A consumer group investigation found that several omega-3 supplements labeled as 'high strength' contain significantly less EPA and DHA than claimed, often costing consumers twice as much as cheaper alternatives. Which? tested 24 products against the Scientific Advisory Committee on Nutrition (SACN) guidelines, which recommend 450mg of EPA and DHA daily. Despite being marketed as 'high strength,' products from Superdrug, Morrisons, Sainsbury’s, and Holland & Barrett contained only 250-375mg combined, falling short of the recommended dose. Retailers defend their labeling as compliant with regulations, citing EU standards that permit claims if products meet minimum thresholds (80mg EPA/DHA).
