Fish Oil & Brain Benefits

The Amazing Brain-Boosting Effects of Omega-3 Fish Oil for Healing and Recovery


If you are suffering from neurological symptoms, there are many areas to focus on during the healing and recovery process. Diet and nutrition is a key component and in this blog we dive a little deeper into one aspect; fish oil. This blog will give a brief overview of why fish oil is key for brain health, brain benefits after taking fish oil, and how to correctly implement fish oil into your daily routine. Let’s break it all down.

Fish Oil can improve brain function!

After sustaining a brain injury, people may experience a wide variety of neurological symptoms. Some common examples are headaches, dizziness, disorientation, cognitive impairment including memory, concentration, and speaking difficulties, blurry vision, fatigue, sensitivity to light/sounds, and difficulty sleeping.

While these symptoms are still causing problems, many patients look into the area of diet and nutrition to help them in their recovery. Our objective in this blog is to provide information that will help you understand why fish oil is a critical component of brain healing and overall brain health.

Why fish oil?

The brain needs fatty acids in order to function properly. The most important are called omega 3 fatty acids, namely eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Fish oil has high concentrations of both EPA and DHA.

We believe DHA is the most important fatty acid and is "king" in healing the brain after recovery. DHA makes up 97% of the omega-3's found in the brain. DHA is a structural component in the cortex, which is involved in executive functioning tasks like language, memory, creativity, emotion, and attention. It also helps in neuron communication and supports optimal neurotransmitter levels.

One study showed that high levels of DHA were reported to decrease the probability of developing dementia by 47% and Alzheimer's by 39%!

Fish Oil Reduces Brain Inflammation

After sustaining a brain injury, oxidative stress can occur and result in inflammation and damage to the structure of brain cells. This can be the reason why people experience the symptoms listed above.

Omega 3's have shown to significantly reduce the inflammatory response in the brain after it is injured. EPA and DHA help restore brain function and protect against oxidative stress. EPA is better at reducing inflammation than DHA, which is why we commonly encourage people to find a supplement that contains both EPA and DHA.

Fish Oil Improves Brain Communication

DHA improves neuroplasticity and neurogenesis in the brain, Neuroplasticity is the ability of the brain to rewire itself and change, while neurogenesis is the brain's ability to create new neurons and connections between neurons. These are both critically important in properly healing the brain after injury.
