Product Information

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.*

We develop our own products, source the finest ingredients, and manufacture them in a FDA-inspected, NSF/GMP-compliant, and Informed-Choice certified facility.
