DHA supplementation (600 mg/day for 16 weeks) significantly increases sleep duration and reduces night wakings in children.
For children with sleep issues, consider a DHA supplement of 600 mg per day for at least 16 weeks. This has been shown in an RCT to increase total sleep time by nearly an hour and reduce night wakings.
GoodSupportsHIGH confidence
In their subsequent randomized controlled trial (RCT) of DHA supplementation (with 600 mg/day for 16 weeks), significant group differences were observed including sleep duration increased by 58 min and fewer and shorter night-wakings in the treatment group versus the placebo group [50].
Why this rating
Based on a randomized controlled trial (RCT), which is higher quality than observational studies.
