  Alpha-Lipoic Acid
Lipoic acid shows evidence of being effective in the treatment of diabetic neuropathy and may be useful in treating some other aspects of diabetes.
Lipoic acid is believed to work in this context, at least in part, through its antioxidant properties and its reported ability to increase cellular levels of glutathione that are typically depleted by the reactive oxygen species formation that characterizes ischemia-reperfusion.
Claims that lipoic acid slows aging of the brain and is an anti-aging substance generally seem to be related to its potent antioxidant properties.
