A growing library of the omega-3 research we're following — summarized and categorized so you can find what matters to you.
Breast milk DHA levels in Balkan mothers fell below the optimal threshold, even among those taking standard supplements.
Mature breast milk had higher omega-3 and omega-6 fatty acid levels and lower leptin/adiponectin than colostrum, with these fats inversely linked to the two hormones.
Combining vitamin D and DHA for 12 months improved cognitive test scores and lowered inflammation-related blood markers more than either nutrient alone in older adults with mild cognitive impairment.
A review of existing studies found that omega-3 and related fatty acids were linked to improved blood pressure, cholesterol, and kidney injury markers in diabetic kidney disease, though evidence remains mixed and more research is needed.
Fatal COVID-19 was associated with widespread depletion of EPA and DPA across body tissues, while DHA was often relatively preserved, especially in the brain.
Adding omega-3 supplements to standard gum disease treatment was linked to modest improvements in gum health measures across 15 trials, though evidence quality was low.
Vitamin D3 and omega-3 supplements didn't significantly change key Alzheimer's-related blood biomarkers overall, though some subgroup differences by sex and race warrant further study.
Lower blood levels of DHA appear to help explain why ultra-processed food intake is linked to higher Crohn's disease risk.
In a meta-analysis of preterm infants, IV fat emulsions containing fish oil showed a consistent trend toward lower liver disease risk compared to soybean oil alone, but evidence certainty was low.
