The Claim

The interaction between B vitamins and omega-3 fatty acids in slowing cognitive decline in mild cognitive impairment may be mechanistically linked to the role of B vitamins in methylating phosphatidylethanolamine to form phosphatidylcholine, a phospholipid enriched in omega-3 fatty acids that supports brain structure and synaptic function.

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.

How it works
1 study reviewed
In plain English

Some scientists think that taking B vitamins and omega-3s together might help slow memory loss in people with early memory problems, because B vitamins help turn one type of fat in the brain into another that’s full of omega-3s and helps brain cells communicate better.

What the research says

  1. Study: Beneficial Interactions Between B Vitamins and Omega‐3 Fatty Acids in the Prevention of Brain Atrophy and of Cognitive Decline in Early Stage Alzheimer's Disease

    The study found that B vitamins only helped slow memory loss in older adults who already had high levels of omega-3 fatty acids in their blood. The researchers think this is because B vitamins help turn a brain fat called phosphatidylethanolamine into another one, phosphatidylcholine, which is rich in omega-3s and helps brain cells communicate better.
