Omega-3 fatty acids, specifically eicosapentaenoic acid (EPA)-rich fish oil, improved mental processing speed and visual brain activity in healthy adults. This suggests enhanced neural recovery in visual pathways following stimulation.

Area of Science:

  • Neuroscience
  • Nutritional Science
  • Ophthalmology

Background:

  • Dietary omega-3 fatty acids, like docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), are known for cardiovascular and mood benefits.
  • Direct neurophysiological evidence of omega-3s' effects on cortical activity, particularly visual processing, remains limited.
  • Nonlinear multifocal visual evoked potentials (mfVEP) offer a sensitive measure of neural recovery dynamics after stimulation.

Purpose of the Study:

  • To investigate the impact of EPA-rich versus DHA-rich fish oil supplementation on mental processing speed.
  • To examine the effects of different omega-3 fatty acid ratios on visual evoked brain activity using nonlinear mfVEP.
  • To explore potential neurophysiological mechanisms underlying omega-3s' influence on cortical function.

  • A double-blind, crossover study with 22 healthy young adults.
  • Participants received either EPA-rich or DHA-rich fish oil for 30 days, followed by a 30-day washout, then the other supplement.
  • Measurements included psychophysical choice reaction times and nonlinear multifocal visual evoked potential (VEP) testing at baseline and post-supplementation.

Main Results:

  • EPA-rich supplementation significantly reduced the amplitude of a specific VEP kernel component related to the magnocellular visual pathway.
  • Significantly faster choice reaction times were observed with EPA-rich, but not DHA-rich, supplementation compared to baseline.
  • Correlations between VEP components differed between EPA-rich and DHA-rich diets, suggesting distinct neurophysiological effects.

Conclusions:

  • EPA-rich omega-3 supplementation enhances mental processing speed and alters visual cortical activity, particularly in magnocellular pathways.
  • The observed reduction in VEP nonlinearities suggests improved neural recovery efficiency in the visual system after cortical activation.
  • Findings provide direct neurophysiological evidence for the cognitive and visual processing benefits of EPA-dominant omega-3s.
