Diabetic neuropathy (DN) is one of the major complications of diabetes and the most common cause of neuropathic pain. Although the underlying pathological mechanisms remain unclear, several studies have produced conflicting results regarding the link between magnesium (Mg) concentration and DN. This ambiguity raises questions about the potential benefits of Mg supplementation in individuals with DN. Therefore, this comprehensive review summarizes and discusses the evidence from clinical, in vitro, and in vivo studies on the association between Mg and DN. Several findings indicate that Mg depletion is linked to the presence of neuropathy in diabetic patients. Additionally, low Mg concentration may contribute to the onset or worsening of DN by promoting axonal degeneration through various pathways. Furthermore, multiple studies have shown that Mg supplementation can have neuroprotective effects. These findings suggest potential as an alternative or complementary therapy for preventing and treating DN in the future.
