Does Vitamin C Provide Similar Benefits as Exercise for the Obese, Overweight Adult.


A new study published in Science Daily News  to be presented at the International Conference on Endothelin: Physiology, Pathophysiology, and Therapeutics concluded exercise will benefit overweight and obese adults but over 50%  do not included it in their daily activities.  They found that taking vitamin C supplements can have similar cardiovascular benefits as regular exercise for this population.

Blood vessels of obese and overweight adults have elevated activity of the small vessel-constricting protein endothelin (ET)-1. The high level ET-1 in the vessels makes them more prone to constricting, becoming less responsive to blood flow demand and increasing risk of developing vascular disease. Exercise has been shown to reduce ET-1 activity but is not always complied with by the obese and overweight. The study evaluated whether or not Vitamin C supplements would lower ET-1 activity. They found that daily supplements of 500 mg of time released vitamin C daily reduced ET-1 related vessel constriction as much as walking did. They concluded that vitamin C supplementation is an effective lifestyle strategy for reducing ET-1 mediated vessel constriction in overweight and obese adults.
