Vitamin C May Improve Blood Vessel Functioning

A recent study suggests that a daily supplement of at least 500 mg of vitamin C may improve the health of the endothelium in people with diabetes, atherosclerosis, and heart failure. The endothelium is the layer of cells that lines blood vessels.

Participants in the study included 1,129 people who took part in 44 clinical trials. After analysing the data, the researchers found that taking vitamin C supplements was beneficial to endothelial function, particularly in people who were already in poor health.

Upon further analysis, however, they discovered that there was no clear correlation between endothelial function in healthy volunteers and vitamin C intake.

Researchers from Newcastle University in England conducted the study. It was published online ahead of print on April 16, 2014, in the journal Atherosclerosis.

Vitamin C is an essential nutrient that has been linked to numerous other health benefits including heart health, brain health, eye health and improved mood. It can be found in high levels in citrus fruits and dark leafy greens such as cantaloupe, oranges, kiwis, and papaya, and in dark leafy greens such as broccoli and kale.
