Vitamin C, known for its vital benefits in curbing scurvy and anemic conditions is known to have also similar cardiovascular benefits that one gets by daily exercise. However, it may not replace exercise but certainly supplements for obese and old people, say scientists.
Available in citrous fruits such as lemons, oranges, amla among others, vitamin C can mimic the the benefits of exercise, said the study. Since the blood vessels of obese adults have an elevated activity of a protein called endothelian (ET)-1, which constricts the small vessel and increases the risk of developing cardiovascular diseases as vessels become thicker to allow blood flow, the situation can be reversed with higher ET-1 levels, says the new study.
The study, conducted at the University of Colorado, Boulder, examined whether vitamin C supplements, which have been reported to improve vessel function, can also lower ET-1 activity.
The researchers found that daily supplementation of vitamin C (500 mg/day, time-released) reduced ET-1-related vessel constriction and the method represents an effective lifestyle strategy for reducing ET-1-mediated vessel constriction in overweight and obese adults, the researchers argued.
The daily supplements of Vitamin C of up to 500mg/day reduced ET-1-mediated vessel constriction in overweight adults that they would have achieved after a daily walk, said researchers whose findings have been presented at the 14th “International Conference on Endothelin: Physiology, Pathophysiology and Therapeutics” in Savannah, Georgia.
The flipside of it is that Vitamin C has been found to have added more kidney stones in the body. Some other studies have brushed aside the intake of Vitamin C as it is not able to reduce free radical damage as previously thought.
