‘Unacceptable’ prostate supplement adverts banned

Ads for four supplement brands banned over misleading health claims

Adverts promoting prostate supplements and home-testing kits have been banned after regulators ruled they could mislead vulnerable consumers.

The Advertising Standards Authority (ASA) took action against campaigns by Nutrisslim, Nutreance, Muxue Trade, and Impact Herbs, which made unauthorised claims that their products could treat medical issues such as enlarged prostate, prostate inflammation, or urinary flow problems.

According to the ASA, many of the claims found in the ads were “unacceptable,” breached multiple advertising rules, and potentially discouraged people from seeking proper medical advice. None of the supplements involved are licensed medicines, and food products—including supplements—are prohibited from making medicinal claims.

The regulator also banned adverts from two companies selling home-testing kits, Lifelab Testing and Self Check, for implying that prostate-specific antigen (PSA) tests could diagnose or rule out prostate cancer. A PSA test alone cannot make such determinations, and the ads failed to clearly state the limitations of the tests.

The ASA warned that “misleading ads about prostate supplements or tests can cause real harm.”

Amy Rylance of Prostate Cancer UK welcomed the rulings, saying the charity was “pleased to see the ASA getting proactive in identifying and banning these dangerous and misleading adverts.” She emphasised that no evidence exists to show supplements can treat or prevent prostate issues and urged anyone concerned about prostate health to consult a doctor.

How the companies responded

• Nutreance (Top 5 Supplements) argued that its ads did not claim to treat or cure any disease and did not reference specific medical conditions.

• Nutrisslim (Nature’s Finest) said its claims were based on botanical ingredients and believed they were permissible. The company said it had removed images of doctors and references such as “doctor-formulated” from its website.

• Self Check stated that its products meet CE certification requirements and include disclaimers advising customers to consult a GP. It also removed the word “cancer” from its Google ad listings.

• Lifelab Testing said its tests were properly CE marked and that the banned ads had been taken down and would not be used again.

• Muxue Trade and Impact Herbs (Impact Supps) did not respond to the ASA.
