The Claim
Commercially available fish oil supplements contain mercury levels that are below the regulatory limits established for food, dietary supplements, and medicinal products.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Fish oil supplements sold in stores have mercury levels that are lower than the safety limits set by regulators for food, supplements, and medicines.
See the scientific wording
Commercially available fish oil supplements typically contain mercury levels below regulatory limits established for food, dietary supplements, and medicinal products.
When fish are processed into oil, the mercury stays behind in the solid parts, and the oil is cleaned through filtering and distillation so it ends up with almost no mercury.
What the research says
1 studyMost fish oil pills sold in stores have very little mercury—less than what health agencies say is safe. So, they’re generally okay to take.
