Metabolic Efficiency & DNA Repair
Niacin (B3) plays a vital role in energy metabolism, DNA repair, and cellular health. It supports the conversion of food into usable energy via NAD/NADH, which are crucial cofactors in mitochondrial respiration - your cells’ energy factory.
It also contributes to healthy cholesterol levels and blood flow, improving nutrient delivery to working muscles. Niacin is especially helpful for maintaining cardiovascular endurance and mitochondrial resilience during sustained physical stress.
In short: Optimises metabolism, supports blood flow, and repairs cells under stress.
