Fish for Thought: Omega-3 Fatty Acids and Your Brain

While most of us know to grab a helmet before hitting the ski-slopes, or the importance of keeping the mind sharp by challenging the brain, our Western diet generally lacks the necessary omega-3 intake for optimal brain function. In fact, an estimated 70% of the population is deficient in this essential fatty acid.

The Research

Known primarily for its cardiovascular benefits, new research has brought to light the incredible benefits of omega-3s for your brain. Thanks to these ground-breaking studies, we now know that omega-3 lipids make up approximately 8% of the brain’s weight, and exert profound effects on your brain’s size, structure, and function. In particular, studies have shown remarkable improvements in participant cognition and memory, mental health, and Alzheimer’s prevention.

Proven cognitive benefits of omega-3 supplementation include:

  • ADHD
  • anxiety
  • aggression
  • bipolar disorder
  • cognition in the elderly
  • decreased risk of dementia
  • depression
  • memory
  • mood and well-being
  • reaction time
  • stress
  • stroke (preventative & therapeutic)

It is also worth noting that omega-3 fatty acids lower your risk of major chronic illnesses such as heart disease, cancer, and arthritis.

The ideal dosage ranges from 1,000-3,000 mg of EPA and 1,000-1,500 mg of DHA daily for optimal results.

A Word on Supplements

While omega-3s are present in some foods, fish offers the highest source by far. The vast majority of people simply do not consume enough of these fatty acids in their diet. Often, the best and perhaps easiest alternative is a good quality supplement. It is important to remember that not all supplements are created equal. Many fish oils are contaminated, oxidized, or made with poor-quality ingredients, and have the potential to cause health problems instead of solving them.

Our Recommendation

We highly recommend taking an all-natural fish oil that has been tested to be free of contaminants by a third-party lab. At our clinic, we supply our patients with the OmegaGenics EPA-DHA line, which is also gluten-free, sourced from cold-water fish, and stabilized with antioxidants.
