What Can Advertisers Learn from This Season’s Hot Topics?

From pharma and supplements, to pet products and AI, the same rule applies: advertisers need evidence that matches the claims.

In the Season 6 finale of Ad Watchers, attorneys from the National Advertising Division (NAD) revisit some of the season’s hottest advertising topics and examine a new round of cases involving pharmaceutical products, GLP-1 weight loss programs, supplements, contact lenses, pet products, and AI-enabled technology.

The episode highlights six recurring principles:

Tailor claims to the evidence. Don’t make broader claims than your data supports.

Substantiate health claims with reliable science. Health and wellness claims require appropriate scientific support.

Context matters. Even promotional language can become an objective, measurable claim requiring evidence.

Truthful claims can still mislead. NAD looks at the overall consumer takeaway, not just whether individual words are technically accurate.

AI claims need AI-specific proof. Evidence must support what the technology itself can actually do, not just broader outcomes associated with its use.

The season finale offers advertisers practical examples of what is—and is not—working when NAD evaluates advertising claims across rapidly evolving industries.
