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 a test of 47 fish oil supplements sold in New Zealand, 91% had EPA and DHA concentrations that were within 90% of what was printed on the label when measured using standard laboratory methods.
