The Claim
Among older adults with mild cognitive impairment, docosahexaenoic acid (DHA) significantly enhances the efficacy of B vitamins in slowing cognitive decline, particularly improving verbal memory and global cognition, whereas eicosapentaenoic acid (EPA) shows similar but non-significant trends.
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.
For older people with mild memory problems, taking DHA (a type of omega-3 from fish) might make B vitamins work better to help with memory and thinking, while EPA (another omega-3) seems to help a little but not enough to be sure.
See the scientific wording
Among older adults with mild cognitive impairment, docosahexaenoic acid (DHA) is a more potent modifier of B vitamin efficacy on cognitive decline than eicosapentaenoic acid (EPA), with DHA showing significant interactions on verbal memory and global cognition, while EPA showed similar but non-significant trends.
What the research says
1 studyThis study found that older adults with memory problems who had more DHA (a type of omega-3 fat) in their blood benefited much more from B vitamins than those with less DHA. EPA, another omega-3, didn’t show the same strong benefit.
