Vitamin B12 boosts athletic performance and metabolism by acting as a critical coenzyme that converts

carbohydrates, fats, and proteinsinto cellular energy (ATP). For athletes, it is essential for producingred blood cells, which transport oxygen to working muscles to delay fatigue, and for maintaining themyelin sheathto ensure fast nerve-to-muscle signaling for coordination and power. By supportingDNA synthesisand protein metabolism, B12 also facilitates the repair of muscle tissue after intense training, helping to maintain high energy levels and metabolic efficiency.
