Peripheral neuropathy remains one of the most challenging conditions to address effectively, particularly in patients with diabetes.

While red and near-infrared light therapy has become an increasingly important tool for supporting circulation, cellular function, and nerve health, one factor may influence therapeutic response: nitric oxide availability at the tissue level.

Emerging research into the relationship between nitric oxide, vascular function, and photobiomodulation is opening new possibilities for more comprehensive approaches to neuropathy care.
