Health-claim checks that people do not learn to ignore

The failure mode for any automated health-claim check is not missing things. It is training the marketer to click past it. A tool that flags forty trivia items on a label ends up ignored on the three that draw an FDA warning letter. A pre-publish check has to earn its seat on every run: deliberate about what it blocks on, what it warns about, and what it refuses to judge. The supplement-claim framework is genuinely useful here as an ordering of attention, because it already distinguishes wording that is categorically unlawful for a supplement from wording that merely needs a disclaimer or a named basis.

Block on what is categorically wrong in the wording

Some constructions are facts about the paste, not opinions about your product. A claim that the supplement treats, cures, prevents, or reverses a named disease is the defining line of the structure/function regime in 21 CFR 101.93: it makes the product an unapproved drug claim regardless of how good the rest of the label is, and no disclaimer cures it. So is stating, or implying, that the FDA "approved" or "certified" the supplement — supplements are not pre-approved, so that phrasing misrepresents the law outright. Block on these before print, because these are the findings that escalate. The only honest uncertainty is how a given reviewer will weigh them — not whether the gap exists in the text.

Warn on what is probably fixable

The middle tier is where a good tool earns its keep. A lawful structure/function statement — "supports immune health," "promotes restful sleep" — that is missing its mandatory 101.93(c) disclaimer is usually a one-line fix. A "clinically proven" or "studies show" cue with no named basis is the same shape: the FTC wants competent and reliable evidence on hand, and the fix is to cite the specific study or narrow the claim to what it actually showed. Absolutes like "no side effects" or "guaranteed results" belong here too — sharpening attention on a word that is almost always overstated, without pretending to be a legal ruling. Warn, quote the sentence, and let a human attach the evidence.

Leave alone what cannot be decided from the text

Whether your trial actually measured what the claim says, whether a per-serving nutrient amount clears the "high in" threshold in the nutrient-content rules (21 CFR 101.13, with labelling detail in 101.9), whether your facility registration is current — those live in study reports, panels of record, and certificates, and a health-claim checker that pretends otherwise is producing confident noise. The honest move is to say plainly: I read your wording; I cannot verify your evidence. A tool that scores a "compliance probability," or claims your label is "FDA-cleared," is lying about what a text scan can do.

Rule logic beats a banned-word list

The naive approach is a list of forbidden phrases: block "cure," block "clinically proven," block "immunity." It fails twice. First, it blocks lawful uses — "supports healthy immune function, statement not evaluated by the FDA" is a fine structure/function claim, and a flat word list flags it as a false positive while letting through a paraphrase that names a disease obliquely. Second, the rules are not a word list at all; they turn on what a claim means — disease vs function, disclaimer present vs absent, proof asserted vs cited — and on context the sentence alone cannot show. Whether the qualifying language is present is deterministic to check; whether the underlying evidence is real is not, and a tool that conflates the two loses trust.

The tiers shift with surface

A claim baked into a product or brand name has almost no room to carry a disclaimer or a citation, so it deserves stricter handling than the same claim in body copy where the 101.93 disclaimer can sit right beside it. A pre-check that lets you say the surface — label, ad, web page, brand name — and escalates accordingly is more useful than one that treats every paste identically, because "clear and conspicuous" and "accompanied by" are statements about how a real shopper sees the claim in a real place.

A habit that stays alive

Teams who keep a health-claim check alive run it on a fixed cadence: one scan per label or ad draft, before print, never after the packaging file is locked. The scan stays fast because it is mechanical — locate disease verbs near disease names, spot structure/function verbs, look for the disclaimer, catch "proven"/"approved"/absolute cues — and produces the same ranks every time against the same published rules. If the block tier is cleared before a human reads the draft, the human then spends their effort on the evidence the tool deliberately refused to invent, and the check earns its place instead of being muted in a week.

Heuristic pre-check only — not a health-claims certification or legal advice. No clinical-trial, lab, facility-registration, or FDA-approval verification is performed; those facts live outside the wording a checker can read. For binding guidance, consult 21 CFR 101.93 and a qualified professional.
