Older adults who take a novel antioxidant that specifically targets cellular powerhouses, or mitochondria, see age-related vascular changes reverse by the equivalent of 15 to 20 years within six weeks, according to new University of Colorado Boulder research. The study, published this week in the American Heart Association journal Hypertension, adds to a growing body of evidence suggesting pharmaceutical-grade nutritional supplements, or nutraceuticals, could play an important role in preventing heart disease-the nation's No. 1 killer. 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, the authors say. "This is the first clinical trial to assess the impact of a mitochondrial-specific antioxidant on vascular function in humans," said lead author Matthew Rossman, a postdoctoral researcher in the department of integrative physiology. "It suggests that therapies like this may hold real promise for reducing the risk of age-related cardiovascular disease." Read more:
