The Claim
Higher baseline plasma levels of docosahexaenoic acid (DHA) significantly enhance the cognitive benefits of B vitamin supplementation in older adults with mild cognitive impairment, with stronger effects observed for DHA than for eicosapentaenoic acid (EPA), which showed a similar but non-significant trend.
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.
If you're an older adult with mild memory problems, having more DHA (a type of omega-3 found in fish) in your blood might make B vitamins work better to help your brain, and DHA seems to help more than another omega-3 called EPA.
See the scientific wording
Higher baseline plasma levels of docosahexaenoic acid (DHA), a key omega-3 fatty acid, significantly enhance the cognitive benefits of B vitamin supplementation in older adults with mild cognitive impairment, with stronger effects observed for DHA than for eicosapentaenoic acid (EPA), which showed a similar but non-significant trend.
What the research says
1 studyWhen older adults with memory problems take B vitamins, they do better only if they already have enough DHA (a healthy fat found in fish). The more DHA they had at the start, the more the B vitamins helped their memory and thinking—better than EPA, another similar fat.
