Antioxidant supplementation (Vitamin C, Co-enzyme Q10) does not improve recovery from exercise-induced muscle damage and may potentially delay recovery or worsen performance in some contexts.

Do not rely on antioxidant supplements like Vitamin C or CoQ10 to speed up your recovery after exercise. They do not improve recovery rates and may even slow it down or increase muscle damage in some cases.

The group receiving supplementation was no different from a placebo group in the rate of recovery... The players using supplementation were inferior to the control group on selected exercise performance tests, showed greater muscle damage and slower rates of recovery after the period of elevation in training load.
