Vitamin C is well known as a dietary antioxidant, but less well known is its potential role in exercise. Researchers from the Department of Exercise Physiology at Guilan University in Rasht, Iran, evaluated the effect of vitamin C supplementation on exercise-induced lipid peroxidation, muscle damage and inflammation. Sixteen healthy untrained male volunteers, randomly assigned to either a placebo or vitamin C group (1,000 mg), participated in a 30-minute exercise at 75% of VO2max. Blood samples were taken before supplementation and after supplementation, before exercise, immediately after exercise, and 2 and 24 hours after exercise. After measuring and comparing blood levels of various markers for muscle damage, stress and inflammation, researchers concluded that vitamin C supplementation prevented endurance exercise-induced lipid peroxidation and muscle damage. This latest study confirms a growing body of work that supports the use of vitamin C as a supplement to improve recovery from exercise.
