Yet Another Amazing Benefit of Vitamin D

factoids-banner-sunshineMost of us, especially in the Northern Hemisphere, are deficient in vitamin D. In fact, the Food and Drug Administration has recently increased the recommended daily allowance from 400 IU to 800+ IU. Research has shown that vitamin D is beneficial for immune health, brain health, and more. And now a study by Italian researchers has found that vitamin D may benefit heart health. This small study looked at a group of heart failure patients, averaging 74 years old, with low vitamin D levels. Half the group took 4,000 IU vitamin D daily for 25 weeks, and the other half took a placebo. The vitamin D group experienced an improvement in ejection fraction rate (how well blood is being pumped out of the heart) by over 20%, but the placebo group worsened. The vitamin D group also lowered their systolic blood pressure.
