How to evaluate supplement safety in 2026
Understanding the regulatory landscape is your first defence. In the UK, supplements are regulated as food products rather than medicines, which means manufacturers face less stringent testing requirements. This creates significant safety gaps that savvy consumers must navigate independently.
Start by checking dosage levels against established Tolerable Upper Intake Levels (ULs) set by the European Food Safety Authority. These limits represent the maximum daily intake unlikely to cause adverse health effects. The supplement market is one of the more unregulated industries, enabling false claims and questionable sponsored content to deceive even careful consumers.

Be wary of health claims that sound too good to be true. Marketing tactics on social media often exaggerate benefits whilst downplaying risks. Phrases like
