The Claim
The unit price of fish oil products in China is not significantly correlated with oxidation levels (measured by peroxide or anisidine values) or heavy metal contamination, indicating that price cannot serve as a reliable indicator of product quality.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In China, more expensive fish oil supplements are not consistently cleaner or safer than cheaper ones, as price does not reliably reflect how oxidized the oil is or whether it contains harmful metals.
See the scientific wording
The unit price of fish oil products in China shows no significant correlation with oxidation levels (peroxide or anisidine values) or heavy metal contamination, meaning consumers cannot use price as a reliable indicator of product quality.
What the research says
1 studyThe study found that expensive fish oil supplements in China aren’t necessarily better or safer than cheaper ones — some pricey ones were just as oxidized or contaminated as cheap ones. So, you can’t tell if fish oil is good just by how much it costs.
