The UK's Advertising Standards Authority (ASA) has upheld two complaints against Higham Miller Coffee Ltd, trading as Exhale Coffee, after ruling that a paid Instagram advert made unauthorised health and nutrition claims linking the brand's coffee to telomere protection, slowed cellular ageing and extended lifespan.
The ad, which ran in February of this year, featured Exhale's founder describing telomere shortening as a predictor of lifespan and citing an observational study of NHS nurses to suggest moderate coffee drinkers had "telomeres equivalent to people five years younger."
It attributed this to polyphenols, which the company said its roasting process was designed to preserve.
The ASA found these were specific health claims not authorised on the GB Nutrition and Health Claims (NHC) Register.
While polyphenols carry one approved claim relating to protecting blood lipids from oxidative stress, that claim applies only to olive oil, not coffee — plus, it was not referenced in the ad regardless.
General claims such as "amazing health benefits" and support for "gut and brain health" were also judged non-compliant, since UK rules require general health claims to be paired with an authorised specific claim.
Exhale's argument that magnesium and potassium content in a two-cup serving met thresholds for authorised nutrient claims did not hold, as those claims never appeared in the ad itself.
A second breach concerned Dr Rupy, founder of The Doctor's Kitchen and Exhale's Chief Science Officer, whose involvement in testing was read by the ASA as an implied professional endorsement — impermissible under CAP Code rule 15.6.3.
Exhale confirmed the ad was no longer running and said it would amend future advertising accordingly.
For those riding the longevity wave, the ruling reinforces a now-familiar regulatory line: peer-reviewed evidence, however credible, does not substitute for formal authorisation under the GB NHC Register.
Marketing teams building claims around polyphenols, antioxidants or biological ageing markers should treat pre-authorisation checks as non-negotiable before campaigns go live.
