Statement on Omega-3s, Vitamin D3, and Recent Studies from John Troup, Ph.D., CHPA Vice President of Scientific Affairs and Dietary Supplements

“An estimated 40 percent of Americans are deficient in nutrients with only 20 percent of Americans meeting daily nutrient requirements. A growing body of scientific evidence shows that dietary supplements are beneficial for individuals who need higher levels of certain nutrients including omega-3 fatty acids and vitamin D3 for people at-risk for various cardiovascular diseases (CVDs). Ongoing large-scale clinical studies are helping to better understand the role that nutrient supplementation can play in personal healthcare.

“While the VITAL Rhythm study reported ‘no benefit’ from omega-3s and vitamin D3 for prevention of atrial fibrillation (AF) — one of several types of CVD — other studies support the health benefits of omega-3s and vitamin D3, for example to support the immune system response and underlying metabolic systems. Overall, the weight of evidence continues to point to health benefits. This includes a 2017 meta-analysis of 40 studies involving omega-3s and over 135,000 patients that concluded omega-3s are “an effective lifestyle strategy for CVD prevention, and [that] the protective effect probably increases with dosage.” In addition, the American Heart Association recommends patients with heart disease consume 1 gram of omega-3 fatty acids daily from supplements if unable to do so from diet alone.

“When used appropriately, dietary supplements like omega-3s and vitamin D3 play important roles in personal healthcare by filling nutritional gaps, supporting certain condition-specific needs, promoting healthy body functions, and contributing to overall wellness. Consumers should always carefully read Supplements Facts labels for ingredients and instructions for use. Labels must bear appropriate ingredient and nutrition information and should not bear claims to treat or cure diseases. Consumers should always look to reputable companies and be wary of supplements that make claims that are ‘too good to be true’.  Learn more from the CHPA Educational Foundation.“
