Endothelin-1, or ET-1, is a protein that can constrict small blood vessels. For people that are overweight or obese, this activity is more pronounced, leading to more constriction of blood vessels and limiting the body’s ability to properly handle blood flow. This in turn increases the risk of cardiovascular disease.
To test the effects of vitamin C for vascular health, Caitlin Dow, PhD, from the University of Colorado, conducted a study of 35 subjects. All of the subjects chosen for the study were obese, overweight, or living a sedentary lifestyle and had poor vascular tone. The subjects were examined for 3 months.
During the 3 months of examinations, 20 subjects took supplements, including 500 milligrams of vitamin C, but made no other changes to their lifestyle. The other 15 subjects were directed to a take a brisk walk, 5 to 7 times per week.
Neither group reported any significant weight loss. Even though neither group lost weight, the group that took supplements had a reduction in blood vessel constriction related to the ET-1 protein. Both groups had their vascular tone return to normal, showing that taking vitamin C is just as effective as the exercise.
Having a poor vascular tone can lead to an increase in a number of health issues, such as inflammation and an increased risk of stroke. If you are unable to engage in physical exercise, the study shows that you could at least begin taking vitamin C for some health benefits.
While the study shows that taking vitamin C for vascular health has its merits, the researchers are quick to point out that it is not your weight loss answer. It can help improve vascular tone, but if you are healthy enough for exercise, then you should make sure that you get off the couch and start including some exercise in your daily routine.
Additional Benefits of Taking Vitamin C
Along with helping to improve vascular tone, taking vitamin C can help to lower your bad cholesterol and improve your metabolism and cognitive function. It can also help boost your immune system and prevent the common cold or flu. People that suffer from hypertension can also get some relief by taking more vitamin C.
Deciding on a Vitamin C Dosage
How much vitamin C should you take? The daily recommended amount of vitamin C is around 180 milligrams per day. The dosage of 500 milligrams used in the study described is considered high, but the body should be able to handle up to 2,000 milligrams a day before your body develops gastrointestinal disturbances.
If you are looking for a way to begin improving your overall health, consider taking vitamin C for vascular health. When you are already obese or overweight, you face an increased risk of a number of diseases, including cardiovascular disease. To get yourself pointed in the right direction, get more exercise and take a vitamin C supplement.
