Are probiotics effective at improving heart health?

Marlene Walling

Probiotics have become increasingly popular in recent years as people have become more aware of the importance of gut health for overall health. While the focus has been primarily on the digestive system, some studies suggest that probiotics could also benefit heart health.

First, let's define what probiotics are. Probiotics are live microorganisms that, when introduced into the body, can confer health benefits. They are often found in fermented foods such as yogurt, kefir, and sauerkraut, and can also be taken in supplement form.

One study published in the European Journal of Clinical Nutrition found that taking a probiotic supplement for 12 weeks resulted in a significant reduction in total cholesterol levels. High cholesterol is a risk factor for heart disease, so this is an encouraging finding. Another study published in the Journal of the American College of Cardiology found that a specific strain of probiotics called Lactobacillus reuteri reduced arterial stiffness, another risk factor for heart disease.

However, it's important to note that not all probiotics are created equal, and more research is needed to determine which strains and dosages are most effective for heart health. Additionally, while these studies show promising results, they are relatively small and short-term, so it's uncertain whether the benefits would hold up over the long-term.

It's also worth noting that taking probiotics alone is unlikely to have a significant impact on heart health. A healthy diet, regular exercise, not smoking, and managing stress are all important factors in reducing your risk of heart disease.

In conclusion, while early studies suggest that probiotics may have a positive effect on heart health, more research is needed to determine their full potential. In the meantime, focusing on overall lifestyle factors such as diet and exercise is the best way to reduce your risk of heart disease.
