Alpha lipoic acid (1,2-dithiolane-3-pentanoic acid) acts in the body as a cofactor in the production of energy. Human studies have found that alpha lipoic acid improves insulin sensitivity (183, 184, 186) ., as well as vasodilation (decreases blood pressure) and polyneuropathy (nerve damage) in patients with diabetes mellitus (diabetes with high levels of blood glucose) (183, 184) . In another 12 week study, it was found that Alpha lipoic acid cream may help prevent photo aging of facial skin (185) and may be helpful with the following: it may help protect cataract formation (187) , may help with bone loss (188, 189) , may reduce intensity and frequency of migraines (190) , helps improve visual function in those with glaucoma (191) , helps protect against cataract formation (192) , helps improve skin texture (185) , and increases insulin sensitivity (183, 184, 186)
