Claim language guide
Supplement claim words: what the evidence should prove
Detox, immune, anti-aging, and mood-support language shapes the pitch before readers reach the ingredient list.
The quick read
- FDA does not approve dietary supplements for safety or effectiveness, or approve their labeling, before sale. Manufacturers remain responsible for lawful labels, and readers can still check the supporting evidence. FDA 101 dietary supplements FDA supplement claim substantiation guidance
- FTC expects health and wellness claims to rest on competent and reliable scientific evidence rather than on a well-written label sentence. FTC health products compliance guidance
- Clean, natural, immune, detox, and anti-aging start meaning something once they are attached to an ingredient and an amount. FDA dietary supplement labeling guide FDA 101 dietary supplements FDA supplement claim substantiation guidance
- Supplement Facts is where the math starts. The promise line on the front is not part of it. FDA dietary supplement labeling guide
What the evidence says
Bottom line
A front-panel word becomes auditable when it is tied to a named ingredient form, a per-serving amount, and evidence relevant to both. FDA supplement claim substantiation guidance FDA dietary supplement labeling guide
Claim vocabulary becomes uncheckable when it substitutes for dose clarity and relevant evidence. FTC health products compliance guidance FDA 101 dietary supplements
Why broad wording causes trouble
A broad wellness phrase can be accurate in one context and misleading in another, and it never identifies which ingredient is responsible for which outcome. FTC health products compliance guidance FDA supplement claim substantiation guidance
When a label claims an outcome and hides the individual amounts, the weight shifts off the evidence and onto the copywriting. FDA dietary supplement labeling guide FDA 101 dietary supplements
Copy can sound precise while the evidence stays vague
Names, forms, doses, and relevant evidence make claims checkable. Polished copy without those details remains vague when checked line by line.
Until the dose table catches up with the promise, treat the product as marketing first. FDA dietary supplement labeling guide FDA supplement claim substantiation guidance FTC health products compliance guidance
What to check on the label
Claim match
Map each claim to a specific ingredient and dose instead of accepting a broad outcome sentence.
Dose gate
Read the per-serving amount before deciding what the formula is likely to do.
Evidence gate
Reject health claims that stay vague about study type, ingredient, and claim boundary.
