Effect of 4-Year Antioxidant Treatment with Alpha-Lipoic Acid
What is in NutriNerve® 2.2?
A patented formulation that supports the body against neuropathy*
The aim of this study was to evaluate the efficacy and safety of [alpha]-
lipoic acid over 4 years in diabetic patients with mild to moderate distal
symmetric polyneuropathy (DSP). In this multicenter, randomized,
double-masked, paral el-group clinical trial 460 diabetic patients with
