Omega-3s: Do They Help You Sleep?

Omega‑3 fatty acids—EPA, DHA, and ALA—are essential nutrients linked to brain, heart, and inflammation regulation. While DHA may boost melatonin and neuronal stability, research on sleep benefits remains mixed, with modest gains in some trials but no clear advantage for most adults. About 90‑95% of people fall below the optimal Omega‑3 Index, prompting many to consider fish‑rich diets or supplements. The strongest sleep‑related evidence appears in children, pregnant women, and those with sleep‑disordered breathing.
