Key differences

Option A

Nicotinamide Riboside

Nicotinamide riboside (NR) is a form of vitamin B3 and the most efficient oral precursor to NAD+ (nicotinamide adenine dinucleotide). NAD+ declines 50% between ages 40-60, driving aging and metabolic dysfunction. NR uniquely enters cells via NRK1/2 pathway, bypassing rate-limiting enzymes. Patented as Niagen.

Niacin

Niacin (vitamin B3) exists as nicotinic acid, niacinamide, and nicotinamide riboside (NR). Nicotinic acid uniquely causes vasodilatory "flush" and is the most effective natural agent for raising HDL cholesterol. All forms serve as precursors to NAD+/NADH, essential cofactors for 400+ enzymatic reactions.
