Structure/Function Claims: The Language Rules Brands Follow

Supplements may describe an effect on the structure or function of the body. They may not claim to diagnose, treat, cure, mitigate or prevent disease — that is a drug claim, and making it turns the product into an unapproved drug.

Hence the vocabulary. "Supports joint comfort" is a structure/function claim. "Relieves arthritis pain" is a drug claim. Same product, entirely different regulatory position.

"Supports", "helps maintain", "promotes", "aids", "contributes to" — all permitted. Each is doing the same job: asserting a directional influence on a normal body process without asserting a clinical outcome.

Read them literally and they are honest. "Supports a balanced inflammatory response" says the product plays some role in a normal process. It does not say your inflammation will decrease, and it does not claim any measured outcome.

Any product carrying structure/function claims must display: "These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease."

It is legally required, and it is also accurate. It is not fine print to skim past — it is the manufacturer confirming that nobody has reviewed the claim.

Compliant panels with non-compliant marketing is the standard pattern. Disease claims migrate into blog posts, social captions, affiliate copy and influencer scripts while the label stays clean.

Customer testimonials naming conditions are the most common vehicle. A brand cannot claim its product treats a disease, but it can republish a customer saying so — and regulators have consistently treated that as the brand's claim.

Do not assume cautious language means a weak product. A brand that words claims carefully is usually one paying attention to its obligations generally.

The inverse is more informative. A product promising to cure, reverse or eliminate something has told you it is either ignorant of the rules or indifferent to them, and neither is reassuring about what is in the bottle.
