Omega-3 fatty acids, particularly EPA and DHA, are essential nutrients that may support sleep quality. These fats are commonly found in fatty fish and are taken as supplements to enhance sleep efficiency and reduce sleep latency. DHA is believed to aid melatonin synthesis, while EPA can help regulate serotonin, both important for healthy sleep patterns.
How it works: Scientific evidence suggests that Omega-3s can improve sleep by influencing neurochemical pathways and circadian regulation. DHA’s role in melatonin production is particularly relevant, potentially helping normalise sleep cycles. EPA’s impact on serotonin may also support mood and sleep quality.

Final verdict: For those with sleep difficulties, particularly if nutrient deficiency is suspected, taking 1-2 grams daily of combined EPA/DHA in a 2:1 ratio with evening meals is a practical approach. It’s generally safe with minimal side effects, though consistency is key. Dietary sources include salmon, sardines, mackerel, trout, and herring. Supplements may be considered if these are not regularly consumed.
Natural Sources:
Eating fatty fish like salmon or mackerel 2-3 times weekly can provide sufficient Omega-3 levels. A typical serving (about 100 grams) offers roughly 2-3 grams of EPA/DHA, suitable for daily intake targets.
