Vitamin E Exerts Positive Effects on Various Health Markers in Recreational Trainees

A study from scientists from the Azad University in Iran (Naghizade. 2010) shows that supplementation with 500mg vitamin E (~750IU) over a period of 8 weeks improved malondialdehyde (MAD, p<0.02) , creatine phosphate (CP, p<0.04), total antioxidant capacity (TAC, p<0.03), LDL (p<0.03) and Vo2max (p<0.03) over placebo values in moderately aerobically trained individuals:
In summery performing moderate aerobic exercise (HRmax 60-65%) with consumption Vitamin E may decrease membrane damage and lipid peroxidation, and cardiovascular risk factors.
These results stand in line with several other papers that have been released within the last months. Many of these found positive effects of vitamin E on moderately (mostly aerobically) training trainees, like the ones in this studies. If, however, the workloads increase way beyond the 3x45min (per week) the male subjects of this study spent in the gym, the results become equivocal and some studies even suggest that additional anti-oxidant supplementation may suppress positive adaption processes.
