ASA Enforcement Reports on ADHD, autism and prostate supplement ads
CAP News (15 October 2026) announces two ASA Enforcement Reports on misleading health ads. Ad volumes fell in both supplement sectors, but compliance stayed low.
What has been published
In a CAP News item dated 15 October 2026, the ASA announced that it was releasing two Enforcement Reports on misleading health-related advertising.
The first report looks at food supplement ads that claim to prevent, treat or cure traits associated with ADHD and autism spectrum disorder (ASD). The second examines the irresponsible advertising of prostate supplements and Prostate-Specific Antigen (PSA) home testing kits.
ADHD and autism supplement ads
According to the ASA, enforcement action aimed at Meta and Google has led to a significant drop in the amount of harmful advertising in this area. Even so, the level of compliance is still low.
The ASA says this points to a continuing need to keep monitoring the sector, to enforce further, and to work with platforms so that vulnerable audiences are protected.
Prostate supplements and PSA home testing kits
The ASA describes the results of this second report as mixed.
The number of prostate supplement ads fell considerably, yet compliance among those ads stayed extremely low. The picture for PSA home testing kits was different: after targeted action, advertisers of these kits became more compliant.
What the ASA says it will do next
The ASA states that it will keep both sectors under watch. Where it considers it necessary, it intends to take additional action against misleading health claims, with the aim of safeguarding consumers.
