The Claim
Among 16 commercially available fish oil supplements sold in the United States, 6 out of 15 products contained EPA levels differing by more than 20% from their labeled amounts, and 10 out of 15 contained DHA levels differing by more than 20% from their labeled amounts, indicating widespread inaccuracies in omega-3 fatty acid content labeling.
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.
Testing of 15 fish oil supplements sold in the U.S. found that some contained EPA or DHA levels that were more than 20% higher or lower than what was stated on the label, suggesting that label claims for these nutrients are often inaccurate.

What the research says
1 studyStudy: The Quantitation of EPA and DHA in Fish Oil Dietary Supplements Sold in the United States
Scientists tested 15 fish oil pills bought in U.S. stores and found that many didn’t have the amount of healthy fats (EPA and DHA) listed on the label—some had way more, some had way less. This means the labels can’t be trusted.
