A report released by the consumer advocacy group Which? has raised concerns regarding the labeling accuracy of omega-3 supplements marketed as 'high strength.' After testing 24 different products, researchers discovered that many supplements failed to meet the concentrations of EPA and DHA—the primary active fatty acids—claimed on their packaging.

The investigation measured these products against the Scientific Advisory Committee on Nutrition (SACN) guidance, which provides benchmarks for nutritional intake. The findings suggest a potential gap between consumer expectations and the actual chemical composition of these health products. While the report highlights that some products are significantly lower in potency than advertised, it does not suggest that the supplements are inherently dangerous, but rather that they may be misleading to consumers who rely on label claims to manage their nutritional intake.

This report serves as a critique of current industry labeling standards, suggesting that 'high strength' is often used as a marketing term rather than a strictly regulated nutritional descriptor. As of now, the industry response to these specific findings has been limited, and the report has prompted calls for more rigorous oversight of the supplement market to ensure that product labels accurately reflect the contents of the capsules.
