Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Vitamin B6 (pyridoxal, or more commonly, pyridoxine) has traditionally been used to support or treat symptoms such as burning feet or hands, particularly in the context of peripheral neuropathy. Historical records from the early to mid-20th century report that nutritional deficiencies, including vitamin B6 deficiency, were associated with neuropathic symptoms, especially in populations with poor diets or malabsorption syndromes. The "burning feet syndrome" was once described in prisoners of war and malnourished individuals, where B vitamin deficiencies were implicated.

However, rigorous scientific validation for the use of vitamin B6 supplementation to treat burning feet or hands outside of clear deficiency states is limited. While B6 is essential for nerve function and its deficiency can cause sensory neuropathy (with symptoms such as burning, tingling, and numbness), most cases of burning feet or hands in the modern era are not due to B6 deficiency. Moreover, excessive B6 supplementation itself can paradoxically cause sensory neuropathy and similar symptoms.

In summary, the use of vitamin B6 for burning feet or hands is primarily rooted in traditional medical practice and anecdotal reports, with moderate evidence supporting its use only in cases where deficiency is present. There is insufficient high-quality, contemporary research supporting its efficacy in idiopathic neuropathic symptoms or in individuals without deficiency.
