If you’re too heavy and know you need to work out but just can’t make it happen,
a boost of vitamin C may help you out. New research from the University of Colorado,
Boulder, found that taking a vitamin C supplement may have some similar heart-health benefits
to regular exercise in obese and overweight adults. This study focused on the endothelin
(ET-1) protein. ET-1 is responsible for constricting blood vessels, which reduces blood flow and
increases the risk of heart disease. Levels of this protein are raised in people who are
obese or overweight. These researchers studied 35 sedentary, overweight and obese adults
over three months. One group took a time-release vitamin C supplement of 500 milligrams per
day. The other group participated in a walking regimen for aerobic exercise. While these
researchers did not observe any changes in body composition, blood pressure or metabolism,
they found that ET-1 levels were similarly reduced in both groups. The study authors
concluded saying more research is needed.
