Omega-3s Go Beyond Heart Health

We’ve seen a lot of research on the benefits of omega-3s for cardiovascular benefits, but new research is showing so much more. One recent meta-analysis of forty randomized controlled trials found that high doses of EPA/DHA outperformed existing pharmacological interventions in prophylactically treating migraines, with the greatest decreases in migraine frequency and severity. Another study found that taking omega-3 fatty acids was associated with a significant increase in serum levels of brain-derived neurotrophic factor (BNDF), compared to a placebo group. BDNF is a protein in the brain and nerves that preserves nerve cells and encourages the growth of new ones, a process called brain plasticity, which supports brain function as we age. BDNF also plays an important role in learning, memory, and behavior. Last but not least, another recent study found that omega-3 supplementation (as well as separate vitamin D supplementation) reduced the risk of autoimmune disease. In this study, participants took the omega-3s for five years, but the risk reduction was prevalent even two years after supplementation was discontinued.
