R1 Glutamine
Prolonged bouts of intense exercise don’t just drain your energy; they also deplete your body’s nutritional reserves and overcome its ability to recover. Case in point: glutamine. Overtraining can cause glutamine levels to drop, impairing performance. R1 Glutamine helps keep levels elevated.*
