Niacin (Vitamin B3) and Parkinson's Disease: A Patient-Friendly Research Overview

If you or a loved one has Parkinson's Disease and you've heard about Niacin (Vitamin B3), this guide explains what the research actually shows in plain language. We believe patients deserve honest, clear information — not hype, not dismissal. This is a research summary only. Always work with your neurologist or movement disorder specialist.

What is Niacin (Vitamin B3)?

Niacin (Vitamin B3) is classified as a B Vitamin / NAD+ Precursor. In simple terms, it works by: NAD+ precursor via Preiss-Handler pathway; GPR109A receptor agonist (flush); HDL-raising; anti-inflammatory...

Its current regulatory status: OTC supplement; prescription doses (Niaspan) FDA-approved for dyslipidemia

Why Are Parkinson's Patients Asking About Niacin (Vitamin B3)?

Researchers and patients with Parkinson's have explored Niacin (Vitamin B3) because of its specific mechanisms that may be relevant to Parkinson's biology. This has generated both scientific publications and patient community interest.

What the Research Actually Shows

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

This means: There is scientific research specifically examining this combination, providing more than just theoretical interest.

Safety in Plain Language

What you should know about Niacin (Vitamin B3) safety: Flushing common (reduced with extended release); hepatotoxicity at high doses; glucose effects; gout risk

Important: even compounds with favorable safety profiles can have risks in Parkinson's patients due to interactions with treatment or disease-related organ changes.
