Our Standards

Quality you can choose with confidence. We select sports nutrition for the UK training community using independent certification from LGC’s Informed programmes. Informed Sport and Informed Choice provide banned-substance screening; Informed Protein verifies protein content and label accuracy.

Look for the relevant badge on each product. Each programme has its own testing standards, backed by LGC’s expertise in laboratory analysis and quality assurance.

Informed Sport

Every batch tested before release. Certified products undergo banned-substance testing, a review of manufacturing quality systems and ongoing blind testing. Designed for athletes who need confidence in what they take, the programme helps reduce the risk of prohibited-substance contamination.

Informed Choice

Ongoing banned-substance monitoring. Certified products are regularly bought from retailers and tested through monthly blind sampling, with at least one batch tested each month. This provides continuing oversight of products available to everyday active consumers.

Informed Protein

Confidence in the protein on the label. Regular testing verifies declared protein amounts and checks for amino spiking or other nitrogen-rich adulterants that could inflate protein claims. Certification also includes a review of manufacturing quality controls.

Certification applies to the specific product and programme shown, rather than every product from a brand. If you compete under anti-doping rules, check your product and batch directly with SIV under 'Certification' for each product with a verification link to official Informed Sport directory
