The Claim
The percentage of re-esterified triglycerides (rTG) in fish oil supplements is a key determinant of omega-3 fatty acid incorporation into human cell membranes, such that formulations containing more than 95% rTG result in significantly higher erythrocyte eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) levels after 16 weeks compared to formulations with less than 70% rTG, indicating that rTG content should be considered a quality marker for bioavailability.
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.
Fish oil supplements with over 95% re-esterified triglycerides (a type of fat form) seem to get more omega-3s into your blood cells after 16 weeks than those with less than 70%, so this might be a good sign of a better-quality supplement.
See the scientific wording
The percentage of re-esterified triglycerides in fish oil supplements is a key determinant of omega-3 fatty acid incorporation into human cell membranes, with formulations containing >95% rTG leading to significantly higher erythrocyte EPA and DHA levels after 16 weeks compared to those with <70% rTG, suggesting rTG content should be considered a quality marker for bioavailability.
What the research says
1 studyThe study found that fish oil with more re-esterified triglycerides led to higher levels of healthy omega-3s in red blood cells after 16 weeks, just like the claim says.
