Niacin (Vitamin B3) and Neuropathic Pain: Latest Research 2026

This page summarizes the current state of scientific research on Niacin (Vitamin B3) in the context of Neuropathic Pain as of 2026. The field evolves rapidly — this is a research summary, not medical advice. Consult your neurologist or pain specialist for personalized guidance.

Compound Overview

Niacin (Vitamin B3) (B Vitamin / NAD+ Precursor) — OTC supplement; prescription doses (Niaspan) FDA-approved for dyslipidemia

Mechanism of action: NAD+ precursor via Preiss-Handler pathway; GPR109A receptor agonist (flush); HDL-raising; anti-inflammatory

Current evidence level: Strong lipid data (older studies); AIM-HIGH and HPS2-THRIVE negative for CV outcomes; NAD+ boosting confirmed

2026 Research Landscape

Direct research on Niacin (Vitamin B3) specifically for Neuropathic Pain remains limited as of 2026, though the mechanistic connections continue to be explored in laboratory settings.

Key areas researchers are currently examining include:

  • Mechanistic studies: Understanding precisely how Niacin (Vitamin B3) affects the biological pathways involved in Neuropathic Pain progression
  • Safety characterization: Defining appropriate doses and monitoring protocols if clinical use is considered
  • Biomarker identification: Finding measurable indicators that could predict which patients might respond
  • Screening studies: Preclinical models are still being used to establish whether clinical investigation is warranted

Where to Find the Most Current Research
