A recent study has now claimed that fish oil does not help brain function. The researchers took 700 men and women in their 70’s and randomly assigned them to take a total of 500 mgs of fish oil or olive oil for two years. They then tested their cognitive function at the end of the two-year period. They did not find a difference. Therefore, they concluded that fish oil does not provide improvement in cognitive function in the elderly.

That all makes perfect sense, right? I beg to differ. Most of the studies showing benefit of fish oil, especially when it comes to the heart used 1000 mgs of fish oil not 500 mgs. In addition, it may take more than 24 months to show a difference.

One of the things that cause public dismay is the conflicting advice that continues to be published in the media. This is especially an issue when it comes to supplements. If the wrong dose is used or the incorrect formulation, then the study results may not be valid.

I would hate to see my patients giving up taking their fish oil when it has so many benefits. It is good for lowering triglycerides, it is good for the heart, mood, skin and joints, and I believe in the proper dosage it is also good for cognitive function.
