The Claim

The absence of mandatory pre-market quality control for dietary supplements necessitates ongoing monitoring and potential legal tightening of regulatory requirements.

Description
1 study reviewed
In plain English

Dietary supplements are not required to undergo quality testing before being sold, so regulatory agencies should continue to monitor them and consider strengthening legal standards.

See the scientific wording

Due to the lack of mandatory pre-market quality control for dietary supplements, ongoing monitoring and potential tightening of legal requirements are recommended.

Why this might work

Without mandatory testing before sale, harmful substances in dietary supplements can be swallowed and absorbed into the bloodstream, where they circulate and accumulate in tissues.

  1. Study: Analysis of mercury content in fish and its impact on human health in the context of omega-3 and omega-6 fatty acid (DHA, EPA) supplementation derived from fish oil

    Even though the fish oil pills tested didn't have too much mercury, the study says we can't trust they're always safe because no one checks them before they're sold. So experts say we should keep checking them and maybe make stronger rules.
