The 4 Essential Nutrients to Improve Cognitive Health

The brain is an extremely important organ in the body that has an impact on much more than just allowing you to think. It is the body's control center and plays a role in keeping your heart beating, getting air to your lungs, regulating hunger, keeping your memory sharp, and so much more. 


Supporting your brain through adequate nutrients is key to improving concentration, mental health, focus, and memory. Some essential nutrients to include in your eating pattern to support cognitive health are antioxidants, omega-3 fatty acids, B vitamins, and vitamin E. 


Some of these nutrients help increase blood flow to the brain, help improve cell connections, limit oxidation, or reduce inflammation, all of which help the brain function optimally!


The Best Foods and Nutrients That Support Brain Heath



Various antioxidants can be found in many fruits and vegetables. Antioxidants help fight free radicals, which cause cell damage. They also have anti-inflammatory properties. 


Oxidative stress and inflammation can both contribute to neurodegenerative diseases and cognitive decline. Studies suggest that certain antioxidants can help slow cognitive decline and improve cognitive health in older adults because of their ability to fight free radicals and reduce inflammation.2


Food sources of antioxidants:


  • Blueberries
  • Kale
  • Dark Chocolate




Omega-3 fatty acids are widely known for their neuroprotective properties. The brain is largely comprised of fatty acids, and it specifically uses omega-3 fatty acids to build brain and nerve cells. They are also key to developing healthy cell membranes, which help facilitate communication between cells. This, in turn, supports memory and much more. Additionally, omega-3 fatty acids may help slow age-related cognitive decline and potentially prevent Alzheimer’s disease.  


Food sources of omega-3 fatty acids:


  • Salmon
  • Walnuts
  • Flaxseed



B Vitamins:

In total, there are eight B vitamins. While each serves a special purpose, their most known role is aiding metabolism, which directly impacts energy levels, cell metabolism, and brain function. B vitamins also have neuroprotective effects that can help with cognitive performance. 


Research has shown that getting B vitamins through dietary intake was associated with improved processing speed, recall, recognition, and verbal ability.4 Folate, specifically, has been shown to help minimize age-related decline.  


Food sources of B vitamins:


  • Beef
  • Legumes
  • Eggs



Vitamin E:

Vitamin E is special because it also has antioxidant properties, fighting against free radicals. Because of this, vitamin E has been shown to benefit your health in a variety of ways. Positive correlations have been made between higher intakes of vitamin E and a lower risk of Alzheimer’s disease.5 Vitamin E has also been shown to promote healthy brain aging and delay cognitive decline. 


Food sources of vitamin E:


  • Almonds
  • Hazelnuts
  • Sunflower seeds



When it comes to supporting your cognitive health, the food you eat has a huge impact! Make sure you are incorporating foods with antioxidants, omega-3s, B vitamins, and vitamin E in your eating pattern to support your brain’s health.
