General: 14-16 mg/day NE (RDA); Cognitive Support: 500-1,500 mg/day niacinamide

What are the side effects of Niacin?

Potential side effects include: Flushing (nicotinic acid form), Gastrointestinal discomfort, Liver toxicity at sustained high doses, Elevated blood sugar.

Niacin (vitamin B3) is an essential nutrient that participates in over 400 enzymatic reactions in the body. It is a precursor to NAD+, a coenzyme critical for cellular energy metabolism and DNA repair. Research has explored niacin's potential role in supporting brain energy metabolism and neuroprotection.

What dosage of Niacin has been used in cognitive studies?

Dietary studies have associated higher niacin intake (around 20 to 45 mg per day) with better cognitive outcomes in older adults. Therapeutic doses used in clinical settings range widely. Niacinamide and nicotinamide riboside are alternative forms that avoid the flushing effect. Consult your doctor.

About

Niacin is essential for NAD+ and NADP+ coenzymes critical for mitochondrial energy production, DNA repair, and sirtuin activation in neurons. NAD+ depletion is implicated in neurodegeneration and is a major research frontier.

How It Works

Essential precursor to NAD+ and NADP+ coenzymes critical for mitochondrial energy production, DNA repair, and sirtuin activation in neurons; supports cerebral blood flow through vasodilatory effects.

Elevated blood sugar

Drug & Supplement Interactions

Statins (increased myopathy risk with nicotinic acid)
