Probiotics lower triglyceride level in Korean study

Remember triglycerides?

They’re a type of fat in your blood, and are measured to help determine your heart health. Most health practitioners believe having a high level of triglycerides will increase your risk of heart disease.

The American Heart Association (AHA) recommends that a triglyceride level of 100 mg/dL (1.1 mmol/L) or lower is considered “optimal.”Mayo Clinic lists the “normal” level as less than 150 milligrams per deciliter (mg/dL), while borderline is 150 to 199 mg/dL, and high is 200 to 499.

Now a new study from South Korea suggests help for managing high triglycerides with probiotics.


Data from a randomized, double-blind, placebo-controlled study with 92 people with borderline-to-moderate triglyceride levels indicated that the probiotic supplementation was associated with a 20% reduction in triglyceride levels.

The 12-week intervention study was also associated with a 25% increase in the levels of apolipoprotein A-V, which is known to be an important modulator of triglyceride levels.

The study utilized daily supplementation of Lactobacillus curvatus and L. plantarum. The results were published in Nutrition, Metabolism and Cardiovascular Diseases.

While the study adds to a long list of nutritional benefits provided by friendly bacteria (probiotics), the study’s authors noted, “Additional investigations are needed to identify how the various responses, mechanisms, and relevant pathways related to lipid metabolism are influenced by various probiotics.”

In the meantime, I suggest you keep taking your probiotic supplement for all the other proven benefits… while knowing it is highly likely they’re also supporting your heart health.
