The Claim
In older adults with mild cognitive impairment, B vitamin supplementation has no significant effect on cognitive decline when baseline plasma omega-3 fatty acid levels are low, indicating that omega-3 status is a necessary precondition for B vitamins to exert cognitive benefits.
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 and your body doesn't have enough omega-3s, taking B vitamins won't help your memory get better. But if you do have enough omega-3s, B vitamins might help.

What the research says
1 studyB vitamins only help slow memory loss in older adults if they already have enough omega-3 fatty acids in their blood; if omega-3 levels are low, the vitamins don’t help at all.
