The Claim
The bioavailability of omega-3 fatty acids in fish oil supplements is influenced by their molecular form, with free fatty acids exhibiting higher bioavailability compared to triglycerides, and ethyl esters demonstrating the lowest bioavailability in humans.
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.
Your body absorbs omega-3s from fish oil better depending on the form they're in — free fatty acids are easiest to absorb, triglycerides are okay, and ethyl esters are the hardest.
See the scientific wording
The bioavailability of omega-3 fatty acids in fish oil supplements varies depending on their molecular form, with free fatty acids showing higher bioavailability than triglycerides, and ethyl esters showing the lowest bioavailability in humans.
What the research says
1 studyThe study says that how your body absorbs omega-3s from fish oil depends on the form it's in, and that free fatty acids are absorbed best, then triglycerides, and ethyl esters the worst—just like the claim says.
