Creatine Monohydrates Antioxidant Properties Protect Against Oxidative Damage

Creatine Monohydrates Antioxidant Capacity

A recent research study provides further evidence to support creatine monohydrates antioxidant properties (Rahimi 2011). Previous studies have highlighted the antioxidant potential of creatine (Lawler et al., 2002; Royes et al., 2006; Sestili et al., 2011). In this study (Rahimi 2011) the researcher looked at whether creatine monohydrate could reduced oxidative stress by looking at two known markers of oxidative stress: 1) Malondialdehyde (MDA) - a highly reactive naturally occurring organic compound that is a marker for oxidative stress and indicates lipid peroxidation, and 2) 8-hydroxy-2-deoxyguanosine (8-OHdG) - a widely used biomarker for oxidative stress and carcinogenesis. It appears that creatines antioxidant properties may provide some protection against damage to DNA and lipids. 

In Summary:

In addition to the research proven benefits of creatine monohydrate on sporting performance it also appears to provide protection against the oxidative stress and oxidative damage induced by resistance exercise.
