Are you among those people who don’t like to get up early and go for a walk, but worry about being obese? A new study will provide a big relief to you. The study concluded that Vitamin C supplements can be as effective as exercise.

The study, which included about 35 obese or overweight adults, examined effects of vitamin C and then exercise’s effects on endothelin-1, a protein which has constricting action on small blood vessels.

The study found raised activity of the protein in obese people and the activity leads small vessels to become more prone to constricting. The findings of the study are presented at the American Physiological Society's 14th International Conference on Endothelin, taking place in Savannah.

According to the researchers, regular exercise can be helpful in reducing the endothelin-1 activity, but it is not easy to include it in a daily routine. Caitlin Dow, a researcher from the University of Colorado, and some other researchers conducted the study to find out if vitamin C supplements could also reduce the endothelin-1 activity.

The study showed that daily dose of vitamin C can provide help in reducing endothelin-1-mediated vessel constriction like daily exercise did. Out of 35 participants, 20 were asked to take supplement, while 15 were enrolled for aerobic exercise.

The study concluded that daily supplementation of Vitamin C can reduce ET-1-related vessel constriction effectively. A 2013 study found that vitamin C benefits individuals under heavy physical stress.
