To further reveal the origins of the oxidase-like activity of pFeSAN, density functional theory (DFT) calculations were performed on both Fe-N 3 and Fe-N 4 units

This targeted distribution pattern aligns with areas where antioxidant protection is most critically needed, making the supplementation more efficient and effective

These molecular adaptations are essential for enhancing muscular endurance and resistance to fatigue over time
