Marine lipids, particularly omega-3 polyunsaturated fatty acids (PUFAs) such as EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), have been studied for their potential role in supporting sleep quality and treating insomnia. The scientific rationale is based on the involvement of omega-3 fatty acids in regulating neurotransmitter function, reducing inflammation, and supporting brain health—all factors that may indirectly influence sleep patterns. Several observational studies have reported associations between higher dietary intake or blood levels of omega-3s and better sleep quality, including increased sleep duration and reduced incidence of sleep disturbances. A few randomized controlled trials (RCTs) in children and adults suggest that omega-3 supplementation may improve certain sleep parameters, such as sleep efficiency and latency. For example, a 2014 RCT by Montgomery et al. found that DHA supplementation improved sleep in children, while some studies in adults have noted modest benefits in subjective sleep quality.

However, while these findings are promising, the body of evidence remains limited by small sample sizes, variations in study design, and inconsistent results. Meta-analyses to date indicate that, although there may be a positive effect, it is generally modest and not universally observed across all populations. Therefore, marine lipids are considered to have some scientific basis for supporting sleep and potentially treating mild insomnia, but the strength of evidence is moderate at best, justifying an evidence rating of 2 out of 5.
