and we wouldn't want to redraw it.
The line we write under
Structure and function language sounds like legal caution, and it is, but it is also a usable boundary. We can say a mineral contributes to normal energy metabolism or helps maintain normal muscle function, because those describe how the body works. We cannot say a product fixes anything, and we cannot name a disease as the thing a bottle is for. Every page we publish sits inside that frame, and the standard disclaimer at the foot of our pages is appended automatically rather than written by hand into the copy. Knowing where the fence is makes it easier to write useful things inside it.
Take magnesium as the running example. We can say it contributes to normal muscle function and to normal protein synthesis, because those are functions the mineral supports. We can't say it ends muscle cramps, because that tips into treatment, and treatment is where the drug line sits. The difference is narrower than it sounds and wider than it feels, and a lot of the loud copy online lives in the gap between them.
Numbers survive the filter
Structure and function claims sound vague until you attach figures, and the figures are public. The NIH tables put the magnesium requirement at 400 to 420 mg a day for adult men and 310 to 320 mg for adult women, with 350 mg set as the upper limit for supplemental magnesium. Against those references, a label stops being a mood and becomes a check. You can compare a 200 mg serving against what you already get from food and decide whether it earns a place in your routine. That is more useful than any adjective we could write, and it is the reason our pages lean on milligrams, counts and reference values instead of intensity words. You're free to run the same check on any brand's page, including ours. A page without figures is asking you to trust the tone of voice.
Does the filter make the copy vague?
It shouldn't. What it removes is the part of supplement copy that was never information: disease talk, dramatic promises, and studies cited as proof for a finished product when the research was done on ingredients. What it keeps is the checkable half. A page can still state the form, the milligram amount per serving, the count in the bottle, and where the reference value comes from. Vagueness is a choice. Specific doesn't mean loud. Specificity survives the filter if you were specific to begin with, and if a page was vague before the filter, the filter only exposes it.
What we leave out on purpose
We leave out guarantees, because a food cannot make them. We leave out disease language, because the law routes it to drugs and because it reads as pressure rather than information. We also leave out the habit of citing a study as if the finished bottle had been put on the bench, when the study was run on an ingredient at a dose you should be able to find on the panel. And when the honest answer is that a product is not the answer for someone, we say so, which is rarer on the internet than it should be. We don't dress that up as virtue. It's just the job. The result is calmer pages, and calm pages are easier to check, and easier to check is the entire point. None of this is complicated once you see the line, and the line does not move.
Frequently asked questions
Why do your pages avoid disease language?Show answerHide answer
Because supplements may only make structure and function claims. Anything stronger is a drug claim.
Does that make the copy vague?Show answerHide answer
It should not. Specific structure and function claims with numbers are still allowed.
Where do the study links go?Show answerHide answer
To the primary source - journal or PubMed record - never to a sales page.
