Short answer: Niacin (Vitamin B3, 7.5mg NE) supports NAD+ production, the molecule that powers energy processes inside neurons, and is linked to cerebral microcirculation.
Why Niacin's role is distinct from the formula's nitric oxide ingredients
Rather than another nitric oxide precursor, Niacin contributes a genuinely different mechanism — cellular energy production specifically inside neurons via NAD+.
Why the disclosed dose is a specific percentage of daily value
7.5mg NE · 47% DV — this specific, transparent labeling lets you compare directly against your own daily nutritional needs, unlike an undisclosed proprietary amount.
💡 Worth knowing: this ingredient connects directly to the formula's neurotransmitter support and long-term brain health claims.
