Vitamin D can improve Heart Failure

Today is the last day of National Heart Month 2022. So, how’s your heart? Did you know that cardiovascular disease (CVD) is the #1 cause of death across the globe? Heart failure, a type of CVD, is the #1 reason adults over 65 get hospitalized.

Heart failure occurs when your heart can’t pump enough blood to your body. Sounds scary but there is a ray of hope that can improve the function of your heart. Enter the “sunshine vitamin,” Vitamin D!

A recent systematic review of the literature showed that Vitamin D can significantly enhance your heart’s pumping capability by increasing ejection fraction (EF) (Naghedi et al., 2020). Results from the EVITA trial (Effect of vitamin D on mortality in heart failure) showed that 4000IU of Vitamin D3 taken daily improved left ventricular EF in heart failure patients who were 50 years of age and older at 1 year- and 3 year-follow ups (Zittermann et al., 2019).

If you’re considering adding Vitamin D supplements to your routine, it’s important to get your 25(OH)D blood levels checked three months after you start.
