Big effect
A systematic review of 1,367 people found folate supplementation linked to a 3-point pain reduction for peripheral neuropathy — but the exact dose was not specified across the pooled studies.
This is the first systematic review on folate for nerve pain, so while the effect is large and statistically significant, the missing dose detail and early-stage evidence mean it's promising but not yet definitive.
Researchers pooled data from multiple studies totaling 1,367 participants and found that taking vitamin B9 (folate) eased nerve pain by an average of 3 points on a pain scale. The review also noted improvements in nerve structure and blood markers, but because the dose wasn't standardized or reported in every study, you can't yet copy the exact regimen. It's an exciting first look, but expect more precise trials to come.
Where this fits in the evidence
This is among the first studies we've indexed on Vitamin B9 for Reduced Pain — treat it as an early signal until more research accumulates.
