Patients - methods: In this pilot study, 61 patients with Diabetes Mellitus Type 2 (DMT2, 31 women), with mean duration of DM 17.5 years and mean age 63 years were randomly assigned, either to receive the combination of ten elements (2 tablets/24h) in the active group, (n=30), or the placebo (n=31) for 6 months. We used Michigan Neuropathy Screening Instrument Questionnaire and Examination (MNSIQ and MNSIE), measured vibration perception threshold (VPT) and Cardiovascular Autonomic Reflex Tests (CARTs). Nerve function was assessed by DPN Check [sural nerve conduction velocity (SNCV) and amplitude (SNAP)]. Sudomotor function was assessed with SUDOSCAN that measures electrochemical skin conductance in hands and feet (ESCH and ESCF). Pain (PS) questionnaire was administered, also. All patients received metformin for at least 4 years.

Inclusion Criteria:
