In a randomized, double-blind, placebo-controlled trial, 362 healthy children with no significant learning difficulty but below-average literacy skills were allocated to take 600 mg of algal DHA daily or placebo for 16 weeks.
There were two measures of sleep quality: a questionnaire and sleep actigraphy, with the latter only being performed for 43 participants. On the questionnaire, there was no difference in any measures of sleep quality, though with sleep actigraphy, there was a statistically significant improvement in sleep efficiency, with fewer wake episodes in the intervention group, and more sleep overall.
