Study answer

What this study found

Significant reductions in UPDRS III scores were observed in both groups after twelve months, with trends towards improvement in rigidity and bradykinesia noted. Niacin supplementation was associated with better serum serotonin levels, reduced fatigue, and improved grip strength.

Study & population
47 mild to moderately severe Parkinson's patients were enrolled, stabilized on medications for three months, and randomized to receive either niacin or placebo.
Intervention
Randomized, double-blind, placebo-controlled trial investigating low-dose niacin (250 mg daily) for motor function improvement in veterans with Parkinson's disease.
Key limitation
Small sample size, lack of titration for niacin dosage, gender bias in the population (predominantly men), and reliance on self-reported outcomes for some measures.
