Fortitude L-Glutamine Powder
Support Muscle Recovery. Strengthen Immunity. Enhance Performance.
L-Glutamine is the most abundant amino acid found in the blood and plays a critical role in muscle recovery, cellular repair, and immune system function. While the body produces glutamine naturally, highly active individuals often require more than the body can supply. Supplementation provides the additional support needed to maintain performance and recovery.
Fortitude L-Glutamine Powder delivers a clean, effective source of glutamine to help support lean muscle mass, promote cell growth, and maintain overall wellness.
