VASCULAR FUNCTION & OMEGA-3 FATTY ACIDS IN SMOKERS

Smoking negatively affects the cells lining the blood vessels (endothelial cells) and reduces the body’s output of plasminogen activator (t-PA), a substance involved in the normal breakdown of clots within the vessels. Previous research has linked fish oil to heart health benefits associated with improvements in blood lipid levels, blood pressure, heart rate, reductions in clotting, and overall vascular health.

In a study published in the journal Heart, researchers investigated the effects of omega-3 fatty acid supplementation on cardiovascular health and vascular function in otherwise healthy smokers. The randomized, double-blind, placebo controlled crossover trial included 20 cigarette smokers that were given either 2 grams of fish oil or placebo for a 6 week period.

The daily fish oil supplements were associated with an increase in t-PA at twice the level of the placebo group. Substances known to dilate blood vessels, thereby increasing blood flow, were also significantly higher in the omega-3 supplemented group compared to placebo.

This study is the first to show that omega-3 fatty acids may enhance endothelial t-PA release and improve endothelial vasomotor function in cigarette smokers. The researchers note that while the omega-3 supplements may have improved vascular function in smokers, they still aren’t likely to match the endothelial function of non-smokers, so quitting smoking is still a key factor in reducing heart disease risk.

At Smile Acapulco we both use and recommend USANA's BiOmega to all our patients. Nowadays, with GMO's, processed foods and a host of junk food it's harder (and more expensive) than ever to eat healthy. Should you like to know about USANA's products and how they can help you please contact us at [email protected]. We'll be more than happy to make a custom-made recommendation for you.

Thanks for reading!
