Synopsis

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

Flavanols are a class of polyphenolic compounds found in foods such as cocoa, green tea, and certain fruits. There is emerging scientific interest in the potential of flavanols to support vascular health and improve blood flow, which is relevant to peripheral neuropathy—a condition often associated with reduced nerve blood supply and oxidative stress. Some small-scale clinical trials and preclinical animal studies have investigated the effects of cocoa flavanols on nerve function and symptoms of neuropathy, particularly in diabetic populations. For example, a few studies have shown that flavanol-rich chocolate or supplements can improve microcirculation and endothelial function, which may indirectly benefit nerve health. However, direct evidence showing that flavanols significantly improve peripheral neuropathy symptoms or alter its course is limited and generally of low quality, with small sample sizes and short durations. There is not yet consistent, high-quality evidence (such as multiple large randomized controlled trials) supporting the routine use of flavanols for peripheral neuropathy. Current scientific support is therefore preliminary, and flavanols should not be considered a primary treatment for this condition. Instead, they may be explored as an adjunct to conventional therapies pending further research.
