Why it matters
Fish oil can contain environmental loads like mercury, PCBs and dioxins. Purified oil with proven low values is safer. Declaration alone is not enough — independent CoAs build trust.
How MVS checks it
MVS reports heavy metals, PCBs and dioxins per batch where publicly available — linked to CoA sources.
