IFOS, or International Fish Oil Standards, is a non-profit organization dedicated to the assessment and certification of the quality of fish oil supplements. IFOS was founded in 2003 and has members from around the world, including producers, processors, researchers, and consumers of fish oil supplements.

IFOS has developed a quality standard for fish oil supplements, known as the "IFOS Omega-3 Index". This standard sets the minimum requirements that fish oil supplements must meet to be certified by IFOS.

The requirements of the IFOS Omega-3 Index include:

- The product has PCB levels below 50% according to WHO and CRN standards.
