In overweight couch potatoes, vitamin C supplements mimic some exercise effects – Los Angeles Times

Overweight and obese people who take a high-dose of supplementary Vitamin C daily may get some of the cardiovascular benefits of exercise without the exercise, new research has found.

In a small trial that recruited sedentary adults who were overweight or obese, study participants who took 500 milligrams of Vitamin C daily saw equal improvement in blood vessel tone — a key measure of cardiovascular health — as did those who took up a three-month regimen of brisk walking five to seven times a week, investigators at the University of Colorado at Boulder reported.

The results were presented in Atlanta this week at the American Physiological Society’s annual meeting. But they have not yet been published in a peer-reviewed journal and so are considered preliminary.
