What It Actually Is
Niacin, also known as Vitamin B3, is an essential nutrient the body uses to make NAD+ and NADP+, molecules central to how cells generate energy.
What Research Generally Shows
Niacin's role in cellular energy metabolism is well-established. It's also studied for supporting microcirculation — small-vessel blood flow — which complements the amino acids in this formula.
Why 7.5mg Is Worth Noting
This is a modest, B-vitamin-range dose (47% of the Daily Value) — well within safe daily limits, and consistent with a supportive role rather than a standalone high-dose niacin intervention (which can cause flushing at much higher amounts).
