Omega-3s enhance sleep qualityEffect of Docosahexaenoic Acid and Eicosapentaenoic Acid Supplementation on Sleep Quality in Healthy Subjects: A Randomized, Double-Blinded, Placebo-Controlled Trial.
Study shows significant improvements
We investigated how omega-3 fatty acids, specifically DHA and EPA, affect sleep quality in adults aged 45 and older. Our study involved 66 healthy participants and employed a randomized, double-blind, placebo-controlled design for 12 weeks.
Participants in the DHA/EPA group showed significant improvements in sleep quality metrics, including less frequent dreaming and better sleep efficiency compared to those taking a placebo. This is notable as it provides new insights about the beneficial effects of omega-3s on sleep in an older demographic.

DHA levels linked to OSA severityMembrane level of omega-3 docosahexaenoic acid is associated with severity of obstructive sleep apnea.
Moderate relevance, not isolated
We investigated how the omega-3 fatty acid docosahexaenoic acid (DHA) impacts the severity of obstructive sleep apnea (OSA) in 350 patients undergoing sleep studies. Our study aimed to determine if there is a relationship between the levels of DHA in red blood cells (RBC) and the severity of sleep apnea, categorized as none/mild, moderate, or severe based on apnea hypopnea index (AHI) scores.
Our findings revealed that lower levels of DHA are linked to more severe cases of OSA. For each standard deviation increase in DHA, patients were about 50% less likely to be classified in the severe apnea category. Specifically, we noted decreased odds of falling into the severe OSA group when DHA levels were higher, suggesting that DHA may play an important role in the severity of this condition.
These insights imply that maintaining healthy DHA levels could potentially influence OSA severity and could aid in developing treatment strategies. We believe that future research should explore the potential benefits of DHA supplementation for those suffering from sleep apnea.

We explored the relationship between omega-3 fatty acid docosahexaenoic acid (DHA) and the severity of obstructive sleep apnea (OSA) in 350 patients. Our findings revealed that higher levels of DHA in red blood cells were associated with a lower likelihood of severe OSA.
Specifically, those with increased DHA levels were about 50% less likely to fall into the severe OSA category. This suggests that DHA might play a role in the severity of sleep apnea, opening doors for deeper research into DHA supplementation as a potential treatment option.
