Your body can't make this vitamin, and most athletes don't realize they're running on empty until fatigue becomes chronic.

The Power of Promix B12 B12 plays a critical role in red blood cell formation, which directly impacts how much oxygen your muscles get during training. Studies show optimal B12 levels between 400-700 pg/mL correlate with better hemoglobin production and oxygen transport. Below that range, even subclinical deficiency can tank your endurance and leave you dragging through workou
