A study led by Rajesh Narendran of the Department of Radiology, University of Pittsburgh, Pittsburgh, Pennsylvania, found that taking Omega-3 fatty acids (fish oil supplements) could help to improve working memory in healthy young adults ages 18-25. The study titled “Improved Working Memory but No Effect on Striatal Vesicular Monoamine Transporter Type 2 after Omega-3 Polyunsaturated Fatty Acid Supplementation” is being published this week in the journal PLOS One.
The team of researchers used samples collected from a group of healthy young men and women. All participants were given Omega-3 fatty acids (fish oil supplements) for a span of 6 months.
Before the study started, all participants were measured by using two methods, (1) memory test known as positron emission tomography (PET) such as remembering sequences of numbers and letters and (2) blood test. As researchers returned to collect results after six months, they found that all samples have improved in their working memory.
