NOL, Nutraveris Online, the most efficient data solution to create, keep up-to-date and launch your products in the 28 EU member states, used for 10years by more than 500 industry leaders informs you:


Vitamin C is a strong antioxidant. The authors of this study wished to determine whether this antioxidant capacity can help to prevent exercise-induced muscle damage. 19 healthy women have been recruited for this randomized, double-blinded and placebo-controlled trial which used a crossover design including a 1-week washout period.

They performed 30 min moderate intensity cycling after ingesting 1 g vitamin C or placebo.

Vitamin C

Vitamin C prevented the increases in plasma albumin and total protein levels, and the reduction in glucose observed after placebo (p = 0.001). Superoxide dismutase was increased after placebo but not after vitamin C (p = 0.002), whereas malondialdehyde decreased only after the vitamin C supplementation (p < 0.05). Slight muscle damage have been noted in both groups after exercise, without differences between groups.


Therefore, vitamin C possesses antioxidant effects during exercise, but does not prevent muscle damage.
