Omega-3s and Vitamin D3: A Powerful Combo for Heart Health

A placebo-controlled trial using data from the VITAL trial, which investigated the effects of omega-3s and vitamin D3, found that supplementation with omega-3s plus vitamin D showed improvements in electrocardiographic measures indicative of better heart health. The study observed small but clinically significant changes in the electrocardiograms of the omega-3s group, suggesting potential effects on cardiac electrophysiology. Omega-3s expert Dr. William S. Harris praised the findings, emphasizing the need for further research to determine who will benefit the most from increasing their omega-3 intake.
