Researchers have found that Vitamin C is just good as exercise for the obese or overweight. The findings are important especially for those who cannot incorporate exercise into their daily routine.

The obese and overweight can reduce their risk of cardiovascular disease if they take vitamin C supplements daily. New research from the University of Colorado suggests that vitamin C can be as effective as exercise for obese, overweight adults.

The obese and overweight people are advised to exercise for improving their health but only less than 50% took up an exercise regimen.

Now researchers have found a sort of solution to this problem. They indicate that regular intake of Vitamin C may offer similar benefits to the obese or overweight as exercise. For the research, 15 subjects were asked to do brisk walking while 20 were asked to take vitamin C supplements daily. The trial period continued for three months. Neither group lost any weight at the end of the trial but, their blood vessel function improved and the risk of developing heart disease was also reduced.

The blood vessels of obese or overweight have high activity of the protein endothelin (ET)-1. Because of elevated levels of endothelin-1, blood vessels become more susceptible to constricting, meaning they are less responsive to blood flow demands. It is already proven that exercise lowers ET-1 activity but scientists here want to know whether vitamin C can also contribute in reducing ET-1 activity.

They have found that taking high dose of vitamin C supplement, 500 milligrams every day, can reduce ET-1 related constriction as much as walking did.

The study’s lead author, Caitlin Dow, suggests that the study is especially important for those people who find it difficult to incorporate exercise into their daily routine. But it cannot certainly be a replacement for exercise as it cannot offer broader benefits as exercise can.

“This is not “the exercise pill,” Dow said. “If we can improve different measures of risk for disease without changing weight, it takes a little bit of the pressure off some people. It’s important to know what other lifestyle changes we can offer people who can’t exercise.”

The study was published in American Psysiological Society
