The Claim

Optimal brain health outcomes require the simultaneous presence of adequate levels of omega-3 fatty acids and low plasma homocysteine concentrations, which indicate sufficient B vitamin status.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

How it works
2 studies reviewed
In plain English

To keep your brain working its best, you need enough omega-3s (found in fish and nuts) and low levels of a substance called homocysteine, which means you're getting enough B vitamins from your diet.

See the scientific wording

Optimal brain health outcomes require simultaneously adequate levels of omega-3 fatty acids and low plasma homocysteine (indicative of sufficient B vitamin status).

What the research says

2 studies
  1. Study: Brain atrophy in cognitively impaired elderly: the importance of long-chain ω-3 fatty acids and B vitamin status in a randomized controlled trial.

    The study found that B vitamins only helped protect the brain from shrinking if people already had enough omega-3 fatty acids, and omega-3s only worked well if B vitamins were also sufficient. So both are needed together for the best brain health.

  2. Study: A combination of omega-3 fatty acids, folic acid and B-group vitamins is superior at lowering homocysteine than omega-3 alone: A meta-analysis.

    This study shows that taking omega-3s along with B vitamins lowers a harmful blood chemical (homocysteine) better than taking omega-3s alone. Since low homocysteine is good for the brain, this supports the idea that you need both omega-3s and B vitamins together for the best brain health.
