Organic, vegan and other certifications explained

Organic (EU organic leaf, Soil Association, USDA Organic). Audited certification covering how agricultural ingredients are grown and processed. It says nothing about dose, purity testing or efficacy.

Vegan marks. Registered vegan trademarks audit the supply chain, including capsule material and processing aids. An unregistered "vegan" claim on the label is a self-declaration.

GMP (Good Manufacturing Practice). A manufacturing standard covering hygiene, documentation and batch control. In the EU and UK, food supplement manufacture is regulated regardless; a specific GMP certificate names the auditing body.

Allergen-free claims. "Free from" claims are only meaningful where the brand states whether it means formulated-without or tested-below-a-threshold in a dedicated facility.

Sustainability marks for fish oil. Marine stewardship and friend-of-the-sea style marks address sourcing, not purity. Purity is a separate oxidation and contaminant test.
