Selenium and CoQ10 May Help Support Cardiovascular Health Long-Term
Selenium and CoQ10 both act as antioxidants, meaning they help protect cells from free radicals and help reduce oxidative stress. According to a recent study, supplementation with selenium and CoQ10 may help reduce inflammation and oxidative stress and improve cardiovascular health.
Participants in the study included 443 adults with an average age of 79. All had a low selenium status and a low level of CoQ!10 at the beginning of the study period. They were given 200 mcg of selenium and 200 mg of CoQ10 daily for 48 months.
The researchers evaluated biomarkers related to inflammation and oxidative stress at baseline and at the end of the study period. They also evaluated biomarkers associated with fibrosis and endothelial dysfunction.
Participants in the supplement group saw a significant decrease in inflammation and oxidative stress biomarkers at the end of the 4-year study period compared to the placebo group. They also saw a reduction in biomarkers of fibrosis and improvements in cardiac function.
Those taking the supplements also experienced a significant reduction in death from cardiovascular disease compared to the placebo group, after both 5 years and 10 years.
The study was conducted by researchers from Linköping University. It was published online ahead of print on April 6, 2022 in the European Journal of Nutrition.
A previous study found that higher intake of selenium may help reduce the risk of death from heart disease.
