What are the antioxidant properties of Glutathione

Attempts to improve linear growth by rhIGF-I treatment has been reported to result in some improvements in a few affected children but not all (134, 135) It is beyond the scope of this chapter to review the overwhelming evidence from cell biology experiments demonstrating the important role of IGFBPs in modulating IGF bioactivity and the role of IGFBP proteases and their actions at the cellular level

This helps in the synthesis of antioxidants, especially glutathione

The safety profile is generally favorable, with most side effects being GI-related (nausea, constipation, diarrhea) that improve with time and gradual dose escalation
