The Claim
In older adults with mild cognitive impairment, the cognitive benefits of B vitamin supplementation on verbal memory are sustained over time only in individuals with high baseline docosahexaenoic acid (DHA) levels, resulting in a 0.46-point annual improvement compared to no change in placebo or low-DHA groups.
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 B vitamins might help their memory get better over time—but only if they already have high levels of a certain omega-3 fat called DHA. If they don’t, the vitamins don’t seem to help.

What the research says
1 studyB vitamins only help older adults with memory problems if they already have enough omega-3s (like DHA) in their blood — otherwise, the vitamins don’t help. Think of DHA as the key that unlocks the benefit of the vitamins.
