The Dynamic Duo of Omega-3s and Vitamin D for Healthy Hearts

View All Section Pages

More than 200 years ago Scottish philosopher David Hume wrote, "A wise man proportions his belief to the evidence." Today, that advice still holds true, especially when it comes to nutritional supplementation.

In the multi-billion dollar vitamin and supplement industry, products often claim more "sizzle" than "steak." However, when you look at the research, evidence shows that supplementation with appropriate nutrients makes sense for most people. The key being "appropriate nutrients," and when it comes to heart health there are two nutrients in particular we should pay close attention to - omega-3 and vitamin D.

Connecting Healthy Hearts to Omega-3s
The cardiovascular benefit of omega-3 fats is not a new health discovery. It was identified in the early 1970s by Jorn Dyerberg, MD, DMSc, and his colleagues in Greenland. They sought to understand how Eskimos living in Greenland could eat a high-fat diet - consisting mostly of fish and seal - and still have one of the lowest death rates from cardiovascular disease in the world. Through research they found the answer: omega-3 fats. Their work was published in The Lancet and The American Journal of Clinical Nutrition.

Today more than 18,000 published studies show the benefits of omega-3 fats, especially for the heart because they help lower blood pressure, resting heart rate, risk of arrhythmia, sudden death and triglycerides. Omega-3 fats also improve the HDL/LDL cholesterol ratio and reduce the risk of developing metabolic syndrome.

Noted omega-3 researcher William Harris, PhD, touts the cardiovascular benefits stating, "There is no nutrient more important for decreasing risk of cardiovascular death - and more lacking - than omega-3."

It's in the Label
When it comes to buying nutritional supplements it pays to be an educated consumer. This is particularly the case with omega-3 fats, which are often referred to, almost interchangeably, as fish oil and or poly-unsaturated fatty acids. Not all omega-3 products are created equal?the important ingredients to look for are the amounts of EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) in the product.

EPA and DHA are the "long chain" omega-3s that are so beneficial for the heart as well as the brain, eyes and immune system. EPA and DHA come from the micro-algae that fish eat, especially fatty fish such as salmon, trout, mackerel, anchovies and sardines.

For maximum benefit most experts recommend at least 1,000-2,000 mg of EPA and DHA combined every day. If you are eating fatty fish at least three to four times a week, you are probably getting enough omega-3 fats from your diet. However, studies indicate that Americans eat fish once every 11 days on average.

When determining which omega-3 supplement product is the best buy, you will need to do some detective work. That is, read the small print on the back of the bottle. Well over half of omega-3 products provide only a 30 percent concentration of EPA and DHA. That means every 1,000 mg (1 gram) soft gel will give you 300 mg of EPA and DHA. With that in mind you will need to take four soft gels per day to total 1,200 mg of EPA and DHA.

The higher quality - and often best value - fish oils provide a 50-60 percent concentration, which means you need to take just two 1,000 mg soft gels per day to reach the target daily dose.

The Vitamin D Dilemma
The other nutrient that deservedly is currently getting lots of positive press is vitamin D, which actually is not a vitamin at all. It's a steroid hormone manufactured, or synthesized, by our body when UVB light from the sun hits our skin. We can also get some vitamin D from our diet by consuming fish, milk and fortified cereal. But it's difficult to get the proper dosage through food alone.

Vitamin D was "discovered" when many children in New England began developing rickets during the winter months. Rickets is a softening of the bones in children that can potentially lead to fractures and deformity (osteomalacia is a similar condition in adults). There was limited sunshine during the day and everyone wore long pants, coats and hats due to the cold temperatures, making it difficult for the children's bodies to synthesize enough vitamin D. Because vitamin D regulates the uptake of calcium into the bones, without enough of it the bones simply won't calcify.
