Vitamin C reduces risk of heart failure

In one study, doctors measured vitamin C levels in the diets of 212 men and women, average age 61. About half of the group had moderate to severe heart failure—when the heart does not pump enough blood to the body.

Doctors wanted to test for a link between vitamin C levels and signs of inflammation. Compared to those who got the most vitamin C, those with heart failure who got the least vitamin C were 2.4 times more likely to have high levels of high-sensitivity C-reactive protein (hs-CRP), a sign of inflammation and a factor in heart disease.

Doctors found that as the level of vitamin C increased, the level of hs-CRP decreased, and after a year of follow-up, those with the highest levels of vitamin C lived longer without a cardiac event.
