Antioxidants Makes Old Blood Vessels Seem Young

Antioxidants makes old blood vessels seem young, according to a study conducted on April 19, 2018.

This study was conducted by researchers at the University of Colorado Boulder. This study suggests that pharmaceutical-grade nutritional supplements or nutraceuticals could help in the prevention of heart diseases. It also resurrects the notion that oral antioxidants, which have been broadly dismissed as ineffective in recent years, could reap measurable health benefits if properly targeted.

Matthew Rossman, lead author said, “This is the first clinical trial to assess the impact of a mitochondrial-specific antioxidant on vascular function in humans. It suggests that therapies like this may hold real promise for reducing the risk of age-related cardiovascular disease.” 20 healthy men and women between the age of 60 and 79 from the Boulder area were included in the study by the researchers. Half of the people consumed 20 milligrams per day of a supplement called MitoQ, made by chemically altering the naturally-occurring antioxidant Coenzyme Q10 to make it cling to mitochondria inside cells and other half of the people took a placebo.

After six weeks, researchers assessed how well the lining of blood vessels, or the endothelium, functioned, by measuring how much subjects’ arteries dilated with increased blood flow. Then, after a two-week ‘wash out’ period of taking nothing, the two groups switched, with the placebo group taking the supplement, and vice versa. The tests were repeated.

It was found that when the supplement was consumed, dilation of subjects’ arteries improved by 42 percent, making their blood vessels look like those of someone 15 to 20 years younger. The improvement in dilation was due to a reduction in oxidative stress.
