Tonight, I just stumbled upon yet another potential quick fix in a cross-over placebo controlled study published early online in Nutrition Journal in which the authors concluded that fish improved cognitive performance in healthy adults in just 5 short weeks compared to placebo. They reached their conclusion by offering 3g/d of fish oil to 40 healthy middle-aged to elderly participants 51-72yo w/body mass index 20-30kg/m2 for 5 weeks, followed by a 5 week washout period in a randomized fashion.
For those of you interested in improving your cognitive function in just over a month by replicating this study, the participants took 5 capsules of fish oil daily which contained a total of 1,500mg EPA & 1050mg DHA along w/450mg unspecified omega 3 fatty acids. Realize that your average 1g dose of fish oily is not nearly as concentrated and contains just 180mg EPA + 120mg DHA, so you'd need 8+ capsules to get an equivalent amount of EPA & DHA. Think about that when you purchase your next bottle of fish oil!
