In people with diabetic nerve damage, this supplement combo reduced pain scores from 20.9 to 13.9 over 6 months—a significant drop. It also improved nerve function markers like nerve conduction speed and vibration sensation, while the placebo group saw no pain improvement and actually got worse on one measure.

73 people with type 2 diabetes and nerve damage took either the supplement (2 tablets daily) or placebo for 6 months. Researchers measured pain, nerve function, and quality of life using standardized clinical tests.
